Diverse Pharmacological Potential of different Substituted Pyrazole Derivatives.

The chemistry of heterocyclic compounds has been a topic of research interest. Some five-membered heterocyclic compounds have been the subject of extensive research due to their different types of pharmacological effects. The five-membered nitrogen-containing heterocyclic compounds pyrazole, pyrazoline, and pyrazolone derivatives have a lot of interest in the fields of medical and agricultural chemistry due to their diverse spectrum of therapeutic activities. Various substituted pyrazole, pyrazoline, and pyrazolone compounds exhibited diverse pharmacological effects like Anti-microbial, anti-inflammatory, anti-tubercular, anti-fungal, anti-malarial, anti-diabetic, diuretic, anti-depressant, anticonvulsant, antioxidant, anti-leishmanial, antidiabetic, and antiviral, etc. In recent decades, the synthesis of numerous pyrazole, pyrazoline, and pyrazolone derivatives by different synthetic methods as well as research into their chemical and biological behavior have become more important. This review focuses on synthetic methods of the pyrazole, pyrazoline, and pyrazolone derivatives, which have significant biological properties and a variety of applications.

Novel Insecticidal Benzo[4,5]imidazo[1,2-b]pyrazole Derivatives Identified through Ring-Closure Scaffold Hopping on Fipronil.

A series of innovative benzo[4,5]imidazo[1,2-b]pyrazole scaffold containing compounds were rationally designed through a ring-closure scaffold hopping strategy and synthetized with an intermediate derivatization approach. Physicochemical properties analysis indicated the potential pesticide-likeness of the target compounds. The optimal target compound A14 showed relatively good insecticidal activity against P. xylostella, with an LC50 value of 37.58 mg/L, and demonstrated lower acute fish toxicity compared to fipronil. Docking binding mode analysis demonstrated that compound A14 bound to GABAR through a H-bond between the amide group and the residue of 6'Thr. The differences in binding modes between benzo[4,5]imidazo[1,2-b]pyrazole target compounds and fipronil may be a key factor for the reduced insecticidal activities. The elucidated binding mode and SAR profile lay a foundation for the further structural optimization of insecticidal benzo[4,5]imidazo[1,2-b]pyrazole derivatives.

Theoretical exploration of energetic molecular design strategy: functionalization of C or N and structural selection of imidazole or pyrazole.

In researching energetic materials with high energy density, it is an effective method to introduce explosophoric groups. In this study, four series of energetic compounds were designed by functionalizing with C- or N-, introducing energetic groups -CH(NO2)2, -CF(NO2)2, -C(NO2)2(NF2), -C(NO2)3, and-CH(NF2)2 into imidazole and pyrazole structures. Density functional theory was employed to optimize the structure of the target compound and subsequently to predict and evaluate its performance based on this. Meanwhile, the sensitivity of the compounds was predicted based on their electrostatic potential analysis. Following analysis of the geometric structure, detonation performance, and sensitivity of the compounds, three factors were discussed: energetic groups, functionalization methods, and skeleton structure differences. The results indicate that C-functionalization has advantages only in density, but N-functionalization is better in thermal stability, heat of formation, and sensitivity. Meanwhile, the data shows that imidazole-based compounds exhibited greater density and detonation performance in the target compounds designed within this study, while pyrazoles have a higher heat of formation and chemical stability. By analyzing the design strategy of C- or N-functionalization of novel high-energy groups on energetic imidazole or pyrazole rings and selecting a more suitable molecular construction strategy, this study provides a theoretical approach for the development of new energetic materials with excellent performance. Gaussian 09 and Multiwfn 3.8 packages are the software used for calculation, and the electrostatic potentials were depicted using the VMD program. In this study, the imidazole and pyrazole derivatives were optimized at the B3PW91/6-311G (d, p) level to acquire the relevant data for the compounds.

