Synthesis and antitumor evaluation of some 1,3,4-oxadiazole-2(3H)-thione and 1,2,4-triazole-5(1H)-thione derivatives

Abstract: A series of 1,3,4-oxadiazole-2-thione and 1,2,4-triazole-5-thione derivatives have been successfully synthesized and studied for their antitumor activity. These compounds were prepared from carboxylic acids and chiral aminoacid esters. The prepared compounds were evaluated for their cytotoxicity against cancer in vitro using hydroxyurea (HU) as positive control. A fair number of compounds were found to have significant antitumor activity. To study the molecular basis of interaction and affinity of binding of t… Show more

“…All the compounds were evaluated in in vitro and some in the panel were found to be highly active against a mylegeneous leukaemia cell line (K-562). Results of docking studies suggested that analog 10, bearing a basic SH group in the oxadiazole or thiazole ring and NO 2 and Cl in the benzene group, could easily adopt the correct binding conformation, resulting in increased binding affinity and therefore higher cytotoxic activity [63].…”

“…Існування двох таутомерних форм для сполук 72 та 73 (тіонної -в твердому стані та тіольної -в розчині) підтверджено за наявністю на ІЧспектрах смуги поглинання в області 1 240-1 142 см -1 , що відповідає -C=S групі тіонної форми, та характерного сигналу SH-групи в області 14-15 м.ч. в 1 Н ЯМР спектрах [38]. Гідразинолізом піразоліл-фуран-2-онів 74 одержано відповідні гідразиди α-піразол-4-ілметиліден-β-ароїлпропіонатних кислот 75, які використано для синтезу неконденсованих 1,3,4-оксадіазол-піразолів 76 [39]: На основі метилового естеру (E)-α-(метоксііміно)-[(2'-бромометил)феніл]ацетатної кислоти 77 як алкілюючого реагенту у взаємодії з 5-арил-1,3,4-оксадіазол-2-тіолами 78 одержано S-бензилмеркапто-1,3,4-оксадіазоли 79, Е-конфігурацію яких підтверджено відсутністю крос-піків між резонансними протонами NOCH3-групи та ароматичного ядра на основі 2D-NOESY спектрів ПМР [40].…”
