Novel Staphyloxanthin Inhibitors with Improved Potency against Multidrug Resistant Staphylococcus aureus
摘要:
Diapophytoene desaturase (CrtN) is a potential novel target for intervening in the biosynthesis of the virulence factor staphyloxanthin. In this study, 38 1,4-benzodioxan-derived CrtN inhibitors were designed and synthesized to overwhelm the defects of leading compound 4a. Derivative 47 displayed superior pigment inhibitory activity, better hERG inhibitory properties and water solubility, and significantly sensitized MRSA strains to immune clearance in vitro. Notably, 47 displayed excellent efficacy against pigmented S. aureus Newman, Mu50 (vancomycin-intermediate MRSA, VISA), and NRS271 (linezolid-resistant MRSA, LRSA) comparable to that of linezolid and vancomycin in vivo.

Tuberculosis is an infectious disease caused by the bacterium Mycobacteriumtuberculosis (Mtb). Mtb protein tyrosine phosphatase B (mPTPB) is a virulencefactor required for Mtb survival in host macrophages. Consequently, mPTPB represents an exciting target for tuberculosis treatment. Here, we identified N-phenyl oxamic acid as a highly potent and selective monoacid-based phosphotyrosine mimetic for

In some aspects, the instant disclosure relates to methods of treating chronic graft versus host disease (cGVHD). In some embodiments, the method comprises administering to a subject in need thereof a EZH2 inhibitor, a Bcl6 inhibitor and/or BRD4 inhibitor. The present disclosure is based, at least in part, on the discovery that enhancer of zeste homolog 2 (EZH2) inhibitors, B-cell lymphoma 6 protein (Bcl6) inhibitors and/or bromodomain-containing protein 4 (BRD4) inhibitors can be used to treat chronic graft versus host disease (cGVHD).

anti-9-amino-6-(trifluoromethyl) benzonorbornene (19), were prepared and evaluated. The competitive inhibition displayed by the fully extended analogue 12 coupled with the uncompetitive kinetics exhibited by the folded isomer 13 supports previous findings that a fully extended side chain conformation is optimal for binding to the active site of PNMT. In addition, the fact that 12 displayed enhanced affinity as an
