Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Chai, Yingying, once mentioned the application of 3051-09-0, Name is Murexide, molecular formula is C8H8N6O6, molecular weight is 284.1857, MDL number is MFCD00012777, category is pyrimidines. Now introduce a scientific discovery about this category, Computed Properties of C8H8N6O6.
The 2-Amino Group of 8-Aza-7-deaza-7-bromopurine-2,6-diamine and Purine-2,6-diamine as Stabilizer for the Adenine-Thymine Base Pair in Heterochiral DNA with Strands in Anomeric Configuration
Stabilization of DNA is beneficial for many applications in the fields of DNA therapeutics, diagnostics, and materials science. Now, this phenomenon is studied on heterochiral DNA, an autonomous DNA recognition system with complementary strands in alpha-D and beta-D configuration showing parallel strand orientation. The 12-mer heterochiral duplexes were constructed from anomeric (alpha/beta-D) oligonucleotide single-strands. Purine-2,6-diamine and 8-aza-7-deaza-7-bromopurine-2,6-diamine 2 ‘-deoxyribonucleosides having the capability to form tridentate base pairs with dT were used to strengthen the stability of the dA-dT base pair. T-m data and thermodynamic values obtained from UV melting profiles indicated that the 8-aza-7-deaza 2 ‘-deoxyribonucleoside decorated with a bromo substituent is so far the most efficient stabilizer for heterochiral DNA. Compared with that, the stabilizing effect of the purine-2,6-diamine 2 ‘-deoxyribonucleoside is low. Global changes of helix structures were identified by circular dichroism (CD) spectra during melting.
