order to identify potential calpain and cathepsin inhibitors we prepared 12 dihydroxychalcone analogues and tested their ability to inhibit μ-calpain, m-calpain, cathepsins B and L. In the calpain inhibition test, compound 10 exhibited the most active inhibitory activity against m-calpain with an IC50 value of 25.25 ± 0.901 μM. With respect to inhibition of cathepsins B and L, compound 13 exhibited
为了鉴定潜在的钙蛋白酶和组织蛋白酶抑制剂,我们制备了12种二羟基查耳酮类似物,并测试了它们抑制μ-钙蛋白酶,m-钙蛋白酶,组织蛋白酶B和L的能力。在钙蛋白酶抑制试验中,化合物10对m-的活性最强。钙蛋白酶的IC 50值为25.25±0.901μM。关于组织蛋白酶B和L的抑制,化合物13对组织蛋白酶L表现出最强的抑制活性,对组织蛋白酶B表现出中等的抑制活性(IC 50)值分别为2.80±0.100和11.47±0.087μM。我们的结果表明,通过适当调节结构和/或结合对特定钙蛋白酶和组织蛋白酶抑制有效的官能团的基本方面,开发钙蛋白酶和组织蛋白酶双重抑制剂的可能性。
