Xylamidine tosylate

Xylamidine tosylate is a serotonin inhibitor with reproductive activity. Xylamidine tosylate can affect reproductive processes and may be used as an experimental tool in related research. The mechanism of action of Xylamidine tosylate involves the regulation of the serotonin system .

Xylamidine is a peripheral 5-HT receptor antagonist used to investigate possible peripheral appetite suppressant effects of 5-hydroxytryptophan (5-HTP) and fenfluramine. In a 1-hour food intake test, xylamidine attenuated the decrease in food intake induced by 5-HT and 5-HTP, but had no effect on fenfluramine, suggesting that the appetite suppressant effect of 5-HTP is mediated in part through peripheral 5-HT receptors. Microstructural analysis revealed that 5-HTP and fenfluramine induced a decrease in food intake rate and a reduction in feeding batch size. Xylamidine reversed the effects of 5-HTP on food intake rate and induced a slight increase in feeding batch size itself, thus, the peripheral effect of 5-HTP appears to be to slow food intake rate. No effect of xylamidine on fenfluramine-induced changes in feeding was observed. The results suggest that the appetite suppressant effects of 5-HTP and fenfluramine are differentiated based on the peripheral effects of 5-HTP. The peripheral effects of 5-HTP are distinct from the previously reported 5-HT-induced decreases in feeding batch size and duration. Possible mechanisms underlying the differences in peripheral effects of 5-HT and 5-HTP are discussed.
