We report the design, synthetic route, and cytotoxicity of a library of 49 newly synthesized tricyclic oxazolo[5,4-d]pyrimidines. The condensed pyrimidinones were constructed from ethyl 5-aminooxazole-4-carboxylate building blocks. A tricyclic ring system was built using the naturally occurring mackinazolinone alkaloid with a focus on the molecular diversity at position C-2 of the oxazole ring. Synthesized
我们报告了 49 个新合成的三环恶唑并[5,4- d ]嘧啶库的设计、合成路线和细胞毒性。缩合嘧啶酮由 5-氨基恶唑-4-羧酸乙酯结构单元构成。使用天然存在的麦金唑啉酮生物碱构建了三环系统,重点关注恶唑环 C-2 位的分子多样性。合成的化合物在体外针对一组人类癌细胞系进行了评估,包括 MCF-7(乳腺)、HeLa(宫颈)和 A549(肺)。结果表明,在恶唑环的 C-2 位取代卤素相关的芳香片段可作为有希望的抗癌药物候选者。
