The Antiviral and Antimalarial Prodrug Artemisinin from the Artemisia Species: A Review

Artemisinin is a truly fascinating drug in many ways. Since the unrestrained procedure of its detection, as an antimalarial drug, artemisinin has received a great deal of consideration. Recently, application of artemisinin-based combination therapy has been broadly applied for treating numerous ailments. Moreover, as an antimalarial compound, artemisinin and its associated compounds have abundant healing efficacy and can be repurposed for additional symptoms, like autoimmune infections, cancer, and viral contaminations. Recently a number of studies have highlighted the significance of the artemisinin-related compounds in SARS-CoV-2 treatment. The current review purposes to present a concise account of the history of the antiviral and antimalarial prodrugs—Artemisinin, from the Artemisia species. It is followed by its antiviral, antimalarial prospective, chemical nature and extraction procedure, photochemistry, mechanism of action, and its clinical trials and patents, and accentuates the significance of the mechanistic studies concerned for therapeutic results, both in viral and malarial circumstances.

Commercialized “Smudge Sticks” Used as Incense in the Netherlands: An Inventory of Plants and Trends Behind a New Age Fashion

Incense is essential in religious ceremonies, even in relatively new religious and spiritual movements such as New Age and Neopaganism. These garner little attention from ethnobotanists, although they trigger an international trade in wild-harvested plants. In this paper, we studied the botanical ingredients of smudge sticks (dried plant bundles burned for purification) in the Netherlands, and people’s motivations to use them posing the following questions: what plant species are included in smudge sticks? what are they used for? and are exotic plants preferred over native Dutch plant species? We visited online and physical shops in Dutch cities, acquiring a total of 29 different smudge sticks containing at least 15 species. We held semi-structured interviews with 11 users, vendors, and herbal experts, and collected data from 33 questionnaires. Salvia apiana L. was most frequently found, along with North American species of the genus Artemisia. The rise of the New Age movement resulted in North American ritual plant species being easily available in (online) shops in the Netherlands and smudge sticks being used for personal protection and cleansing. Despite the smudge sticks’ commercial demand, there is no data regarding the pressure on wild populations of species used in these bundles. For the preservation of these species it is crucial that scientific monitoring of their harvest is undertaken in the future.

Leveraging extensive soil, vegetation, fire, and land treatment data to inform restoration across the sagebrush biome

ContextWidespread ecological degradation has prompted calls for massive global investments in ecological restoration, yet limited resources necessitate efficient application of restoration efforts. In western North America, altered fire regimes are increasing the scale of restoration needed to preserve the sagebrush (Artemisia species) biome but prioritizing and implementing effective restoration is complicated by the vast and heterogeneous sagebrush landscape, which includes gradients in climate, disturbance, and species composition.ObjectivesTo develop spatially explicit and context-dependent estimates of treatment efficacy and sagebrush recovery rates.MethodsWe leveraged a suite of spatio-temporally extensive datasets to evaluate the influence of restoration treatments and environmental conditions on trends in post-disturbance sagebrush cover, with an emphasis on understanding differences between sites recovering naturally and sites receiving restoration treatments. We used estimates from these models to develop spatially explicit projections for sagebrush recovery, conditional on disturbance, restoration practice, and environmental conditions.ResultsWe found seeding Artemisia spp. increased sagebrush cover over time relative to natural recovery, but this relationship depended on spring soil moisture availability and treatment methods. Natural recovery was positively influenced by soil moisture and sagebrush cover and negatively influenced by cumulative burns and annual herbaceous cover, while the influence of perennial herbaceous cover varied with soil moisture.ConclusionsOur results provide biome-wide insights and spatially explicit tools that can inform economic cost-effectiveness analyses, restoration prioritization tools, and other scientific endeavors to ensure managers have the tools and information needed to effectively steward the sagebrush biome in a rapidly changing world.

Complete chloroplast genome sequence of Artemisia littoricola (Asteraceae) from Dokdo Island Korea: genome structure, phylogenetic analysis, and biogeography study.

