Abstract:
Provided are β-substituted Morita-Baylis-Hillman (MBH) derivatives, pharmaceutically acceptable salts, hydrates, solvates and stereoisomers thereof. The derivatives may be prepared by preparing β-iodo-MBH esters from a variety of carbonyl compounds such as aldehydes and ketones, or imines in the presence of a Lewis acid as a basic backbone, and substituting iodide on a vinyl position with a variety of substituents. In addition, the β-substituted MBH derivatives have an excellent pharmaceutical effect in preventing and treating cancer.
Abstract:
Provided is a polypeptide extract containing a polypeptide with a molecular weight of 1 ,000 to 3,000 Da, obtained by adding detoxified swellfish to water in a ratio of 50-1 ,500 g :1 L, followed by distillation.
Abstract:
The present invention relates to novel octahydro indeno derivatives, pharmaceutically acceptable salts, hydrates, solvates and stereoisomers thereof, and pharmaceutical compositions for treating or preventing cancer comprising the same. Since the compounds according to the present invention have high cytotoxicity against cancer cells, they may be usefully used as medical uses such as anticancer agents or antibiotics.
