  摘要：

  合成了一系列的组胺H（3）受体拮抗剂thioperamide单取代的苄基类似物，并评估了它们对豚鼠空肠的组胺H（3）受体活性。在苄基部分的邻位引入Cl，Br和I导致pA（2）值增加，而对位的相同取代基导致pA（2）值降低。但是，氟取代基使pA（2）的位置大大降低。分子建模揭示了一个QSAR，其pA（2）与硫脲和苄基部分之间的二面角与所计算的取代碳原子上的电子密度之间具有相关性（r = 0.93）。为了验证该QSAR模型是否具有预测价值，对邻叔丁基和甲基类似物进行了合成和评估。

  A lead compound which had sub-micromolar affinity for the rabbit NK1 receptor but negligible affinity for rat NK1 receptors, 3a, was discovered by directed screening. 2-Substitution in the ring of the benzylthiourea substituent in the initial lead was found to be important, and halogens (Cl, Br) in this position were found to improve affinity for the human receptor. The activity of a series of 2-halo-substituted benzylthioureas was then optimized by modification of the proline diphenylmethyl amide, guided by a simple conceptual model based on structural overlay between these early antagonists and NK1 selective peptides. In this way, aromatic amino acid amides were identified which had improved affinity with respect to the starting diphenylmethyl (DPM) amides. The first sub-nanomolar ligand for the human NK1 receptor which arose from this series, 4af, combined a 2-chlorobenzylthiourea unit with a 2-naphthylalanine amide. Contemporaneously it was discovered that the benzylthiourea unit could be simplified to a phenylthiourea providing that an appropriate 2-substituent was also incorporated. Combination of these two series gave 2-NO2 phenylthiourea analogues which led directly to the analogous urea, 5f(2-nitrophenylcarbamoyl-(S)-prolyl-(S)-3-(2-naphthyl)alanyl-N-benzyl-N-methylamide, SDZ NKT 343), a highly potent ligand for the human NK1 receptor (K-i = 0.16 nM). In addition to its high in vitro potency, 5f proved to be a potent orally active analgesic in guinea pig models of chronic inflammatory and neuropathic pain. The nature of the 2-aryl substituent was found to be critical for oral activity in this series. Clinical evaluation of 5f as a novel analgesic agent is currently underway.
