Abstract
Abstract
Modified nucleosides are the core precursors for the synthesis of artificial nucleic acids, and are important in the field of synthetic and medicinal chemistry. In order to synthesize various triazolo-compounds, copper and ruthenium catalysed azide–alkyne 1,3-dipolar cycloaddition reactions also known as click reaction have emerged as a facile and efficient tool due to its simplicity and convenient conditions. Introduction of a triazole ring in nucleosides enhances their therapeutic value and various photophysical properties. This review primarily focuses on the plethora of synthetic methodologies being employed to synthesize sugar modified triazolyl nucleosides, their therapeutic importance and various other applications.

Abstract
Newer non-ionic amphiphiles have been synthesized using biocompatible materials and by following a greener approach i.e., D-glucitol has been used as a template, and hydrophobic and hydrophilic segments were incorporated on it by using click chemistry. The hydrophilic segments in turn were prepared from glycerol using an immobilized Candida antarctica lipase (Novozym-435)-mediated chemoenzymatic approach. Surface tension measurements and dynamic light scattering studies reflect the self-assembling behavior of the synthesized amphiphilic architectures in the aqueous medium. The results from UV-Vis and fluorescence spectroscopy establish the encapsulation of guests in the hydrophobic core of self-assembled amphiphilic architectures. The results of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay indicate that the amphiphiles are well tolerated by the used A549 cell lines at all tested concentrations.

Abstract
A series of coumarin-tagged β-lactam triazole hybrids (10a-10o) were synthesized and tested for their cytotoxic activity against MDA-MB-231 (triple negative breast cancer), MCF-7 (estrogen receptor positive breast cancer (ER+)) and A549 (human lung carcinoma) cancer cell lines including one normal cell line, HEK-293 (human embryonic kidney). Two compounds 10b and 10d exhibited substantial cytotoxic effect against MCF-7 cancer cell lines with IC50 values of 53.55 and 58.62 μm, respectively. More importantly, compounds 10b and 10d were non-cytotoxic against HEK-293 cell lines. Structure-activity relationship (SAR) studies suggested that the nitro and chloro group at the C-3 position of phenyl ring are favorable for anticancer activity, particularly against MCF-7 cell lines. Furthermore, antimicrobial evaluation of these compounds revealed modest inhibition of examined pathogenic strains with compounds 10c and 10i being the most promising antimicrobial agents against Pseudomonas aeruginosa and Candida albicans, respectively.

Abstract
An efficient and scalable synthesis of new oligonucleotide monomers was developed for replacement of the phosphodiester backbone of RNA by a sulfonamide-containing backbone to enable construction of sulfonamide antisense oligonucleotides (SaASOs). It was shown that by employing these sulfonamide RNA (SaRNA) monomers, it was possible to synthesize oligomers in solution. The properties of a sulfonamide moiety replacement were evaluated by incorporation of a SaRNA-monomer into a DNA strand and performing thermal stability tests of the resulting DNA and RNA-double-strand hybrids. Although sulfonamide modification caused a decrease in melting temperature (Tm) of both hybrids, it was lower for the sulfonamide-containing DNA-RNA hybrid than that for the sulfonamide-containing DNA-DNA hybrid.

Abstract
Reactions of 1,4,5-triaryl-2-(4-bromomethyl)phenyl-imidazoles with sodium azide in acetone give the corresponding azidomethyl derivatives, which on 1,3-dipolar cycloaddition with various terminal alkynes in the presence of CuI afford novel 1,2,3-triazole products. On the other hand, treatment of 2,4,5-triaryl-1-(4-hydroxyphenyl)-imidazoles with propargyl chloride in the presence of a base gives the corresponding propargyl ether derivatives, which under CuI-catalyzed 1,3-dipolar cycloaddition with benzyl azide produce 1,2,3-triazole derivatives. All the products are characterized from their spectroscopic data and most are evaluated for fluorescence emission. The optical parameters of the studied products are also reported.

Abstract
A series of β-d-ribofuranosyl coumarinyl-1,2,3-triazoles have been synthesized by Cu-catalyzed cycloaddition reaction between azidosugar and 7-O-/7-alkynylated coumarins in 62-70% overall yields. The in vitro antimycobacterial activity evaluation of the synthesized triazolo-conjugates against Mycobacterium tuberculosis revealed that compounds were bactericidal in nature and some of them were found to be more active than one of the first line antimycobacterial drug ethambutol against sensitive reference strain H37Rv, and 7 to 420 times more active than all four first line antimycobacterial drugs (isoniazid, rifampicin, ethambutol and streptomycin) against multidrug resistant clinical isolate 591. Study of in silico pharmacokinetic profile indicated the drug like characters for the test molecules. Further, transmission electron microscopic experiments revealed that these compounds interfere with the constitution of bacterial cell wall possibly by targeting mycobacterial InhA and DNA gyrase enzymes. Study conducted on the activities of the test compounds on bacterial InhA and DNA gyrase revealed that the most bactericidal test compound, N1-(β-d-ribofuranosyl)-C4-(4-methylcoumarin-7-oxymethyl)-1,2,3-triazole (6b) and its corresponding directly linked conjugate N1-(β-d-ribofuranosyl)-C4-(4-methylcoumarin-7-yl)-1,2,3-triazole (11b) significantly inhibited the activity of both the enzymes. The results were further supported by molecular docking studies of the compound 6b and 11b with bacterial InhA and DNA gyrase B enzymes. Further, the cytotoxicity study of some of the better active compounds on THP-1 macrophage cell line using MTT assay showed that the synthesized compounds were non-cytotoxic.
