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.

Abstract Background Melittin, a peptide component of honey bee venom, is an appealing candidate for cancer therapy. In the current study, melittin, melittin-loaded niosome, and empty niosome had been optimized and the anticancer effect assessed in vitro on 4T1 and SKBR3 breast cell lines and in vivo on BALB/C inbred mice. "Thin-layer hydration method" was used for preparing the niosomes; different niosomal formulations of melittin were prepared and characterized in terms of morphology, size, polydispersity index, encapsulation efficiency, release kinetics, and stability. A niosome was formulated and loaded with melittin as a promising drug carrier system for chemotherapy of the breast cancer cells. Hemolysis, apoptosis, cell cytotoxicity, invasion and migration of selected concentrations of melittin, and melittin-loaded niosome were evaluated on 4T1 and SKBR3 cells using hemolytic activity assay, flow cytometry, MTT assay, soft agar colony assay, and wound healing assay. Real-time PCR was used to determine the gene expression. 40 BALB/c inbred mice were used; then, the histopathology, P53 immunohistochemical assay and estimate of renal and liver enzyme activity for all groups had been done. Results This study showed melittin-loaded niosome is an excellent substitute in breast cancer treatment due to enhanced targeting, encapsulation efficiency, PDI, and release rate and shows a high anticancer effect on cell lines. The melittin-loaded niosome affects the genes expression by studied cells were higher than other samples; down-regulates the expression of Bcl2, MMP2, and MMP9 genes while they up-regulate the expression of Bax, Caspase3 and Caspase9 genes. They have also enhanced the apoptosis rate and inhibited cell migration, invasion in both cell lines compared to the melittin samples. Results of histopathology showed reduce mitosis index, invasion and pleomorphism in melittin-loaded niosome. Renal and hepatic biomarker activity did not significantly differ in melittin-loaded niosome and melittin compared to healthy control. In immunohistochemistry, P53 expression did not show a significant change in all groups. Conclusions Our study successfully declares that melittin-loaded niosome had more anti-cancer effects than free melittin. This project has demonstrated that niosomes are suitable vesicle carriers for melittin, compare to the free form.

First Results

Arsonoliposomes (ARSL) constitute a particular class of liposomes that incorporate arsonolipids (ARS) into their membranes. ARSL realize selective toxicity to cancer cells; thus, they are an important tool in the treatment of cancer. Folic acid (FA) is widely used in targeted drug delivery due to its high affinity for the folate receptors that are overexpressed in cancer cell membranes. The aim of our studies was to develop novel triple-negative breast cancer (TNBC)-targeted ARSL by incorporating folic acid-conjugated polyethylene-glycol PEG-lipid (FA-PEG-lipid) into their membrane and loading them with anticancer drug doxorubicin (DOX). ARSL incorporating 0.1 mol% of FA-PEG-lipid were prepared and loaded with DOX, using the active loading protocol. They were characterized for their size distribution, zeta potential and drug entrapment efficiency (%). Their cytotoxic activity towards TNBC cell lines, particularly MDA-MB-231 (epithelial human breast cancer cells) and MCF7 (human breast cancer cells), was evaluated by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT-assay. The first results demonstrated enhanced toxicity of this novel type of ARSL towards cancer cells, which is particularly interesting and deserves further exploitation.

Previous studies reported some associations between class A antibodies specific for benzo[a]pyrene (IgA-Bp), estradiol (IgA-Es) and progesterone (IgA-Pg) and breast cancer (BC) in women like as with lung cancer (LC) in men. It was suggested that IgA-Bp and IgA-Es may stimulate tumor initiation and promotion, whereas IgA-Pg may inhibit the in vivo human carcinogenesis.The purpose of this study was to identify the suggested associations of such immunological imbalance with BC and LC in postmenopausal women.The serum A-class antibodies specific to benzo[a]pyrene, estradiol and progesterone (IgA-Bp, IgA-Es, IgA- Pg) were studied in 335 healthy women, 824 breast cancer (BC) patients and 127 cases of lung cancer (LC) by means of non-competitive solid phase immunoassay. The following results were obtained: Increased ratio of IgA-Bp and IgA-Es amounts exceeding the IgA-Pg levels was associated with a higher risk of breast cancer (OR = 2.8 and 2.4 respectively, p < 0.0001), and higher risk of LC (OR = 2.9 and 2.8, respectively, p < 0.0001). Conversely, the OR values decreased to 0.3-0.4 for BC and LC if IgA-Pg levels were higher than IgA-Bp and IgA-Es levels (p < 0.0001). These findings confirm the hypothesis that IgA-Bp and IgA-Es are capable to stimulate, and IgA-Pg, to inhibit the BC and LC occurrence n postmenopausal women. The balance between IgA-Bp and IgA-Es, on the one hand, and IgA-Pg, on the other hand, is much more important than individual contents of these antibodies.In conclusion, the phenomenon of “immunological interference” is revealed, i.e., the mutual enhancement of IgA-Bp and IgA-Es effects, thus, probably, stimulating the initial and subsequent events of carcinogenesis initiation and promotion, with a weak anticancer effect of IgA-Pg, and by weakening the mutual procarcinogenic effects of IgA-Bp and IgA-Es by the marked effect of IgA-Pg.
