Biochem/physiol Actions

DPPE is a potent, selective ligand of the microsomal anti-estrogen binding site. DPPE is a tamoxifen derivataive that binds with high affinity to the anti-estrogen binding site, but unlike tamoxifen, does not bind to the estrogen receptor. DPPE sensitizes MDR tumor cells to chemotherapy and also inhibits histamine binding at the intracellular histamine site.

In 5-day incubation of an estrogen receptor-negative human ovarian cancer cell line (KF) with N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine-HCl (DPPE), the concentration of DPPE required for 50% inhibition of KF cell proliferation (IC50) was 1.7 microM. The IC50 of DPPE for inhibition of protein

It has been reported that docetaxel is a P-glycoprotein substrate and is metabolized via the cytochrome P450 (CYP) 3A subfamily in rats. Tesmilifene is a substrate of the CYP3A subfamily and is an inhibitor of P-glycoprotein. Thus, the effects of

New compounds have been synthesized based on the structure of the anti-tumoral drug tamoxifen and its diphenylmethane derivative, N,N-diethyl-2-[(4-phenyl-methyl)-phenoxy]-ethanamine, HCl (DPPE). These new compounds have no affinity for the estrogen receptor (ER) and bind with various affinity to the anti-estrogen

Endogenous histamine regulates the haematopoiesis. Histidine decarboxylase inhibitor decreases the histamine level, and its intracellular antagonist decreases the histamine effect. The effect of histidine decarboxylase inhibitor (alpha-fluoromethyl histidine) and the intracellular antagonist of histamine [N'N-diethyl-2-4-(phenylmethyl) phenoxyethan-amine-HCl] was investigated on the

N,N-diethyl-2-[4-(phenylmethyl)phenoxy]ethanamine (DPPE; tesmilifene) is a novel agent that augments chemotherapy cytotoxicity in vitro and in vivo. A phase II trial combining DPPE and doxorubicin (DOX) in metastatic breast carcinoma showed increased response over that expected with DOX. We report a
