X-Ray Crystal Structure of Betulin–DMSO Solvate

Betulin is a lupane triterpenoid [lup-20(29)-ene-3β,28-diol, C30H50O2] showing high biological activity. This activity is supposed to be strongly affected by the molecular structure of its polymorphic forms. Different solvate polymorphic forms of betulin have aroused increasing interest as the possible anticancer agents of natural origin. X-ray diffraction was used to investigate crystal structure of (1:1) betulin–DMSO solvate. Title compound...
