Background: Breast cancer is most frequently diagnosed cancer globally but there is not any ideal economical and safer agent that not only decreases the progression but also resolve complexities associated with breast cancer such as inflammatory conditions. There was strong link between inflammation and cancer specially breast cancer. Thus by inhibiting the COX enzyme may inhibit the progression of cancer beside of its role in inflammatory conditions of breast. Study Design: Interventional In Vitro trial. Setting: Department of Pharmacology in alliance with PCMD. Period: The duration of study from April 2016 to February 2017. Methodology: For this purpose we used five cancerous lines MCF-7, MDA-MB-231, MCF-10, HT-29 and Hela cell lines. For demonstrating the cytotoxic effects of Apricoxib we used MTT assay (for all cell Lines) and Trypan blue dye exclusion assay (Primarily for MCF-7 cell lines). For calculation of minimum dose required for exert cytotoxic effects of Apricoxib and its selectivitytowards cancerous cells of breast tissue we calculated its IC50 value and Selectivity Index (SI) by MTT assay. Results: Apricoxib significantly reduce the viability of MCF-7, MDA-MB-231, Hela, HT-29 as assessed by MTT assay in dose dependent manner (χ2 (2) = 26.483, p<0.001), (χ2 (2) = 26.49, p<0.001), (χ2 (2) = 26.062, p<0.001) and (χ2 (2) = 26.062, p<0.001) respectively. However Apricoxib had non-significant effects on % viability of MCF-10 cell line (χ2 (2) = 4.167, p=0.654) as assessed by MTT assay. Furthermore Apricoxib had lowest IC50 value against MCF-7 cell line. Conclusion: This study demonstrated that beside of primarily anti-inflammatory effects Apricoxib have additional benefits in term of exerting the cytotoxic effects (in vitro) on cancerous cell lines as indicated by reducing the % viability and reducing the Absorbance value of test sample as compare to control. This opens the newer path for researcher to evaluate different aspects of Apricoxib in field of chemotherapy.

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.

A bottom-up approach for synthesizing silver nanoparticles (AgNPs-GA) phytomediated by Garcinia atroviridis leaf extract is described. Under optimized conditions, the AgNPs-GA were synthesized at a concentration of 0.1 M silver salt and 10% (w/v) leaf extract, 1:4 mixing ratio of reactants, pH 3, temperature 32 °C and 72 h reaction time. The AgNPs-GA were characterized by various analytical techniques and their size was determined to be 5–30 nm. FTIR spectroscopy indicates the role of phenolic functional groups in the reduction of silver ions into AgNPs-GA and in supporting their subsequent stability. The UV-Visible spectrum showed an absorption peak at 450 nm which reflects the surface plasmon resonance (SPR) of AgNPs-GA and further supports the stability of these biosynthesized nanoparticles. SEM, TEM and XRD diffractogram analyses indicate that AgNPs-GA were spherical and face-centered-cubic in shape. This study also describes the efficacy of biosynthesized AgNPs-GA as anti-proliferative agent against human breast cancer cell lines, MCF-7 and MCF-7/TAMR-1. Our findings indicate that AgNPs-GA possess significant anti-proliferative effects against both the MCF-7 and MCF-7/TAMR-1 cell lines, with inhibitory concentration at 50% (IC50 values) of 2.0 and 34.0 µg/mL, respectively, after 72 h of treatment. An induction of apoptosis was evidenced by flow cytometry using Annexin V-FITC and propidium iodide staining. Therefore, AgNPs-GA exhibited its anti-proliferative activity via apoptosis on MCF-7 and MCF-7/TAMR-1 breast cancer cells in vitro. Taken together, the leaf extract from Garcinia atroviridis was found to be highly capable of producing AgNPs-GA with favourable physicochemical and biological properties.

Cinchonine is a type of cinchona alkaloid compound commonly found and/or isolated from Cinchona sp. plant. It is commonly used to treat malaria, and can potentially be used against cancer cells. In this particular study, cinchonine ester derivatives were extracted through esterification processs. Synthesized esther is aimed to gain higher lipophilicity of cinchonine so that makes it easier to pass through cell membrane. Esterification was done using DCC activator as well as DMAP catalyst with tiglic acid used to create cinchonine tiglat. Subsequent cinchonine tiglat was obtained in the form of oil with 25,28% yield. The compound obtained from the synthesis was the analyzed using LC-ESI-MS and 1H-NMR spectroscopy instrumentation. Results show that the target compound has been successfully synthesized. Its cytotoxic ability against MCF-7 breast cancer cells was tested using the Alamar Blue method. Results concluded that cinchonine tiglat ester compound has a viable cytotoxic activity with IC50 value of 1.22 ppm.

Abstract The synthesis and anticancer evaluation of new series of nucleosides constructed on 5/6-azidoglycosyl or glucuronamide moieties and containing an O- or an N-dodecyl chain, respectively, are disclosed. Based on our previous results, their structures were planned to preclude them to act via a similar metabolic pathway than that of clinically used nucleoside antimetabolites, against which cancer cells frequently acquire resistance. Xylo and gluco-configured 5/6-azido-1,2-di-O-acetyl furanosyl and pyranosyl donors containing a 3-O-dodecyl group were synthesized from diacetone-d-glucose and were subsequently coupled with silylated uracil or 2-acetamido-6-chloropurine. N-Dodecyl glucuronamide-based nucleosides were accessed from acetonide-protected glucofuranurono-6,3-lactone, which was converted in few steps into O-benzylated 1,2-di-O-acetyl furanuronamide or pyranuronamide derivatives to undergo further N-glycosylation. Both types of nucleosides demonstrated notorious antiproliferative effects in chronic myeloid leukemia (K562) and in breast cancer (MCF-7) cells. The most potent molecules were a 6ʹ-azidoglucopyranosyl N7-linked purine nucleoside and glucofuranuronamide derivatives comprising N1-linked uracil and N7-linked purine units with activities in the single-digit micromolar order of concentration against both cell lines. Their GI50 values in MCF-7 cells were similar or ca. 3-fold lower than that of the standard drug 5-fluorouracil. Cell cycle studies and immunoblotting analysis of apoptosis-associated proteins in treated K562 cells indicated that the antiproliferative effect of the most effective nucleosides is based on apoptosis induction.
