Structure-activity investigations of analogues of the C15-C26 phorboxazoles segment
Wolbers,Hoffmann,Sasse
, p. 1808 - 1810 (1999)
A variety of analogues of phorboxazole C15-C26 segment have been prepared via three different reaction sequences. Structure activity investigations of the oxazole substitution pattern point to a pharmacophoric lead structure.
