Synthesis and biophysical analysis of modified thymine-containing DNA oligonucleotides.
We report the synthesis of a 5-formyl-2'-deoxyuridine (5fU) phosphoramidite and the preparation of oligonucleotides comprising all known, naturally observed eukaryotic thymidine modifications. Biophysical characterization of the synthetic oligonucleotides indicates that 5fU, but not the other T-derivatives, can alter DNA structures.
متن کاملBiophysical and transfection properties of DNA-DiC14-amidine complexes.
DiC14-amidine (N-t-butyl-N°-tetradecylaminopropionamidine) is a cationic lipid used as transfection agent in vitro [1] and as a vector for in vivo gene therapy applications. DiC14-amidine molecules assemble in a liposomal structure (transition temperature: 23C-critical micelle concentration: 10-7 M). Compared to other cationic lipids, diC14-amidine does not require a helper lipid. This property...
متن کاملThe Relationship between Modified Biophysical Profile, Standard Biophysical Profile, and Neonatal Outcomes of High-risk Pregnancies
Introduction: High-risk pregnancies can result in many complications for the fetus. In these pregnancies, different tests such as non-stress test (NST), biophysical profile (BPP), oxytocin contraction stress test (OCT), and Doppler sonography can be used to evaluate fetal health. As standard BBP requires more time and expertise, in this study, we evaluated the relationship between standard BPP,...
متن کاملAmine-rich Silver Complexes of rac-trans-1,2-Diaminocyclohexane
The use of the diamine rac-trans-1,2-diaminocyclohexane (LL) as a major component of the solvent system allows the isolation of crystalline silver complexes with higher ratios of LL to silver (up to 4 : 1, compared to the previously obtained 1 : 1 in ethanolic solution). The complexes obtained and crystallographically characterized were (LL)2AgNO3 (1), (LL)3Ag(OAc)(H2O)2 (2) and (LL)4AgBr(H2O)3...
