Synthesis and <i>in vitro</i> anti-proliferative evaluation of naphthalimide–chalcone/pyrazoline conjugates as potential SERMs with computational validation
Twenty different triazoles were prepared to probe the anti-tubercular structureâactivity relationships (SAR) within the β-lactamâferroceneâtriazole conjugate family. The compounds have been synthesized by copper-catalyzed âclick chemistryâ. In vitro anti-tubercular activity was determined for each compound but the synthesized hybrids failed to inhibit Mycobacterium tuberculosis growth even at high doses. The manuscript assumes significance as this is the first report on the inclusion of ferrocene nucleus in the well established β-lactam family via triazole linkers with reputed physicochemical profiles.

Copper-promoted azide-alkyne cycloadditions were attempted to synthesize a series of variedly functionalized 1H-1,2,3-triazole-linked isatin-ferrocene, ferrocenylmethoxy-isatin and isatin-ferrocenyl-chalcone conjugates. The synthesized scaffolds were assayed for their inhibitory activity against T. vaginalis as well as several common normal human flora bacteria. The observed inhibitory activities against

Ferrocenylchalcone–uracil conjugates: synthesis and cytotoxic evaluation
with the aim of evaluating their in vitro anti-proliferative efficacy on human leukemia (CCRF-CEM) and human breast adenocarcinoma (MDA-MB-468) cell lines. Cytotoxicevaluation studies identified a number of synthesized conjugates that inhibited the proliferation of leukemia cancer cells by ~70% after 72 h. The selected synthesized conjugates were found to be significantly less cytotoxic against normal

1<i>H</i>-1,2,3-Triazole-Tethered Isatin–Ferrocene and Isatin–Ferrocenylchalcone Conjugates: Synthesis and in Vitro Antitubercular Evaluation
A Cu-mediated azide-alkyne cycloaddition protocol has been employed for the synthesis of 16 different triazoles to probe the antitubercular structure activity relationships within the isatin-ferrocene-triazole conjugate family. The antitubercular evaluation studies revealed a marked improvement in activity with the introduction of ferrocene nucleus among precursors N-alkylazido isatins with a prefernce for halogen (F, Cl) substituent at C-S position of isatin as well as propyl chain length as a spacer. The induction of a chalcone nucleus resulted in the enhanced antimycobacterial efficacy irrespective of the subtituent and alkyl chain length as evidenced by the isatin-ferrocenylchalcone hybrids. The described protocol is the first successful attempt of the amalgamation of ferrocene isatin nuclei tethered via a triazole linker.