The Asteraceae family, particularly the Artemisia genus, presents taxonomic challenges due to limited morphological characteristics and frequent natural hybridization. Molecular tools, such as chloroplast genome analysis, offer solutions for accurate species identification. In this study, we sequenced and annotated the chloroplast genome of Artemisia littoricola sourced from Dokdo Island, employing comparative analyses across six diverse Artemisia species. Our findings reveal conserved genome structures with variations in repeat sequences and junction boundaries. Notably, the chloroplast genome of A. littoricola spans 150,985bp, consistent with other Artemisia species, and comprises 131 genes, including 86 protein-coding, 37 tRNA, and 8 rRNA genes. Among these genes, 16 possess a single intron, while clpP and ycf3 exhibit two introns each. Furthermore, 18 genes display duplicated copies within the IR regions. Moreover, the genome possesses 42 Simple Sequence Repeats (SSRs), predominantly abundant in A/T content and located within intergenic spacer regions. The analysis of codon usage revealed that the codons for leucine were the most frequent, with a preference for ending with A/U. While the chloroplast genome exhibited conservation overall, non-coding regions showed lower conservation compared to coding regions, with the Inverted Repeat (IR) region displaying higher conservation than single-copy regions. Phylogenetic analyses position A. littoricola within subgenus Dracunculus, indicating a close relationship with A. scoparia and A. desertorum. Additionally, biogeographic reconstructions suggest ancestral origins in East Asia, emphasizing Mongolia, China (North East and North Central and South Central China), and Korea. This study underscores the importance of chloroplast genomics in understanding Artemisia diversity and evolution, offering valuable insights into taxonomy, evolutionary patterns, and biogeographic history. These findings not only enhance our understanding of Artemisia's intricate biology but also contribute to conservation efforts and facilitate the development of molecular markers for further research and applications in medicine and agriculture.

Relationship Between Genetic and Phenotypic Variations in Natural Populations of Perennial and Biennial Sagebrush.

Plant responses to environmental heterogeneity depend on life-history traits, which could relate to phenotypical and genetic characteristics. To elucidate this relationship, we examined the variation in population genetics and functional traits of short- and long-lived Artemisia species that are co-occurring in the steppes of Mongolia. Mongolian steppes represent stressful and water-limited habitats, demanding phenotypic modifications in the short term and/or genetic adaptation in the long term. However, detailed knowledge is missing about both plant phenotypic and genetic differentiation, and their interrelationships in temperate grasslands. Here, we investigated 21 populations of the widely distributed subshrub Artemisia frigida and the herbaceous biennial Artemisia scoparia. Genetic variation was assessed with newly developed simple sequence repeats (SSRs) markers. Functional trait data were collected from each individual, and data on environmental variables was collected for each population. We detected significantly higher genetic diversity in the biennial species (H E = 0.86) compared with the perennial (H E = 0.79). For both species, the largest share of genetic variation was partitioned within populations (96%). Population genetic structure in the biennial A. scoparia was weak, while the perennial A. frigida showed some spatial genetic structure, which was impacted by geographical factors, soil nutrients, and precipitation amount. Morphology-related functional traits (i.e., plant height) were predominantly associated with environmental variables rather than with genetic variation, whereas physiology-related trait (i.e., specific leaf area [SLA]) was partly genetically determined.

A second Artemisia pollen peak in autumn in Vienna: reaching the point of no return?

AbstractThe Artemisia (mugwort) pollen season usually ranges from July until September, with one peak period around mid-August in Vienna (Austria). During the last decade, Artemisia pollen was also recorded later in September. This pattern was concluded by a significant peak pollen concentration day in autumn of 2023, which exceeded the usual summer peak pollen concentration day. The Artemisia pollen data from Vienna for the last ten years (2014–2023) were therefore analysed for a temporal trend. In addition, weather data from Vienna (temperature, precipitation, and relative humidity and sun hours) were retrieved and analysed to find a possible association with Artemisia pollen indices. No significant trend could be observed regarding the Artemisia pollen season parameters and no correlation was found between the weather data and the Artemisia pollen integrals during summertime. However, a significant positive correlation was found between higher temperatures during autumn and the occurrence of Artemisia pollen during this time. This suggests that a significant change in the Artemisia pollen season can be expected during years with a mild, summer-like autumn. Until now, it is not clear which species of Artemisia cause the pollination in autumn. A. annua and A. verlotiorum are two major suspects that could have established themselves in Vienna, but further evidence is needed. Considering the impact of global climate change, the shift in the pollen season for Artemisia described in this study could represent a point of no return.

