The design of retinoid phospholipid prodrugs is described based on molecular dynamics simulations and cytotoxicity studies of synthetic retinoid esters. The prodrugs are degradable by secretory phospholipase A(2) IIA and have potential in liposomal drug delivery targeting tumors. We have

Six new compounds, including five new seco-abietane diterpenoids, 12-deoxy-seco-hinokiol methyl ester (1), 12-deoxy-11,12-dihydro-seco-hinokiol methyl ester (2), callicarpic acid A (3), 9alpha-hydroxycallicarpic acid A (4), and callicarpic acid B (5), and a new phenylethanoid derivative, 4-hydroxyphenethyl tetradecanoate (6), have been isolated
Homologous dicarboxyl dendritic amphiphiles-RCONHC(CH(3))(CH(2)CH(2)COOH)(2), 4(n); and ROCONHC(CH(3))(CH(2)CH(2)COOH)(2), 5(n), where R=n-C(n)H(2)(n)(+1) and n=13-22 carbon atoms-were synthesized. Critical micelle concentrations (CMCs) in aqueous triethanolamine solutions and at pH 7.4 were measured along with hemolytic activity (effective concentrations, EC(10)) in phosphate-buffered saline (PBS).

Cholera toxin (CT) is an archetypal bacterial toxin that binds with a high affinity to the receptor ganglioside GM1 on the intestinal epithelial surface and that causes the severe watery diarrhea characteristic of the disease cholera. Blockage of the interaction

Natural product drug discovery efforts frequently utilize noncellular screening assays. Fatty acids are commonly found in natural product extracts, and some have been shown to interfere with noncellular assays. Several pure fatty acids were tested using a noncellular aromatase assay
