A zinc oxide catalyzed solvent-free mechanochemical process has been developed for the rapid construction of C-S bonds by using a nucleophilic substitution reaction (SN2 mechanism) that involves a variety of thiols and phenacyl/ benzyl/alkyl bromides. Notable advantages of this method in-clude its broad substrate scope, clean reaction profile, safety, scalability, high product yields at ambient conditions, and the recyclability of the catalyst. Furthermore, the prepared compounds are valuable building blocks for the synthesis of various biologically active molecules.

On account of its poor prognosis and deficiency of therapeutic stratifications, triple negative breast cancer continues to form the causative platform of an incommensurate number of breast cancer deaths. Aiming at the development of potent anticancer agents as a continuum of our previous efforts, a novel series of 2-((benzimidazol-2-yl)thio)-1-arylethan-1-ones 5a–w was synthesized and evaluated for its anti-proliferative activity towards triple negative breast cancer (TNBC) MDA-MB-468 cells. Compound 5k was the most active analog against MDA-MB-468 (IC50 = 19.90 ± 1.37 μM), with 2.1-fold increased activity compared to 5-fluorouracil (IC50 = 41.26 ± 3.77 μM). Compound 5k was able to induce apoptosis in MDA-MB-468, as evidenced by the marked boosting in the percentage of florecsein isothiocyanate annexin V (Annexin V–FITC)-positive apoptotic cells (upper right (UR) + lower right (LR)) by 2.8-fold in comparison to control accompanied by significant increase in the proportion of cells at pre-G1 (the first gap phase) by 8.13-fold in the cell-cycle analysis. Moreover, a quantitative structure activity relationship (QSAR) model was established to investigate the structural requirements orchestrating the anti-proliferative activity. Finally, we established a theoretical kinetic study.

In order to develop a potent anti-tumor agent that can target both cancer stem cells and the bulk of tumor cells, a series of 2-((benzimidazol-2-yl)thio)-1-arylethan-1-ones 5a-o was synthesized. All compounds were evaluated for their anti-proliferative activity towards colon HT-29 cancer cell line. In addition, their inhibitory effect against cell surface expression of CD133, a potent cancer stem cells (CSCs) marker, in the same cells was evaluated by flow cytometry at 10 μM. Compound 5l emerged as the most active anti-proliferative analog against HT-29 (IC50 Combining double low line 18.83 ± 1.37 μM), that almost equipotent as 5-fluorouracil (IC50 Combining double low line 15.83 ± 1.63 μM) with 50.11 ± 4.05% inhibition effect on CD133 expression, suggested dual targeted effect. Also, compounds 5h, 5j, 5k and 5m-o inhibited the expression of CD133 with more than 50%. The SAR study pointed out the significance of substitution of the pendent phenyl group with lipophilic electron-donating groups or replacing it by 2-thienyl or 2-furyl groups.

New styryl sulfone compounds have been synthesized and evaluated for their anti-proliferative activity. Among the compounds synthesized, one compound (7k) has shown 51% tumor growth inhibition in mice implanted with HT-29 human carcinoma at 400 mg kg-1 orally.
