In the present study, we report the design and synthesis of novel CAN508 sulfonamide-based analogues (4, 8a-e, 9a-h and 10a-e) as novel carbonic anhydrase (CA) inhibitors with potential CDK inhibitory activity. A bioisosteric replacement approach was adopted to replace the phenolic OH of CAN508 with a sulfamoyl group to afford compound 4. Thereafter, a ring-fusion approach was utilized to furnish the
在本研究中,我们报告了新型基于CAN508磺酰胺的类似物(4、8a-e,9a-h和10a-e)的设计和合成,它们是具有潜在CDK抑制活性的新型碳酸酐酶(CA)抑制剂。采用生物等位取代方法,用氨磺酰基取代CAN508的酚羟基,得到化合物4。此后,采用环融合方法制备5/5稠合的咪唑并吡唑8a-e,随后将其扩容至6/5。吡唑并嘧啶9a-h和10a-e。评价所有合成的类似物对hCA I,II,IX和XII同工型的抑制活性。与靶肿瘤相关的同工型hCA IX和XII分别被KIs范围分别为6-67.6和10.1-88.6 nM抑制。此外,评估了所有化合物的潜在CDK2和9种抑制活性。吡唑并嘧啶9d,9e和10b表现出较弱的CDK2抑制活性(分别为IC50 = 6.4、8.0和11.6μM),以及已废除的CDK9抑制活性。该趋势表明吡唑并嘧啶衍生物值得进一步优化以提供更有效的CDK2抑制剂铅。由于它们对hCA
