Synthesis and pharmacological activity of amides and the ozonolysis product of maleopimaric acid
2010
The synthesis of a new group of maleopimaric acid amides containing fragments of methyl ethers of amino acids, aliphatic amines, imidazole, and N-methylpiperazine was carried out. The ozonolysis of methylmaleopimarate occurs via the cleavage of the double bond C18(19) and the opening of an anhydrous ring with the formation of secotriacid. As a result of the screening of the anti-inflammatory and antiulcer activity of maleopimaric acid derivatives, new effective compounds such as maleopimaric acid and its methyl ether, a product of ozonolysis—diterpenic secotriacid—and maleopimaric acid amide with L-leucine were found. An important advantage of the studied compounds is the low toxicity and the presence of bidirectional activity in the absence of adverse effects on the animal.
