Small interfering RNAs (siRNAs) represent a novel tool to induce gene silencing in mammalian cells and clinical trials are currently ongoing to assess the therapeutic efficacy of siRNAs in various human diseases, including age-related macular degeneration and respiratory syncytial virus infection.
A quencher-free and enzyme-free fluorescent sensor was proposed to simply and sensitively detect miRNA via the target catalyzed hairpin assembly (CHA) signal amplification in combination with 2-aminopurine (2-AP) molecular beacon (MBs). This sensor contains two DNA hairpins termed as H1 and H2. H1
The biological activity of interferons (IFNs) is presumed to be mediated through the induction of a number of IFN-inducible genes. IFN-mediated gene induction was examined in two human breast cancer cell lines, MCF-7 and BT-20. Both these cell lines were remarkably responsive to IFNs as a number of
Based on 2-aminopurine (2-AP) probe in conjunction with a G-quadruplex structure and signal amplification technique, a simple and highly sensitive fluorescence sensor for detecting microRNA (miRNA) is developed for high signal-to-background ratio and wide linear range. The proposed sensor contains
A novel 6-aminopurine scaffold bearing an N9-cis-cyclobutyl moiety was designed using structure-based molecular design based on two known CDK inhibitors, dinaciclib and Cmpd-27. A series of novel 6-aminopurine compounds was prepared for structure-activity relationship (SAR) studies of CDK2 and CDK5
BACKGROUND
Topoisomerase II poisons are in clinical use as anti-cancer therapy for decades and work by stabilizing the enzyme-induced DNA breaks. In contrast, catalytic inhibitors block the enzyme before DNA scission. Although several catalytic inhibitors of topoisomerase II have been described,
Cyclin-dependent kinases (CDKs) contribute to the cancer hallmarks of uncontrolled proliferation and increased survival. As a result, over the last two decades substantial efforts have been directed towards identification and development of pharmaceutical CDK inhibitors. Insights into the biological
