Dopamine transporter (DAT) inhibitors and probes act on the carrier that clears released dopamine. DAT was cloned as a cocaine-sensitive transporter, and mice lacking it show hyperlocomotion and no behavioral response to cocaine or amphetamine. The X-ray structure of the Drosophila transporter bound to an antidepressant revealed its central binding site. Listed compounds include LR1143 and SRI-32743, radafaxine hydrochloride, which inhibits dopamine and norepinephrine uptake, and DOV-102,677, which also blocks serotonin transport. IDT307 is a fluorescent transporter substrate used to measure monoamine uptake in cells.
IDT307 is a fluorescent substrate targeting the dopamine transporter (DAT). As an analog of the organic cation MPP+, it exhibits specific fluorescent properties that enable the visualization of DAT activity in various biological contexts. This compound is valuable for research applications focusing on dopamine signaling, drug interactions, and neurodegenerative disease models.
EDMA hydrochloride is a derivative of MDMA that acts primarily as a substrate for various neurotransmitter transporters, including the serotonin transporter (SERT), dopamine transporter (DAT), and norepinephrine transporter (NET). This compound exhibits significant biological activity, demonstrating 5-HT releasing capability at SERT with an EC50 of 117 nM, as well as MPP+ releasing activity at DAT (EC50 = 597 nM) and NET (EC50 = 325 nM). EDMA hydrochloride is utilized in research applications related to neurotransmitter dynamics and psychoactive substance studies.
