Screening DNA-targeted anticancer drug in vitro based on cancer cells DNA-templated silver nanoclusters. Sci Rep 2019; 9:8911.

Abstract
A reliable and sensitive cancer cells DNA-templated silver nanoclusters probe has been proposed for screening DNA-targeted anticancer drugs in vitro. In this paper, the DNA-templated silver nanoclusters was used to investigate the binding between anthracycline antibiotics and DNA. The template of DNA-templated silver nanoclusters was extracted from human liver carcinoma cells directly, which can express the drug activities against cancer cells more direct than the normal cells DNA. The anti-tumor activities of the four drugs were validated by MTT and apoptotic assay as Mitoxantrone > Epirubicin > Daunorubicin > Adriamycin.

A Rapid Screening Analysis of Antioxidant Compounds in Native Australian Food Plants Using Multiplexed Detection with Active Flow Technology Columns. Molecules 2016; 21:E118. [PMID: 26805792 PMCID: PMC6273279 DOI: 10.3390/molecules21010118] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2015] [Revised: 01/11/2016] [Accepted: 01/11/2016] [Indexed: 11/17/2022] Open
Abstract
Conventional techniques for identifying antioxidant and phenolic compounds in native Australian food plants are laborious and time-consuming. Here, we present a multiplexed detection technique that reduces analysis time without compromising separation performance. This technique is achieved using Active Flow Technology-Parallel Segmented Flow (AFT-PSF) columns. Extracts from cinnamon myrtle (Backhousia myrtifolia) and lemon myrtle (Backhousia citriodora) leaves were analysed via multiplexed detection using an AFT-PSF column with underivatised UV-VIS, mass spectroscopy (MS), and the 2,2-diphenyl-1-picrylhydrazyl (DPPH•) derivatisation for antioxidants as detection methods. A number of antioxidant compounds were detected in the extracts of each leaf extract.
