Bioassay studies of 2'-O-ethylmurrangatin isolated from a medicinal plant, Murraya paniculata

A secondary metabolite, 2'-O-ethylmurrangatin (1), was isolated from the leaves of a medicinal plant, Murraya paniculata. The structure of compound 1 was identified with the help of spectroscopic techniques. Compound 1 was screened for its antioxidant, lipoxygenase, prolyl endopeptidase, and respiratory burst inhibitory activities. 2'-O-Ethylmurrangatin (1) was found to have significant activity against lipoxygenase enzyme and moderate respiratory burst inhibitory activity, but no activity against either DPPH radical scavenging assay or prolyl endopeptidase enzyme.