Algerian Artemisia herba-alba (Asso): Extract and Essential Oils Investigation

Background/Objective: Numerous studies have demonstrated the ethno-and pharmacological properties of various Artemisia species. However, this plant genus which grows abundantly and wildly in the ‘Tébessa’ Algerian region has not been investigated. This study focuses on the phytochemical characterization, biological activities evaluation with the antibacterial fraction identification of the aerial part aqueous extract (AE) and essential oil (EO) from Algerian Artemisia herba alba ( Aha) growing wild in the ‘Tebessa' region. Methods: Polyphenols, flavonoids, and condensed tannins were analyzed by spectrophotometer and the antimicrobial activity was determined by the gel diffusion followed by micro-dilution methods. The antioxidant effect was assayed using 2,2-diphenyl-1-picrilhidrazil (DPPH), total antioxidant capacity (TAC), and ferric reducing power (FRAP) tests. The cytotoxic and anti-leishmaniasis activities were experienced on Raw 264.7 cell line and on L. infantum and L. major promastigotes respectively. Thin-layer chromatography (TLC)/autobiography and gas chromatography-mass spectrometry (GC-MS) techniques were used to isolate and identify the antibacterial compounds. EO profile was determined by GC-MS analysis. Results: The extracts (AE and EO) demonstrated antioxidant activity, with the AE exhibiting the most pronounced levels. Both extracts showed antimicrobial activity against all the strains tested however; the EO effect was more effective, especially against the E. feacalis strain with a minimum inhibitory concentration (MIC) value of 0.0625 mg/mL. The antibacterial fraction exerted by AE towards E. feacalis was identified. AE and EO extracts showed antileishmanial activity and no toxic effect however, volatile extract was the most effective. EO profile revealed 19 identified compounds, led by camphor (51.14%), followed by 1,8 Cineole (19.30%), camphene (6.90%) and chrysanthenone (5.68%). Conclusion: As a result, the both extracts promise a high potential applications in agri-food, pharmaceutical, cosmetic sectors. This study aligns with Sustainable Development Goals (SDGs) 3, 12, and 15, emphasizing potential health benefits, the responsible use of natural resources, and biodiversity conservation.

Allocation of nitrogen and phosphorus in the leaves, stems, and roots of Artemisia: a case study in phylogenetic control.

The allocation of nitrogen (N) and phosphorus (P) among plant organs is an important strategy affecting growth and development as well as ecological processes in terrestrial ecosystems. However, due to lack of systematic investigation data, the allocation strategies of N and P in the three primary plant organs (e.g., leaves, stems and roots) are still unclear. A total of 912 individuals of 62 Artemisia species were examined across a broad environmental expanse in China, and the N and P concentrations of leaves, stems and roots were measured to explore the allocation strategies in different subgenera, ecosystem types, and local sites. Across all 62 species, the N vs. P scaling exponents for leaves, stems and roots were 0.67, 0.59 and 0.67, respectively. However, these numerical values differed among subgenera, ecosystem types, and local sites. Overall, the numerical values of N vs. P scaling exponents comply with a 2/3-power function for each Artemisia organ-type reflecting a phylogenetically conserved allocation strategy that has nevertheless diversified with respect to local environmental conditions. These results inform our understanding of N and P stoichiometric patterns and responses to abiotic factors in an ecologically broadly distributed angiosperm genus.

A comparative analysis of chloroplast genomes revealed the chloroplast heteroplasmy of Artemisia annua.

Artemisia annua L. is the main source of artemisinin, an antimalarial drug. High diversity of morphological characteristics and artemisinin contents of A. annua has affected the stable production of artemisinin while efficient discrimination method of A. annua strains is not available. The complete chloroplast (cp) genomes of 38 A. annua strains were assembled and analyzed in this study. Phylogenetic analysis of Artemisia species showed that distinct intraspecific divergence occurred in A. annua strains. A total of 38 A. annua strains were divided into two distinct lineages, one lineage containing widely-distributed strains and the other lineage only containing strains from northern China. The A. annua cp genomes ranged from 150, 953 to 150, 974bp and contained 131 genes, and no presence or absence variation of genes was observed. The IRs and SC junctions were located in rps19 and ycf1, respectively, without IR contraction observed. Rich sequence polymorphisms were observed among A. annua strains, and a total of 60 polymorphic sites representing 14 haplotypes were identified which unfolding the cpDNA heteroplasmy of A. annua. In conclusion, this study provided valuable resource for A. annua strains identification and provided new insights into the evolutionary characteristics of A. annua.

