K. Shiomi et al., ANDRASTINS A-SIMILAR-TO-C, NEW-PROTEIN FARNESYLTRANSFERASE INHIBITORS, PRODUCED BY PENICILLIUM SP FO-3929, Tetrahedron letters, 37(8), 1996, pp. 1265-1268
New protein famesyltransferase inhibitors, andrastins A similar to C (
1 similar to 3) have been isolated from the cultured broth of Penicill
ium sp. FO-3929. The structure of 1 enriched by [1,2-C-13]acetate was
elucidated by INADEQUATE and C-13-C-13 spin decoupling experiments. Th
e structure of 2 and 3 were also elucidated by NMR experiments. Andras
tins had an ent-5 alpha-14 beta-androstane skeleton with keto-enol tau
tomerism.
