This invention provides a cytosine analogue, a method of preparation of a cytosine analogue, a DNA rhethyltransferase 1 inhibitor, a method for DNA methylation inhibition, the use of the analogue in the treatment of diseases associated with deviations from normal DNA methylation. More precisely, the invention relates to various derivatives of cytosine, as well as methods of preparation of mono- and multi- 1,4,5 and 6-substituted cytosines. In general, the solution relates to providing effective modulators of DNA methylation which could be used in prevention and treatment of diseases associated with DNA methylation level disorders.

The subject matters of the invention are: a crystallographic model of the binding site and a modulator regulating the catalytic activity of phosphofructokinase (PFK), a method of designing, selecting and producing a PFK modulator, a computer-based method for the analysis of the interaction between the modulator and PFK, a computer-based method the analysis of molecular structures, a method of assessing the ability of the potential modulator to interact in the binding site on the PFK surface, a method of providing data for generating structures and/or performing design for ligands binding PFK, PFK homologues or analogues, complexes of PFK with a potential modulator, or complexes of PFK homologues or analogues with potential modulators, a computer system. The invention makes it possible to design a suitable activator, which could be used to modulate PFK activity, taking advantage of PFKs capability to bind in its effector site phosphate groups or other groups with a similar potential to interact, which correspond with the substituents in positions 1, 2 and 6 of the fructose ring, or groups corresponding with positions of the fructose ring groups interacting in the PFK effector site.

The subjects of the present invention are the method of preparation of 4-furfurylcytosine and/or its derivatives, its use in the manufacture of anti-aging compositions and an anti- aging composition. As 4-furfurylcytosine and/or its derivatives possesses a series of biological properties it might be use as a composition having excellent anti-aging effect to prevent the sagging of skin and loss of luster and to improve sufficiently its aesthetic appearance without significantly change the growth rate and the total growth ability of the skin. Optimal methods of manufacturing this compound, while at the same time obtaining the highest possible process efficiency, with particular emphasis on its utility in the pharmaceutical and cosmetic industries are presented.
摘要:
The subject of the invention is a modified gene of human activation-induced cytidine deaminase (AID), a method of modification of human AID gene, a composition showing AID activity, and a method of preparation of such composition. In particular, the invention concerns a modified gene of human AID for the production of an active enzyme in a bacterial system and use of the composition in the analyses of DNA/RNA amination/deamination and/or methylation/demethylatiori.
摘要:
The present invention relates to an RNA oligomer, methods for regulating ' a miRNA production process and RNA oligomers used as miRNA production process regulators. More precisely, the present invention relates to use of RNA oligomers disrupting a pre-miRNA structure as miRNA production process regulators. Oligomer interactions with a miRNA precursor (pre-miRNA) change the precursor' s secondary and tertiary structure. In consequence, the pre-miRNA is not specifically recognised and cleaved by the Dicer ribonuclease, and the specific miRNA is not produced.
