Structure of malhamensilipin A, an inhibitor of protein tyrosine kinase, from the cultured chrysophyte Poterioochromonas malhamensis.
A new chlorosulfolipid, malhamensilpin A [1] was isolated from the cultured chrysophyte Poterioochromonas malhamensis. Malhamensilipin A was demonstrated to be a modest inhibitor of pp60v-src protein tyrosine kinase. The structure was determined by detailed spectral analysis to be a novel C24 hexachloro lipid containing a vinyl sulfate ester (2,11,12,13,15,16-hexachloro-14-hydroxy-n-tetracos-1E-enol-1-sulfa te).
