Crystal structure of betulinic acid-DMSO solvate

The crystal structure of betulinic acid-DMSO (1:1) solvate has been determined. The betulinic acid, [3β-hydroxy-lup-20(29)-en-28-oic acid, C30H48O3] is considered as a promising natural agent for the clinical treatment for various types of cancer. Crystals of betulinic acid for X-ray structural analysis were grown from a DMSO-water (9:1, v/v) solution. Betulinic acid-DMSO (1:1) solvate crystallizes in the orthorhombic symmetry the P212121 space...
