1-acyl-2-benzylpyrrolidines were discovered as potent and competitive dualorexinreceptorantagonists. Metabolic stability was improved to afford oral exposure, and aqueous solubility was increased by twentyfold, providing compounds suitable for preclinical evaluation. Compound 27 showed insurmountable antagonism at both orexin 1 and orexin 2 receptor subtypes and displayed a comparable sleep-promoting

complexed in a 1:1 ratio with Pd(OAc)2, enables Pd‐catalyzed cross‐couplings to be run using ≤1000 ppm of this pre‐catalyst. Applications to Suzuki–Miyaura reactions involving highly funtionalized reaction partners are demonstrated, all run using environmentally benign nanoreactors in water at ambient temperatures. Comparisons with existing state‐of‐the‐art ligands and catalysts are discussed herein.

This invention is generally directed to the use of Indazole Compounds for treating or preventing diseases associated with protein kinases, including tyrosine kinases, such as proliferative diseases, inflammatory diseases, abnormal angiogenesis and diseases related thereto, atherosclerosis, macular degeneration, diabetes, obesity, pain and others. The methods comprise the administration to a patient in need thereof of an effective amount of an indazole compound that inhibits, modulates or regulates tyrosine kinase signal transduction. Novel indazole compounds or pharmaceutically acceptable salt thereof are presented herein.

and nine of them exhibited Ki values below nanomolar concentrations. The best scores were always obtained when the 5-phenyl-2-thiophenyl core was attached to the triazole. The selectivity of these compounds towards the nicotinic α4β2 and serotoninergic 5HT3 receptors was assessed and their brain penetration was quantified by the preparation and in vivo evaluation of two [18F] radiolabelled derivatives
