A sulfonoglycolipid with Na+,K+-ATPase inhibitory activity, produced by a cultured unique diatom symbiont isolated from a larger foraminifera.
A unique diatom (Entomoneis sp.) was isolated from a larger foraminifera (Marginopora vertebralis) and was successfully mass cultured. 6-Sulfo-O-alpha-D-quinovopyranosyldiacylglycerol was isolated from this diatom as an Na+,K+-ATPase inhibitor.
