title: [Preparation and characteristics of a tritiated derivative of CP-96,345--a nonpeptide antagonist of the substance P receptor with a high specific radioactivity].
abstract: [3H]CP-96.345 with the specific radioactivity of 84.2 Ci/mmol has been prepared from CP-96.345 by the high-temperature solid state isotopic exchange. The tritiated compound was equipotent with the parent antagonist in inhibiting the iodinated substance P binding to brain membranes from various species. Direct binding of [3H]CP-96.345 was detected by radioligand analysis using the striatum-enriched membranes from the guinea-pig brain.
