lines. Although there are several total synthesis routes to tubulysin and pretubulysin reported, the commercialization still has been hampered due to the complexity of the structure. To find structurally simpler pretubulysin analogs, a series of 2-(3-(methylamino)propyl)thiazole-4-carboxamides are designed and synthesized, and their anticancer activities are screened using MCF-7 (breast cancer), and NCI-H157
Pretubulysin 是微管溶素的生物合成前体,在多种肿瘤细胞系中显示出强大的生物活性。尽管已有多种微管溶素和预微管溶素全合成路线的报道,但由于结构复杂,商业化仍受到阻碍。为了寻找结构更简单的预管溶素类似物,设计并合成了一系列 2-(3-(甲基氨基)丙基)噻唑-4-甲酰胺,并使用 MCF-7(乳腺癌)和 NCI-H157 筛选了它们的抗癌活性。肺癌)细胞系。紫杉醇 (IC 50 = 0.01 µM) 和 pretubulysin 用作对照。化合物8c (IC 50 = 0.05 µM, MCF-7; 0.09 µM, NCI-H157) 和8h (IC 50 = 0.01 µM,MCF-7;0.02 µM, NCI-H157) 表现出与紫杉醇相当的某些抗肿瘤活性。Pretubulysin 的尿素类似物可能是进一步开发新型抗肿瘤药物的有前途的支架。
