Synthesis and properties of artificial base pairs by use of halogen bonds was written by Tawarada, Ryuya;Seio, Kohji;Sekine, Mitsuo. And the article was included in Nucleic Acids Symposium Series in 2006.Recommanded Product: 15813-09-9 This article mentions the following:
Artificial base pairs by use of halogen bonding were designed and their interaction energies were estimated by ab initio calculations The optimized structures of the artificial base pairs were almost consistent with those of the canonical base pairs, and the interaction energies were ca. 5-11 kcal/mol. To investigate the thermal stability of the base pairs containing halogen bonds in oligodeoxynucleotide duplexes, deoxynucleoside 3′-phosphoramidite building blocks as halogen bonding acceptors and donors were synthesized and used for incorporation into oligodeoxynucleotides. UV-melting experiments suggest that these halogen bonding base pairs have low stability compared with the A-T base pair. Furthermore, the effect of the halogen bonding on stabilization of duplexes was studied in detail by comparison with the hybridization ability of oligodeoxynucleotides containing a modified base having a iodo group with that of the complementary DNA strands lacking the donor site. In the experiment, the researchers used many compounds, for example, 4,5-Diiodo-1H-imidazole (cas: 15813-09-9Recommanded Product: 15813-09-9).
4,5-Diiodo-1H-imidazole (cas: 15813-09-9) belongs to iodide derivatives. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Recommanded Product: 15813-09-9
