Abstract The current study presents a new class of functional derivatives ( 1–3 ) consisting dicationic viologen (4,4’-bipyridinium unit) V 2+ capped by nucleobases thymine NB 1 ), adenine 2 thymine/adenine , and ion-paired with amphiphilic anion 3,4,5-tris(dodecyloxy)benzene sulfonate DOBS − ). target our work focuses on the design synthesis molecular building blocks in which three different f...

The regular arrangement of complementary diaminopyridine-thymine (DAP-THY) on alternating copolymers permits cooperative binding events and the effective formation of well-controlled micrometre-scale aggregates.

In the search to obtain new and more efficient components of memory devices, we report photochromic, dielectric electrochemical response a light-responsive organic compound, its performance under electrical fields. The so-called N(1)-[12-(4-(4?-isobutyloxyphenyldiazo)phenoxy)dodecyloxy)]thymine, tAZOi, molecule contains one azobenzene group, which provides with photochromic character, terminal ...

Thymineless death (TD), the loss by a thymine-requiring auxotroph of the ability to multiply after a period of thymine starvation, was first described1 in Escherichia coli 15T-, and was attributed to "unbalanced growth," the synthesis of RNA and protein in the absence of DNA synthesis. This phenomenon has been investigated in thymineless auxotrophs of a number of bacterial species: E. coli 15Ta...

In this work, addition of OH(-) to one-electron oxidized thymidine (dThd) and thymine nucleotides in basic aqueous glasses is investigated. At pHs ca. 9-10 where the thymine base is largely deprotonated at N3, one-electron oxidation of the thymine base by Cl(2)(•-) at ca. 155 K results in formation of a neutral thyminyl radical, T(-H)·. Assignment to T(-H)· is confirmed by employing (15)N subst...

We report herein the structuring of single-stranded thymine-rich DNA sequences into peptide-DNA hairpin triplex structures via designed melamine-thymine nucleobase recognition. Melamine-displaying α-peptides were synthesized with the general form (EM*)n, where M* denotes a lysine residue side chain derivatized with melamine, a bifacial hydrogen bond complement for thymine. We have found that (E...

Some of the DNA from the tsar's mitochondria--cellular organelles with their own DNA--didn't quite match that of his living relatives. Forensic experts thought that most people carry only one type of mitochondrial DNA(mtDNA), but the tsar had two: The same site sometimes contained a cytosine and sometimes a thymine. His relatives had only thymine, a mismatch that fueled controversy over the aut...
