Description
In Vitro
The inhibitory effect of FR 113680 on SP-induced guinea-pig ileum contraction is competitive and the pA2 value is 7.53[1].
FR 113680 has not effect on [3H]-SP binding to rat cerebral cortical membranes (NK1), [3H]-neurokinin A ([3H]-NKA) binding to rat duodenum smooth muscle membranes (NK2) and [3H]-eledoisin (Ele) binding to rat cerebral cortical membranes (NK3)[1].
