Fendiline or Sensit (N-(3,3-diphenylpropyl)-(1-phenylethyl)-amine), is a diphenylalkylamine blocker of L-type calcium channels. Fendiline is an anti-anginal agent for the treatment of coronary heart disease. Pharmaco-dynamically, it exerts the typical calcium as well as calmodulin antagonistic actions: inhibition of the transmembrane calcium current, smooth muscle relaxation, negative inotropism, cardioprotection, inhibition of calmodulin-activated myosin light-chain kinase and phosphodiesterase. Pharmacokinetics reveal slow onset of action and a long half-life. The anti-anginal and anti-ischaemic efficacy of fendiline has been proven in several placebo-controlled, double-blind trials. Fendiline is an FDA-approved, albeit now clinically obsolete. Additionally, fendiline is a specific inhibitor of K-Ras plasma membrane localization that also inhibits K-Ras signal output and blocks the proliferation of K-Ras-transformed tumor cells.
