One of the helpful ways to improve the effectiveness of anticancer agents and weaken drug resistance is to use hybrid molecules. therefore, the current study intended to introduce 20 novel xanthine/chalcone hybrids 9–28 of promising anticancer activity. Compounds 10, 11, 13, 14, 16, 20 and 23 exhibited potent inhibition of cancer cells growth with IC50 ranging from 1.0 ± 0.1 to 3.5 ± 0.4 μM compared to doxorubicin with IC50 ranging from 0.90 ± 0.62 to 1.41 ± 0.58 μM and that compounds 11 and 16 were the best. To verify the mechanism of their anticancer activity, compounds 10, 11, 13, 14, 16, 20 and 23 were evaluated for their EGFR inhibitory effect. The study results revealed that compound 11 showed IC50 = 0.3 μM on the target enzyme which is more potent than staurosporine reference drug (IC50 = 0.4 μM). Accordingly, the apoptotic effect of the most potent compounds 11 was extensively investigated and showed a marked increase in Bax level up to 29 folds, and down-regulation in Bcl2 to 0.28 fold, in comparison to the control. Furthermore, the effect of compound 11 on Caspases 3 and 8 was evaluated and was found to increase their levels by 8 and 14 folds, respectively. Also, the effect of compound 11 on the cell cycle and its cytotoxic effect were examined. Moreover, a molecular docking study was adopted to confirm mechanism of action.

Herein we report design, synthesis, and anticancer activity of compounds 6a–h and 11a–j. Compounds 6a–f were designed based on 3-aminomethyl pyridine attached to different acetamide derivatives and in compounds 6g–h it was attached to coumarin moiety. Coumarin containing compounds 6g–h showed very poor anticancer activity against both A549 (Lungs cancer cell line), and MCF-7 (Breast cancer cell line) cell lines in MTT assay. Compounds 11a–j were designed as derivatives of 3-aminomethyl pyridine and 4-amino chalcones. A series of chalcone derivatives of 3-aminomethyl pyridine 11a–j have been synthesized and screened for their in vitro anticancer activity and DNA binding affinity. Most of the compounds showed very good antimitotic activity against A549 cell line as compared to fluorouracil. Compounds 11g and 11i were selected for DNA-binding studies as they showed excellent activity against cancer cell lines in MTT assay. CT-DNA binding affinity of compounds 11g and 11i have been investigated by UV based DNA titration and fluorescence emission study against DNA-EtBr complex. Interestingly, compound 11i has displayed excellent antiproliferative activity, with IC50 0.0067?±?0.0002?μm, against MCF-7 cell line. Compound 11i has been studied for its cytotoxicity using MTT, LDH, as well as EtBr/AO assay and was found to induce apoptosis in the cancerous cell line.

A group of novel nitric oxide (NO) donating chalcone derivatives was prepared by binding various amino chalcones with different NO donating moieties including; nitrate ester, oximes and furoxans. Most of the prepared compounds showed significant anti-inflammatory activity using carrageenan-induced rat paw edema method compared with indomethacin. The prepared compounds exhibited more protection than indomethacin in regard to gastric toxicity. Histopathological investigation confirmed the beneficial effects of the NO releasing compounds in reducing ulcer formation. The incorporation of the NO-donating group into the parent chalcone derivatives caused a moderate increase in the anti-inflammatory activity with a marked decrease in gastric ulcerations compared to their parent chalcone derivatives.
