Herein, we report the synthesis, characterization, and carbonic anhydrase (CA) inhibition of the newly synthesized Schiff’s bases 4–18 with benzenesulfonamide, methanesulfonamide, and methylsulfonylbenzene scaffolds. The compound inhibition profiles against human CA (hCA) isoforms I, II, IX, and XII were compared to those of the standard inhibitors, acetazolamide (AAZ) and SLC-0111 (a CA inhibitor
在这里,我们报告的新合成的席夫碱的合成,表征和碳酸酐酶(CA)抑制4 - 18与苯磺酰胺,甲烷和methylsulfonylbenzene支架。将针对人CA(hCA)同工型I,II,IX和XII的化合物抑制谱与标准抑制剂乙酰唑胺(AAZ)和SLC-0111(用于低氧治疗的II期临床试验中的CA抑制剂)进行了比较肿瘤)。hCA I被化合物4a-8a抑制,抑制常数(K I)在93.5-428.1 nM之间(AAZ和SLC-0111:K I,分别为250.0和5080.0 nM)。化合物4a-8a被证明是有效的hCA II抑制剂,K I范围为18.2至133.3 nM(AAZ和SLC-0111:K I分别为12.0和960.0 nM)。化合物4a-8a有效抑制hCA IX,K I范围为8.5-24.9 nM。这些值优于或等于AAZ和SLC-0111的值(分别为K I,25.0和45.0 nM)。化合物4a-8a显示出有效的hCA
