Euplotes vannus

Guella, G. Pietra, F. (2001B) unpublished results on sesquitopmes from Euplotes vannus. 

Vannusal B Vannusal B, isolated from Euplotes vannus, was originally proposed to have the structure 25a.Subsequent synthetic and NMR studies have settled on 25b as its actual structure. ...

Two atypical triterpenes were isolated from cultures of the species Euplotes vannus collected in Indonesia. These cyclical derivatives of squalene have an irregular carbon skeleton previously unknown in Nature. The relative percentages for varmusals A and B vary with the strain grown, and it has been shown that these derivatives are absent from Dunaliella salina, which is symbiotic with Euplotes vannus. The definitive structures of varmusals A and B were deduced from intense spectroscopic and synthetic researches (Nicolaou, Zhang, and Ortiz, 2009 Nicolaou, Ortiz, and Zhang, 2009 Nicolaou et al., 2010a, 2010b).
