Introduction: Staphylococcus aureus remains one of the leading causes of morbidity and mortality worldwide. This is to a large extent due to antibiotic-resistant strains, in particular methicillin-resistant S. aureus (MRSA). While the toll of invasive MRSA infections appears to decrease in U.S. hospitals, the rate of community-associated MRSA infections remains constant and there is a surge of MRSA in many other countries, a situation that calls for continuing if not increased efforts to find novel strategies to combat MRSA infections.Areas covered: This review provides an overview of current investigational drugs and therapeutic antibodies against S. aureus in early clinical development (up to phase II clinical development). It includes a short description of the mechanism of action and a presentation of microbiological and clinical data.Expert opinion: Increased recent antibiotic development efforts and results from pathogenesis research have led to several new antibiotics and therapies, such as anti-virulence drugs, as well as a more informed selection of targets for vaccination efforts against MRSA. This developing portfolio of novel anti-staphylococcal drugs will hopefully provide us with additional and more efficient ways to combat MRSA infections in the near future and prevent us from running out of treatment options, even if new resistances arise.

Conversion of a wide range of N-Boc amides to aryl ketones was achieved with Grignard reagents via chemoselective C(O)-N bond cleavage. The reactions proceeded under catalyst-free conditions with different aryl, alkyl, and alkynyl Grignard reagents. alpha-Ketoamide was successfully converted to aryl diketones, while alpha,beta-unsaturated amide underwent 1,4-addition followed by C(O)-N bond cleavage to provide diaryl propiophenones. N-Boc amides displayed higher reactivity than Weinreb amides with Grignard reagents. A broad substrate scope, excellent yields, and quick conversion are important features of this methodology.

Synthetic Route of 497-25-6, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2.

We describe the synthesis and radical polymerization of series of styrenes with 2-oxazolidone moieties inherited from alpha-amino acids on the side chain. The 2-oxazolidone 2 was readily synthesized through the reaction of diphenyl carbonate with amino alcohols 1 that were prepared through the reduction of the corresponding alpha-amino acids (glycine, l-alanine, l-phenylalanine, l-valine, and l-methionine), in the presence of 1,8-diazabicyclo[5.4.0]-7-undecene as a base catalyst. The subsequent N-substitution reaction of 2-oxazolidone with 4-(chloromethyl) styrene in the presence of sodium hydride produced high yield of the corresponding styrenic compounds 3. Free radical polymerization of these monomers 3 smoothly proceeded in the quantitative monomer-conversion using benzoyl peroxide as a radical initiator to give the corresponding polymers (P3). The thermal properties of the resulting polymers were evaluated by differential scanning calorimetry and thermogravimetric analysis. These oxazolidone-containing polymers effectively adsorbed phenols from aqueous solution, and were also miscible with poly(4-vinylphenol) in the equimolar ratio mixture, because of the effective hydrogen bond interaction involving a carboxyl group of oxazolidone moieties and a hydroxyl group of the phenol.

Endowing rigid polyurethane foam (PUF) with a good fire-retardancy is essential for improving fire safety. Chemical improvement in fire-retardancy by using reactive-type flame retardants is better because of the disadvantages of traditional additive-type flame retardants. A reactive flame retardant tri-glycidyl phosphate (POG), which was synthesized by using phosphorus oxychloride and glycidol, was bound to the cross-linked network structure of PUF. The effects of POG on the physical-mechanical properties, morphology, thermal stability and fire-retardancy of PUF system were systematically investigated. Research results showed that POG resulted in an improvement in the thermal insulation ability and a slight decrease in the compressive strength of PUF. Furthermore, thermogravimetric analysis certified that the thermal stability and the char yield at 700 C of PUF were significantly enhanced by incorporating POG. The limiting oxygen index increased to 22.3% with rising loading of POG. Moreover, a 30.2% decline in total heat release was achieved, the time to flameout was significantly shortened. Additionally, the vertical burning test illustrated that POG effectively limited the spread of flame and eliminated melt dripping. Further study confirmed that the fire-retardancy of PUF was significantly improved by inhibiting flame in the gas phase and charring in condensed phase.

Three illustrative examples are presented from our own approaches to development of drug candidates based on structure-activity relationship analyses. Starting from a lead, 3-(S)-n-butyl-phthalide, an anticonvulsive principle, isolated from Chinese celery seeds, a number of congeners were synthesized and tested. Quantitative structure-activity relationship (QSAR) analyses revealed that the potency depends upon the configuration of substituents around the chiral center at the 3-position, in addition to the hydrophobicity and electronic structure of compounds, and the polarity of substituents in the aromatic moiety. RS-3-n-Butyl-6-amino-phthalide was selected as a candidate for antiepileptic drug. A series of modifications of an antipeptic-ulcer prototype, furazolidone, led to deduction of a lead skeleton. A series of related (hetero) aromatic aldehyde (thio) semicarbazones were synthesized and tested. The QSAR analyses showed that the activity is significantly dependent on the electron density of the (thio) carbonyl group, which is enhanced by the introduction of electrons-donating substituents. Hepatoprotective biphenyl compounds with structures simplified from that of an active principle of a Chinese traditional medicine, were investigated by the analysis of structural parameters obtained from their X-ray crystallography and UV spectrum. The structural requirements for activity were suggested from their configuration and conformation.
