Abstract

Cancer is one of the main problems of the whole world. Statistics shows that over the past 100 years the level of morbidity and mortality in the world due to the oncopathologies has moved from tenth to second place. It takes next position only after the diseases of the cardiovascular system. According to WHO data, 10 million people get sick per year. The scientists from WHO have reported that cancer mortality will increase by 45% till 2030 year compared to the level of 2007 year.

Derivatives of 1,2,4-triazole are known among physicians and clinicians of Ukraine and the whole world thanks to its antifungal, antidepressant and especially anticancer properties. Special attention of the doctors and researchers attract drugs such as anastrozole and letrozole. The pharmacological action of these drugs is associated with a combination of the nitrile groups and 1,2,4-triazole core in the molecule structures.

The aim of our research is the development of methods for obtaining new 3-((5-(hydroxy(phenyl)methine)-4-R-4H-1,2,4-triazole-3-yl)thio)aceto(propane, methylene-о-, m-, p-benzo)nitriles, establishing of their structure, physical and chemical properties.

Materials and methods of research. 3-((5-(Hydroxy(phenyl)methine)-4-R-4H-1,2,4-triazole-3-yl)thio)aceto(propane, methylene-о-, m-, p-benzo)nitriles have been obtained by action of corresponding chloronitrile (chloroacetonitrile, 3-chloropropanenitrile or 2-, 3- or 4-(chloromethylene)benzonitriles with (3-thio-4-R-4H-1,2,4-triazole-3-yl)(phenyl)methanols in medium of propanol and equimolar amounts of NaOH. The structure of the obtained compounds has been determined with the modern physical and chemical analysis methods: element analysis, IR-spectrophotometry and their individuality with thin layer chromatography.

Results and their discussion. The synthesis methods have been developed using HPLC-MS research.

Conclusions. We have obtained 13 new compounds. Its structure has been confirmed using modern physical and chemical methods of analysis. We are planning to establish acute toxicity and to study the biological activities of the synthesized compounds at the next stages of research.
