The synthesis of triterpenic amides on the basis of 2,3-seco-1-cyano-19β,28-epoxy-18α-oleane-3-oic acid
2010
Novel 2,3-seco-triterpenic amides were prepared by the interaction of the chloride of 1-cyano-19β,28-epoxy-18α-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 β-alanine was found among the synthesized nitrogen-containing derivatives. Treatment with this conjugate in a concentration of 100 μM resulted in the 45.5% survival of melanoma cells in the medium.
