Sorocein I, a new Diels-Alder type adduct from Sorocea ilicifolia.
From ethyl acetate extract of the root bark of Sorocea ilicifolia a new ketalized Diels-Alder type adduct, sorocein I (1), was isolated.
Three New Diels-Alder Type Adducts from the Roots of Sorocea bonplandii Baillon
Three new ketalized Diels-Alder type adducts named soroceal (1), sorocein A (2), sorocein B (3), were isolated from the methanolic extract of the roots of Sorocea bonplandii. The structures were assigned on the basis of chemical and spectroscopic evidences
Inhibition of sterol and fatty acid biosyntheses by cerulenin in cell-free systems of yeast.
amide6>7). Cerulenin was found to cause a curling of the mycelium of filamentous fungi such as Trichophyton and Microsporiurns~1Q). The action mechanism of cerulenin has been investigated with Candida stellatoidea (C. stellatoidea) and Saccharomyces cerevisiae (S. cerevisiae)ll). In the previous experiments using the whole cells of C. stellatoidea, it has been observed to inhibit neither the biosyntheses of nucleic acids, protein, and cell wall, nor the exogenous
