Bagheri, Sotoodeh research published 《 Theoretical study of hydrogen bonds and electronic properties in hexagonal arrangements composed of self-assembled DNA analogues》, the research content is summarized as follows. Abstract: Aminopyrimidine, triaminopyrimidine, and cyanuric acid as artificial bases can be used to design and prepare multi-stranded DNA structures. In this manuscript, we theor. investigate the stability of hydrogen-bonded hexagonal structures arising from the self-assembly of aminopyrimidine and cyanuric acid, as well as triaminopyrimidine and cyanuric acid in gas phase and in water. The influence of hydrogen bonds on the stability of hexagonal arrangements is examined by atoms in mols. and natural bond orbital analyses. Moreover, the mutual effects of hydrogen bonds on each other are also evaluated in the hexagonal structures using cooperative energy. Whereas the self-assembly of the hydrogen-bonded hexagonal arrangements may be considered to form new nanostructures, metal sensors, and ion channels, some electronic properties such as band gap, first ionization energy, electron affinity, electronegativity, electronic chem. potential, electrophilicity index, global chem. hardness, and chem. softness are theor. estimated at M06-2X/6-311++G(d,p) level.

Computed Properties of 4595-59-9, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., 4595-59-9.

The nomenclature of pyrimidines is straightforward. However, like other heterocyclics, tautomeric hydroxyl groups yield complications since they exist primarily in the cyclic amide form. 4595-59-9, formula is C4H3BrN2, Name is 5-Bromopyrimidine. For example, 2-hydroxypyrimidine is more properly named 2-pyrimidone. A partial list of trivial names of various pyrimidines exists. Computed Properties of 4595-59-9.

Bag, Sukdev;Jana, Sadhan;Pradhan, Sukumar;Bhowmick, Suman;Goswami, Nupur;Sinha, Soumya Kumar;Maiti, Debabrata research published 《 Imine as a linchpin approach for meta-C-H functionalization》, the research content is summarized as follows. An temporary directing group (TDG) for meta-C-H functionalization via reversible imine formation were reported. By overruling facile ortho-C-H bond activation by imine-N atom, a suitably designed pyrimidine-based TDG successfully delivered selective meta-C-C bond formation. Application of this temporary directing group strategy for streamlining the synthesis of complex organic mols. without any necessary pre-functionalization at the meta position were explored.

Application of cas: 18592-13-7 | Naguib, Fardos N. M. et al. published an article in 1989

6-(Chloromethyl)pyrimidine-2,4(1H,3H)-dione (cas: 18592-13-7 Recommanded Product: 18592-13-7) was used in the synthesis of: 5-bromo-6-(chloromethyl)uracil, pteridine compounds, potential anticancer agents, substituted uracil pyridinium compounds, potential inhibitors of thymidine phosphorylase.

Recommanded Product: 18592-13-7In 1989, Naguib, Fardos N. M.;El Kouni, Mahmoud H.;Cha, Sungman published 《Structure-activity relationship of ligands of dihydrouracil dehydrogenase from mouse liver》. 《Biochemical Pharmacology》published the findings. The article contains the following contents:

One hundred and five nucleobase analogs were screened as inhibitors of dihydrouracil dehydrogenase (DHUDase, EC 1.3.1.2) from mouse liver. 5-Benzyloxybenzyluracil, 1-deazauracil (2,6-pyridinediol), 3-deazauracil (2,4-pyridinediol), 5-benzyluracil, 5-nitrobarbituric acid and 5,6-dioxyuracil (alloxan) were identified as potent inhibitors of this activity, with apparent Ki values of 0.2, 0.5, 2.1, 3.4, 3.8 and 6.6 μM resp. Both 5-benzyloxybenzyluracil and 1-deazauracil were also potent inhibitors of DHUDase from human livers. These findings along with an extensive review of literature allowed the formulation of a structure-activity relationship. The binding to DHUDase required intact C2 and C4 oxo groups. Replacement of N1 or N3 by an endocyclic carbon enhanced binding. In contrast, replacement of C5 or C6 by an endocyclic nitrogen abolished binding. Addition of a charged group to C5 and/or C6, and of a hydrophobic group to C5 but not C6 improved the binding. To complete the study, the researchers used 6-(Chloromethyl)pyrimidine-2,4(1H,3H)-dione (cas: 18592-13-7) .

6-(Chloromethyl)pyrimidine-2,4(1H,3H)-dione (cas: 18592-13-7 Recommanded Product: 18592-13-7) was used in the synthesis of: 5-bromo-6-(chloromethyl)uracil, pteridine compounds, potential anticancer agents, substituted uracil pyridinium compounds, potential inhibitors of thymidine phosphorylase.
