四个12-O-十四烷酰基-13-O-乙酰佛波醇型肿瘤促进剂--teleocidin、佛波醇酯、阿朴西毒素和巨大戟二萜醇酯--被叠加在一起，试图理解它们共同的生物活性，假设它们可以结合到相同的受体位点。一种方法，使用三维计算机图形被应用于叠加分子和受体映射。该方法的主要特点是分子在物理和化学性质的空间排列方面是叠加的，而不是像传统方法那样在原子位置方面。这导致了有效的肿瘤促进活性所需的共同结构特征的成功提取：两个氢供体，一个氢受体和一个大的亲脂基团。它们的相互空间排列对于生物活动是最重要的。
Four 12-O-tetradecanoyl-13-O-acetylphorbol-type tumor promoters--teleocidin, phorbol ester, aplysiatoxin, and ingenol ester--are superposed in an attempt to understand their common biological activity on the assumption that they may bind to the same receptor site. A method using three-dimensional computer graphics was applied for superposing molecules and receptor mapping. The main feature of the method is that molecules are superposed in terms of spatial arrangement of physical and chemical properties but not in terms of the atomic positions as in conventional methods. This led to successful extraction of common structural features required for potent tumor-promoting activity: two hydrogen donors, a hydrogen acceptor, and a large lipophilic group. Their mutual spatial arrangements are most important for biological activity.
