Twenty eight new analogues were synthesized by optimizing the structure of MP-10 and their in vitro binding affinities towards PDE10A, PDE3A/B, and PDE4A/B were determined. Among these new analogues, 10a, 10b, 10d, 11a, 11b and 11d are very potent towards PDE10A and have IC50 values of 0.40 ± 0.02, 0.28 ± 0.06, 1.82 ± 0.25, 0.24 ± 0.05, 0.36 ± 0.03 and 1.78 ± 0.03 nM respectively; these six compounds displayed high selectivity for PDE10A versus PDE3A/3B/4A/4B. The promising compounds will be further validated in vivo to identify PDE10A imaging tracers.
通过优化 MP-10 的结构合成了 28 个新类似物,并测定了它们对 PDE10A、PDE3A/B 和 PDE4A/B 的体外结合亲和力。在这些新类似物中,10a、10b、10d、11a、11b 和 11d 对 PDE10A 非常有效,IC50 值为 0.40 ± 0.02、0.28 ± 0.06、1.82 ± 0.25、0.24 ± 0.05、0.36 ± 0.03 和 1.78 ± 0.0 3纳摩尔分别;与 PDE3A/3B/4A/4B 相比,这六种化合物对 PDE10A 显示出高选择性。这些有前景的化合物将在体内进一步验证,以识别 PDE10A 成像示踪剂。
