DC72326 Tabernanthalog Tabernanthalog is a water-soluble, non-hallucinogenic and non-toxic analogue of ibogaine. Tabernanthalog is a 5-HT2A agonist. Tabernanthalog is found to promote structural neural plasticity, reduce alcohol- and heroin-seeking behaviour, and produce antidepressant-like effects in rodents.
DC71747 Aripiprazole monohydrate Aripiprazole (OPC-14597) monohydrate, an atypical antipsychotic, is a potent and high-affinity dopamine D2 receptor partial agonist. Aripiprazole monohydrate is an inverse agonist at 5-HT2B and 5-HT2A receptors and displays partial agonist actions at 5-HT1A, 5-HT2C, D3, and D4 receptors. Aripiprazole monohydrate can be used for the research of schizophrenia and COVID19.
DC71510 Ansofaxine hydrochloride Ansofaxine hydrochloride (LY03005, LPM570065), a triple reuptake inhibitor, inhibits serotonin, dopamine and norepinephrine reuptake with IC50 values of 723, 491 and 763 nM, respectively.
DC71221 CJ033466 CJ033466 is a novel and selective 5-HT4 receptor partial agonist with an EC50 of 9 nM and has gastroprokinetic effect.
DC70441 GR-127935 GR-127935 is a potent and selective 5-HT1B/1D receptor antagonist with pKi of 8.5 for both guinea pig 5-HT1D and rat 5-HT1B receptor; displays >100-fold selectivity over 5HT1A, 5-HT2A, 5-HT2C receptors and other receptor types; blocks porcine carotid vascular response to sumatriptan in vivo; orally bioavailable and centrally active.
DC70176 AGH-107 AGH-107 is a potent, selective 5-HT7 receptor agonist with Ki of 6 nM and EC50 of 19 nM, 176-fold selectivity over 5-HT1AR.AGH-107 exhibited high selectivity over related CNS targets, high metabolic stability and low toxicity in HEK-293 and HepG2 cell cultures.
DC49608 RS 67333 hydrochloride RS 67333 hydrochloride is a potent and selective 5-HT4 receptor (5-HT4R) partial agonist with a pKi of 8.7 in guinea-pig striatum. RS 67333 hydrochloride exhibits lower affinities at several other receptors including 5-HT1A, 5-HT1D, 5-HT2A, 5-HT2C, dopamine D1, D2 and muscarinic M1-M3 receptors. RS 67333 hydrochloride has neuroprotective effects, and can be used for Alzheimer's disease research.
