Human telomeric DNA (hTelo), present at the ends of chromosomes to protect their integrity during cell division, comprises tandem repeats of the sequence d(TTAGGG) which is known to form a G-quadruplex secondary structure. This unique structural formation of DNA is distinct from the well-known helical structure that most genomic DNA is thought to adopt, and has recently gained prominence as a molecular target for new types of anticancer agents. In particular, compounds that can stabilize the intramolecular G-quadruplex formed within the human telomeric DNA sequence can inhibit the activity of the enzyme telomerase which is known to be upregulated in tumor cells and is a major contributor to their immortality. This provides the basis for the discovery and development of small molecules with the potential for selective toxicity toward tumor cells. This review summarizes the various families of small molecules reported in the literature that have telomeric quadruplex stabilizing properties, and assesses the potential for compounds of this type to be developed as novel anticancer therapies. A future perspective is also presented, emphasizing the need for researchers to adopt approaches that will allow the discovery of molecules with more drug-like properties in order to improve the chances of lead molecules reaching the clinic in the next decade.

A triplex-forming oligonucleotide (TFO) can recognize the homopurine-homopyrimidine sequence in DNA duplexes and inhibit the transcription of targeted mRNAs. Recently, we reported that N-acetyl-2,7-diamino-1,8-naphthyridine (DANac), incorporated into a TFO, has high binding ability and base recognition selectivity for the pyrimidine bases in the purine-rich chain of the DNA duplex at pH 7.4. However, it was found in this study that the difference in the Tm values between the pyrimidine bases and purine bases decreased by more than 4 C at pH 6.0?7.0. To improve the low base recognition selectivity of the TFO, we designed a new artificial base, DAQac, with a quinoline skeleton. The Tm values of the triplexes containing DAQac:T-A or DAQac:C-G were more than 13 C higher than those of the triplexes containing DAQac:A-T or DAQac:G-C at pH 7.4. We also observed that under more acidic conditions (pH 6.0?7.0), the base recognition selectivity of DAQac in a triplex was higher than that of DANac, although the binding ability of DAQac in a triplex was similar to that of DANac. Additionally, we found that DAQac, incorporated into the TFO, could accurately recognize the MeC-G base pair in the hairpin DNA, similar to the C-G base pair.

Keeping in view the ever growing demand and application of the organic small molecules based sensitive and selective fluorescence detection strategies for the trace metallic ions in the ecosystem, fluids and inside intracellular media, the present literature survey was focused on the recent development on the organic skeleton based fluorescence sensor for the zinc ion as Zn2+ is the second most abundant transition metal after iron in human body. The prominent organic based skeletons introduced during the past three years for zinc detection including azine, ((Z)-N¡ä-(quinolin-2-ylmethylene)furan-2-carbohydrazide), nicotinohydrazide, hydrazone, phenolic cage, 4-methyl-2,6-bis[(E)-(2-(4-phenylthiazol-2-yl)hydrazono)methyl]phenol, bipyridine, N-(quinoline-8-yl)pyridine-2-carboxamide, anthracene, Schiff base, salen, helicene, Carbon Quantum Dots (CDs) func-tionalized with Calix[4]arene, coumarin, diaminomaleonitrile, peptide, hydroxypyrazole, salicylhydrazide were discussed in detail with particular focus on ligand-zinc complexation mechanism, UV-visible and fluorescence investigation, spectral variation, isosbestic emergence, limit of detection, ligand-zinc binding stoichiometry, association/binding constant and applications for intracellular tracing of metallic contamination via confocal fluorescence microscopic studies. Among the several discussed optical probes, rhodamine and fluorescein based material offer appreciable sensitivity, exhibiting drawback of pH sensitivity. Probes based on these ligands triggered ?turn-on? signal even in the absence of metals upon fluctuation in pH e.g., acidic in former case and basic in the latter case. Hydroxypyrazole-based ligands also showed detection signal variation by switching the pH of the solution. Schiff base and bipyridyl scaffold were found to possess good ligation toward the several transition metals. Azole, oxazole, thiazole, thiadiazole, hydrazine carboxamide and hydrazine car-bothiomide are the bioactive molecules exhibiting good cell viability and probes designed by using these central nucleus might be better to invest for intracellular imaging. Symmetrical heterocyclic cage like probe showed better chelation toward several transition metals and it is a good choice for the design and development of sensor for simultaneous detection of several transition metals.

Despite the rapid development of modern methods of cancer treatments, chemotherapy is still one of the most important, and sometimes, the only one method of therapy. The development of cancer treatment methods indicates that search of the new, more effective and safer medicines are necessary. Treatment using common anticancer drugs is associated with their interaction with DNA. Further research on the binding of metal ions and their complexes to DNA resulted from their potential applications as new therapeutic and diagnostic agents. It is well known that mutations in DNA play a significant role in the formation of tumors, however not all of these processes are known. The recognition of binding lanthanide(III) ions or lanthanide(III) complexes to DNA and cleavage DNA via lanthanide(III) complexes are important to understand unknown mutations that lead to cancer and treatment of this disease. The scientists have been undertaking various attempts to interfere the human DNA in order to overcome genetic diseases. Gene therapy could be considered as a kind of scissors that allow to cleavage the DNA in the proper place and insert the corrective gene. Lanthanide(III) ions and their complexes, due to their unique properties, could be widely used as luminescent probes for bioassays and as reagents in optical and magnetic resonance imaging. The luminescence properties of these compounds also have been adopted in medicinal diagnosis. This review will summarize the role of lanthanide(III) ions and their compounds in recent studies on the use of lanthanide(III) complexes to bind, cleavage of DNA also in diagnosis, and monitoring the treatment of cancer disease.

Molecular structure of a naphthyridine and pyrazine amine ligand, N2,N7-di (pyrazin-2-yl)-1,8-naphthyri-dine-2,7-diamine (H2dpznda 1) was studied, and a three-dimensional supramolecular network with a double helix chain structure through intermolecular hydrogen bonds and pi-pi interactions between the naphthyridine and pyrazine rings was depicted. Through ligand 1, [Co2 (mu 2-dpznda) 2 (mu 2-CH3OH) 2] (2) was obtained and two ligands coordinate to two Co2+ as tetradentate bridging ligands. Single crystal and magnetism study on 2 revealed that the complex exhibited weak yet significant metal-metal interaction.
