Description

Bencyclane, a cycloheptane, is a vasodilator, antiplasmodic and a platelet aggregation inhibitor found to be effective in a variety of peripheral circulation disorders. Bencyclane has various other potentially useful pharmacological effects such as smooth muscle relaxation. Under the trade name Halidor it is used in several European countries to treat the symptoms of atherosclerosis, occlusive arterial disease. Its mechanism may involve block of calcium channels. However as was shown in vitro it does not act by a direct influence on the Ca2+ pumps of vascular smooth muscle cells. In in vitro biochemical assays related to smooth muscle excitation-contraction coupling, binding to beta 1-, beta 2-, and alpha-adrenergic receptors, inhibition of phosphodiesterase activity, and antagonism of calcium accumulation bencyclane bound to alpha- and beta-receptors. Bencyclane appeared to be a promising anti-sickling agent that can be used orally in sickle cell anaemia (SCD).

In Vitro Use Guide
At 10(-5) molar concentration bencyclane inhibited platelet adhesiveness and ADP or collagen induced platelet aggregation. 10(-5) M of bencyclane induced a slight swelling of platelets. At 10(-4) M it inhibited the formation of tentacles completely and transformed the platelets into small spheres when investigated with interference-phase contrast microscopy. It is likely that the morphologic changes induced by bencyclane are responsible for the inhibitory effect on the different platelet function tests in vitro.
