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.

Cannonball (Couroupita guianensis) is a tree belonging to the family Lecythidaceae. Various parts of the tree have been reported to contain oils, keto steroids, glycosides, couroupitine, indirubin, isatin, and phenolic substances. We report here the synthesis of silver nanoparticles (AgNPs) using cannonball leaves. Green synthesized nanoparticles have been characterized by UV-Vis spectroscopy, SEM, TEM, and FTIR. Cannonball leaf broth as a reducing agent converts silver ions to AgNPs in a rapid and ecofriendly manner. The UV-Vis spectra gave surface plasmon resonance peak at 434 nm. TEM image shows well-dispersed silver nanoparticles with an average particle size of 28.4 nm. FTIR showed the structure and respective bands of the synthesized nanoparticles and the stretch of bonds. Green synthesized silver nanoparticles by cannonball leaf extract show cytotoxicity to human breast cancer cell line (MCF-7). Overall, this environmentally friendly method of biological silver nanoparticles production provides rates of synthesis faster than or comparable to those of chemical methods and can potentially be used in various human contacting areas such as cosmetics, foods, and medical applications.

Background: The present study was aimed at phyto-synthesized silver nanoparticles (AgNPs) using Amygdalus spinosissima (A. spinosissima) extract and to investigate the antibacterial, antioxidant effects, anticancer and apoptotic effects of phyto-synthe-sized AgNPs. Methods: The bio-fabricated AgNPs were characterized using UV-visible spectroscopy (UV-visible), X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) and Energy Disper-sive X-ray (EDX). Results: The phyto-synthesized AgNPs showed maximum absorption in 438 nm, in the UV-visible spectrum. XRD peaks were observed at 2θ values in 38.20°, 44.40°, 64.60°, and 77.50° which are indexed as (111), (200), (220), and (311) bands of Face-Centered Cubic (FCC) structures of silver. FTIR analysis indicated that the AgNPs were capped with A. spinosissima extract. SEM and TEM micrographs revealed that the fabricated AgNPs were spherical and the average size range was 17.89 nm. Also, the EDX results show that the content of Ag was 90%. Conclusion: The phyto-synthesized AgNPs had significant antibacterial activity against Gram-negative bacteria, as well as, the AgNPs exhibited great inhibitory effects on DPPH radicals and their antioxidant properties were favorably comparable to the antioxidant outcomes of ascorbic acid. Moreover, the AgNPs showed anti-cancer activity against the MCF-7 cell line with the IC50=6.1 µg/ml. Moreover, the phyto-synthesized AgNPs could induce apoptosis in the MCF-7 cell line significantly. The GC-MS analysis of the A. spinosissima extract showed that 102 bioactive phyto-chemical compounds, which be of use to the synthesis of AgNPs.

Objective: To evaluate the potential aspects of biologically synthesized silver nanoparticles mediated by Broussonetia papyrifera against the human pathogens. The same is acknowledged to have high efficiency in the field of Pharmaceutical industry.Methods: The 1Mm of AgNO3 is prepared and mixed with appropriate volume of plant extract and reaction volume was made up to 100 ml. the physical   characterization of AgNPs was done. The anti-microbial activity was done against dread pathogens. Cytotoxic activity of the AgNPs was investigated against breast and lung cancer cell lines.Results: The FESEM and EDAX of the microscopic level showed the particle surface measurements around 44 nm to 50 nm. The XRD investigations are being an evidence for the crystalline structure of the AgNPs with 30 nm. The bacterial pathogen Rhodococcus rhodochrous showed the maximum zone of inhibition (11.8±0.447). The A549 human lung cancer cell line and MCF-7 human breast cancer cell line were tested against the toxicity of AgNPs. The toxicity of AgNPs was valued and corresponding IC50 for Lung cancer (A549) is 12.95± 0.05 µg/mL and Breast cancer (MCF-7) is 10.75± 0.05 µg/mL respectively.Conclusion: The present research denotes that biomolecules derived AgNPs have larger impact as antimicrobials in the biomedical field. Since the aggressive chemicals are not involved AgNPs production, these bio-substances can of alternative medicine to resistant once. The in-vitro experiments exhibits the therapeutic effect of this AgNPs based on the ambient concentration on the process.KEYWORDS: Cancer activity, Antimicrobial agents, Resistance, Silver nanoparticles.

Background Cancer is one of the leading causes of mortality. The recent experiments with high-diluted preparations have shown anticancer effects in in-vitro and vivo models. The fundamental principle of homeopathy suggests that the substances capable of producing certain diseases may have a capacity to alter the same disease if used in the ultra-dilute-potentized form. This hypothesis led certain carcinogens for examining their potential anti-cancer efficacy. Method Sulforhodamine B assay is useful in determining the cytotoxicity in cell-based studies in evaluating anticancer agents. The protocol involved preparation of homeopathy dilutions, incubation of cells with homeopathy dilutions, SRB binding, and measurement of absorbance. Cells were treated with 30 potencies of HIV nosode, Hepatitis C nosode, Carcinosin, Cancer nosode, and Ethanol along with positive control (Adriamycin). The preparations were tested in HeLa, HepG2, A549, MCF 7, T 24, Jurkat, SCC 40, and HL-60 cell-lines. Results The homeopathic preparations have shown the anticancer activity measured as percentage growth inhibition. All the homeopathy preparations studied, exhibited anticancer activity on HeLa, HepG2, A 549, T 24, and HL-60 cells. Carcinosin showed the anticancer activity on the SCC 40 cells. Hepatitis C nosode, Carcinosin, and Cancer nosode have shown the anticancer activity on breast cancer cell line MCF-7. None of the preparations exhibited anticancer activity on Human Leukemia Cell Line. Conclusion High-dilution, potentized preparations of certain carcinogens have demonstrated anti-cancer, cytotoxic effects in the cell-line model, supporting the rationale of the fundamental homeopathic principle the Law of Similars, opening windows to its wider applications in healthcare.
