series of structurally novel benzoxaborole derivatives were designed, synthesized and biologically evaluated as PDE4 inhibitors for battling atopic dermatitis (AD). Among them, the majority exhibited superior PDE4B inhibitory activities to that of the lead compound Crisaborole, an approved PDE4 inhibitor. In particular, 72, the most potent PDE4B inhibitor throughout this series, displayed 136-fold
在这项工作中,设计,合成和生物学评估了一系列结构新颖的苯并x硼烷衍生物作为抗特应性皮炎(AD)的PDE4抑制剂。在它们之中,大多数表现出比已批准的PDE4抑制剂先导化合物Crisaborole更好的PDE4B抑制活性。特别是,在整个系列中最有效的PDE4B抑制剂72 与Crisaborole(IC 50 = 57.20 nM)相比,显示出136倍的酶活性(IC 50 = 0.42 nM)改善的同工型特异性。在佛波酯(PMA)诱导的小鼠耳部水肿模型中,在相同剂量下72的功效显着大于Crisaborole(P <0.05)。而且, 在卡泊三醇诱导的小鼠AD模型中,软膏72的药效比Crisaborole的软膏显着增强(P <0.05)。除有效的体外和体内活性外,72在重复的口服剂量毒性研究中显示出良好的安全性,并且未显示出光毒性。凭借上述引人入胜的生物学性能,作为一种新型的抗AD治疗剂,值得进一步研究72。
