A new strategy for converting antipsychotic drug olanzapine into PDE4 inhibitors is described via the design and Pd/C mediated synthesis of novel N-indolylmethyl olanzapine derivatives. One compound showed good inhibition (IC50 1.1 μM) and >10 fold selectivity towards PDE4B over D that was supported by docking studies. This compound also showed significant inhibition of TNF-α and no major toxicities in cell lines and a zebrafish embryo model except the teratogenic effects to be re-assessed in rodents.
描述了一种将抗精神病药物奥氮平转化为PDE4抑制剂的新策略,通过设计和Pd/C介导合成新型N-吲哚基甲基奥氮平衍生物。一种化合物表现出良好的抑制作用(IC50 1.1 μM),并且对PDE4B的选择性超过PDE4D超过10倍,这得到了对接研究的支持。该化合物还显示出显著抑制TNF-α,并且在细胞系和斑马鱼胚胎模型中没有明显的毒性,除了在啮齿动物中需要重新评估的致畸效应。
