native HIV-1 protease and its complexes with the inhibitors suggested that the enzyme flaps are flexible. The movement at the tip of the flaps could be as large as 7 A. On the basis of this observation, cyclic cyanoguanidines have been designed, synthesized, and evaluated as HIV-1 protease (PR) inhibitors. Cyclic cyanoguanidines were found to be very potent inhibitors of HIV-1 protease. The choice of
天然HIV-1蛋白酶及其抑制剂与复合物的高分辨率X射线结构比较表明,酶瓣具有柔性。襟翼末端的运动可能高达7A。基于此观察结果,已设计,合成并评估了环状氰基胍作为HIV-1蛋白酶(PR)抑制剂。发现环状氰基胍是HIV-1蛋白酶的非常有效的抑制剂。与环状胍相比,环状氰基胍的选择是基于前者的碱性降低。具有环状氰基胍的HIV PR复合物的X射线结构研究表明,与环状脲类似,环状氰基胍也取代了独特的结构水分子。将环状氰基胍的结构-活性关系与相应的环状脲类似物的结构-活性关系进行了比较。使用高分辨率的X射线结构信息已合理化了这两个系列化合物的结合常数的差异。
