Peptide nucleic acid Hoogsteen strand linker design for major groove recognition of DNA thymine bases

Sequence-specific targeting of double-stranded DNA and non-coding RNA via triple-helix-forming peptide nucleic acids (PNAs) has attracted considerable attention in therapeutic, diagnostic and nanotechnological fields. An E-base (3-oxo-2,3-dihydropyridazine), attached to the polyamide backbone of a PNA Hoogsteen strand by a side-chain linker molecule, is typically used in the hydrogen bond recognition of the 4-oxo group of thymine and uracil nucleic acid bases in the major groove. We report on the application of quantum chemical computational methods, in conjunction with spatial constraints derived from the experimental structure of a homopyrimidine PNA center dot DNA-PNA hetero-triplex, to investigate the influence of linker flexibility on binding interactions of the E-base with thymine and uracil bases in geometry-optimised model systems. Hydrogen bond formation between the N2 E-base atom and target pyrimidine base 4-oxo groups in model systems containing a beta-alanine linker (J Am Chem Soc 119:11116, 1997) was found to incur significant internal strain energy and the potential disruption of intra-stand aromatic base stacking interactions in an oligomeric context. In geometry-optimised model systems containing a 3-trans olefin linker (Bioorg Med Chem Lett 14:1551, 2004) the E-base swung out away from the target pyrimidine bases into the solvent. These findings are in qualitative agreement with calorimetric measurements in hybridisation experiments at T-A and U-A inversion sites. In contrast, calculations on a novel 2-cis olefin linker design indicate that it could permit simultaneous E-base hydrogen bonding with the thymine 4-oxo group, circumvention and solvent screening of the thymine 5-methyl group, and maintenance of triplex intra-stand base stacking interactions.

Biosynthesis of (MWCNTs)-COOH/CdO hybrid as an effective catalyst in the synthesis of pyrimidine-thione derivatives by water lily flower extract

Pink Water lily flower, with the scientific name of Nymphaea alba in the family of Nymphaeaceae, was collected from North of Iran, Mazandaran in spring, dried in shade and powdered. The powdered flower material was extracted in 70% (vol/vol) ethanol. Acid functionalized multi-walled carbon nanotubes/CdO (MWCNTs-COOH/CdO) was fabricated by using the Water lily flower extract. The presence of CdO nanoparticles and their surface conjugation to MWCNT have been confirmed by FT-IR, X-ray diffraction, transmission electron microscopy, scanning electron microscopy and energy-dispersive X-ray spectroscopy. It was used as a highly efficient catalyst for the synthesis of some pyrazolo[3,4-d]pyrimidine and pyrido[2,3-d]pyrimidine derivatives. These compounds were synthesized by the reaction of some substituted pyrazole or pyridine, thiourea and I-2 in the presence of MWCNTs-COOH/CdO hybrid (5% mol) in warm water. The assigned structure was further established by CHN analyses, NMR and FT-IR spectra.

Site of Azido Substitution in the Sugar Moiety of Azidopyrimidine Nucleosides Influences the Reactivity of Aminyl Radicals Formed by Dissociative Electron Attachment

In this work, electron-induced site-specific formation of neutral pi-type aminyl radicals (RNH.) and their reactions with pyrimidine nucleoside analogs azidolabeled at various positions in the sugar moiety, e.g., at 2′-, 3′-, 4′-, and 5′- sites along with a model compound 3-azido-1-propanol (3AZPrOH), were investigated. Electron paramagnetic resonance (EPR) studies confirmed the site and mechanism of RNH center dot formation via dissociative electron attachment-mediated loss of N-2 and subsequent facile protonation from the solvent employing the N-15-labeled azido group, deuterations at specific sites in the sugar and base, and changing the solvent from H2O to D2O. Reactions of RNH center dot were investigated employing EPR by warming these samples from 77 K to ca. 170 K. RNH center dot at a primary carbon site (5′-azido-2′,5′-dideoxyuridine, 3AZPrOH) facilely converted to a sigma-type iminyl radical (R=N center dot) via a bimolecular H-atom abstraction forming an alpha-azidoalkyl radical. RNH center dot when at a secondary carbon site (e.g., 2′-azido-2′-deoxyuridine) underwent bimolecular electrophilic addition to the C5=C6 double bond of a proximate pyrimidine base. Finally, RNH center dot at tertiary alkyl carbon (4′-azidocytidine) underwent little reaction. These results show the influence of the stereochemical and electronic environment on RNH center dot reactivity and allow the selection of those azidonucleosides that would be most effective in augmenting cellular radiation damage.

Tuning spin-crossover transition temperatures in non-symmetrical homoleptic meridional/facial [Fe(didentate)(3)](2+) complexes: what for and who cares about it?

