Substance P-related peptide that inhibits binding of G proteins to their receptors. Competitively and reversibly inhibits M2 muscarinic receptor activation of Gi or Go and inhibits Gs activation by β-adrenoceptors.
MA-2029 is selective for the motilin receptor over various other receptors and ion channels. MA-2029 is a selective and competitive motilin receptor antagonist (IC50=4.9 nM). MA-2029 may be useful for gastrointestinal disorders associated with disturbed g
SRX246 has no interaction at V1b and V2 receptors. SRX246 shows negligible binding at 64 other receptors classes, including 35 G-proteincoupled receptors. SRX246 is a potent and CNS-penetrant vasopressin 1a (V1a) receptor antagonist (Ki=0.3 nM for human V
