Preclinical metabolism and pharmacokinetics of NVS-CRF38, a potent and orally bioavailable corticotropin-releasing factor receptor 1 antagonist was written by Stringer, Rowan A.;Weber, Eckhard;Culshaw, Andrew;McKenna, Jeff;Williams, Gareth;Rose, Jonathan;Sohal, Bindi. And the article was included in Xenobiotica in 2014.Recommanded Product: 1614-12-6 This article mentions the following:
1. The pharmacokinetic properties and metabolism of NVS-CRF38 [7-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-3-(4-methoxy-2-methylphenyl)-2,6-dimethylpyrazolo[5,1-b]oxazole], a novel corticotropin-releasing factor receptor 1 (CRF1) antagonist, were determined in vitro and in animals. 2. NVS-CRF38 undergoes near complete absorption in rats and dogs. In both species the compound has low hepatic extraction and is extensively distributed to tissues. 3. In rat and human hepatic microsomes and cryopreserved hepatocytes from rat, dog, monkey and human, NVS-CRF38 was metabolized to form O-desmethyl NVS-CRF38 (M7) and several oxygen adducts (M1, M3, M4, M5 and M6). In hepatocytes further metabolites were observed, specifically the carboxylic acid (M2) and conjugates (sulfate and glucuronide) of M7. 4. Formation of primary metabolites in hepatocytes was blocked by the cytochrome P 450 enzyme (P 450) suicide inhibitor 1-aminobenzotriazole, implicating P 450 enzymes in the primary metabolism of this compound 5. NVS-CRF38 is weakly bound to plasma proteins from rat (fub = 0.19), dog (fub = 0.25), monkey (fub = 0.20) and humans (fub = 0.23). Blood-to-plasma partition for NVS-CRF38 approaches unity in rat and human blood. 6. The hepatic clearance of NVS-CRF38 in humans is predicted to be low (extraction ratio ∼ 0.2) based on scaling from drug depletion profiles in hepatic microsomes. In the experiment, the researchers used many compounds, for example, 1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6Recommanded Product: 1614-12-6).
1H-Benzo[d][1,2,3]triazol-1-amine (cas: 1614-12-6) belongs to triazole derivatives. Among the nitrogen-containing heterocyclic compounds, triazoles emerge with superior pharmacological applications. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Recommanded Product: 1614-12-6
