A series of 1,3,4-oxadiazole-2-thiol incorporating fatty acid moieties was synthesized. The chemical structure
of the synthesized compounds was established by their spectral data, elemental analysis, and their chemical behavior.
Their thioglycosides derivatives and the analogous 1,2,4-triazole were also prepared. The in vitro cytotoxicty of the synthesized
compounds was screened against two cell lines; breast cell line MCF-7, and liver cell line HepG2. The most potent
compound is (E)-5-(heptadec-8-enyl)-1,3,4-oxadiazole-2-thiol 4f with IC50 (2.82 | µg/ml) and (3.87 µg/ml) against
breast cell line MCF-7 and liver cell line HepG2 respectively. Molecular Docking study of Bcl-2 was conducted for the
most potent compound, its analogues and the lowest cytotoxicty compound. The antimicrobial activity was also screened,
compound (E)-5-ethyl-1,3,4-oxadiazole-2-thiol 4a showed a broad spectrum of activity. A relationship between the length
of the fatty acid chain and the biological activity was noticed in the tested compounds.
一系列含有脂肪酸基团的1,3,4-噁二唑-2-硫醇化合物被合成。通过光谱数据、元素分析和化学行为确定了合成分子的化学结构。它们的硫代糖苷衍生物及其类似的1,2,4-三唑化合物也被制备。体外细胞毒性测试对两种细胞系进行了筛选:乳腺癌细胞系MCF-7和肝癌细胞系HepG2。最具活性的化合物是(E)-5-(十七碳-8-烯基)-1,3,4-噁二唑-2-硫醇4f,其对MCF-7细胞系的IC50值为2.82 µg/ml,对HepG2细胞系的IC50值为3.87 µg/ml。对最具活性化合物、其类似物和最低细胞毒性化合物的Bcl-2分子对接研究进行了开展。抗微生物活性也被筛选,化合物(E)-5-乙基-1,3,4-噁二唑-2-硫醇4a显示出广谱活性。在测试的化合物中,注意到脂肪酸链的长度与生物活性之间存在关系。
