Studies on calcium antagonists binding

Clinical pharmacology of calcium antagonists. Satellite symposium on calcium antagonists.

A new class of agents has been made available for the treatment of hypertension. These calcium antagonists have rapid bioavailability and dramatic antihypertensive effects through reduction of total peripheral resistance and the vascular resistance of the major target organs of the body. These changes are usually associated with unchanged cardiac output, preserved organ blood flows, maintained ...

Calcium antagonists High-affinity binding and inhibition of calcium transport in a clonal cell line.

PC12 cells, a clonal rat pheochromocytoma cell line, possess voltage-dependent calcium channels that bind the high affinity dihydropyridine calcium antagonist [3H]nitrendipine and other calcium channel blockers. The binding is temperature-dependent and saturable, and shows no cooperativity. The calcium antagonists inhibit potassium-induced 45Ca uptake into the cells with approximately the same ...

Spectroscopic Studies on Titanium Ion Binding to the Apolactoferrin

Titanium (Ti) is a relatively abundant element that has found growing applications in medical science and recently some of Ti compounds are introduced as anticancer drugs. In spite of very limited data which exist on the Ti metabolism, some proteins might be involved in the mechanism of action of Ti. Up to our knowledge, there is not any report in the literature concerning binding of Ti to apol...

Effects of L-type Calcium Channel Antagonists Verapamil and Diltiazem on fKv1.4ΔN Currents in Xenopus oocytes

The goal of this study was to determine the effects of the L-type calcium channel blockers verapamil and diltiazem on the currents of voltage-gated potassium channel (fKv1.4ΔN), an N-terminal-deleted mutant of the ferret Kv1.4 potassium channel. Measurements were made using a two electrode voltage clamp technique with channels expressed stably in Xenopus oocytes. The fKv1.4ΔN currents displayed...
