hCAIX XII-IN-4 (compound 6c) is a highly potent inhibitor of CAIX XII. It exhibits Ki values of 4.5 nM, 23.6 nM, >10000 nM, and >10000 nM for CAXII, CAIX, CAI, and CAⅡ, respectively [1].
hCAIX-IN-8 (compound 7i) is a highly potent and selective inhibitor of hCAIX, demonstrating potent inhibitory activity against CAIX with an IC50 value of 0.024 μM. It also exhibits inhibitory activity against CAII and CAVA with IC50 values of 1.99 μM and 1.10 μM, respectively. Furthermore, hCAIX-IN-8 exhibits anti-proliferative effects and low toxicity. It effectively reduces the occurrence of epithelial-to-mesenchymal transitions and promotes apoptosis. Additionally, hCAIX-IN-8 effectively inhibits cell migration and colonization potential [1].
hCAIX-IN-10 (Compound 6i) 是一种选择性碳酸酐酶 IX 和 XII 抑制剂,作用于 hCA IX (Ki: 61.5 nM) 和 hCA XII (Ki: 586.8 nM)。其中 hCA IX 和 hCA XII 是一种跨膜同工型碳酸酐酶,能够作为一些类型肿瘤的生物标志物。hCA XII 有助于正常细胞和肿瘤细胞中酸碱平衡的维持。