Ethnobotany of Zmeyovski pelin: A Traditional Artemisia-Flavored Wine from Bulgaria

Flavoring wine with Artemisia species, together with other aromatic herbs and/or fruits, is a practice that has evolved in different parts of Bulgaria. The aromatized wine-based beverage, called pelin, is named after the Bulgarian common name for the genus Artemisia. In this paper, we present Zmeyovski pelin, the history of which dates back to the early 20th century. We employed semi-structured interviews with 15 pelin producers from the Zmeyovo village with an age span from 44 to 83 years. The relative frequency of citation for each stated taxon was recorded. We explored the changes in the plant knowledge of the pelin makers and discussed the drivers for it. From a modern perspective, pelin can be considered a functional beverage since the aromatic plants and fruits adds a variety of biologically active substances to it, thus enhancing its health benefits. We regard the consumers’ inquiry about the benefits of the added plants as a driver for mitigating the plant awareness disparity among the local community.

Net primary productivity response to precipitation varied with different ecosystems in the Tibetan Plateau over the past two millennia

The long-term pattern of terrestrial net primary productivity (NPP) response to climate change is important for estimating aboveground biomass and assessing its ecosystem function. NPP accumulation generally increased during warming intervals. However, the relationship between terrestrial NPP and precipitation change has not been comprehensively elucidated owing to the lack of long-term quantitative NPP records. Here, we present an NPP sequence quantitatively reconstructed from annual layers of fossil pollen assemblages spanning the past two millennia. We also explore the relationship between NPP and precipitation during the periods dominated by different ecosystem types. The results revealed that the NPP variation is positively correlated with the alpine meadow, dominated by Cyperaceae species, and negatively correlated with the alpine steppe, dominated by Artemisia and Poaceae species. Additionally, the NPP sequence recorded a remarkable ∼200-year periodic oscillation, which was also recorded in the precipitation sequence. The periodic NPP showed an in-phase relationship with precipitation when the regional ecosystem was marked by the symbiosis of alpine steppe and alpine meadow, and showed an anti-phase relationship with precipitation when the regional ecosystem was dominated by alpine steppe. This study elucidates the relationships between terrestrial NPP and precipitation during the past two millennia and provides foundations for predicting future terrestrial productivity.

Identification and Characterization of Pectate Lyase as a Novel Allergen in Artemisia sieversiana Pollen

Introduction: Artemisia species are widely spread in north hemisphere. Artemisia sieversiana pollen is one of the common pollen allergens in the north of China. At present, seven allergens were identified and had been listed officially from A. sieversiana pollen, but the remaining allergens are still insufficiently studied, which need to be found. Methods: Pectate lyase was purified from the extracts of A. sieversiana pollen by anion exchange, size exclusion, and HPLC-hydrophobic interaction chromatography. The gene of A. sieversiana pectate lyase (Art si pectate lyase) was cloned and expressed in Escherichia coli. The enzyme activity and circular dichroism (CD) spectrum of natural and recombinant proteins were analyzed. The allergenicity of Art si pectate lyase was characterized by enzyme-linked immunosorbent assay (ELISA), Western blot, inhibition ELISA, and basophil activation test. The allergen’s physicochemical properties, three-dimensional structure, sequence profiles with homologous allergens and phylogenetic tree were analyzed by in silico methods. Results: Natural Art si pectate lyase (nArt si pectate lyase) was purified from A. sieversiana pollen extracts by three chromatographic strategies. The cDNA sequence of Art si pectate lyase had a 1191-bp open reading frame encoding 396 amino acids. Both natural and recombinant pectate lyase (rArt si pectate lyase) exhibited similar CD spectrum, and nArt si pectate lyase had higher enzymatic activity. Moreover, the specific immunoglobulin E (IgE) binding rate against nArt si pectate lyase and rArt si pectate lyase was determined as 40% (6/15) in patients’ serum with Artemisia species pollen allergy by ELISA. The nArt si pectate lyase and rArt si pectate lyase could inhibit 76.11% and 47.26% of IgE binding activities to the pollen extracts, respectively. Art si pectate lyase was also confirmed to activate patients’ basophils. Its structure contains a predominant motif of classic parallel helical core, consisting of three parallel β-sheets, and two highly conserved features (vWiDH, RxPxxR) which may contribute to pectate lyase activity. Moreover, Art si pectate lyase shared the highest sequence identity of 73.0% with Art v 6 among currently recognized pectate lyase allergen, both were clustered into the same branch in the phylogenetic tree. Conclusion: In this study, pectate lyase was identified and comprehensively characterized as a novel allergen in A. sieversiana pollen. The findings enriched the allergen information for this pollen and promoted the development of component-resolved diagnosis and molecular therapy of A. sieversiana pollen allergy.

