The tamoxifen [[metabolite]] and [[aromatase inhibitor]] [[norendoxifen]] is also a TPE derivative. In addition to their estrogenic activity, various TPE derivatives like tamoxifen and clomifene have been found to act as [[Protein kinase C#Inhibitors|protein kinase C inhibitor]]s.<ref name="pmid3458960">{{cite journal | vauthors = O'Brian CA, Liskamp RM, Solomon DH, Weinstein IB | title = Triphenylethylenes: a new class of protein kinase C inhibitors | journal = Journal of the National Cancer Institute | volume = 76 | issue = 6 | pages = 1243–1246 | date = June 1986 | pmid = 3458960 | doi = 10.1093/jnci/76.6.1243 }}</ref>
