  Substituent Effects of N-(1,3-Diphenyl-1H-pyrazol-5-yl)benzamides on Positive Allosteric Modulation of the Metabotropic Glutamate-5 Receptor in Rat Cortical Astrocytes

  摘要：

  CDPPB [3-cyano-N-(1,3-diphenyl-1H-pyrazol-5-yl) benzamide] was recently described as the first centrally active, positive allosteric modulator of rat and human metabotropic glutamate receptor (mGluR) mGluR(5) subtype. We explored the structural requirements for potentiation of glutamate-induced calcium release in naturally expressed mGluR5 in cultured rat astrocytes and increasing affinity for the allosteric antagonist binding site by evaluating 50 analogues of CDPPB. In the fluorometric calcium assay, CDPPB exhibited an EC50 value of 77 +/- 15 nM in potentiating mGluR(5)-mediated responses in cortical astrocytes and a K-i value of 3760 ( 430 nM in displacing [H-3] methoxyPEPy binding in membranes of cultured HEK-293 cells expressing rat mGluR5. The structure-activity relationships showed that electronegative aromatic substituents in the para-position of the benzamide moiety of CDPPB increase potency. Both binding and functional activities were further increased with a halogen atom in the ortho-position of the 1-phenyl ring. These effects of substitution do not match those of either aromatic ring of MPEP [2-methyl-6-(phenylethynyl)-pyridine] for the antagonist allosteric binding site. Combination of the optimal substituents and aromatic positions resulted in 4-nitro-N-(1-(2-fluorophenyl)-3-phenyl-1H-pyrazol-5-yl) benzamide (VU-1545) showing K-i) 156 (29 nM and EC50) 9.6 (1.9 nM in the binding and functional assays, respectively.

  A convenient one-pot synthesis of 4-amino-3-arylpyrazoles from α-phthaloylaminoacetophenones

  摘要：

  Condensation of alpha-phthaloylaminoacetophenones 1a-c with N,N-dimethylformamide dimethyl acetal afforded the novel enamines 3a-c. Cyclization of 3 with hydrazine, alkylhydrazine or phenylhydrazine salts (4a-d) gave 4-phthaloylamino-3-arylpyrazoles 7-9 in high yields. Deprotection of 7-9 was accomplished with hydrazine to provide 4-amino-3-arylpyrazoles 5 in good yields. (C) 1998 Elsevier Science Ltd. All rights reserved.

  A series of novel 3,4-disubstituted pyrazoles were synthesized. The cytotoxicity against U87MG glioma cell line have been investigated in vitro and three of these compounds showed promising inhibitory activity on cell growth with an IC(50) lower than 90 mu M. AutoDock molecular docking into type I TGF-beta receptor (TGF-beta-RI; PDB: 1py5) has been done for lead optimization of the mentioned compounds as potential TGF-beta-RI1 inhibitors. In particular, 3-aryl-4-amido pyrazole containing long omega-amino-aliphatic chain emerged as a good candidate for further optimization. Entrapment into targetable PEG-based micelles improved growth inhibition IC(50) values up to 100 nM and this could lead to a novel drug delivery strategy for treating glioblastoma.
