The invention relates to a new class of compounds, which are 1-phenylalcoxy-2-β-phenylethyl derivatives, as P-glycoprotein (P-GP) inhibitors. These compounds are useful in drug resistance events. They have been shown able to inhibit in a dose-dependent manner Glycoprotein-P (P-gp) activity in cell lines in which the expression of said glycoprotein is very high, like Caco-2 (human colon cancer) cells and MCF7/Adr (adriamycin-resistant human breast carcinoma) cells. The invention also relates to methods of production and the utilization of such compounds as medicaments useful in the treatment of states linked to the difficulty for some drugs to cross the blood-brain barrier (BBB) and generally within the context of the problems of drug resistance induced by chemotherapy agents.

and their 5-HT1A and 5-HT2 affinity was determined. It was shown that the benzotriazole moiety contributes to both the 5-HT1A and 5-HT2 receptor affinity. It was demonstrated in several behavioral models that 4-[3-(benzotriazol-1- yl)propyl]-1-(2-methoxyphenyl)piperazine (11) is a new, potent presynaptic and postsynaptic5-HT1Areceptorantagonist. However, it is not selective for 5-HT1A versus alpha

The present invention provides N-phenylpiperazine derivatives for use as multiple binders and/or antagonists of α1A adrenoceptors, α1D adrenoceptors and 5-HT1A serotonin receptors. These substances are candidates to prototypes for the treatment of benign prostate hyperplasia and lower urinary tract symptoms, and are useful in pharmaceutical compositions.
