  Synthesis and neuroleptic activity of a series of 1-[1-(benzo-1,4-dioxan-2-ylmethyl)-4-piperidinyl]benzimidazolone derivatives

  摘要：

  A series of 1-[1-(benzo-1,4-dioxan-2-ylmethyl)-4-piperidinyl]benzimid azolones with various substituents in both aromatic rings have been synthesized and tested for neuroleptic activity (antiapomorphine effects and [3H]spiroperidol binding) as well as extrapyramidal effects (cataleptogenic effect). A strong dependence of activity on the 5-substituent in the benzimidazolone moiety could be demonstrated. Some compounds show a large split between the desired antiapomorphine and the undesired extrapyramidal effect. From these, 1-[1-(benzo-1,4-dioxan-2-ylmethyl)-4-piperidinyl]-5-chlor obenzimidazol-2-one hydrochloride (HR 723), 12, has been selected for further preclinical and toxicological profiling.

  Benzodiazepine calcitonin gene-related peptide (CGRP) receptor antagonists: Optimization of the 4-substituted piperidine

  摘要：

  In our continuing effort to identify CGRP receptor antagonists for the acute treatment of migraine, we have undertaken a study to evaluate alternative 4-substituted piperidines to the lead dihydroquinazolinone 1. In this regard, we have identified the piperidinyl-azabenzimidazolone and phenylimidazolinone structures which, when incorporated into the benzodiazepine core, afford potent CGRP receptor antagonists (e.g., 18 and 29). These studies produced a potent analog (18) which overcomes the instability issues associated with the lead structure 1. A general pharmacophore for the 4-substituted piperidine component of these CGRP receptor antagonists is also presented. (c) 2006 Elsevier Ltd. All rights reserved.

  摘要：

  本发明涉及某些新型化合物及其衍生物，它们的合成以及它们作为选择性α-1C肾上腺素受体拮抗剂的用途。这些化合物的一个应用是治疗良性前列腺增生。这些化合物在其选择性方面具有能够松弛富含α1C受体亚型的平滑肌组织的能力，同时不会引起直立性低血压。这样的组织之一是围绕尿道内膜的组织。因此，这些化合物的一个用途是为患有良性前列腺增生的男性提供急性缓解，使尿液流动更加顺畅。此外，这些化合物的另一个用途是与人类5α-还原酶抑制剂化合物相结合，从而实现对良性前列腺增生的急性和慢性缓解。

  A novel series of competitive, reversible cathepsin S (Cats) inhibitors was discovered and optimized. The 4-(2-keto-1-benzimidazolinyl)-piperidin-1-yl moiety was found to be an effective replacement for the 4-arylpiperazin-1-yl group found in our earlier series of Cats inhibitors. This replacement imparted improved PK properties as well as decreased off-target activity. Optimization of the ketobenzimidazole moiety led to the discovery of the lead compound JNJ 10329670, which represents a novel class of selective, noncovalent, reversible, and orally bioavailable inhibitors of cathepsin S.
