Nanomedicine is growing due to the development of new medical diagnostic tools and new nanostructure-based therapies that exert direct biological action or function as pharmacological carriers. Nanoparticles (NPs) synthesis provides an eco-friendly approach for different applications. Among NPs, silver NPs (AgNPs) are gaining considerable research interest due to their broad range of activity and their usability in the medical and biotechnology fields. In this study, a new AgNP synthesis method was developed using an aqueous pigeon dropping (PD) extract in silver nitrate (AgNO3). The rapid of AgNPs yield was detected visually. Analysis of UV-vis spectroscopy, energy-dispersive X-ray spectroscopy (EDX), dynamic light scattering (DLS) and electron microscopy (TEM) transmission showed a spherical or near spherical shape of AgNPs with mean size of 135 nm. AgNPs antimicrobial activities (anti-bacterial and anti-fungal) were determined using agar well diffusion method. These NPs further screened for anticancer activity in vitro using A-549 and MCF-7 cell lines. The results showed that the inhibition zone for the obtained PD AgNPs versus Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus were 26, 18, 17 and 15 mm, respectively. PD AgNPs showed the highest antifungal effect against Aspergillus flavus and the lowest effect against Penicillium griseofulvum. In vitro anti-cancer activities showed that the inhibitory concentration of 50% (IC50) of AgNPs was 10.3 ± 1.15 and 12.19 ± 0.75 µg mL−1 against A-549 and MCF-7 cancer cell lines, respectively.

A study was carried out to screen for phytochemical constituents and assess the antioxidant and antimicrobial activities of Senna alata and Senna tora leaf extracts. The leaves were first dried at room temperature and 50°C in an oven prior to solvent extraction using ethanol and methanol. The in-vitro qualitative assays showed that both S. alata and S. tora leaf extracts contained bioactive and secondary metabolites components such as tannins, steroids, saponin, terpenoids, glycosides, flavonoids and phenols. The antioxidant activity and capacity test were carried out by conducting free radical of 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity and Ferric reduction antioxidant plasma (FRAP) assays. Both assays showed S. tora leaf extract has higher antioxidant capacity than S. alata leaf extract. The efficacy of these leaf extracts were tested against skin pathogens through agar well diffusion method. S. alata extract showed an inhibition zone (1.15 – 1.59 mm) against Pseudomonas aeruginosa while S. tora extracts exhibited a strong antimicrobial activity against S. epidermidis (inhibition zone of 12 – 16.94 mm) followed by P. aeruginosa (inhibition zone of 1 – 1.59 mm). Nonetheless, no inhibition zone was observed for S. aureus by both leaf extracts. The phytochemicals and antioxidant constituents as well as inhibitory potential on skin pathogens possessed by S. alata and S. tora leave highlighted their potential utilization in the development of natural drugs or cosmetics to treat skin related diseases or infections.

AbstractASP was used to synthesize FeNPA. They were characterized by UV-vis spectroscopy, FT-IR, TEM, SEM, XRD and ZP. The aim of this study was to evaluate in vitro cytotoxic activity and antioxidant acitivities of FeNPA and ASP. The antioxidant properties were evaluated using DPPH, ABTS+ and H2O2 assays. FeNPA had higher antioxidant activity comparing to ASP according to DPPH (IC50: 3.48 μg/mL) and ABTS+ (60.52%) assays. Anti-cancer activities of FeNPA and ASP were investigated in breast cancer, melanoma and control cell lines. FeNPA was more cytotoxic than ASP in MCF-7, MeWo, CHL-1, and HEL 299 cells. FeNPA had shown that mitochondria induce apoptosis through stress in MDA-MB-231, and cells MeWo. ASP also induced apoptosis 2.23-fold in MCF-7 cells. Progesterone receptor gene expression showed a 10-fold increase in a hormone-dependent MCF-7 cell line in ASP, and FeNPA treatment. Expressions of BCL6, CXCL12, DNAJC15, RB1 and TPM1 in melanoma cancer cell lines were significantly increased in ASP and FeNPA administration. It had been shown that FeNPA regulates gene expressions that may be considered important in terms of prognosis in breast cancer and melanoma cell lines and it is suggested that gene expressions regulated by FeNPA are also evaluated in animal models in vivo.