The Structural Activity Relationship of the target compounds were examined for their cytotoxicity. Some newly synthesized compounds showed promising antiproliferation properties when tested against HepG2 cancer cells. Compounds 4a, 5a, and 6b showed potent cytotoxicity against HepG2 with IC50 values of 4.4, 3.46 and 2.52 µM compared to Sorafenib (IC50 = 2.051 µM) and Roscovitine (IC50 = 4.18 µM). Furthermore, they were safe against the THLE2 cells with higher IC50 values. Compound 6b exhibited promising dual VEGFR2/CDK-2 inhibition activities; it had an IC50 value of 0.2 μM with VEGFR2 inhibition of 93.2%, and it had an IC50 value of 0.458 μM with CDK-2 inhibition of 88.7%. In comparison to the untreated control group (0.95%), compounds 5a (38.32%) and 6b (42.9%) considerably increased the cell population in total apoptosis. In addition, compounds 5a and 6b arrested the cell population at G0-G1 and S phases, respectively. Molecular docking experiments confirmed the virtual binding mechanism of the most active drugs, which were found to have good binding affinities with both receptor active sites.

Design, synthesis, and evaluation of a pyrazole-based corrosion inhibitor: a computational and experimental study

By employing a synergistic blend of experimental and theoretical methodologies, we investigated the corrosion inhibition efficacy of a synthesized pyrazole derivative (BM-01) in a solution of hydrochloric acid (1 M). We utilized molecular dynamics (MD) simulations, scanning electron microscopy (SEM), density functional theory (DFT), complexation, plus electrochemical impedance spectroscopy (EIS). We conducted weight loss (WL) measurements from 298 to 328 K. Inhibition efficacy reached a maximum at a BM-01 concentration of 10−3 M, achieving 90.0% (EIS), 90.40% (WL), and 90.38% (potentiodynamic polarization (PDP)). SEM unveiled the shielding of the carbon-steel surface from acid-induced damage by BM-01. The Langmuir adsorption isotherm exhibited a robust fit with a low sum of squares, standard deviation, and a high correlation coefficient. PDP findings indicated that BM-01 acted as a mixed-type inhibitor, predominantly favoring the cathodic process, suggesting potential corrosion-mitigation properties. Theoretical analyses involving DFT, MD simulations, and radial distribution function were conducted to postulate a mechanism and identify an inhibitory layer. Theoretical outcomes aligned closely with experimental data, thereby reinforcing the validity of our findings.

Synthesis and biological evaluation of some new heterocyclic compounds incorporating sulfapyridine as potential antimicrobial agents

This study investigated the cyanoacylation of the sulfapyridine moiety using cyanoacetyl pyrazole as a key synthetic intermediate for the construction of diverse bioactive scaffolds. The intermediate, 2-cyano-N-(4-(N-pyridin-2-yl) sulfamoyl) phenylacetamide, served as a valuable precursor for the synthesis of acrylamide, thiophene, thiazole, chromene, pyridone, 1,2,4-triazine, and hydrazone derivatives all incorporating the sulfapyridine core. The structural elucidation of the synthesized compounds was achieved using infrared (IR), nuclear magnetic resonance (1H and 13C), and mass spectrometry techniques. The biological activity of the newly synthesized compounds was evaluated against a panel of microorganisms, including Gram-positive bacteria (Staphylococcus aureus, Bacillus subtilis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and the fungus Candida albicans. Notably, the thiol derivative (compound 12), the pyrazole derivative (compound 15), and the 1,2,4-triazine derivatives (compound 21) exhibited significant to good antibacterial and antifungal activity. Interestingly, compounds 12 and 15 displayed a broader spectrum of activity, demonstrating efficacy against all tested microbial strains.

Drug-like screening, molecular docking, molecular dynamics simulations, and binding free energies on the interaction of pyrazole derivatives as inhibitors of lysosomal storage disorders and anticancer activity

Lysosomal membrane proteins (LAMPs) are a primary target for treating tumors because of their essential role in the cancer life cycle. In this study, some computational approaches, including drug-like screening, molecular docking, and molecular dynamics (MD) simulation studies coupled with the binding free energy, have been conducted to explore the putative binding modes of pyrazole derivatives as inhibitors of lysosomal storage disorders. Certain pyrazole derivatives outperformed typical medications in molecular docking experiments against the LAMPs receptor; among other substances, molecules CID 44555488 and 45,487,645 were deemed ideal. Additionally, these ligands (CID 44555488 and 45,487,645) were projected to be orally accessible in humans after successfully passing five separate drug-likeness criteria. In the end, it was anticipated that these ligands, CID 44555488 and 45,487,645, would have minimal human toxicity and good ADMET properties, particularly in terms of GI absorption and the lack of P-gp interaction. Compounds CID 44555488 and 45,487,645 with high predicted binding affinities were subjected to further molecular dynamics simulations based on the molecular docking data, and their potential binding mechanisms were investigated. The study's description of the structure-based drug design approach will be very helpful in the creation of novel inhibitors with excellent selectivity and potency.

