  The invention provides methods for treating an individual having a retinoid responsive disorder. In one embodiment, a method involves administering to the individual an effective amount of a selective CYP26B inhibitor, the selective CYP26B inhibitor having at least 10-fold selectivity for CYP26B relative to CYP26A. In another embodiment, a method involves administering to the individual an effective amount of a selective CYP26A inhibitor, the selective CYP26A inhibitor having a chemical formula set forth in the specification. The invention further provides screening methods for identifying a selective CYP26A inhibitor or selective CYP26B inhibitor.

  本发明提供了一种治疗患有视黄酸反应性障碍的个体的方法。在一个实施例中，一种方法包括向个体施用有效量的选择性CYP26B抑制剂，所述选择性CYP26B抑制剂相对于CYP26A至少具有10倍的选择性。在另一个实施例中，一种方法包括向个体施用有效量的选择性CYP26A抑制剂，所述选择性CYP26A抑制剂的化学公式如说明书所述。本发明还提供了用于识别选择性CYP26A抑制剂或选择性CYP26B抑制剂的筛选方法。