Exploring Endophytic Bacteria from Artemisia spp. and Beneficial Traits on Pea Plants.

Endophytic microorganisms represent promising solutions to environmental challenges inherent in conventional agricultural practices. This study concentrates on the identification of endophytic bacteria isolated from the root, stem, and leaf tissues of four Artemisia plant species. Sixty-one strains were isolated and sequenced by 16S rDNA. Sequencing revealed diverse genera among the isolated bacteria from different Artemisia species, including Bacillus, Pseudomonas, Enterobacter, and Lysinibacillus. AR11 and VR24 obtained from the roots of A. absinthium and A. vulgaris demonstrated significant inhibition on Fusarium c.f. oxysporum mycelial growth. In addition, AR11, AR32, and CR25 exhibited significant activity in phosphatase solubilization, nitrogen fixation, and indole production, highlighting their potential to facilitate plant growth. A comparative analysis of Artemisia species showed that root isolates from A. absinthium, A. campestris, and A. vulgaris have beneficial properties for inhibiting pathogen growth and enhancing plant growth. AR11 with 100% similarity to Bacillus thuringiensis, could be considered a promising candidate for further investigation as microbial biofertilizers. This finding highlights their potential as environmentally friendly alternatives to chemical pesticides, thereby contributing to sustainable crop protection practices.

Utilizing a comparative approach to assess genome evolution during diploidization in Artemisia tridentata, a keystone species of western North America.

Polyploidization is often followed by diploidization. Diploidization is generally studied using synthetic polyploid lines and/or crop plants, but rarely using extant diploids or nonmodel plants such as Artemisia tridentata. This threatened western North American keystone species has a large genome compared to congeneric Artemisia species; dominated by diploid and tetraploid cytotypes, with multiple origins of tetraploids with genome size reduction. The genome of an A. tridentata sample was resequenced to study genome evolution and compared to that of A. annua, a diploid congener. Three diploid genomes of A. tridentata were compared to test for multiple diploidization events. The A. tridentata genome had many chromosomal rearrangements relative to that of A. annua, while large-scale synteny of A. tridentata chromosome 3 and A. annua chromosome 4 was conserved. The three A. tridentata genomes had similar sizes (4.19-4.2 Gbp), heterozygosity (2.24-2.25%), and sequence (98.73-99.15% similarity) across scaffolds, and in k-mer analyses, similar patterns of diploid heterozygous k-mers (AB = 41%, 47%, and 47%), triploid heterozygous k-mers (AAB = 18-21%), and tetraploid k-mers (AABB = 13-17%). Biallelic SNPs were evenly distributed across scaffolds for all individuals. Comparisons of transposable element (TE) content revealed differential enrichment of TE clades. Our findings suggest population-level TE differentiation after a shared polyploidization-to-diploidization event(s) and exemplify the complex processes of genome evolution. This research approached provides new resources for exploration of abiotic stress response, especially the roles of TEs in response pathways.

Analyzing the Chemical Constituents and In Vitro Biological Effects of Extracts Artemisia absinthium L. Extracts Obtained Using Different Methodologies and Solvents.

The present study aimed to investigate the chemical constituents of different extracts from aerial parts of A. absinthium and to evaluate their antioxidant and enzyme inhibition activity. Extracts were prepared by maceration, infusion or Soxhlet techniques. Results showed that the highest total phenolic and flavonoids contents was recorded respectively from the hexane extract prepared by maceration and ethyl acetate extract obtained by Soxhlet method. The characteristic compounds of Artemisia species artemetin, casticin, sesartemin and yangambin in addition to coumarins were identified in all extracts. Aqueous extract obtained by infusion exerted the highest radical scavenging and ions reducing properties while that prepared by maceration displayed the highest chelating power. Methanol extracts obtained by the two methods of extraction exerted the highest anti-Tyr activity while that obtained by maceration showed the best α-glucosidase inhibition activity. These findings indicated that A. absinthium is a rich source of bioactive molecules with possible therapeutic applications.

