  Synthesis of an analogue of the substance P C-terminal hexapeptide with modification at the glutaminyl and methioninyl residues and increased activity in NK-2 receptor type: Structure-activity relationships

  摘要：

  Analogues of [Orn6]-Sp6-11 have been synthesized in which the Met11 residue is replaced by Hse(CH3), Hse(Bzl), Nva(5-OCH3), Nva(5-OBzl) and Abu. These analogues were tested in 3 in vitro preparations representative of NK-1, NK-2 and NK-3 receptor types. The Hse(Bzl) analogue is 16.6-fold more potent than the parent hexapeptide at the NK-2 receptor and 2.4-fold more potent at the NK-3 receptor. The Nva(5-OCH3) analogues howed weak antagonist activity in NK-2 and NK-3 receptor types, being a full agonist at NK-1. It is concluded from structure-activity correlations that the role of Met11 side chain in substance P is associated with activity and/or efficacy, as appropriate modifications in the side chain may result either in agonists with increased activity compared to the parent hexapeptide or selective agonists or may induce antagonism.

  N-Adamantane-substituted tetrapeptide amides and the pharmacologically acceptable salts thereof are disclosed herein. These compounds are analogs of enkephalin wherein the methionine or leucine of position 5 has been substituted by an adamantyl amide and the glycine of position 2 has been substituted by various amino acid residues. Optionally the tyrosine of position 1 and the phenylalanine of position 4 may be substituted by various amino acid residues. These compounds exhibit agonist activity at opiate receptor sites and are useful as analgesics.

  We describe herein the syntheses and evaluation of a series of C-termini pyridyl containing Phe*-Ala-based BACE inhibitors (5-19). In conjunction with four fixed residues at the P1 (Phe), P1' (Ala), P2' (Val), and P2' cap (Pyr.), rather detailed SAR modifications at P2 and P3 positions were pursued. The promising inhibitors emerging from this SAR investigation, 12 and 17 demonstrated very good enzyme potency (IC50 = 45 nM) and cellular activity (IC50 = 0.4 muM). (C) 2003 Elsevier Ltd.

  Potent and selective non-thiol-containing inhibitors of protein farnesyltransferase are described. FTI-276 (1) was transformed into pyridyl ether analogue 19. The potency of pyridyl ether 19 was improved by modification of the biphenyl core to that of an o-tolyl substituted biphenyl core to give 29. In addition to 0.4 nM in vitro potency, 29 displayed 350 nM potency in whole cells as the parent carboxylic acid. The o-tolyl biphenyl core dramatically and unexpectedly enhanced the potency of other compounds as exemplified by 46, 47, 48, and 49.
