  Evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2-imines as inhibitors of nitric oxide synthase

  摘要：

  Syntheses and evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2-imines as inhibitors of nitric oxide synthase (NOS) are discussed. An extensive SAR was established for pyrrolidin-2-imines class of compounds. The amidines came out as the most potent inhibitors in addition to displaying selectivity. (C) 2004 Elsevier Ltd.

  We have developed a divergent strategy for the synthesis of five- and six-membered lactams via either an amidation of sp3 C-H bonds or electrophilic substitution of arenes via Ir-nitrene intermediates. With the employment of a readily available iridium catalyst in dichloromethane or hexafluoro-2-propanol, a wide range of lactams were synthesized in good to excellent yields with high selectivity.

  我们已经开发了一种通过sp3 CH键的酰胺化或Ir-nitrene中间体亲电取代芳烃来合成五元和六元内酰胺的策略。通过在二氯甲烷或六氟-2-丙醇中使用易于获得的铱催化剂，以高至优异的产率和高选择性合成了多种内酰胺。

  The present invention relates to ethynyl derivatives of formula I wherein R 1 is phenyl, which is optionally substituted by 1-2 halogen atoms; selected from fluorine or chlorine; or to a pharmaceutically acceptable acid addition salt in enantiomerically pure form. It has been found that the compounds of general formula I are allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5).

  本发明涉及式I的乙炔衍生物，其中R1为苯基，可以选择性地被1-2个卤原子取代；所述卤原子选择自氟或氯；或者为在对映纯形式下的药用可接受的酸盐。已经发现，一般式I的化合物是代谢型谷氨酸受体亚型5（mGluR5）的变构调节剂。

  The present invention relates to ethynyl derivatives of formula I wherein X is N or C-R, wherein R is hydrogen or halogen; G is N or CH; with the proviso that maximum one of G or X can be nitrogen; R1 is phenyl or pyridinyl, which are optionally substituted by halogen; R2 is hydrogen, lower alkyl, hydroxy, lower alkoxy or C(O)O-benzyl; R3,R3', R4, R4, R6, R6' are independently from each other hydrogen or lower alkyl; or R6 and R4 may form together with the carbon atom to which they are attached a C4-6-cycloalkyl ring, if m is 0 and n is 1 or 2; R5 is hydrogen or lower alkyl; n is 0, 1 or 2; m is 0 or 1; with the proviso that n and m are not simultaneously 0; or to a pharmaceutically acceptable acid addition salt, to a racemic mixture, or to its corresponding enantiomer and/or optical isomer and/or stereoisomer thereof. It has now surprisingly been found that the compounds of general formula I are positive allosteric modulators (PAM) of the metabotropic glutamate receptor subtype 5 (mGluR5). They may be used for the treatment of schizophrenia or cognitive disorders.
