work on N-(piperidin-4-yl)-naphthamides, the effect of substituted benzyl groups on D(2L), D(4.2), and 5-HT(2A) receptor affinity was evaluated. In the 1-naphthamide series most compounds were highly selective for D(4.2) over D(2L) and 5-HT(2A) receptors. Halogen and methyl substitution in position 3 or 4 of the benzyl group increased D(4.2) affinity. In the 2-naphthamide series a similar high D(4.2) over
在我们对N-(哌啶-4-基)-萘酰胺的研究的继续中,评估了取代的苄基对D(2L),D(4.2)和5-HT(2A)受体亲和力的影响。在1-萘酰胺系列中,大多数化合物对D(4.2)的选择性高于对D(2L)和5-HT(2A)受体的选择性。卤素和甲基取代在苄基的3或4位上增加了D(4.2)的亲和力。在2-萘酰胺系列中,保留了高于D(2L)的相似的高D(4.2)选择性,而增加了5-HT(2A)亲和力。3-甲氧基,3-甲基和4-甲基取代基有利于D(4.2)亲和力,而卤素降低了亲和力。将具有3-溴或3-甲基的2-萘甲酰胺与未取代的母体化合物相似的D(4.2)/ 5-HT(2A)配体混合。这两个系列中对D(4.2)和5-HT(2A)受体具有显着亲和力的所有化合物都是拮抗剂。
