c-Src kinase activity. 3,4-Dichlorophenyl tetrahydroindazolone derivative (15) inhibited the cell proliferation of HT-29 and SK-OV-3 cells by 62% and 58%, respectively. 2,3-Diphenylsubstituted tetrahydroindazolone derivatives, 19, 25, and 33, inhibited the cell proliferation of HT-29 cells by 65–72% at a concentration of 50 μM. In general, the tetrahydroindazolones showed modest inhibition of c-Src kinase

Abstract A series of phenyl substituted bi-1,3,4-oxadiazole derivatives were designed and synthesized; the effect of substituent on the photophysicalproperties and molecular electronic structures was fully studied by the combination of experimental techniques and theoretical calculations. Compared to parent compound without any substituent (BOXD), fluoro-substituent shows little effect on the absorption

1-acetyl-4-benzyl-2-(thiazol-2-yl)semicarbazide (13) showed that it lost asymmetry and adopted a configuration midway between the corresponding D- and L-amino acid derivatives. Evaluation of 3 in both mice (ip) and rats (po) showed that the compounds exhibited significant anticonvulsant activities but in most cases at levels lower than their amino acid counterparts. One of the semicarbazides, 13, displayed excellent

A Pd-catalyzed denitrogenative Hiyama coupling of arylhydrazines and aryl silanes is described under mild conditions. The newly developed catalytic system does not require the use of expensive silver- or copper-based stoichiometric oxidants to obtain diaryl derivatives with high selectivity and reactivity. The reported coupling reactions are very practical as they do not require the protection of inert gas or oxygen and are tolerant to many functional groups. (C) 2015 Elsevier Ltd. All rights reserved.
