title: [The synthesis of triterpenic amides based on 2,3-seco-1-cyano-19beta,28-epoxy-18alpha-olean-3-oic acid].
abstract: Novel 2,3-seco-triterpenic amides were prepared by the interaction of the chloride of 2,3-seco-l-cyano-19beta,28-epoxy-18alpha-oleane-3-oic acid with primary amines and synthetic and biogenic amino acids. A cytotoxic triterpenic conjugate with a residue of the ethyl ester of beta-alanine was found among the synthesized nitrogen-containing derivatives. Treatment with this conjugate in a concentration of 100 muM resulted in the 45.5% survival of melanoma cells in the medium.
