With the aim to develop inhibitors of the plasmepsin I and II aspartic proteases of the malaria parasite Plasmodium falciparum, we have synthesized sets of libraries from novel reversed-statine isosteres, using a combination of solution phase and solid phase chemistry. The synthetic strategy furnishes the library compounds in good to high overall yields and with excellent stereochemical control throughout
为了开发疟原虫恶性疟原虫的纤溶酶I和II天冬氨酸蛋白酶的抑制剂,我们使用溶液相和固相化学相结合的方法,从新型逆状态他汀类固醇合成了许多文库。合成策略使文库化合物具有良好或较高的总收率,并且在整个开发过程中均具有出色的立体化学控制。对产物的纤溶酶I和II抑制特性进行了评估,发现它们具有适度但有希望的活性。最好的抑制剂在0.5 microM的抑制剂浓度下(对Plm II的K(i)= 5.4 microM)表现出28%的纤溶酶II抑制作用。
