Attenuation of Mycobacterium species through direct and macrophage mediated pathway by unsymmetrical diaryl urea
摘要:
Tuberculosis is a major threat for mankind and the emergence of resistance strain of Mycobacterium tuberculosis (Mtb) against first line antibiotics makes it lethal for human civilization. In this study, we have synthesized different diaryl urea derivatives targeting the inhibition of mycolic acid biosynthesis. Among the 39 synthesized molecules, compounds 46, 57, 58 and 86 showed MIC values <= 10 mu g/ml against H37Rv and mc(2)6030 strains. The best molecule with a methyl at ortho position of the first aromatic ring and prenyl group at the meta position of the second aromatic ring showed the MIC value of 5.2 mu g/ml and mu g/ml against H37Rv and mc(2)6030 respectively, with mammalian cytotoxicity of 163.4 mu g/ml. The effective compounds showed selective inhibitory effect on mycolic acid (epoxy mycolate) biosynthesis in C-14-radiolabelled assay. At the same time these molecules also executed their potent immunomodulatory activity by up-regulation of IFN-gamma and IL-12 and down-regulation of IL-10. (C) 2016 Elsevier Masson SAS.

This disclosure relates to compounds, pharmaceutical compositions comprising them, and methods of using the compounds and compositions for treating diseases related to Heat Shock Transcription Factor 1 (HSF1) activity and/or function. More particularly, this disclosure relates to methods of inhibiting HSF1 activity with these compounds and pharmaceutical compositions thereof, and methods of treating diseases associated with HSF1 activity and/or function, such as cancer.
Compounds of Formula I are provided. In which the variables are as described herein. Such compounds may be used to modulate CB1 activity in vivo or in vitro, and are particularly useful in the treatment of conditions responsive to CB1 modulation in humans, domesticated companion animals and livestock animals, including appetite disorders, obesity and addictive disorders. Pharmaceutical compositions and methods for using them to treat such disorders are provided, as are methods for using such ligands for receptor localization studies and various in vitro assays.
