Diastereoselective intramolecular aldol ring closures of threonine derivatives leading to densely functionalised pyroglutamates related to oxazolomycin

Intramolecular aldol reactions on oxazolidine templates derived from threonine may be used to generate libraries of densely functionalised pyroglutamates with a high level of diastereoselectivity; the oxazolidine precursors themselves are suitable for further direct manipulation by side chain alkylation, permitting rapid access to cyclised products with several points of chemical diversity. Although these systems may be considered to be structural mimics of the functionalised pyroglutamate portion of oxazolomycin, little antibacterial activity against S. aureus and E. coli was found. These systems may additionally have application as three-dimensional fragments for drug discovery and development.

A mixed anhydride approach to the preparation of sulfinate esters and allylic sulfones: Trimethylacetic p-toluenesulfinic anhydride

A reagent combination of toluenesulfinic acid and trimethylacetyl chloride affords a putative trimethylacetic p-toluenesulfinic anhydride. This reagent has been used to prepare a series of sulfinate esters from primary and secondary alcohols. In addition, the reagent was used to convert Baylis-Hillman substrates into allylic sulfones. Attempts to use the reagent to convert amines to sulfinamides were unsuccessful. In contrast, the use of 2-pyrrolidinone afforded N-p-toluenesulfinyl pyrrolidinone in 64% yield. The use of a chiral 4-benzy1-1,3-oxazolidinone or 4-benzyl-1,3-oxazolidine-2-thione led to the isolation of S-p-tolyl ptoluenethiosulfonate. (C) 2017 Elsevier Ltd. All rights reserved.

Development of Antibacterial Agents Active against Drug-resistant Bacterial Pathogens Based on Total Synthesis of Nucleoside Natural Products

Natural products are a rich source for drug development. However, some biologically relevant natural products possess rather large, complex or labile chemical structures compared to synthetic drugs, which limits chemical modification in a process pursuing a structure-activity relationship. Here we describe the rational simplification of the muraymycins and caprazamycins class of nucleoside natural products to address the issue associated with their molecular complexity. First, the systematic structure-activity relationship (SAR) study of the muraymycins using an Ugi four-component reaction was investigated. Our SAR study of the muraymycins suggests a probable mechanism for inhibition of the MraY. The predicted binding model would provide further direction towards the design of potent MraY inhibitors. Next, function-oriented synthesis (FOS) of caprazamycins was investigated. Based on the conformation-activity relationship study of a series of analogs 36-38, we designed the oxazolidine-containing uridine derivatives 41-44 by restricting the conformation of 36-38. As a result, the tert-butyl ester derivatives 43 were found to be the most active against a range of bacterial strains containing VRE with a similar potency to the parent natural products. These studies provide a novel strategy for the development of a new type of antibacterial agent effective against drug-resistant bacteria.

HENNA-ALUMINUM COMBINATION TANNAGE: A GREENER ALTERNATIVE TANNING SYSTEM

Development of cleaner technologies for leather manufacture is imperative for the sustenance of the tanning industry. In the present study, a combination tanning system based on a henna-aluminum tannage for the production of upper leathers as a cleaner alternative is presented. Extract from the leaves of widely distributed Lawsonia inerims (Henna) from Sudan has been evaluated for its tanning characteristics in a combination tanning system based on henna and aluminum sulfate. Aluminum-henna (Al-henna) leathers tanned using 2% Al(2)O(3); followed by 20% henna resulted in shrinkage temperature above 95 degrees C. The uptake of henna in henna-Al tanning system with henna (20%) followed by aluminum (2% Al(2)O(3)) has been found to be better than the tanning system of Al-henna. These leathers showed compact fibre structure, indicating that the tanning process did not bring about any major change or destruction on the fibre structure of the leathers. Surface colour values of henna-Al leathers resulted in darker shades with less red and more yellow components in the crust leathers. The combination tanning system provides significant reduction in the discharge of total dissolved solids in the wastewater. Henna-Al combination tanning system resulted in leathers with good organoleptic and strength properties. The work presented in this paper established the use of henna and aluminum combination tanning system as an effective alternative cleaner tanning methodology.

