Aim:
Tuberculosis is responsible for 9.6 million infections and 1.5 million deaths in 2015. The development of multidrug-resistant and extensively drug-resistant strains has impeded the development of effective antitubercular therapy. Results/methodology: The present manuscript describes the synthesis of a series of 4-aminoquinoline-ferrocenylchalcone conjugates via Cu-promoted Huisgen's azide-alkyne cycloaddition reaction and evaluation of their antitubercular activities against mc26230 strain of Mycobacterium tuberculosis. The conjugate 11j proved to be the most potent of the synthesized conjugates with a minimum inhibitory concentration (MIC99) value of 30 μM and proved to be noncytotoxic against HeLa cells.
Conclusion:
The synthesized conjugates can act as starting point for the development of new antitubercular agents. Synthesis and antitubercular evaluation of 1H-1,2,3-triazole-tethered 4-aminoquinoline-ferrocenylchalcone conjugates. [Formula: see text].

A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
