Background:

Fendiline is an α2-adrenergic receptor antagonist and L-type calcium channel blocker [1,2].


The α2 adrenergic receptor is a G protein-coupled receptor (GPCR). Until now, three different α2-receptor subtypes have been identified: α2A, α2B, and α2C. The α2-adrenergic receptor exists in vascular prejunctional terminals and inhibits the release of norepinephrine in a form of negative feedback. The α2 adrenergic receptor agonists produce diverse responses, including analgesia, sedation, anxiolysis, and sympatholysis [3]. L-type calcium channels are responsible for the excitation-contraction coupling of skeletal, cardiac muscle, smooth, and for aldosterone secretion in endocrine cells of the adrenal cortex [4].


Fendiline inhibited the activity of L-type Ca2+ channel blocker with the IC50 value of 17 μM [1]. Fendiline inhibited the activity of α2-adrenergic receptor with the Kd of 2.6 μM [2]. Fendiline significantly reduced nanoclustering of K-Ras and redistributed K-Ras from the plasma membrane to the endoplasmic reticulum (ER), Golgi apparatus, endosomes, and cytosol. Fendiline significantly inhibited signaling downstream of constitutively active K-Ras and endogenous K-Ras signaling in cells transformed by oncogenic H-Ras. Fendiline blocked the proliferation of pancreatic, colon, lung, and endometrial cancer cell lines expressing oncogenic mutant K-Ras [5]. Fendiline inhibited K-Ras plasma membrane localization with an IC50 of 9.64 μM [5]. Fendiline is an anti-anginal agent for the treatment of coronary heart disease. The anti-anginal and anti-ischaemic efficacy of fendiline has been proven in several placebo-controlled, double-blind trials [6].
