Background:

Naftopidil-d₅is intended for use as an internal standard for the quantification of naftopidil by GC- or LC-MS. Naftopidil is an antagonist of α₁-adrenergic receptors (α₁-ARs; K_is = 3.7, 20, and 1.2 nM for α_1A-, α_1B-, and α_1D-ARs, respectively).¹It is selective for α₁-ARs over α₂-ARs (K_i= 1,793 nM).²Naftopidil inhibits norepinephrine-induced contractions in various blood vessels isolated from dog, rabbit, guinea pig, or rat with pA₂values ranging from 6.73 to 8.15.²It reduces prostatic pressure and mean blood pressure in anesthetized dogs when administered at doses of 100 or 1,000 ?g/kg.³Naftopidil also inhibits the growth of androgen-sensitive LNCaP cells and androgen-insensitive PC3 cancer cells with IC₅₀values of 22.2 and 33.2 ?M, respectively.⁴Formulations containing naftopidil have been used in the treatment of benign prostatic hyperplasia.
