The natural product piperine, the major bioactive alkaloid present in black pepper fruits, has the ability to modulate the functional activity of several biological targets. In this study, we have utilized the natural piperine as a tail moiety to develop new SLC-0111 analogues (6a-d, 8 and 9) as potential carbonic anhydrase inhibitors. Thereafter, different functionalities, free carboxylic acid (11a-c)
天然产物胡椒碱是黑胡椒果实中的主要生物活性生物碱,具有调节多种生物靶点功能活性的能力。在这项研究中,我们利用天然胡椒碱作为尾部分来开发新的 SLC-0111 类似物(6a-d、8和9)作为潜在的碳酸酐酶抑制剂。此后,不同的官能团,游离羧酸 ( 11a-c )、乙酰基 ( 13a ) 和乙酯 ( 13b-c ),被用作氨磺酰基官能团的生物等排体。评估了所有基于胡椒碱的衍生物对四种人类 ( h ) CA 亚型的抑制作用: hCA I、II、IX 和 XII。对于合成的初级胡椒碱磺酰胺(6a-d和8) ,观察到最好的h CA抑制活性。特别是,两种对位异构体(6c和8)在本研究中成为最有效的h CA 抑制剂,对h CA II(K I s = 93.4 和 88.6 nM)、h CA IX(K I s = 38.7 和 68.2 nM,分别)和h CA XII(K I s = 57.5 和 45.6
