Antianginal;Ca++ channel activator | [Uses]
Fendiline is an α2-adrenergic receptor antagonist (Kd = 2.6 μM) and an L-type calcium channel blocker (IC50 = 17 μM) well-known for its coronary vasodilator effects. Fendiline has recently been reported to inhibit K-Ras plasma membrane localization (IC50 = 9.64 μM), which prevents K-Ras signal transduction and blocks the proliferation of K-Ras-transformed tumor cells. | [Manufacturing Process]
21.13 grams of γ,γ-diphenyl-propylamine and 12.01 grams of acetophenone
are hydrogenated in 200 ml of methanol at 55°C and a pressure of 10
atmospheres in the presence of palladium charcoal. On filtration of the
catalyst the solution is concentrated and the remainder is distilled in vacuo at
a pressure of 0.3 Hg mm. The main distillate is collected at 206° to 210°C.
25.38 grams of N-[1'-phenylethyl-(1')]-1,1-diphenyl-propyl-(3)-amine are
obtained.
The product is dissolved in 134 ml of 96% ethanol whereupon 26.8 ml of
concentrated hydrochloric acid and 201 ml of water are added while cooling
with ice-water. The precipitate is filtered off and dried in vacuo at 100°C.
22.98 grams of N-[1'-phenylethyl)-(1')]-1,1-diphenyl-propyl-(3)-amine
hydrochloride are obtained. MP 200° to 201°C. On recrystallization from 285
ml of a 2:1 mixture of water and 96% ethanol the melting point remains
unchanged. | [Therapeutic Function]
Coronary vasodilator | [Biological Activity]
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]. | [storage]
