  Discovery of Potent Benzofuran-Derived Diapophytoene Desaturase (CrtN) Inhibitors with Enhanced Oral Bioavailability for the Treatment of Methicillin-Resistant Staphylococcus aureus (MRSA) Infections

  摘要：

  Blocking the staphyloxanthin biosynthesis process has emerged as a new promising antivirulence strategy. Previously, we first revealed that CrtN is a druggable target against infections caused by pigmented Staphylococcus aureus (S. aureus) and that naftifine was an effective CrtN inhibitor. Here, we identify a new type of benzofuran-derived CrtN inhibitor with submicromolar IC50 values that is based on the naftifine scaffold. The most potent analog, 5m, inhibits the pigment production of S. aureus Newman and three MRSA strains, with IC50 values of 0.38-5.45 nM, without any impact on the survival of four strains (up to 200 mu M). Notably, compound 5m (1 mu M) could significantly sensitize four strains to immune clearance and could effectively attenuate the virulence of three strains in vivo. Moreover, 5m was determined to be a weak antifungal reagent (MIC > 16 mu g/mL). Combined with good oral bioavailability (F = 42.2%) and excellent safety profiles, these data demonstrate that 5m may be a good candidate for the treatment of MRSA infections.

  The relative reactivities of nuclear-substituted diphenylmethanes, deoxybenzoins (X·C6H4·CH2Bz), and allylbenzenes towards atomic bromine at 80° have been determined by means of competitive reactions by use of allylbenzene, diphenylmethyl methyl ether, and p-bromoethylbenzene, respectively, as reference standard. The results show ρ-values of –0·93, –0·92, and –0·68 by the Hammett equation for the three

Here, we report the development of a radical fluorosulfonylation of alkenes/intramolecular arylation cascade for the construction of chromanes with sulfonyl fluoride groups attached. The radical 1,2-fluorosulfonyl arylation reactions proceed well in both endo and exo cyclization fashions, allowing for further variation of the distance between the chromane core
