To test growth effects of angiotensin II (ANG II) in porcine vascular smooth muscle cells (VSMC) and potential ANG II synergy with epidermal growth factor (EGF), we exposed subconfluent, near-quiescent porcine aortic VSMC to ANG II, EGF, or ANG II + EGF (each 10(-9) M) in Dulbecco's modified Eagle's-Ham's F-12 medium with insulin + 0.4% fetal calf serum… (More)
High-throughput screening has identified a novel class of inhibitors of the checkpoint kinase Wee1, which have potential for use in cancer chemotherapy. These inhibitors are based on a 4-phenylpyrrolo[3,4-c]carbazole-1,3(2H,6H)-dione template and have been shown by X-ray crystallography to bind at the ATP site of the enzyme. An extensive study of the… (More)
A thyroid hormone receptor beta subtype-selective thyromimetic 5 was found to be efficacious in both mouse and monkey hair growth models after topical applications. It penetrates the skin according to the test in human cadaver skin mounted onto Franz diffusion chambers. The serum drug level of 5 is below the limit of quantification during tests in the bald… (More)
To characterize growth effects of epidermal growth factor (EGF) in subconfluent quiescent porcine aortic vascular smooth muscle cells (VSMC), we measured DNA and protein synthesis by [3H]thymidine (Thd) and [35S]methionine (Met) incorporation, respectively, and cell proliferation rates over 0-6 days in Dulbecco's modified Eagle's-Ham's F-12 media containing… (More)
A novel nonsteroidal androgen receptor antagonist, (R)-4-(1-benzyl-4,4-dimethyl-2-oxopyrrolidin-3-yloxy)-2-(trifluoromethyl)benzonitrile (1), for the topical control of sebum production is reported. This compound, which is potent, selective, and efficacious in the clinically validated golden Syrian hamster ear animal model, was designed to be delivered to… (More)
A series of diphenyl ethers was prepared and evaluated for androgen receptor antagonist activity in human androgen receptor binding and cellular functional assays. Analogs with potent in vitro activities were evaluated for topical in vivo efficacy in the Golden Syrian Hamster ear model. Several compounds showed reduction in wax esters in this validated… (More)
The first examples of thioether-substituted benzonitriles as potential soft-drug androgen receptor antagonists are reported. A number of 4-(alkylthio)- and of 4-(arylthio)-benzonitrile analogs were evaluated in human androgen receptor binding and cellular functional assays. Analogs with potent in vitro binding and cellular activities were evaluated for… (More)
Synthesis, pharmacology, and pharmacokinetic profiles of (1R, 2S)-4-(2-cyano-cyclohexyl-oxy)-2-trifluoromethyl-benzonitrile are reported. This compound demonstrated remarkable potency for stimulating hair growth in a male C3H mouse model as well as reducing sebum production in the male Syrian hamster ear model.
A series of substituted 4-aryl-2-trifluoromethylbenzonitrile analogs were evaluated in the human androgen receptor binding and cellular functional assays. Analogs with sufficient in vitro binding and cellular potency (IC(50)<200 nM) were tested in the progesterone receptor binding assay for selectivity and in the Golden Syrian hamster ear model for in vivo… (More)
A practical Buchwald-Hartwig amination of 2-bromopyridines with volatile amines is developed in sealed tubes. The method provides an expedient entry to a variety of secondary and tertiary aminopyridines that are otherwise not readily synthesized.
