There are four configurational isomers and every configuration has several different conformers of germacrane derivatives, which tend to exist as the most stable conformers.

This method is demonstrated by an example that sixteen virtual bio-active compounds were generated starting from HIV-1 protease inhibitors pharmacophore in this work. The results of conformation analysis showed that the pharmacophore is contained in the favorite conformers of the generated structure.

经过对HIV-1蛋白酶抑制剂药效团进行虚拟活性化合物生成，得到了16个虚拟活性化合物，通过构象分析发现生成的化合物满足药效团的限制条件。