N-(benzothiazol-2-yl)benzenesulphonamide (BS2ABT) was synthesized by the condensation (by refluxing) of 2-aminobenzothiazole and benzenesulphonylchloride in acetone at 140ºC. The resulting crude precipitates were recrystallized from dimethylformamide (DMF). Five metal complexes of copper(I), nickel(II), manganese(II), cobalt(II) and zinc(II) of the ligands were synthesized. The compounds were characterized using magnetic susceptibility measurements, UV/VIS spectrophotometry, infra red, proton and13C nmr spectroscopies. The antimicrobial tests of the ligands and its metal complexes were carried out on both multi-resistant bacterial strains isolated under clinical conditions and cultured species using agar-well diffusion method. The multi-resistant bacterial strains used wereEscherichia coli, Proteusspecies,Pseudomonas aeroginosa and Staphylococcus aureuswhich were isolated from dogs. The culture species werePseudomonas aeruginosa(ATCC 27853),Escherichia Coli(ATCC 25922)Staphylococcus aureus(ATCC 25923), and the fungi,Candida krusei(ATCC 6258) andCandida albicans(ATCC 90028). The tests were bothin vitroandin vivo. Thus the Inhibition Zone Diameter (IZD), the Minimum Inhibitory Concentration (MIC), and the Lethal and Effective Concentrations (LC50and EC50) were determined. The antimicrobial activities of the compounds were compared with those of Ciprofloxacin and trimethoprim-sulphamethoxazole as antibacterial agents and Fluconazole as an antifungal drug. All the compounds showed varying activities against the cultured typed bacteria and fungi used. However, they were less active than the standard drugs used except Fluconazole which did not show any activity againstCandida krusei(ATCC 6258) but most of the compounds synthesized were very active against it. The Lethal Concentration (LC50) ranged from 26.25±4.9-1833.88±186.92 ppm. These are within the permissible concentrations.

Background: Due to the astonishing properties of ferrocene and its derivatives, it has a broad application in diverse areas. Numerous ferrocene derivatives demonstrated anti-proliferative activity. Also COX-2, as a key isoenzyme for production of prostaglandins, is frequently overexpressed in various cancers. It is now recognized that COX-2 over expression promotes tumorigenic functions which can be suppressed by COX-2 inhibitors, a phenomenon useful for the preventing of tumor progression. The combination of COX-2 inhibitors with other anti-cancer or cancer prevention drugs may reduce their side effects in future cancer prevention and treatment. Objective: Owing to high anticancer potential of ferrocene derivatives and considerable COX-2 inhibitory and cytotoxicity effects of our previously synthesized chalcones, we decided to incorporate the ferrocenyl moiety into appropriate COX-2 inhibitor chalcone based scaffold, to evaluate COX-2 inhibitory activity as well as anticancer activities. Methods: Chalcones were synthesized via clasien-schmidt condensation of methylsulfonyl aldehyde and acetyl ferrocene. Further different amines with solvent free and ultra sound condition were reacted with chalcones to have different 1-ferrocenyl-3-amino carbonyl compounds. Docking study was carried out with Auto Dock vina software. All the newly-synthesized compounds were evaluated for their cyclooxygenase-2 (COX-2) inhibitory activity using chemiluminescent enzyme assays as well as cytotoxicity activity against MCF-7 and T47D and fibroblast cell lines by MTT assay. Results: In vitro COX-1/COX-2 inhibition studies demonstrated that all compounds were selective inhibitors of the COX-2 isozyme with IC50 values in the highly potent 0.05-0.12 µM range, and COX-2 selectivity indexes (SI) in the 148.3-313.7 range. These results indicated that either potency or selectivity of COX-2 inhibitory activity was affected by the nature and size of the substituents on C-3 of propane-1-one. Also anti-proliferative and toxicity activities of synthesized compounds against breast cancer cell lines MCF-7 and T47D and fibroblast cell lines showed that the synthesized compounds had mild to moderate cytotoxicity against MCT7 and T47D breast cancer cell lines at 10 µM concentration. In vitro COX-1/COX-2 inhibition studies and anticancer activity against MCF-7, identified 1-ferrocenyl-3-(4-methylsulfonylphenyl) propen-1-one as a potent compound (IC50 COX-2 = 0.05 µM, MCF-7: % inhibition (at concentration of 10 µM) = 32.7%), and also 1-ferrocenyl-3- (propan-1-amine)-3-(4-methylsulfonylphenyl) propan-1-one showed the most selectivity on COX-2 inhibition (selectivity index= 313.7). Conclusion: A novel group of ferrocene compounds, possessing a methyl sulfonyl COX-2 pharmacophore were synthesized to investigate the effect of different substituents on selectivity and potency of COX-2 inhibitory activity and their cytotoxicity effects. This study indicates that 1-ferrocenyl-3-amino carbonyl compounds having ferrocene motif and methyl sulfonyl COX-2 pharmacophore is a suitable scaffold to design COX-2 inhibitors and anti-cancer agents.
