Abstract
Aim. To analyze the carbonyl derivatives of 7-((3-thio-4-R-4H-1,2,4-triazole-5-yl)methyl)theophylline their mother substance was synthesized and its interaction with α-haloketones series was carried out.Methods and results. The physical-chemical properties of the obtained compounds have been studied and their structures have been confirmed by elemental analysis, infrared spectrometry, 1H NMR spectrometry, UV spectrophotometry and gas chromatography mass spectrometry. Preliminary computer study of acute toxicity and biological activity has been also carried out. It has been determined that the obtained compounds may exhibit diuretic and analeptic activity and 1,2,4-triazole fragment can theoretically increase it.Conclusion. Preliminary prediction of acute toxicity has showed that the compounds are low-toxic.

Синтез и физико-химическое исследование карбонильных производных 7-((3-тио-4-R-4H-1,2,4-триазол-5-ил) метил)теофиллина. С целью исследования карбонильных производных 7-((3-тио-4-R-4H-1,2,4-триазол-5-ил)метил)теофиллина проведен синтез исходного вещества и его взаимодействие с рядом α-галогенкетонов. It is known that mesomeric effect manifestation, occurring in carbonyl group, shifts the electron density in the molecule. These derivatives spark the interest of scientific community. The manifestation of mesomeric effect in the carbonyl group provides great opportunity for the chemical molecule modification. The goal Synthesis, physical-chemical and predictive biological research of 7-((3-thio-4R-4H-1,2,4-triazole-5-yl)methyl)theophylline carbonyl derivatives