Exploration of crystal structure, supramolecular organization, and computational studies of a novel pyrazole derivative: A structural and theoretical perspectives

An eminent challenge in contemporary medicine and pharmacy is the identification of powerful, biologically active, and benign anti-COVID drugs. The objective of this work is to synthesize 3-chloro-1-(3-chloropyridin-2-yl)-1H-pyrazole-5-carboxylic acid to investigate its properties using different spectroscopic methods. The crystal structure of the compound is determined using single-crystal X-ray diffraction methodology. Hirshfeld surface analysis was employed to evaluate the impact of intermolecular interactions on crystal packing. The interactions were visually depicted using 2D fingerprint plots, which highlighted the specific surface area associated with each interactant. Indications suggest that the crystal packing is mostly governed by C-H...O and N-H...O interactions, resulting in the formation of S(7) self-motif and R44(24) synthon, which greatly improve crystal stability. Density functional theory (DFT) was employed to better examine the structural and electrical characteristics. Computations were conducted at the 6–311+G(d,p) level to determine the optimal geometry, total energy, HOMO-LUMO gap, and vibrational spectra. The results showed a HOMO-LUMO gap of 3.092 eV, suggesting a moderate amount of stability. Bader et al. employed reduced density gradient (RDG) techniques and topological analysis, taking into account the quantum theory of atoms in molecules (QTAIM), to examine noncovalent interactions. Additionally, the molecule satisfies Lipinski's rule of five and exhibits encouraging pharmacokinetic activities. Additional in-silico investigations, including molecular docking, were conducted on the SARS-CoV-2 spike protein variation to assist in the advancement of enhanced vaccines and therapeutics.

Structural Perspectives in the Development of Novel EGFR Inhibitors for the Treatment of NSCLC.

Non-small cell Lung cancer (NSCLC) is the most common type of lung cancer, which is caused by high consumption of tobacco and smoking. It is an epithelial lung cancer that affects about 2.2 million people across the globe, according to International Agency for Research on Cancer (IARC). Non-small cell lung cancer is a malignant tumor caused by EGFR mutation that occurs in the in-frame deletion of exon 19 and L858R point mutation in exon 21. Presently, clinically available inhibitors of EGFR (including erlotinib, lapatinib, gefitinib, selumetinib, etc.) are not specific and responsible for undesirable adverse effects. Moreover, to solve this problem search for newer EGFR inhibitors is the utmost need for the treatment and/or management of increasing lung cancer burden. The discovery of therapeutic agents that inhibit the specific target in tumorous cells, such as EGFR, is one of the successful strategies in treating many cancer therapies, including lung cancer. The exhaustive literature survey (2018-2023) has shown the importance of medicinally privileged pyrimidine derivatives together, fused and/or clubbed with other heterocyclic rings to design and develop novel EGFR inhibitors. Pyrimidine derivatives substituted with phenylamine, indole, pyrrole, piperazine, pyrazole, thiophene, pyridine and quinazoline derivatives substituted with phenylamine, pyrimidine, morpholine, pyrrole, dioxane, acrylamide, indole, pyridine, furan, pyrimidine, pyrazole etc. are privileged heterocyclic rings shown promising activity by inhibiting EGFR and TKIs. The present review summarizes the structure-activity relationship (SAR) and enzyme inhibitory activity, including IC50 values, percentage inhibition, and kinetic studies of potential compounds from various literature. The review also includes various aspects of molecular docking studies with compounds under clinical trials and patents filed on pyrimidine-based EGFR inhibitors in treating non-small cell lung cancer. The present review may benefit the medicinal chemist for developing novel compounds such as EGFR inhibitors.
