    Opis:
    The novel mordent and disperse heterocyclic dyes were prepared by coupling of various diazo solution of aromatic amines with N-{4-[2-{3,5-bis(4-methoxyphenyl)-4,5-dihydro-pyrazol-1-yl}-2-oxoethoxy]phenyl}-1-(phenyldiazenyl)methanimine The resultant mordent and disperse heterocyclic dyes were characterized by elemental analyses, IR and NMR spectral studies. The UV-visible spectral data have also been discussed in terms of structural property relationship. All the disperse azo dyes were applied on polyester textile fibers. The percentage dye bath exhaustion and fixation on the polyester fibers have been found to be very good. Moderate to very good light fastness and washing fastness properties were indicated by the dyed fabrics. Structures of synthesized compounds were confirmed by physical and spectral analysis. The compounds are evaluated for their antimicrobial activities.

    Opis:
    About six (E)-2-(2-((aryl)(phenyl)methylene)hydrazinyl)benzo[d]thiazoles have been synthesized and characterized by literature data. The infra-red stretching frequencies (ν, cm-1) of NH, CN, C=C and the NMR chemical shifts (δ, ppm) of NH, C=N and ipso carbons were assigned. These spectroscopic data were correlated for studying the QSAR employing Hammett equation with various Hammett substituent constants, Swain-Lupton’s F and R parameters using single and multi-regression analysis. From the results of regression analysis, the QSAR will be predicted by means of effects of substituents on the spectroscopic data of the functional group frequencies. The molecular docking character was evaluated by Schrodinger program, probing analogue docking in Topoisomerase enzymes. The crystallographic enzyme ligand complex (PDB entry 3TTZ) was obtained from the RCSB Protein Data Bank.
