The in cellulo catalytic production of reactive oxygen species (ROS) by copper(II) and iron(II) complexes is now recognized as a major mechanistic model in the design of effective cytotoxins of human cancer. The developmental complex, [Cu(o-phthalate)(1,10-phenanthroline)] (Cu-Ph), was recently reported

The photocleavage of double-stranded and single-stranded DNA by the fluorescent dye YOYO-1 was investigated in real time by using the synchrotron radiation light source ASTRID (ISA, Denmark) both to initiate the reaction and to monitor its progress using Couette flow
Ville Laitala et al.
Analytical chemistry, 77(5), 1483-1487 (2005-03-01)
We report here a novel, time-resolved, lanthanide-based energy-transfer assay utilizing nonoverlapping acceptor fluorophores, which have their absorption energetically at a higher level than the emittive transitions of the donor. The technique was studied by comparing a series of nonoverlapping acceptors
Chris T Middleton et al.
Annual review of physical chemistry, 60, 217-239 (2008-11-18)
Ultraviolet light is strongly absorbed by DNA, producing excited electronic states that sometimes initiate damaging photochemical reactions. Fully mapping the reactive and nonreactive decay pathways available to excited electronic states in DNA is a decades-old quest. Progress toward this goal

Chemphyschem : a European journal of chemical physics and physical chemistry, 10(9-10), 1426-1430 (2009-03-25)
Low-energy electrons (LEEs) interact with a DNA model system to create a variety of excited states. In the gas phase, dissociative (sigma*) states are accessible by LEEs with energy <4 eV (see picture) and cause facile strand breaks through a

Transcriptional programming of the innate immune response is pivotal for host protection. However, the transcriptional mechanisms that link pathogen sensing with innate activation remain poorly understood. During HIV-1 infection, human dendritic cells (DCs) can detect the virus through an innate

Changes in cell fate and identity are essential for endothelial-to-haematopoietic transition (EHT), an embryonic process that generates the first adult populations of haematopoietic stem cells (HSCs) from hemogenic endothelial cells. Dissecting EHT regulation is a critical step towards the production

U6 snRNA is transcribed by RNA polymerase III (Pol III) and has an external upstream promoter that consists of a TATA sequence recognized by the TBP subunit of the Pol III basal transcription factor IIIB and a proximal sequence element
Effect of the alkaline cations on the stability of the model polynucleotide poly(dG-dC)·poly(dG-dC).

Journal of biomolecular structure & dynamics, 29(3), 585-594 (2011-11-10)
When the model polynucleotide poly(dG-dC)∙poly(dG-dC) [polyGC] is titrated with a strong acid (HCl) in unbuffered aqueous solutions containing the chlorides of the alkali metals in the concentration range 0.010 M-0.600 M, two transitions in the absorbance vs. pH plots are evidenced, characterized

There is an unmet need for novel metal-based chemotherapeutics with alternative modes of action compared to clinical agents such as cisplatin and metallo-bleomycin. Recent attention in this field has focused on designing intracellular ROS-mediators as powerful cytotoxins of human cancers

We report a series of copper(II) artificial metallo-nucleases (AMNs) and demonstrate their DNA damaging properties and in-vitro cytotoxicity against human-derived pancreatic cancer cells. The compounds combine a tris-chelating polypyridyl ligand, di-(2-pycolyl)amine (DPA), and a DNA intercalating phenanthrene unit. Their general
