Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

A method has been developed for the in situ sulfidation of Pd/C under continuous flow. The approach provides a cheap, sustainable, and operationally convenient method for chemoselective conjugate reduction by continuous hydrogenation. High conversions and excellent selectivities were obtained for olefin reduction in alpha/beta-unsaturated carbonyl compounds in the presence of hydrogenatively sensitive functionalities. The methodology was analyzed with a green metric system to highlight the sustainability features of the process.

I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Benzimidazoquinazolines as new potent anti-TB chemotypes: Design, and evaluation published in 2020.0.

In search for new molecular entities as anti-TB agents, the benzimidazoquinazoline polyheterocyclic scaffold has been designed adopting the scaffold hopping strategy. Thirty-two compounds have been synthesized through an improved tandem decarboxylative nucleophilic addition cyclocondensation reaction of o-phenylenediamine with isatoic anhydride followed by further cyclocondensation of the intermediately formed 2-(o-aminoaryl) benzimidazole with trialkyl orthoformate/acetate. The resultant benzimidazoquinazolines were evaluated in vitro for anti-TB activity against M. tuberculosis H37Rv (ATCC27294 strain). Fourteen compounds exhibiting MIC values in the range of 0.4-6.25 mu g/mL were subjected to cell viability test against RAW 264.7 cell lines and were found to be non-toxic (< 30% inhibition at 50 mu g/mL). The active compounds were further evaluated against INH resistant Mtb strains. The most active compound 6x [MIC (H37Rv) of 0.4 mu g/mL] and the compound 6d [MIC (H37Rv) of 0.78 mu g/mL] were also found to be active against INH resistant Mtb strain with MIC values of 12.5 and 0.78 mu g/mL, respectively.

Nano-ferrite-supported Cu nanoparticles (Fe-dopamine-Cu NPs) catalyzed anti-Markovnikov-selective hydroboration of alkenes with B(2)pin(2) is reported under mild reaction conditions. This protocol can be applied to a broad range of substrates with high functional group compatibility. In addition, we demonstrated the use of Fe-dopamine-Cu NPs as a catalyst for the beta-borylation of alpha,beta-unsaturated ketones and ester, providing alkylboronate esters in up to 98% yield. Reuse of the magnetically recyclable catalyst resulted in no significant loss of activity in up to five reaction runs for both systems.

Two chiral polymers based on binaphthol(BINOL) were synthesized. The polymer can be used as a chiral inducer to coordinate with ZnEt2 to form a recoverable self-supporting catalyst, which could be used in the asymmetric catalytic reaction of alpha, beta-unsaturated ketones. The target products of high yield and good enantioselectivity(e.e. value up to 99%) can be obtained under mild conditions. The catalytic activity was not reduced significantly after 4 or 5 cycles of recovery of the recovered polymers.

Bacterial lipopolysaccharides (LPS) are important bio-medical structures, playing a major role in the interaction with human immune systems. Their core regions, containing multiple units ofl-glycero-d-mannoheptoses (l,d-heptose), are highly conserved structurally (withO3 andO7 glycosidic bonds), making them an epitope of high interest for the potential development of new antibiotics and vaccines. Research in this field has always been restricted by the limited availability of the parentl,d-heptose as well as its biochemical epimeric precursord-glycero-d-mannoheptose (d,d-heptose). This problem of availability has recently been solved by us, through a rapid and efficient practical synthesis ofl,d-manno-heptose peracetate demonstrated at scale. Herein we report an optimized, technically simple and versatile synthetic strategy for the differentiation of both thel-glyceroandd-glycero-d-mannoheptose scaffolds. Our approach is based on an orthoester methodology for the differentiation of all three positions of the sugar core using aO6,O7-tetraisopropyl disiloxyl (TIPDS) protecting group for the exocyclic positions. Furthermore, the regioselective opening toward 7-OH acceptors (6O-FTIPDS ethers) differentiates the exocyclic diol which has been demonstrated with a broader set of substrates and for bothmanno-heptoses for the first time.

We describe an efficient synthesis of 2,4-substituted pyrido[4,3-d]pyrimidin-5(6H)-ones, which involves the acid-promoted cyclization of cyano enamine 15 to afford 2,4-bis(methylthio)pyrido[4,3-d]pyrimidin-5(6H)-one 17 as a key intermediate. Selective displacement of the 4-methylthio group by a wide range of anilines followed by oxidation of the 2-methylthio group and subsequent substitution by amines enabled the synthesis of a variety of 2,4-disubstituted pyrido[4,3-djpyrimidin-5(6H)-ones.
