[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.
比活度为84.2居里/毫摩尔的[3H]CP - 96.345已通过高温固态同位素交换由CP - 96.345制备而成。该氚标记化合物在抑制碘化P物质与各种物种的脑膜结合方面与母体拮抗剂具有同等效力。使用豚鼠脑富含纹状体的膜通过放射性配体分析检测到了[3H]CP - 96.345的直接结合。
