This research aimed to produce new 1-[(aryl)(3-amino-5-oxopyrazolidin-4-ylidene) methyl]-2-oxo-1,2-dihydroquinoline-3-carboxylic acid derivatives and check their anticancer effect against the breast cancer MCF-7 cell line. The 2-oxo-1,2-dihydroquinoline-3-carboxylic acid (4) compound was obtained by hydrolyzing ethyl 2-oxo-1,2-dihydroquinoline-3-carboxylate (2) with thiourea and anhydrous potassium carbonate ethanol, which was then treated with ethyl 3-substituted 2-cyanoacrylates (6) in the presence of triethylamine in diethyl formamide to give 1-[2-(ethoxy)carbonyl-2-cyano-1-arylvinyl]-2-oxo-1,2-dihydroquinoline-3-carboxylic (7a,d). Cyclization of compound 7 with hydrazine hydrate ethanol inferred the association of 1-[(aryl)(3 amino-5-oxopyrazolidin-4-ylidene)methyl-2-oxo-1,2-dihydroquinol-3-carboxylates (8a,d). Spectroscopic and micro-analytical techniques such as IR, NMR, and elemental analysis were used to validate the structure of the synthesized organic compounds. The anticancer effects of the synthesized compounds 7a–d and 8a–d were tested by using the MTT assay on the MCF-7 cell line. When compared to the reference compound Dox, the compounds 7b, 7c, 8a, 8b, and 8c demonstrated strong anticancer activity against the MCF-7 cell line. The anticancer effects of the synthesized compounds 7a–d and 8a–d were tested against the MCF-7 cell line, using MTT assay. The compounds 7b, 7c, 8a, 8b, and 8c showed significant anticancer activity compared to the reference compound Dox against the MCF-7 cell line.

Holamine and funtumine, steroidal alkaloids with strong and diverse pharmacological activities are commonly found in the Apocynaceae family of Holarrhena. The selective anti-proliferative and cell cycle arrest effects of holamine and funtumine on cancer cells have been previously reported. The present study evaluated the anti-proliferative mechanism of action of these two steroidal alkaloids on cancer cell lines (HT-29, MCF-7 and HeLa) by exploring the mitochondrial depolarization effects, reactive oxygen species (ROS) induction, apoptosis, F-actin perturbation, and inhibition of topoisomerase-I. The apoptosis-inducing effects of the compounds were studied by flow cytometry using the APOPercentageTM dye and Caspase-3/7 Glo assay kit. The two compounds showed a significantly greater cytotoxicity in cancer cells compared to non-cancer (normal) fibroblasts. The observed antiproliferative effects of the two alkaloids presumably are facilitated through the stimulation of apoptosis. The apoptotic effect was elicited through the modulation of mitochondrial function, elevated ROS production, and caspase-3/7 activation. Both compounds also induced F-actin disorganization and inhibited topoisomerase-I activity. Although holamine and funtumine appear to have translational potential for the development of novel anticancer agents, further mechanistic and molecular studies are recommended to fully understand their anticancer effects.

Abstract Background Ursolic acid (UA), a plant extract from traditional Chinese medicines as well as edible vegetables, exhibits a potent anticancer activity in various tumor cells. Annexin A1(AnxA1) is dysregulated and play a pivotal role in various tumor. However, the function of AnxA1 in breast cancer(BC) remains unclear. Methods Western blot, real-time quantitative polymerase chain reaction(qRT- PCR), transwell, wound healing and immunofluorescence were used to study the biological features of AnxA1 in breast cancer. The stemness of cancer cells was assessed by sphere formation assay. CCK-8 and flow cytometry assay were used to detect the effects of ursolic acid on the growth, proliferation and apoptosis of breast cancer cells in vitro. A nude mice xenograft model was employed in vivo. The potential mechanism by which Ursolic acid regulates the biological behaviors of breast cancer stem cells through AnxA1 via the wnt/β-catenin signaling pathway was tested by western blot, qRT- PCR and immunohistochemistry. Results AnxA1 was highly expressed in MDA-MB-231 cell line compared with MCF-7 cell line, Down-regulation of AnxA1 could reduce the mammosphere formation, inhibit EMT, decrease the ability of migration and invasion in MCF-7 and MDA-MB-231 cells. Ursolic acid can reduce the expression of AnxA1 and inhibit proliferation of breast cancer cells, stemness, EMT, migration and invasion, promote cell apoptosis of breast cancer cell. This studies suggest that the anticancer effects of AnxA1 knockdown and UA treatment may be realized by affecting the EMT process and the wnt/β-catenin signaling pathway. Conclusions This research suggest that AnxA1 knockdown enhanced the sensitivity of breast cancer cells to UA, the combination of UA treatment and AnxA1 knockdown possesses multiple anti-tumor activities against breast cancer, as it, in particular, inhibited the cancer stem cell and attenuated EMT. Therefore, it is emerging as a promising therapeutic strategy to inhibit breast cancer.

Abstract Background Silver is a transition metal that is known to be less toxic than platinum. However, only few studies have reported the anticancer effects of some silver complexes and their possibility as an alternative to platinum complex. This study investigated the anticancer effects of the silver thiosulfate complex (STS), [Ag(S2O3)2]3−, consisting of silver and sodium thiosulfate. Methods In vitro cytotoxic activity of STS was investigated comparatively in human cancer cell lines (K562 and MCF-7) and normal human cells (mesenchymal stem cells and mammary epithelial cells). For its anticancer effects, cell cycle, mode of cell death, morphological changes, and accumulation of intracellular ROS and GSH were evaluated in MCF-7 to provide mechanistic insights. Results STS showed a concentration-dependent cytotoxicity in MCF-7 cell, which was abolished by pretreatment with N-acetylcysteine, suggesting ROS accumulation by STS. Moreover, STS caused cell cycle arrest at the G1 phase, decrease in the GSH levels, and morphological changes in MCF-7. Direct measurement of ROS demonstrated the elevation of intracellular ROS accumulation in cancer cells treated with STS; however, neither cytotoxicity nor ROS accumulation was observed in normal human cells. Conclusion The results obtained here are the first evidence to show that STS exhibited an anticancer activity through ROS-induced mechanisms, and that its cytotoxicity is highly selective to cancer cells. The results of the present study warrant further investigation on the detailed mechanism of STS actions, as well as its in vivo effectiveness and safety for clinical application.
