Camptothecin (CPT) has been shown to block disassembly of the topoisomerase I (Topo I)/DNA cleavable complex. However, the poor aqueous solubility, intrinsic instability, and severe toxicity of CPTs have limited their clinical applications. Herein, we report the design and synthesis of H2O-soluble and orally bioavailable hexacyclic CPT derivatives. By analysis of a virtual chemical library and cytotoxicity
喜树碱(CPT)已显示出可阻断拓扑异构酶I(Topo I)/ DNA可裂解复合物的分解。然而,CPT的差的水溶性,固有的不稳定性和严重的毒性限制了它们的临床应用。在这里,我们报告H 2 O可溶性和口服生物可利用的六环CPT衍生物的设计和合成。通过对虚拟化学文库的分析和体外细胞毒性筛选,将9和11鉴定为潜在的前药,并选择用于体内进一步表征。两种化合物在动物中均表现出显着的抗癌和抗炎功效,并具有类似药物的特性。
