Synthesis and antiproliferative activities of diversely substituted glycosyl-isoindigo derivatives
摘要:
in the course of structure-activity relationship studies, diversely substituted 1-(beta-(D)-glucopyranosyl)-isoindigo derivatives were prepared from commercially available indolines. Their antiproliferative activities were evaluated toward a panel of human solid cancer cell lines (PC 3, DLD-1, MCF-7, M4Beu, A549, PA 1), a murine cell line (L929) and a human fibroblast primary culture to get an insight into the substitution pattern required for the best biological potencies.

An efficient and simple process for the preparation of stable nanocopper(0) on alumina [Cu(0)/Al2O3] from the inorganic composite precursor copperaluminumhydrotalcite (Cu‐Al HT) by a chemical reduction method is described. Cu(0)/Al2O3 was employed as an efficientcatalyst in the acceptor‐ and oxidant‐free dehydrogenation of various amines and alcohols to their corresponding dehydrogenated products

The synthesis, biological activity, and molecular modeling of a novel series of substituted1-(3-pyridylcarbamoyl)indolines are reported. These compounds are isosteres of the previously published indole urea 1 (SB-206553) and illustrate the use of aromatic disubstitution as a replacement for fused five-membered rings in the context of 5-HT2C/2B receptor antagonists. By targeting a region of space previously
Model studies on a synthetically facile series of N-substituted phenyl-N′-pyridin-3-yl ureas leading to 1-(3-pyridylcarbamoyl) indolines that are potent and selective 5-HT2C/2B receptor antagonists

antagonists have been prepared by rapid parallel synthesis. These N-substituted phenyl-N'-pyridin-3-yl ureas were found to have a range of 5-HT2C receptor affinities and selectivities over the closely related 5-HT2A receptor. Extrapolation of simple SAR, derived from this set of compounds, to the more active but synthetically more complex 1-(3-pyridylcarbamoyl)indoline series allowed us to target optimal
