heterocyclic derivatives, characterized by different central cores, were synthesized and tested for their affinity toward the human CB1 and CB2 cannabinoid receptors. The obtained results suggest that the new series of quinolin-2(1H)-on-3-carboxamides, 4-hydroxy-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxamides and 1,2-dihydro-2-oxopyridine-3-carboxamides represent novel scaffolds very suitable for the development
由于该受体在几种生理病理过程中的潜在作用,其CB2受体配体正变得越来越有吸引力。使用我们先前描述的一系列1,8-萘啶-2(1 H)-on-3-羧酰胺类作为先导类,合成了几种具有不同中心核的氮杂环衍生物,并测试了它们对人CB1的亲和力和CB2大麻素受体。获得的结果表明,新系列的喹啉2(1 H-on-3-羧酰胺,4-羟基-2-氧代-1,2-二氢-1,8-萘吡啶-3-羧酰胺和1,2-二氢-2-氧吡啶-3-羧酰胺代表非常合适的新型支架用于开发有前途的CB2配体。此外,新合成的CB2配体抑制了几种癌细胞的增殖。特别地,已证明在DU-145细胞系中这些配体发挥CB2介导的抗增殖作用并降低CB2受体表达水平。
