  Disulfide linked pyrazole derivatives inhibit phagocytosis of opsonized blood cells

  摘要：

  Immune thrombocytopenia (ITP) is caused by production of an autoantibody to autologous platelets. ITP can be treated either by reducing platelet destruction or by increasing platelet production. Fc gamma receptor mediated phagocytosis of the opsonized blood cells is a well-accepted mechanism for the underlying pathogenesis of ITP and inhibition of this phagocytosis process with small molecules is a potential strategy for the development of drugs against ITP. A broad screen indicated that 4-methyl-1-phenyl-pyrazole derivative (1) could inhibit the phagocytosis of opsonized blood cells with weak potency. We reveal here the discovery of the polysulfide products, synthesis of various 1-phenyl-pyrazole derivatives, and the biological evaluation of pyrazole derivatives as inhibitors of phagocytosis for potential use as therapeutics for ITP. Substitution at C4 of the pyrazole moiety in the disulfide-bridged dimers influenced the potency in the increasing order of 10 congruent to 11 congruent to 16 < 19 < 20. A novel scaffold, 20 with an IC50 of 100 nM inhibiting opsonized blood cell phagocytosis was identified as a potential candidate for further studies. Confirmation of the disulfide bridge additionally provides clues for the non-thiol or non-disulfide bridge carrying ligands targeting ITP and other similar disorders. (C) 2013 Elsevier Ltd.

  Stable reaction products of mucochloric acid with aromatic and heterocyclic thiols were synthesized and characterized. Under basic conditions the reactions proceeded with the substitution of the chlorine atom(s) by arylthiogroup(s), while in an acidic medium the hydroxy group at C-5 was substituted. Different types of new sulfur-containing products of di- and trisubstitution on the basis of mucochloric acid were obtained. In one case a new acyclic product-di-p-tolyl-2,3-bis-(p-tolylthio)butanedithioate-was isolated. The structure of all synthesized compounds was confirmed by IR, H-1, and C-13 NMR spectroscopy; three compounds were characterized by single crystal X-ray diffraction.

  3-Methyl-1-phenylpyrazole-5-thiol (3a)and its p-nitro- (5) and p-fluorophenyl (8) derivatives were prepared as potential antimicrobial agents in relatively good yields. Compounds 3a and 8 showed good antibacterial activities against MRSA, S. aureus, S. epidermidis, E. faecalis, E. faecium, and S. pyogenes. Moreover, compound 3a also showed a synergistic effect with some aminoglycosides.
