Biological Activity
Calcium Channel[1]
McN5691 (1 and 10 μM) prevents 60 mM KCl-induced contraction and calcium uptake and causes concentration-dependent relaxation (EC50=190 μM) of 30 mM KCl-contracted aortic rings. At or below 10 μM, McN5691 (McN-5691) has no effects on basal tone or calcium uptake (45Ca) in isolated rings of rabbit thoracic aorta. McN5691 causes complete high affinity inhibition (Kd=39.5 nM) of specific diltiazem binding to the benzothiazepine receptor on the voltage-sensitive calcium channel in skeletal muscle microsomal membranes. In contrast to diltiazem, McN5691 inhibits specific dihydropyridine receptor binding, but the effect is biphasic with high (Kd=4.7 nM) and low (Kd=919.8 nM) affinity components. McN5691 inhibits norepinephrine (NE)-induced contraction (10 μM) and calcium uptake (1 and 10 μM) and causes concentration-dependent relaxation (EC50=159 μM) of 1 μM NE-contracted rings of rabbit thoracic aorta[1].

Protocol
Dogs[2]
14C- McN5691 is administered by gavage to male and female beagle dogs (3 of each sex, weight 10.2-12.8 kg) as a single 6 mg/kg (as free base in corn oil) dose. Plasma samples are obtained for 24 hours after dosing. Urine and fecal samples are collected over a 7-day period. Each collected sample is assayed for total radioactivity and analyzed by TLC and HPLC.
Rats[3]
Studies are conducted in male SHR and control normotensive Wistar-Kyoto (WKY) rats. All animals are housed in constant temperature and environment facilities and given standard lab chow and water ad libitum. Four separate studies are conducted using conscious, age-matched animals:(a) SHR receiving McN5691 as a hydrochloride salt (McN5691) (n=8, body weight=361±7 g); (b) SHR receiving vehicle (VH) (n= 8, body
weight=381±5g); (C) WKY receiving McN5691(n=9, body weight=355±7 g); and (d) WKY receiving VH (n=6, body weight=342±7g). McN5691 or VH alone is administered i.v. (right jugular vein) as a 15 min continuous infusion for each dose. Each animal receives three doses of McN5691 (0.3, 1.0 and 3.0 mg/kg) in a cumulative fashion or VH infused at an equal rate (0.0408 mL/min).
