Interactions between DNA/RNA and huge variety of peptides are quite common in nature, controlling vast number of processes. Also, there are several naturally occurring small molecules which contain peptide and DNA intercalator in structure, whereby their biological activity is based on synergistic interactions of both components; for instance(More)
An investigation of the interactions of two novel and several known DBTAA-adenine conjugates with double-stranded DNA and RNA has revealed the DNA/RNA groove as the dominant binding site, which is in contrast to the majority of previously studied DBTAA analogues (DNA/RNA intercalators). Only DBTAA-propyladenine conjugates revealed the molecular recognition(More)
BACKGROUND In order to increase the effectiveness of cancer treatment, new compounds with potential anticancer activities are synthesized and screened. Here we present the screening of a new class of compounds, 1-(2-picolyl)-, 4-(2-picolyl)-, 1-(2-pyridyl)-, and 4-(2-pyridyl)-3-methyl-1,2,3-triazolium salts and 'parent' 1,2,3-triazole precursors. METHODS(More)
We present a study devoted to the utilization of elastic Lamb waves in structural heath monitoring for damage detection in composite material. We pay attention to the detection of these high dispersive and multimode waves in large range specimen. In contrast to known methods using piezoelectric, fiber Bragg grating and Fabry-Perot interferometer sensors, we(More)
Binding modes of a dibenzotetraaza14annulene (DBTAA) derivative with synthetic nucleic acids were studied using surface-enhanced Raman spectroscopy (SERS). Changes in SERS intensity and appearance of new bands in spectra were attributed to different complexes formed between the DBTAA molecules and DNA/RNA polynucleotides. A decrease in intensity pointed(More)
We have previously demonstrated the nucleic acid binding capacity of phenanthridine derivatives (PHTs). Because nucleic acids are potent inducers of innate immune response through Toll-like receptors (TLRs), and because PTHs bear a structural resemblance to commonly used synthetic ligands for TLR7/8, we hypothesized that PHTs could modulate/activate immune(More)
Three dibenzotetraaza[14]annulenes non-covalently interacted with double-stranded DNA and RNA by mixed minor groove and/or intercalative binding mode. Observed interactions were strongly dependent on the steric exposure of positive charges and the length of the linkers of studied compounds as well as on the secondary structure and basepair composition of(More)
We present a development study of a robust inter-ferometric transducer for elastic deformations excited by mechanical vibrations. In contrast to known methods using piezoelectric, fiber Bragg grating and Fabry-Perot interferometer sensors, we deal with pronounced spatially distributed transduction based on arbitrary shaped fiber segments like fiber optic(More)
Based on previously reported antiproliferative activity screening, four most promising disubstituted 2-phenylbenzothiazole hydrochlorides were chosen for detailed study. Water solubility, as well as liphophilicity/hydrophilicity balance of organic core were modified by conversion to mesylate salts. For purpose of structure/activity studies their structures(More)
