The enzyme isoprenylcysteine carboxyl methyltransferase (Icmt) plays an important role in the post-translational modification of proteins involved in the regulation of cell growth and oncogenesis. The biological consequences of Icmt inhibition strongly implicate the enzyme as a potential therapeutic target for cancer and provide a compelling rationale for developing specific Icmt inhibitors as anti-cancer
异戊烯基半胱氨酸羧基甲基转移酶(Icmt)在蛋白质的翻译后修饰中起重要作用,该蛋白质参与调节细胞的生长和致癌作用。Icmt抑制的生物学结果强烈暗示了该酶可能成为癌症的潜在治疗靶标,并为开发特定的Icmt抑制剂作为抗癌剂提供了令人信服的理由。我们在这里报告了已知的Icmt抑制剂cysmethynil的系统修饰,以产生类似物15大大提高了溶解度和PAMPA渗透性,同时获得了Icmt抑制和基于细胞的抗增殖活性。修改涉及叔胺取代cysmethynil的酰胺侧链,并引入代替氨基嘧啶环米甲苯基。弱碱性和极性氨基嘧啶环的存在对最终化合物的效价和类药物特性有显着贡献。