ДЕЙСТВИЕ ЭКСТРАКТОВ ИЗ ARTEMİSİA L. НА ПЛАЗМАТИЧЕСКУЮ МЕМБРАНУ В УСЛОВИЯХ СТРЕССА

Plant bioactive compounds are supposed to be the modifiers of structural-functional properties of cell plasma membrane under HM contamination. To test a protective effect of extracts from Artemisia L. species, possessing high adaptive potential to different soil contaminations, on electrical properties of algae cells under HM treatments was the aim of the present work. Extracts from Artemisia plants were isolated from above-ground parts of A.scoparia and A.szovitsiana by acetone hydrolyzation. Microelectrode techniques were used to study the regularities of change of membrane potential and membrane resistance of Chara gymnophylla and Nitella flexilis plasmalemma under influence of Cd, Cu, Zn, Pb and the extracts from Artemisia species. Statistically reliable hyperpolarizing effect of A.szovitsiana and A.scoparia extracts in relation to Zn and Pb was revealed, respectively. Elimination by extracts a decrease of membrane conductivity caused by Cd and Zn and also an increase of conductivity by Cu was determined. Though a high HM accumulation capacity of Artemisia L. species is noticed to not connect with protective effect of their extracts on membrane conductivity, they can be a potential source for the searching new chemical compounds which are capable to induce the plant tolerance to stress impacts.

Genetic structure and molecular analysis of the species of the genus Artemisia L. (Asteraceae) distributed in Azerbaijan

In this study, the phylogenetic relationships and genetic structure of 10 collected genotypes of Artemisia szowitziana (Besser) Grossh and Artemisia fragrans Willd. species from different regions of Azerbaijan were investigated using RAPD primers. A total of 94 amplicons were amplified using selected RAPD primers. Among them 3 band with OPA-02 primers and 12 band with OPW-17 primers were amplified. The highest polymorphism among the investigated RAPD markers was 100, 90.91 and 90%, which has been obtained by OPW-17, OPT-19, and OPT-20 primers, respectively. However, the calculated average value of polymorphism was as high as 72.79% based on 10 different RAPD markers. The average PIC (Polymorphism Information Content) value (0.864) has indicated the rich genetic diversity among the studied samples. The cluster analyses by using Jaccard similarity index and UPGMA method classified all Artemisia L. samples into 6 major groups. Principal Component Analysis (PCA) justified 74.22% of the total variance. Based on the results obtained, it has been observed that there is a wide range of diversity in the molecular level between the population of Artemisia szowitziana (1-2 and 4-6 samples) and Artemisia fragrans (3, 5, 7 and 8, 9, 10 samples) and between population of the Artemisia species in Azerbaijan.

Multitarget Mechanism of Artemisia Plants to Fight Respiratory Tract Infections Based on Network Pharmacology and Molecular Docking

Objective: To study the mechanism of Artemisia in the treatment of respiratory tract infection (RTI) by network pharmacology and molecular docking. Methods: The active constituents and targets of Artemisia were screened by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Gene Cards database to obtain disease targets associated with RTI. The key targets of intersection were used to construct the protein–protein interaction (PPI) network, and the hub gene was obtained through topological analysis to construct the pharmacology regulation network of traditional Chinese medicine. The key targets were analyzed by R language enrichment, and the regulatory network diagram of the key target function/pathway was constructed. Molecular docking verifies the binding of the drug to the target predicted by network pharmacology. Results: 144 active components of Artemisia regulated 133 target proteins related to RTI, the core components were β-sitosterol, quercetin, isorhamnetin, artemisinin, etc. Gene ontology enrichment analysis showed that Artemisia regulates receptor ligand activity, cytokine activity, and other molecular functions by acting on membrane region, membrane raft and other cellular structures in the treatment of RTI, thus affecting biological processes such as the response to drugs and bacteria-derived molecules. Kyoto Encyclopedia of Genes and Genomes enrichment analysis indicated that phosphatidylinositol 3-kinase (PI3K)-protein kinase B (Akt), tumor necrosis factor, interleukin-17 (IL-17) signaling pathway was the main pathway for RTI treatment. The molecular docking method confirmed the high affinity between the active ingredient and the RTI target. Conclusions: Artemisia species, a multitarget medication, has been shown to be a viable therapy option for RTI by network pharmacology techniques based on data mining and molecular docking approaches.
