Novel 3-aryl indoles as progesterone receptor antagonists for uterine fibroids.

We report the synthesis and characterization of novel 3-aryl indoles as potent and efficacious progesterone receptor (PR) antagonists with potential for the treatment of uterine fibroids. These compounds demonstrated excellent selectivity over other steroid nuclear hormone receptors such as the mineralocorticoid receptor (MR). They were prepared from 2-bromo-6-nitro indole in four to six steps using a Suzuki cross-coupling as the key step. Compound 8f was orally active in the complement 3 model of progesterone antagonism in the rat uterus and demonstrated partial antagonism in the McPhail model of progesterone activity.

Design and synthesis of dual peroxisome proliferator-activated receptors gamma and delta agonists as novel euglycemic agents with a reduced weight gain profile.

The design and synthesis of the dual peroxisome proliferator-activated receptor (PPAR) gamma/delta agonist (R)-3-{4-[3-(4-chloro-2-phenoxy-phenoxy)-butoxy]-2-ethyl-phenyl}-propionic acid (20) for the treatment of type 2 diabetes and associated dyslipidemia is described. The compound possesses a potent dual hPPAR gamma/delta agonist profile (IC(50) = 19 nM/4 nM; EC(50) = 102 nM/6 nM for hPPARgamma and hPPARdelta, respectively). In preclinical models, the compound improves insulin sensitivity and reverses diabetic hyperglycemia with less weight gain at a given level of glucose control relative to rosiglitazone.
