a series of 6-4-[(3-fluorobenzyl)oxy]phenoxy}nicotinamide derivatives, and evaluated their inhibitory activity against the reverse and forward modes of NCX. N-(3-Aminobenzyl)-6-4-[(3-fluorobenzyl)oxy]phenoxy}nicotinamide (8) was shown to be a potent inhibitor of reverse NCX activity, with an IC50 value of 0.24 microM. A QSAR study showed that inhibition of reverse NCX activity by 6-4-[(3-fluoro
钠钙交换剂(NCX)输送Na +和Ca2 +离子,并控制心肌细胞中Ca2 +的浓度。钙超载是通过激活反向NCX引起的,并导致心力衰竭时的再灌注损伤。因此,NCX是预防和治疗再灌注性心律不齐,心肌挛缩和坏死的有吸引力的靶标。我们已经合成了一系列的6- 4-[((3-氟苄基)氧基]苯氧基}烟酰胺衍生物,并评估了它们对NCX的反向和正向模式的抑制活性。N-(3-氨基苄基)-6- 4-[((3-氟苄基)氧基]苯氧基}烟酰胺(8)被证明是反向NCX活性的有效抑制剂,IC50值为0.24 microM。
