HIV protease inhibitors are among the most powerful drugs in suppressing HIV in human patients. However, HIV developed resistance to all protease inhibitor drugs so far marketed or used in clinical trials. HIV generates resistance by mutating its protease. The strains of HIV containing mutant proteases less vulnerable to inhibitor drug are able to replicate better and maintain the infection. No effective principle exists for the design of resistance-proof HIV protease inhibitors (HIVPr). A new inhibitor has been developed based on a new concept for designing resistance invulnerable HIVPr inhibitors. In vitro data have shown that this inhibitor is effective against many known HIVPr mutants resistant to other HIVPr inhibitor drugs. The new concept is, therefore, generally applicable for the design of other resistance invulnerable HIVPr inhibitor drugs.
HIV蛋白酶抑制剂是抑制人类HIV最强大的药物之一。然而,迄今为止市场上或在临床试验中使用的所有蛋白酶抑制剂药物对HIV都产生了抗药性。HIV通过突变其蛋白酶来产生抗药性。含有对抑制剂药物不太脆弱的突变蛋白酶的HIV菌株能够更好地复制并维持感染。目前尚无有效的原则用于设计抗耐药性的HIV蛋白酶抑制剂(HIVPr)。基于设计抗耐药性的HIVPr抑制剂的新概念已经开发出一种新的抑制剂。体外数据显示,这种抑制剂对许多已知对其他HIVPr抑制剂药物产生抗药性的HIVPr突变体具有有效性。因此,这种新概念通常适用于设计其他抗耐药性的HIVPr抑制剂药物。
