As part of a search for new antidiabetic agents, 4-oxazolealkanoic acid derivatives (III) were synthesized and tested for hypoglycemic activity in mice. 4-Oxazoleacetic acids (IIIb) bearing a styryl or a suitable aliphatic hydrocarbon moiety at the 2-position showed potent activity. The synthesis and structure-activity relationships of these compounds are presented.

demonstrated high and selective 5-LO inhibitory activity in the in vitro assays, with IC50 values ranging from 0.08 microM in mouse macrophages to 0.8 microM in human peripheral monocytes to 1.2 microM in human whole blood. This activity was selective for 5-LO, as concentrations up to 15 microM in mouse macrophages did not affect prostaglandin formation. Oxazole 59 was the most activeinhibitor in the human
