been developed for the synthesis of symmetric and unsymmetric diarylsulfides at room temperature and in air. This methodology is reliable and offers a mild and easy to operate process for the synthesis of arylthioethers, which are essential compounds with applications in the pharmaceutical and agricultural industries. This method avoids the use of expensive transitionmetals, such as Pd, Ir or Rh,

The invention provides a newly discovered oxadiazole class of antibiotics. The oxadiazoles impair cell-wall biosynthesis and exhibit activities against the Gram-positive bacteria such as the bacterium Staphylococcus aureus, including methicillin-resistant S. aureus (MRSA) and vancomycin-resistant and linezolid-resistant S. aureus. For example, 5-(1H-indol-5-yl)-3-(4-(4-(trifluoromethyl)phenoxy)phenyl)-1,2,4-oxadiazole (antibiotic 75b) was efficacious in a mouse model of MRSA infection, exhibiting a long half-life, a high volume of distribution, and low clearance. Antibiotic 75b antibiotic is bactericidal and is orally bioavailable. This class of antibiotics can be used as a therapeutic agent against infections by Gram-positive bacteria such as MRSA.
Ni nanoparticles on RGO as reusable heterogeneous catalyst: effect of Ni particle size and intermediate composite structures in C–S cross-coupling reaction
The present work demonstrates the C-S cross-coupling reaction between aryl halides and thiols using nickel nanoparticles (Ni NPs) supported on reduced graphene oxide (Ni/RGO) as a heterogeneouscatalyst. It is observed that the uniformly dispersed Ni NPs supported on RGO could exhibit excellent catalytic activity in C-S cross-coupling reactions and the catalytic application is generalized with diverse

Inhibition of sodium-dependentglucose transporter 2 (SGLT2), the transporter that is responsible for renal re-uptake of glucose, leads to glucosuria in animals. SGLT-mediated glucosuria provides a mechanism to shed excess plasma glucose to ameliorate diabetes-related hyperglycemia and associated complications. The current study demonstrates that the proper relationship of a 4'-substituted benzyl group
