Based on the structural elements of bioactive indole-based compounds, a series of novel 1-substituted indole-3-carboxaldehyde thiosemicarbazones were synthesized as potential antimycobacterial and anticancer agents. The derivatives were prepared via a two-step methodology including N-alkylation(benzylation) of indole-3-carboxaldehyde and conversion of the intermediate aldehydes to corresponding thiosemicarbazones. The derivatives were evaluated for their antimycobacterial activity and compounds 3d (R = propyl) and 3q (R = 4-nitrobenzyl) were among the most potent and selective derivatives with IC50 values of 0.9 and 1.9 μg/mL respectively. The anticancer activity of the derivatives was also assessed against a panel of tumor cell lines. Compounds 3t, 3u, 3v and 3w efficiently inhibited the majority of the cancer cell lines with considerable selectivity.
基于生物活性吲哚类化合物的结构元素,合成了一系列新型1-取代吲哚-3-甲酰基缩氨基硫脲作为潜在的抗分枝杆菌和抗癌剂。这些衍生物通过两步法合成:包括吲哚-3-甲酰基的N-烷基化(苄基化)以及中间体醛转化为相应的缩氨基硫脲。评估了这些衍生物的抗分枝杆菌活性,其中化合物3d(R = 丙基)和3q(R = 4-硝基苄基)是活性最强且选择性最高的衍生物,其IC50值分别为0.9和1.9 μg/mL。还评估了这些衍生物对一组肿瘤细胞系的抗癌活性。化合物3t、3u、3v和3w能有效抑制大多数癌细胞系,并具有相当的选择性。