Transition metal complexes of a versatile polyalkoxy oxazolidine-based ligand derived from in situ cyclization

One-pot reaction between 8-hydroxyquinoline-2-carboxaldehyde (HQC) and tris(hydroxymethyl)amino-methane (TRIS) followed by in situ cyclization yielded an oxazolidine based ligand which produced four mononuclear complexes of Mn-II(1), Co-II(2), Ni-II(3), Zn-II(4), a tetranuclear iron (Fe-4(III))) complex (5) and a tri-nuclear cobalt (CoIICo2III complex (6). Magnetic studies show dominant antiferromagnetic interaction in tetranuclear iron (Fe-4(III)) complex 5 and presence of the slow relaxation of magnetisation in 6. The compounds were also studied for their antibacterial properties. The oxazolidine ligand (H3L2) of this study showed good antimicrobial activity not only against Gram-positive bacteria but against Gram-negative bacteria too.

Environmentally Friendly and Regioselective One-Pot Synthesis of Imines and Oxazolidines Serinol Derivatives and Their Use for Rubber Cross-Linking

High-yield regioselective synthesis of imines and oxazolidines derivatives of 2-amino-1,3-propandiol (serinol) was achieved by performing the reaction with aldehydes and ketones, in the absence of solvents and catalysts. Only imines were obtained when the carbonyl compound was aromatic and/or sterically hindered and when conjugated double bonds were formed. 1,3-Oxazolidines were specifically obtained with either aldehydes or ketones with limited steric hindrance. The green reaction conditions here adopted for the synthesis of these classes of derivatives are not due to the structural and functional peculiarity of the serinol as a reactant and can also be extended to lipophilic amines with the same good results in terms of yield and selectivity. A revision of the mechanism typically accepted in the presence of solvent and catalysis is proposed, and the quantum mechanics calculations applied to some derivatives are in good agreement with the proposed rationalizations of the selectivity observed. Serinol itself and the imine and oxazolidine derivatives were used, in place of guanidine, as accelerators in compounds based on diene rubbers and silica, suitable for application in tire treads with low environmental impact. Efficient sulfur-based cross-linking and composites with a low dissipation of energy were obtained. The oxazolidine and imine appear to act as protective groups of the serinol primary amine. This work paves the way for the selective synthesis of biosourced families of chemicals, which could be used for large-scale applications, such as the one in rubber compounds, replacing toxic oil-based chemicals.

Depletion of M. tuberculosis GlmU from Infected Murine Lungs Effects the Clearance of the Pathogen

M. tuberculosis N-acetyl-glucosamine-1-phosphate uridyltransferase (GlmU(Mtb)) is a bifunctional enzyme engaged in the synthesis of two metabolic intermediates N-acetylglucosamine-1-phosphate (GlcNAc-1-P) and UDP-GlcNAc, catalyzed by the C- and N-terminal domains respectively. UDP-GlcNAc is a key metabolite essential for the synthesis of peptidoglycan, disaccharide linker, arabinogalactan and mycothiols. While glmU(Mtb) was predicted to be an essential gene, till date the role of GlmU(Mtb) in modulating the in vitro growth of Mtb or its role in survival of pathogen ex vivo / in vivo have not been deciphered. Here we present the results of a comprehensive study dissecting the role of GlmU(Mtb) in arbitrating the survival of the pathogen both in vitro and in vivo. We find that absence of GlmU(Mtb) leads to extensive perturbation of bacterial morphology and substantial reduction in cell wall thickness under normoxic as well as hypoxic conditions. Complementation studies show that the acetyl-and uridyl-transferase activities of GlmU(Mtb) are independently essential for bacterial survival in vitro, and GlmU(Mtb) is also found to be essential for mycobacterial survival in THP-1 cells as well as in guinea pigs. Depletion of GlmU(Mtb) from infected murine lungs, four weeks post infection, led to significant reduction in the bacillary load. The administration of Oxa33, a novel oxazolidine derivative that specifically inhibits GlmU(Mtb), to infected mice resulted in significant decrease in the bacillary load. Thus our study establishes GlmU(Mtb) as a strong candidate for intervention measures against established tuberculosis infections.
