1-(Methylsulfonyl)piperidin-4-amine hydrochloride (cas: 651057-01-1) belongs to piperidine derivatives. The piperidine structural motif is present in numerous natural alkaloids. These include piperine, which gives black pepper its spicy taste. Piperidine derivatives bearing a masked aldehyde function in the ε-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.Application In Synthesis of 1-(Methylsulfonyl)piperidin-4-amine hydrochloride

A novel series of 6-benzhydryl-4-amino-quinolin-2-ones was discovered as cannabinoid type 1 receptor (CB1R) inverse agonists based on the high-throughput screening hit, compound 1a. Structure-activity relationships were studied to improve in vitro/in vivo pharmacol. and restrict distribution to the peripheral circulation. We adopted several strategies such as increasing topol. polar surface area, incorporating discrete polyethylene glycol side chains, and targeting P-glycoprotein (P-gp) to minimize access to the brain. Compound 6a is a P-gp substrate and a potent and highly selective CB1R inverse agonist, demonstrating excellent in vivo metabolic stability and a low brain to plasma ratio. However, brain receptor occupancy studies showed that compound 6a may accumulate in brain with repeat dosing. This was evidenced by compound 6a inhibiting food intake and inducing weight loss in diet-induced obese mice. Thus, a strategy based on P-gp efflux may not be adequate for peripheral restriction of the disclosed quinolinone series. In the experiment, the researchers used many compounds, for example, 1-(Methylsulfonyl)piperidin-4-amine hydrochloride (cas: 651057-01-1Application In Synthesis of 1-(Methylsulfonyl)piperidin-4-amine hydrochloride).
