Background: Chemotherapy is one of the mainstays of cancer treatment, despite the serious side effects of the clinically available anticancer drugs. In recent years increasing attention has been directed towards novel agents with improved efficacy and selectivity. Compounds with chalcone backbone have been reported to possess various biological activities such as anticancer, antimicrobial, anti-inflammatory, analgesic, antioxidant, etc. It was reported that aminomethylation of hydroxy chalcones to the corresponding Mannich bases increased their cytotoxicity. In this context, our interest has been focused on the design and synthesis of the so-called multi-target molecules, containing two or more pharmacophore fragments. Methods: A series of Mannich bases were synthesized by the reaction between 6-[3-(3,4,5- trimethoxyphenyl)-2-propenoyl]-2(3Н)-benzoxazolone, formaldehyde, and a secondary amine. The structures of the compounds were confirmed by elemental analysis, IR and NMR spectra. The new Mannich bases were evaluated for their in vitro cytotoxicity against a panel of human tumor cell lines, including BV-173, SKW-3, K-562, HL-60, HD-MY-Z and MDA-MB-231. The effects of selected compounds on the cellular levels of glutathione (GSH) were determined. Results: The new compounds 4a-e exhibited concentration-dependent cytotoxic effects at micromolar concentrations in MTT-dye reduction assay against a panel of human tumor cell lines, similar to those of starting chalcone 3. The tested agents led to concentration - dependent depletion of cellular GSH levels, whereby the effects of the chalcone prototype 3 and its Mannich base-derivatives were comparable. Conclusion: The highest chemosensitivity to the tested compounds was observed in BV- 173followed by SKW-3 and HL-60 cell lines.

Anti Cancer

Signal transducer and activator of transcription 3 (STAT3) is a transcriptional regulator of a number of biological processes including cell differentiation, proliferation, survival, and angiogenesis, while cyclin-dependent kinases (CDKs) are a critical regulator of cell cycle progression. These proteins appear to play central roles in angiogenesis and cell survival and are widely implicated in tumor progression. In this study, we used the well-characterized US National Cancer Institute 60 (NCI60) human tumor cell lines to screen the in vitro anti-cancer activities of our novel small molecule derivatives (NSC765690 and NSC765599) of salicylanilide. Furthermore, we used the DTP-COMPARE algorithm and in silico drug target prediction to identify the potential molecular targets, and finally, we used molecular docking to assess the interaction between the compounds and prominent potential targets. We found that NSC765690 and NSC765599 exhibited an anti-proliferative effect against the 60 panels of NCI human cancer cell lines, and dose-dependent cytotoxic preference for NSCLC, melanoma, renal, and breast cancer cell lines. Protein–ligand interactions studies revealed that NSC765690 and NSC765599 were favored ligands for STAT3/CDK2/4/6. Moreover, cyclization of the salicylanilide core scaffold of NSC765690 mediated its higher anti-cancer activities and had greater potential to interact with STAT3/CDK2/4/6 than did NSC765599 with an open-ring structure. NSC765690 and NSC765599 met the required safety and criteria of a good drug candidate, and are thus worthy of further in-vitro and in-vivo investigations in tumor-bearing mice to assess their full therapeutic efficacy.
