This paper discusses a structural optimization method that optimizes shape and topology based on the phase field method. The proposed method has the same functional capabilities as a structural optimization method based on the level set method incorporating perimeter control functions. The advantage of the method is the simplicity of computation, since(More)

Optimization of the lead 2a led to the identification of a novel diarylketoxime class of melanin-concentrating hormone 1 receptor (MCH-1R) antagonists. Our focus was directed toward improvement of hERG activity and metabolic stability. The representative derivative 4b showed potent and dose-dependent body weight reduction in diet-induced obese (DIO)(More)
A convergent and enantioselective route to the hNK-1 receptor antagonist (1) is described, which sets all six stereogenic centers with high diastereoselectivity and delivers 1 in only 11 steps and 23% overall yield. The process was enabled by the development of the enantioselective enzymatic reduction of 3-functionalized cyclopentenones and stereospecific(More)
