Studies on hypolipidemic agents. II. 3-(4-Phenoxybenzoyl)-propionic acid derivatives

The Reaction of Alkyl Isocyanides and Benzylidene Meldrum's Acid Derivatives in the presence of Water: A One-Pot synthesis of 4-(Alkylamino)-3-Aryl-4-Oxobutanoic Acids

The reaction between alkyl isocyanides and substituted-benzylidene Meldrum's acid derivatives in the presence of water produces 4-(alkylamino)-3-aryl-4-oxobutanoic acids in good yields.

2-[(Carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic Acids Selectively Suppressed Proliferation of Neoplastic Human HeLa Cells. A SAR/QSAR Study

A series of twenty alkyl-, halo-, and methoxy-aryl-substituted 2-[(carboxymethyl)sulfanyl]-4-oxo-4-arylbutanoic acids were synthesized. The new compounds, called CSAB, suppressed proliferation of human cervix carcinoma, HeLa cells, in vitro in a concentration range of 0.644 to 29.48 microM/L. Two compounds exhibit antiproliferative activity in sub-micromolar concentrations. Five compounds act in low micromolar concentrations (<2 microM/L). The most active compounds exert lower cytotoxicity toward healthy human peripheral blood mononuclear cells (PBMC and PBMC+PHA) (selectivity indexes > 10). A strong structure-activity relationship, using estimated log P values and BCUT descriptors, was observed.
