The cell free culture filtrate of a Comamonas testosteroni associated with an Entomopathogenic nematode (EPN), Rhabditis (Oscheius) sp. exhibited promising antimicrobial activity. The ethyl acetate extract of the bacterial culture filtrate was purified by

Three previously undescribed diketomorpholine natural products, along with the known phenalenones, herqueinone and norherqueinone, were isolated from the mycoparasitic fungal strain G1071, which was identified as a Penicillium sp. in the section Sclerotiora. The structures were established by analyzing NMR data and mass spectrometry fragmentation patterns. The absolute configurations of deacetyl-javanicunine A, javanicunine C, and javanicunine D, were assigned by examining ECD spectra and Marfey's analysis. The structural diversity generated by this fungal strain was interesting, as only a few diketomorpholines (~17) have been reported from nature.

Natural products (NPs) are an important inspirational source for developing drugs and chemical probes. In 1999, the group of ōmura reported the constitutional elucidation of zelkovamycin. Although largely unrecognized so far, this NP displays structural s

We validate the improved resolution and sensitivity of the C3 Marfey's method, including an ability to resolve all Ile isomers, against an array of amino acids commonly encountered in natural products and by comparison to an existing Marfey's m
