A new series of benzoquinoline-based heterocycles was synthesized utilizing the building block synthon, 2-((3-chlorobenzo[f]quinolin-2-yl)methylene)hydrazine-1-carbothioamide via the condensation of 3-chlorobenzo[f]quinoline-2-carbaldehyde with thiosemicarbazide. The titled thiosemicarbazone scaffold was conducted with some carbon-centered electrophilic reagents such as acetic...
2,2′-((1Z-1′Z) (1,3-diphenylpropane-1,3-diylidene) bis (azanylylidene)) dibenzoic acid (H2L) Schiff base ligand, derived from condensation reaction in a molar ratio 2:1 between anthranilic acid and dibenzoyl methane, respectively. Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes were obtained from 1:1 (ligand: metal salt) reaction. Elemental analyses...
Crystal violet (CV) synthetic dyes are well known in the dyeing industry for their mitotic and mutagenic poisoning. CV dye being a toxic organic dye is responsible for serious health issues as well as environmental damage. In this study, an inexpensive biosorbent (white clover: Trifolium repens) stem powder was tested for the adsorption of CV dye (cationic dye) from an aqueous...
A novel series of quinoline-linked rhodanine bearing 1,2,3-triazole analogs (10a-l) have been designed and prepared. All the novel hybrids were analyzed and characterized by spectroscopic performances like 1H-NMR, 13C-NMR, and HR-MS analysis. The anticancer efficiency of final molecules was screened for their in vitro activity against the diverse cancer cells lines like HeLa...
A three-component approach was conducted to adeptly prepare a new series of (Z)-bis(N-phenylthiazol-2(3H)-imines. The newly synthesized compounds were prepared by refluxing a ternary mixture of phenyl isothiocyanate, the suitable α-bromoketones, and alkane-linked diamines in ethanol. Reaction conditions were optimized by comparing the yield of the final product under various...
Thromboembolism because of coronavirus infection (COVID-19) resulted in increasing the number of sudden deaths after recovery. So, patients were switched to edoxaban tosylate monohydrate (EDTM) therapy after low molecular weight heparin to shorten the hospitalization period. In response to increase the demand for EDTM, we developed a home-made screen-printed electrode to...
