|Abstract:||The specific binding of [125I]ET-1 to rat cardiac membrane fragments was inhibited by [D-Arg1,D-Phe, D-Try7,9,Leu11] substance P [substance P(D)], a potent bombesin antagonist. This inhibitory effect required high concentrations (greater than 3X10(-6)M) of substance P(D) and was accompanied by a steep increase in non-specific binding, and not a decrease in total binding. Such results indicate that substance P(D) does not competitively inhibit the specific binding of [125I]ET-1 to rat cardiac membrane fragments.|
