Abstract
A molecular modeling study of two alkaloids, tubulosine and psychotrine, isolated from the sap of Pogonopus speciosus, and other related ipecac alkaloids, showed that these flexible alkaloids favor a nonplanar structure. The biologically active compounds had conformations with a similar angle between aromatic ring A, the nitrogen in ring B, and ring D. This angle was related to the biological activity reported for these compounds. Our results support the hypothesis of two different types of receptor interactions, one for the nonplanar compounds and another for the planar compounds.Entities:
