Cancer is one of the leading causes of death worldwide. Although several potential therapeutic agents have been developed to efficiently treat cancer, some side effects can occur simultaneously. Papaverine, a non-narcotic opium alkaloid, is a potential anticancer drug that showed selective antitumor activity in various tumor cells. Recent studies have demonstrated that metal complexes improve the biological activity of the parent bioactive ligands. Based on those facts, herein we describe the synthesis of novel papaverine–vanadium(III), ruthenium(III) and gold(III) metal complexes aiming at enhancing the biological activity of papaverine drug. The structures of the synthesized complexes were characterized by various spectroscopic methods (IR, UV–Vis, NMR, TGA, XRD, SEM). The anticancer activity of synthesized metal complexes was evaluated in vitro against two types of cancer cell lines: human breast cancer MCF-7 cells and hepatocellular carcinoma HepG-2 cells. The results revealed that papaverine-Au(III) complex, among the synthesized complexes, possess potential antimicrobial and anticancer activities. Interestingly, the anticancer activity of papaverine–Au(III) complex against the examined cancer cell lines was higher than that of the papaverine alone, which indicates that Au-metal complexation improved the anticancer activity of the parent drug. Additionally, the Au complex showed anticancer activity against the breast cancer MCF-7 cells better than that of cisplatin. The biocompatibility experiments showed that Au complex is less toxic than the papaverine drug alone with IC50 ≈ 111 µg/mL. These results indicate that papaverine–Au(III) complex is a promising anticancer complex-drug which would make it a suitable candidate for further in vivo investigations.

A series of 2-arylidene-N-(quinolin-6-yl)hydrazine-1-carboxamides 5a–5o were synthesized and characterized. The synthesized compounds (5a–5o) were screened in vitro against three breast cancer cell lines: SKBR3, MDA-MB-231, and MCF-7 cancer cell lines by the MTT assay. According to MTT results, compounds 5k and 5l showed better antiproliferative activities over MCF-7 cell lines with IC50 values of 8.50 and 12.51 μM. Colony formation assay indicated 5k/5l treatment obviously inhibited the growth of MCF-7 cells and 5k/5l-induced cell cycle was arrested in the G2-M phase. Moreover, 5k/5l significantly increased the level of cleaved PARP and induced the apoptosis in MCF-7 cells. In addition, compared to Hela cells, MCF-7 cells were more sensitive to 5k/5l treatment.

Abstract Background and objectives: Breast cancer presents high morbidity among women with various treatment challenges. This study aims to evaluate the repurposed lamotrigine schiff base metal (LTG-SB-M) coordinates against in-vitro MCF-7 breast cancer cell lines and in-vivo N-methylnitrosourea (NMU)-persuaded toxicity of rats’ mammary gland. Method: In-silico computational analysis and in vitro cytotoxic studies on MCF-7 breast cancer cell lines was executed to build up the assumptions. In-vivo NMU-induced anticancer potential was assessed in forty Wistar rats; assigned into five groups of 8 rats each. Group I served as normal control and received normal saline, Group II received NMU (50 mg/kg), Group III received tamoxifen, whereas; Group IV and V received LTG-SB-M derivative (LAC3, LBC3) at dose of 100 mg/kg body weight, for 15 consecutive days. Intraperitoneal injection of NMU (single dose) was given at the age of 5, 9 and 13 weeks to the rats with the three week interval. For all experimental animals; biochemical markers were assessed. DNA strand breakage alongside the hormonal profile of estrogen and progesterone was also estimated. Results: All tested compounds present significant activity against MCF-7 cell lines in vitro and NMU-induced mammary tumor in vivo. The in vivo results of tested compounds present a significant decrease in weight of organ; with reinstated renal and hepatic enzymes. Histological analysis revealed strong countenance of proteins, estrogen, and progesterone in NMU-treated rats. Conclusion: These results suggest that LTG-SB-M complex can be used as better anticancer agent against breast cancer.

Aims: Development of 1-[(1R, 2S)-2-fluorocyclopropyl]ciprofloxacin-1,2,4-triazole-5(4H)- thione hybrids as potential dual-acting mechanism anticancer agent to overcome the drug resistance. Background: Chemotherapy is an essential tool for the treatment of lung and female breast cancers, and numerous anticancer agents have been launched for this purpose. However, the clinical outcomes of chemotherapy are usually far from satisfactory due to the side effects and resistance to chemotherapeutic drugs. Thus, it is urgent to develop novel anti-lung and anti-breast cancer agents. Background: Chemotherapy is an essential tool for the treatment of lung and female breast cancers, and numerous anticancer agents have been launched for this purpose. However, the clinical outcomes of chemotherapy are usually far from satisfactory due to the side effects and resistance to chemotherapeutic drugs. Thus, it is urgent to develop novel anti-lung and anti-breast cancer agents. Objective: The primary objective of this study was to evaluate the potential of bis-isatin scaffolds with alkyl/ether linkers between the two isatin moieties against different human breast cancer cell lines including A549, MCF-7 and their drug-resistant counterparts A549/CDDP, MCF-7/ADM cells. Methods: The 1-[(1R, 2S)-2-fluorocyclopropyl]ciprofloxacin-(4-methyl/phenyl/benzyl-3-aryl)-1,2,4- triazole-5(4H)-thione hybrids were screened for their in vitro activity against drug-sensitive lung (A549), breast (MCF-7) and their drug-resistant counterparts A549/CDDP (cisplatin-resistant), MCF- 7/ADM (doxorubicin-resistant) cancer cell lines by MTT assay. The inhibitory activity of these hybrids against topoisomerase II and EGFR was also evaluated to investigate the potential mechanism of action of these hybrids. Result: The most prominent hybrid 7k (IC50: 37.28-49.05 µM) was comparable to Vorinostat against A549 and A549/CDDP lung cancer cells, and was 2.79-2.94 times more active than Vorinostat against MCF-7 and MCF-7/ADM breast cancer cell lines. Moreover, hybrid 7k (IC50: 8.6 and 16.4 µM) also demonstrated dual inhibition against topoisomerase II and EGFR. Conclusion: The 1-[(1R, 2S)-2-fluorocyclopropyl]ciprofloxacin-1,2,4-triazole-5(4H)-thione hybrids possess equally activity against both drug-sensitive cancer cells and their drug-resistant counterparts, and the majority of them were no inferior to the reference Vorinostat. The mechanistic study revealed that these hybrids could inhibit both topoisomerase II and EGFR, so these hybrids can be developed as dual-acting mechanism anticancer agents.

Nowadays, hybrid drugs have gained a significant role in the treatment of different health problems. Most of the hybrid molecules with different heterocyclic moieties were proved to be potent anti-tumor agents in cancer chemotherapy. Hence, the present study is aimed at the evaluation of in vitro anticancer activity of novel hybrid molecules (pyrazolyl benzoxazole conjugates) and to investigate their anticancer activity by molecular docking studies. Designed, synthesized and characterized the novel pyrazolyl benzoxazole conjugates. Anticancer activity of these compounds was determined by SRB assay. Then molecular docking studies were carried out against proto-oncogene tyrosine-protein kinase (ATP-Src, PDB: 2BDF), a putative target for cancer. All the synthesized compound derivatives were evaluated against MCF-7, KB, Hop62 and A549 cancer cell lines. Compounds 9b and 9c exhibited excellent anticancer activities with GI50 values of <0.1 µM against MCF-7 and A549 cell lines. Compound 9e exhibited good antitumor activity on MCF-7 and A-549 with GI50 values of 0.12 µM and 0.19 µM respectively. Compound 9g showed better anticancer activity on A-549 cancer cell line with GI50 of 0.34 µM. The two-hybrid molecules 9b and 9c are found to be comparably potent with the standard drug doxorubicin and may act as drug lead compounds in medicinal chemistry aspect. The present docking investigation proved that having benzoxazole of compound 9c at the position of benzofuran of reference compound (N-acetyl pyrazoline derivative) might be valid for contributing to anti-cancer activity.
