N-(5-substituted) thiophene-2-alkylsulfonamides as potent inhibitors of 5-lipoxygenase
摘要:
Compound 4k N-[5-(4-fluoro) phenoxythien-2-yl] methanesulfonamide is representative of a new class of potent inhibitors of 5-lipoxygenase (5-LO). These versatile compounds exhibit dose-dependent inhibition of 5-LO with IC(50)s ranging from 20-100 nM in the rat basophilic leukemia (RBL-1) cell homogenate assay and submicromolar IC,,s in both the RBL-1 and human peripheral blood leukocyte (PBL) whole cell assays. Compound 4k also showed significant anti-inflammatory activity in the adjuvant arthritic rat at an oral dose of 3 mg/kg. (C) 1997 Elsevier Science Ltd.

Heteroaryl and aliphatic analogs of diarylurea-based cannabinoid 1 receptor (CB1 R) allosteric modulators of formula (I) are described. Exemplary analogs can provide improved potencies and pharmacokinetic properties. Methods of using the analogs to treat diseases mediated by CB1 R, such as substance abuse and obesity are described.

We previously reported diarylurea derivatives as cannabinoid type-1 receptor (CB1) allosteric modulators, which were effective in attenuating cocaine-seeking behavior. Herein, we extended the structure-activity relationships of PSNCBAM-1 (2) at the central phenyl ring directly connected to the urea moiety. Replacement with a thiophene ring led to 11 with improved or comparable potencies in calcium
