Abstract
The phorbol-related diterpene ester resiniferatoxin is at least 100-fold more inflammatory for the mouse ear than is the potent tumor promoter phorbol 12-myristate 13-acetate, but is nonpromoting. Resiniferatoxin is 100- to 1000-fold less active than is phorbol 12-myristate 13-acetate in in vitro assays with chicken and mouse fibroblasts. Resiniferatoxin and phorbol 12-myristate 13-acetate may have different primary target sites (receptors) and the fibroblast target may be homologous to that involved in promotion.
