Abstract: The present invention relates to a polyribonucleotide including a hammerhead trans-ribozyme directed against a plant mitochondrial RNA and a structure in the form of tRNA that can be aminoacylated by valine, and to the use thereof in plants in particular for inducing cytoplasmic male sterility.

Abstract: A cytosine analog, a method of preparation of a cytosine analog, a DNA methyltransferase 1 inhibitor, and a method for DNA methylation inhibition, is provided for the treatment of diseases associated with deviations from normal DNA methylation. The analog of cytosine may be comprised of 1, N4, 5 and 6-substituted derivatives of cytosine or 5,6-dihydrocytosine, wherein the analog can be described by the chemical formula where R1 is H, R3, R4, 2?-deoxyribosyl, R4 is alkyl or aryl, X is N or C, wherein if X in the analog of formula I is N, then R5 is no substituent and if X in the analog of formula I and/or II is C or if X in the analog of formula II is N, then R5 and R6 are independently alkyl, aryl, hydroxyalkyl, aminoalkyl, hydroxyl, carboxyl, amino group, alkoxyl, aryloxyl, aminoalkyl, aminoaryl, thio group, sulfonyl, sulfinyl or halogen.

Abstract: The invention relates to the use of an L-ribozyme, which is capable of splitting an L-RNA in the region of a target sequence of the L-RNA, in order to produce a pharmaceutical composition for trating undesired physiological adverse reactions due to the administration of a therapeautic modecule containing the L-RNA. Alternatively, an endogeneous target RNA may also be split by the L-ribozyme.

Abstract: The subject matters of this invention are a sequence of double-stranded RNA: ATN-RNA, intervention using interference RNA (iRNAi), use of a sequence of double-stranded RNA: ATN-RNA, a method of treating a brain tumor and a method of inhibiting a brain tumor cells which express tenascin, a kit for inhibiting cancer cell which expresses tenascin and a method for a kit preparation in a brain tumor therapy. Malignant gliomas preferentially express a number of surface markers that may be exploited as therapeutic targets, including tenascin-C, an extracellular matrix glycoprotein that is ubiquitously expressed by malignant gliomas and probably contributes to tumor cell adhesion, invasion, migration and proliferation. For tenascin-C inhibition, RNA interference intervention (iRNAi) approach have been applied.

Abstract: 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.

Abstract: 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.
