Pyrazole and Isoxazole Derivatives as New, Potent, and Selective 20-Hydroxy-5,8,11,14-eicosatetraenoic Acid Synthase Inhibitors
摘要:
In a previous paper, we reported the N-hydroxyformamidine derivative HET0016 as a potent and selective 20-HETE synthase inhibitor. Despite its attraction as a potential therapeutic agent for cerebral diseases, the preparation of an injectable formulation of HET0016 was limited by its poor solubility under neutral conditions and instability under acidic conditions. The instability of HET0016 in acidic conditions is due to the N-hydroxyformamidine moiety, which is considered to be essential for the potent and selective activity seen in our previous study. The activity was maintained when the N-hydroxyformamidine moiety was replaced by an imidazole ring (3a; IC50 = 5.7 +/- 1.0 nM), but this was associated with a loss of selectivity for cytochrome P450s (CYPs). However, other azole derivatives such as isoxazole derivative 23 (IC50 value 38 +/- 10 nM) and pyrazole derivative 24 (IC50 value 23 +/- 12 nM) showed potent and selective activities with improved stability.

The present invention provides a method for preferentially reducing the proliferation of cystic epithelial cells in the kidney or bile duct in a mammal in need thereof by administering a 20-HETE synthesizing enzyme inhibitor or a 20-HETE antagonist to the mammal in an amount sufficient to preferentially reduce the proliferation of cystic epithelial cells over normal epithelial cells such as tubule epithelial cells in the kidney or bile duct. The present invention also provides a method for preventing or treating autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD), ARPKD associated congenital hepatic fibrosis, ARPKD associated Caroli's disease, or cholangiocarcinoma in a mammal in need thereof by administering a 20-HETE synthesizing enzyme inhibitor or a 20-HETE antagonist to the mammal in an amount sufficient to prevent or treat the disease.
