The synthesis of anithiactin A has been achieved in four steps. Several closely related analogues were synthesised and their biological activity against colon and breast cancer cell lines evaluated. Anithiactin A was found not to be cytotoxic even at a high concentration (100 μM); however, two 4-substituted phenyl thiazoles were found to be moderately cytotoxic at 10 μM. Based on these results, 4-substitution on the phenyl group appears to be critical for cytotoxicity. However, the exact electronic and structural requirements are unclear.
Anithiactin A 的合成分为四个步骤。合成了几种密切相关的类似物,并评估了它们对结肠癌和乳腺癌细胞系的生物活性。结果发现,即使在高浓度(100 μM)下,连翘素 A 也没有细胞毒性;但是,在 10 μM 的浓度下,两个 4 取代苯基噻唑具有中度细胞毒性。根据这些结果,苯基上的 4 取代似乎是细胞毒性的关键。然而,确切的电子和结构要求尚不清楚。
