Hydroxyacetophenone-derived antagonists of the peptidoleukotrienes
摘要:
Considerations of the possible similarities between leukotriene D4 and its prototypical antagonist, FPL 55712, led to the development of a new series of leukotriene antagonists incorporating a hydroxyacetophenone group (e.g., the toluic acids 16 and 18). Although considerable attention has focused on FPL 55712-derived analogues, only limited investigations into alternatives for the standard 4-acetyl-3-hydroxy-2-propylphenoxy moiety have been reported. Therefore, an extensive study of modifications to the hydroxyacetophenone portion of toluic acid 18 was undertaken. Although no viable alternative to the 3-hydroxy moiety was discovered, replacements for the 2-propyl group (34, 37) and the 4-acetyl functionality (56, 59) yielded potent antagonists. A number of compounds exhibited longer duration of action in vivo than FPL 55712.
Beginning with the weakly active lead structure 1, a new series of WAR agonists was developed. In vivo glucose and triglyceride lowering activity was obtained by homologation and oxamination to 3, then conversion to substituted benzisoxazoles 4 and 5. Further manipulation afforded benzofurans 6 and 7. Compound 7 was of comparable potency as a glucose and triglyceride lowering agent in insulin resistant rodents to BRL 49653.

A series of 2-aryloxy-2-methyl-propionic acid compounds and related analogues were designed, synthesized, and evaluated for their PPAR agonist activities. 2-[(5,7-Dipropyl-3-trifluoromethyl)-benzisoxazol-6-yloxy]-2-methylpropionic acid (4) was identified as a PPAR alpha/gamma dual agonist with relative PPAR alpha selectivity and demonstrated potent efficacy in lowering both glucose and lipids in animal models without causing body weight gain. The PPAR alpha activity of 4 appeared to have played a significant role in lowering glucose levels in db/db mice.
