D-5-Hydroxytryptophan D-5-HTP; 5-Hydroxy-D-tryptophan	5-HT Receptor	Neurological Disease
D-5-Hydroxytryptophan (D-5-HTP) is the D-isomer of 5-HTP and can be isolated from DL-5-hydroxytryptophan by continuous separation. Compared with intraperitoneal administration of L-5-Hydroxytryptophan, which can induce dose-dependent backward walking behavior in mice, D-5-Hydroxytryptophan has no significant effect on mouse behavior and is a negative control. D-5-Hydroxytryptophan is also a *5-HT* ligand, capable of binding to the 5-HT site with affinity in the micromolar range .

HY-101480

Xylamidine	5-HT Receptor	Neurological Disease
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.

LEK 8804	5-HT Receptor	Others
LEK 8804 is a compound with 5-HT1A receptor agonist and 5-HT2 receptor antagonist properties, and has the activity of modulating related receptor-mediated behavioral responses. LEK 8804 can induce spontaneous tail-flick response in rats in a dose-dependent manner, showing complete 5-HT1A agonist activity, and can inhibit 5-HTP-induced head twitch response in mice, probably through antagonism of 5-HT2 receptors rather than agonism of 5-HT1A receptors.
