Abstract
In this work, we have synthesized pyrimidine derivatives of Schiff base ligand 2-(4,6-dimethoxypyrimidin-2-ylimino)methyl)-6-methoxyphenol (DPMM) stabilized copper nanoparticles (DPMM-CuNPs) and nickel nanoparticles (DPMM-NiNPs) by modified Brust-Schiffrin technique as two step phase transfer assisted method and confirmed by UV-Visible, SEM and TEM analysis. The free radical scavenging activity of DPMM, DPMM-CuNPs &DPMM-NiNPs with 2, 2'-diphenylpicryl hydrazyl (DPPH), hydrogen peroxide (H2O2) super oxide dismutase (SOD) and nitric oxide (NO) shows that the antioxidant activity of DPMM-CuNPs is higher than DPMM &DPMM-NiNPs. Interaction study of DPMM-CuNPs &DPMM-NiNPs with CT-DNA has been investigated by absorption spectral titration, fluorescence studies, cyclic voltammetry and viscometric measurements. Dose dependent antibacterial and antifungal studies of DPMM-CuNPs & DPMM-NiNPs against five different bacteria Shigella sonnei, Staphylococcus aureus, Escherichia coli, Klepsiella pneumoniae, Pseudomonas fluoroscens and five different fungi Aspergillus niger, Candida albicans, Candida tropicalis, Mucor indicus and Rhizopus show that the compounds have significant antibacterial and antifungal activity. Cytotoxicity studies of DPMM-CuNPs &DPMM-NiNPs on human breast cancer cell line (MCF-7) were studied by 3-(4, 5-dimethylthiazol-2-yl-)-2, 5-diphenyltetrazolium bromide (MTT) assay. 50% cell viability was found at 25μg/mL for DPMM-CuNPs and 300μg/mL for DPMM-NiNPs. Collective biological results reveal that the synthesized DPMM-CuNPs is more biologically active than DPMM-NiNPs.

New pyrimidine based ligand capped gold and platinum nano particles: Synthesis, characterization, antimicrobial, antioxidant, DNA interaction and in vitro anticancer activities. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2017; 176:44-53.

Abstract
In this research work, we have synthesized new pyrimidine based Schiff base ligand, 2-((4,6-dimethoxypyrimidine-2-yl)methyleneenamino)-6-methoxyphenol (DPMM) capped gold (Au) and platinum (Pt) nanoparticles (NPs) by modified Brust-Schiffrin method. The characteristics of DPMM-Au NPs and DPMM-Pt NPs have been examined by UV-Visible, FTIR, SEM, TEM and powder XRD analysis. SEM analysis result shows that surface morphology of the DPMM-Au NPs and DPMM-Pt NPs are in granular and spherical shape, correspondingly. The size of the DPMM-Au NPs and DPMM-Pt NPs are approximately 38.14±4.5 and 58.64±3.0nm respectively, which confirmed by TEM analysis. The DPMM-Au NPs and DPMM-Pt NPs have potent antimicrobial against Escherichia coli, Klebsiella pneumonia, Pseudomonas fluorescens, Shigella sonnei, Staphylococcus aureus and Aspergillus niger, Candida albicans, Candida tropicalis, Mucor indicus, Rhizopus strains. The DPMM-Au NPs and DPMM-Pt NPs have good antioxidant activities than the free ligand (DPMM). The spectroscopic and viscometric measurement confirms the hydrophobic DNA binding abilities of the newly prepared DPMM capped metal NPs. Moreover, the in vitro anticancer activity of DPMM, DPMM-Au NPs and DPMM-Pt NPs against cancer (MCF-7, HeLa & HEp2) and normal (NHDF) cell lines have performed using MTT assay. These results reveals that, DPMM-Au NPs and DPMM-Pt NPs having significant cytotoxic activity against the cancer cell lines and least toxic effect on normal cell line as compared to standard drug cisplatin.

C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2013; 33:884-91. [PMID: 25427502 DOI: 10.1016/j.msec.2012.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2011] [Revised: 09/02/2012] [Accepted: 11/11/2012] [Indexed: 11/15/2022]
Abstract
This research work reports the in vitro antitumor personality of few novel peptide nanocomplexes synthesized via a phase-assisted, modified Brust-Schiffrin methodology. Here, a series of metallo(copper, cobalt, nickel and zinc) nanocomplexes engineered with a pre-prepared peptide [N,N'-(1,2-ethylene)-bis-hippuricamide] have been synthesized for damaging the Dalton's lymphoma ascites tumor model. All the peptide nanocomplexes are spectrally, thermally and morphologically examined. The peptide bound zinc and cobalt nanocomplexes deliver excellent antitumor behavior against both the animal and human cancer cell lines, which has been pre-documented by their efficient DNA damaging skills under physiological conditions. Additionally, all the nanocomplexes are evaluated for the inhibition of microbial augmentation against few fungal and bacterial strains. The above results demonstrate that, a consecutive development of these kinds of peptide nanocomplexes may exemplify their uniqueness in biomedical applications as useful molecular-level devices.
