摘要:
By employing a stereo simplification approach, a thorough SAR exploration of the piperidine region of Sch 206272 was possible through a practical and efficient synthesis of substituted cyclic ureas. This SAR study led to the identification of a benzimidazolinone series of compounds which display single digit nanomolar NK1/NK2 affinity and near micromolar binding for the NK3 receptor.