The [FeN6] chromophores found in [Fe(didentate)(3)](2+) complexes, where didentate is a non-symmetrical 2-(6-membered-heterocyclic ring)-benzimidazole ligand (Lk), exist as mixtures of two geometrical mer (C-1-symmetry) and fac (C-3-symmetry) isomers. Specific alkyl-substituted six-membered heterocyclic rings connected to the benzimidazole unit (pyridines in ligands L1-L3, pyrazines in L4-L5 and pyrimidines in L6-L7) control the ligand field strength and the electron delocalization so that [Fe-II(Lk)(3)](2+) display tunable thermally-induced spin transitions in solution. Thermodynamic, spectroscopic (UV-Vis, NMR) and magnetic studies in solution demonstrate that [Fe(L6)(3)](2+) (L6 = 1-methyl-2-(pyrimidin-2-yl)-1H-benzo[d] imidazole) exhibits a close to room temperature spin transition (T-1/2 = 273(3) K) combined with a high stability formation constant (logo beta(Fe,L6)(1,3)) = 21.8(9) in acetonitrile), which makes this complex suitable for the potential modulation of lanthanide-based luminescence in polymetallic helicates. A novel method is proposed for assigning specific thermodynamic spin crossover parameters to fac-[Fe(L6)(3)](2+) and mer-[Fe (L6)(3)](2+) isomers in solution. The observed difference relies mainly on the entropic content Delta S-SCO(mer) – Delta S-SCO(fac) = 11(1) J mol(-1) K-1, which favors the spin transition for the meridional isomer. Intermolecular interactions occurring in the crystalline state largely overcome minor thermodynamic trends operating in diluted solutions and a single configurational isomer is usually observed in the solid state. Among the thirteen solved crystal structures 1-13 containing the [M(Lk)(3)](2+) cations (M = Fe, Ni, Zn, Lk = L6-L7), pure meridional isomers are observed six times, pure facial isomers also six times and a mixture (44% mer and 56% fac) is detected only once. Solid-state magnetic data recorded for the Fe-II complexes show the operation of slightly cooperative spin transitions in 7 (fac-[Fe(L6)(3)](2+)) and 12 (mer-[Fe(L7)(3)](2+)). For the meridional isomer in 6, a two-step spin state transition curve, associated with two phase transitions, is detected.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 274693-26-4, you can contact me at any time and look forward to more communication. SDS of cas: 274693-26-4.

Discovery of a Pyrimidinedione Derivative with Potent Inhibitory Activity against Mycobacterium tuberculosis Ketol-Acid Reductoisomerase

New drugs aimed at novel targets are urgently needed to combat the increasing rate of drug-resistant tuberculosis (TB). Herein, the National Cancer Institute Developmental Therapeutic Program (NCI-DTP) chemical library was screened against a promising new target, ketol-acid reductoisomerase (KARI), the second enzyme in the branched-chain amino acid (BCAA) biosynthesis pathway. From this library, 6-hydroxy-2-methylthiazolo[4,5-d]pyrimidine-5,7(4H,6H)-dione (NSC116565) was identified as a potent time-dependent inhibitor of Mycobacterium tuberculosis (Mt) KARI with a K-i of 95.4 nm. Isothermal titration calorimetry studies showed that this inhibitor bound to MtKARI in the presence and absence of the cofactor, nicotinamide adenine dinucleotide phosphate (NADPH), which was confirmed by crystal structures of the compound in complex with closely related Staphylococcus aureus KARI. It is also shown that NSC116565 inhibits the growth of H37Ra and H37Rv strains of Mt with MIC50 values of 2.93 and 6.06 mu m, respectively. These results further validate KARI as a TB drug target and show that NSC116565 is a promising lead for anti-TB drug development.

Does nocturnal activity prolong gecko longevity?

The majority of lizard clades are ancestrally and predominantly diurnal. The only major taxon in which most species are nocturnal is the Gekkota (geckos and pygopodids). As ectothermic thermoregulators, lizard metabolic rates are highly temperature dependent, and diurnal lizards therefore demonstrate higher metabolic rates than nocturnal ones. Furthermore, exposure to solar radiation is thought to reduce ectothermic longevity by increasing both metabolic costs and the rate of accumulating harmful mutations through UV radiation (UVC specifically). In being nocturnal, ectothermic species may reduce their intrinsic mortality rates and thus live longer. To test this hypothesis, we collected literature data on the maximum longevities of 740 lizard species, of which 185 are geckos. We examined whether geckos live longer than other lizards, and whether activity time affects gecko longevity. While geckos live relatively long for lizards of their size, their activity time was found to be unrelated to longevity, contradicting our predictions. We suggest that diurnal species may have evolved higher resistance to UV radiation via thicker, more keratinized skin. Elevated metabolic rates do not automatically equate with faster aging. Mortality through extrinsic causes (e.g., predation) may impose much stronger selective pressures than intrinsic causes.

Novel potent and selective pyrazolylpyrimidine-based SYK inhibitors

Hybridisation of amino-pyrimidine based SYK inhibitors (e.g. 1a) with previously reported diamine-based SYK inhibitors (e.g. TAK-659) led to the identification and optimisation of a novel pyrimidine-based series of potent and selective SYK inhibitors, where the original aminomethylene group was replaced by a 3,4-diaminotetrahydropyran group. The initial compound 5 achieved excellent SYK potency. However, it suffered from poor permeability and modest kinase selectivity. Further modifications of the 3,4-diaminotetrahydropyran group were identified and the interactions of those groups with Asp512 were characterised by protein X-ray crystallography. Further optimisation of this series saw mixed results where permeability and kinase selectivity were increased and oral bioavailability was achieved in the series, but at the expense of potent hERG inhibition.
