Centanafadine is a dual inhibitor of norepinephrine (NE) dopamine (DA) transporter, also inhibits serotonin transporter (IC50s: 6 nM, 38 nM, and 83 nM for human NE, DA, and serotonin transporter).
SUN-C5174 is a sleective 5-HT2 antagonist (pA2=8.98+ -0.06). SUN C5174 showed a marked inhibitory effect on the platelet aggregation induced by serotonin in combination with collagen and adenosine diphosphate (ADP) in canine or human platelet-rich plasma
N-desmethyl Zolmitriptan (DZT) is an active metabolite of the serotonin (5-HT) receptor subtype 5-HT1B and 5-HT1D agonist zolmitriptan . DZT is an agonist of 5-HT1B receptors that induces contraction of isolated human cerebral arteries (EC50 = 100 nM).
SCH 38519 is an isochromanequinone fungal metabolite originally isolated from Thermomonospora. It inhibits aggregation induced by thrombin , as well as inhibits serotonin secretion in human platelets (IC50s = 68 and 61 μg/ml, respectively). It inhibits the growth of various Gram-negative and Gram-positive bacteria (mean MICs = 122.1 and 0.92 μg/ml, respectively).
Reduced haloperidol is an active metabolite of haloperidol . It is formed via reduction of haloperidol by ketone reductase. Reduced haloperidol inhibits radioligand binding to sigma-1 and dopamine D2 receptors (Kis = 1.4 and 31 nM, respectively) and stimulates brain-derived neurotrophic factor (BDNF) secretion from CCF-SSTG1 and U87MG astrocytic glial cells. It also inhibits norepinephrine, dopamine, and serotonin (5-HT) reuptake (Kis = 21, 25, and 33 μM, respectively, in COS-7 cells expressing the human transporters). Reduced haloperidol (0.5 mg kg) increases latency to paw withdrawal in mouse models of capsaicin- but not force-induced mechanical hypersensitivity.
5-hydroxy-Nω-methyl Tryptamine is a metabolite of serotonin in humans that has also been found in plants. It is an agonist of the 5-HT receptor subtype 5-HT7 (IC50 = 23 pM in a radioligand binding assay). 5-hydroxy-Nω-methyl Tryptamine increases intracellular cyclic AMP production in HEK293 cells expressing 5-HT7 (EC50 = 22 nM). It inhibits serotonin uptake in HEK293 cells expressing humanserotonin transporters (IC50 = 490 nM). Elevated levels of urinary 5-hydroxy-Nω-methyl tryptamine have been found in patients with schizophrenia, depression, and epilepsy.
Salvinorin A propionate is a selective partial agonist at κ1-opioid receptors (KOR) with a Ki value of 32.6 nM. It inhibits adenylate cyclase (EC50 = 4.7 nM) in HEK293 cells transfected with human KOR. It is selective for KORs over μ, δ, and ORL-1 opioid receptors and has no effect at serotonin, dopamine, muscarinic, or adrenergic receptors. In mice, salvinorin A propionate (13 μg, i.c.v.) reduces nociceptive responses in a radiant heat tail-flick assay, though not as potently as salvinorin A .
Sarizotan (EMD 128130) is an orally active compound that acts as an agonist for serotonin 5-HT 1A receptors and dopamine receptors. It has shown potent activity with IC 50 values of 6.5 nM for rat 5-HT 1A , 0.1 nM for human 5-HT 1A , 15.1 nM for rat D 2 , 17 nM for human D 2 , 6.8 nM for human D 3 , and 2.4 nM for human D 4.2 .
