NZ-105, a new 1,4-dihydropyridine derivative: correlation between dihydropyridine receptor binding and inhibition of calcium uptake in rabbit aorta.

The correlation between the binding of NZ-105, a newly synthesized 1,4-dihydropyridine (DHP) derivative, on DHP receptors and its inhibitory activity on transmembrane 45Ca2+ uptake was investigated. 3H-NZ-105 bound rabbit aortic microsomes more slowly than did 3H-nitrendipine (3H-NTD): the association and dissociation rate constants of 3H-NZ-105 were about 70 times and 10 times less than those ...

Dihydropyridine and Ryanodine Receptor Binding After

The purpose of this study was to determine if there are alterations in the dihydropyridine and/or ryanodine receptors that might explain the excitation-contraction uncoupling associated with eccentric contraction-induced skeletal muscle injury. The left anterior crural muscles (i.e., tibialis anterior, extensor digitorum longus, and extensor hallucis longus) of mice were injured in vivo by 150 ...

Dihydropyridine Calcium Channel Blockers

T he concept of proarrhythmia, the realization that antiarrhythmic drugs can occasionally drastically aggravate the very problem for which they were prescribed, is now widely appreciated and has undoubtedly lead to an overall improvement in the use of these drugs. Proarrhythmia is a particularly dangerous type of side effect: It is unpredictable, may easily escape detection, and can turn a beni...

Role of Calcium Permeation in Dihydropyridine Receptor Function

The skeletal and cardiac muscle dihydropyridine receptors (DHPRs) differ with respect to their rates of channel activation and in the means by which they control Ca2+ release from the sarcoplasmic reticulum (Adams, B.A., and K.G. Beam. 1990. FASEB J. 4:2809-2816). We have examined the functional properties of skeletal (SkEIIIK) and cardiac (CEIIIK) DHPRs in which a highly conserved glutamate re...

Correlation between increases in dihydropyridine binding in vivo and behavioural signs of ethanol withdrawal in mice.

Increased ligand binding to dihydropyridine receptors in the central nervous system after chronic ethanol consumption is thought to contribute to the withdrawal syndrome. Previous studies demonstrated such changes when the binding was measured in vitro, which, as the receptors are voltage-sensitive, may not accurately reflect the binding in vivo. In the present study, dihydropyridine binding wa...
