Further enhancment of analgesic activity: enkephalin analogs with terminal guanidino group.
There is a great body of evidence that a basic amino-terminal is essential for the opioid activity of enkephalins, Tyr-Gly-Gly-Phe-Met and -Leu [ 1 I, and their analogs. Removal of the amino-group of Tyr results in a practically inactive peptide [2], as does its acetylation [3]. Introduction of two methylgroups into the terminal amino-moiety brings about a substantial loss in the biological act...
متن کاملSynthesis and analgesic activity of novel Hydrazide and Hydrazine derivatives
The uses of non-steroidal anti-inflammatory drugs (NSAIDs) are limited by a variety of side effects. So research on preparing new analgesic agents is important. According to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. The final compounds 10a-10e and 15a-15d were pre...

متن کاملSynthesis and analgesic activity of new phenoxybenzylidene aroylhydrazine derivatives
A series of phenoxybenzylidene aroylhydrazine derivatives were synthesized and their structureswere confirmed using FT-IR and 1H-NMR spectroscopy. Analgesic profiles of all compoundswere examined using abdominal constriction test (writhing test). Most of synthesized compoundsinduced significant reduction in the writhing response as compared with controls. The mostactive compounds exhibited an a...
