Cariprazine free base

Additional information:
Cariprazine, also known as RGH-188 and MP-214, is an antipsychotic drug received FDA approval on September 17, 2015. Cariprazine acts as a D2 and D3 receptor partial agonist, with high selectivity towards the D3 receptor. Action on the dopaminergic systems makes it also potentially useful as an add-on therapy in major depressive disorder. Cariprazine is approved for schizophrenia and bipolar disorder. It has also been investigated as a potential adjunct in treatment-resistant major depressive disorder.|Product information|CAS Number: 839712-12-8|Molecular Weight: 427.41|Formula: C21H32Cl2N4O|Synonym:|RGH-188|MP-214|Cariprazine free base|RGH188|RGH 188|MP 214|MP214|Chemical Name: 3-((1r,4r)-4-(2-(4-(2,3-dichlorophenyl)piperazin-1-yl)ethyl)cyclohexyl)-1,1-dimethylurea|Smiles: CN(C)C(=O)N[C@@H]1CC[C@H](CC1)CCN1CCN(CC1)C1=CC=CC(Cl)=C1Cl|InChiKey: KPWSJANDNDDRMB-QAQDUYKDSA-N|InChi: InChI=1S/C21H32Cl2N4O/c1-25(2)21(28)24-17-8-6-16(7-9-17)10-11-26-12-14-27(15-13-26)19-5-3-4-18(22)20(19)23/h3-5,16-17H,6-15H2,1-2H3,(H,24,28)/t16-,17-|Technical Data|Appearance: Solid Power.|Purity: ≥98% (or refer to the Certificate of Analysis)|Solubility: Soluble in DMSO|Shipping Condition: Shipped under ambient temperature as non-hazardous chemical or refer to Certificate of Analysis|Storage Condition: Dry, dark and -20 oC for 1 year or refer to the Certificate of Analysis.|Shelf Life: ≥12 months if stored properly.|Stock Solution Storage: 0 – 4 oC for 1 month or refer to the Certificate of Analysis.|Drug Formulation: To be determined.|HS Tariff Code: 382200|How to use|In Vitro:|Cariprazine stimulates inositol phosphate (IP) formation with a high potency (pEC50 8.5) with relatively low efficacy (Emax 30%). Cariprazine, a novel candidate antipsychotic, demonstrated approximately 10-fold higher affinity for human D3 versus human D2L and human D2S receptors (pKi 10.{{Celecoxib} web|{Celecoxib} COX|{Celecoxib} Biological Activity|{Celecoxib} Description|{Celecoxib} custom synthesis|{Celecoxib} Epigenetic Reader Domain} 07, 9.{{Cobicistat} site|{Cobicistat} Metabolic Enzyme/Protease|{Cobicistat} Purity & Documentation|{Cobicistat} References|{Cobicistat} manufacturer|{Cobicistat} Epigenetic Reader Domain} 16, and 9.PMID:23310954 31, respectively). Cariprazine displays high affinity at human serotonin (5-HT) type 2B receptors (pKi 9.24) with pure antagonism. Cariprazine has lower affinity at human and rat hippocampal 5-HT1A receptors (pKi 8.59 and 8.34, respectively) and demonstrates low intrinsic efficacy. Cariprazine displays low affinity at human 5-HT2A receptors (pKi 7.73). Moderate or low affinity for histamine H1 and 5-HT2C receptors (pKi 7.63 and 6.87, respectively) suggest Cariprazine’s reduced propensity for adverse events related to these receptors[2]. Cariprazine is over sixfold more potent (EC50=1.4 nM) than Aripiprazole (EC50=9.2 nM) in inhibiting isoproterenol-induced cAMP production in HEK-293 cells.|In Vivo:|Administration of Cariprazine (30 µg/kg) reduces the striatal uptake of both radioligands to the level of nonspecific binding compared with baseline PET measurements. Cariprazine has negligible effect on the time-activity curves in the cerebellum. At doses of 5.0 and 30 µg/kg, Cariprazine causes a dose-dependent dopamine D2/D3 receptor occupancy of ~45% and ~80% for both antagonist [11C] raclopride and agonist radioligand [11C]MNPA. Receptor occupancy of dopamine D2/D3 receptors calculated using the transient equilibrium and the MRTM2 methods ranged from 5% at the lowest dose (1.0 µg/kg) to 94% at the highest dose (300 µg/kg). The effects of 5 doses of Cariprazine (ranging from 0.005 to 0.15 mg/kg) are examined on EPM behavior of wild-type mice. Whereas lower doses of Cariprazine (0.005 to 0.02 mg/kg) do not alter the time spent in open arms, the two higher doses (0.08 and 0.15 mg/kg) lead to a significant decline of this measure (ANOVA, (F(5, 52)=4.20; p=0.0032)). Moreover, the two higher doses of Cariprazine also lead to a significant decrease in the total number of arm entries (F(5, 52)=7.21; p=0.0001)) but this decrease in the total number of arm entries is largely accounted for by a significant decrease in the number of closed arm entries (F(5, 52)=11.75; p=0.0001)). The two highest doses of Cariprazine (0.08 and 0.15 mg/kg) have significant effects on locomotor activity, but doses ranging from 0.005 to 0.02 mg/kg do not affect anxiety-like behavior or locomotor activity in the EPM test.
