Secondary metabolites from the sponge Tedania anhelans: Isolation and characterization of two novel pyrazole acids and other metabolites
Abstract
Chemical investigation of the methanol extract of the sponge Tedania anhelans yielded the two unusual heteroaromatic acids, pyrazole-3(5)-carboxylic acid (2) and 4-methylpyrazole-3(5)-carboxylic acid (3), which are reported for the first time as natural products. The other compounds isolated were p-hydroxybenzaldehyde, phenylacetamide, 3-phenylpropionic acid, 3-(p-hydroxyphenyl) propionic acid, 3-(p-methoxyphenyl) propionic acid beta -carboline (norharman) (1), and the four diketopiperazines pro-val, pro-leu, pro-phe, and pro-tyr
