Synthesis and potency of novel uracil nucleotides and derivatives as P2Y2 and P2Y6 receptor agonists
摘要:
The phosphate, uracil, and ribose moieties of uracil nucleotides were varied structurally for evaluation of agonist activity at the human P2Y(2), P2Y(4), and P2Y(6) receptors. The 2-thio modi. cation, found previously to enhance P2Y2 receptor potency, could be combined with other favorable modi. cations to produce novel molecules that exhibit high potencies and receptor selectivities. Phosphonomethylene bridges introduced for stability in analogues of UDP, UTP, and uracil dinucleotides markedly reduced potency. Truncation of dinucleotide agonists of the P2Y(2) receptor, in the form of Up(4)-sugars, indicated that a terminal uracil ring is not essential for moderate potency at this receptor and that specific SAR patterns are observed at this distal end of the molecule. Key compounds reported in this study include 9, alpha, beta-methylene-UDP, a P2Y(6) receptor agonist; 30, Up(4)-phenyl ester and 34, Up(4)-[1] glucose, selective P2Y(2) receptor agonists; dihalomethylene phosphonate analogues 16 and 41, selective P2Y(2) receptor agonists; 43, the 2-thio analogue of INS37217 (P-1-(uridine-5')-P-4-(2'-deoxycytidine-5') tetraphosphate), a potent and selective P2Y(2) receptor agonist.

公开(公告)日:2003-08-28
An antisense molecule which acts on both directions of the inhibition and expression of a gene function and is capable of on-off switching of a gene function appropriately depending on the external factors (orientation controlling factors); and a method for reversibly controlling the expression of a gene function by using the antisense molecule. Such an antisense molecule, which has at least one sugar-base moiety consisting of sugar and a purine or pyrimidine base bonded thereto via a glucoside bond, can bind to a mRNA/gene and/or dissociate therefrom under the orientation control of the base moiety in the molecule by the orientation controlling factors.

The present invention relates to a population of nucleic acids, said population comprising a first population of nucleic acids of the same length, said length being in the range of 5-15 nucleotides or units, said first population representing at least 1% of the possible different nucleic acid sequences for nucleic acids of said length, at least one nucleic acid in the first population being an LNA (Locked Nucleoside Analogues) oligomer. The population of oligonucleotides is preferably bonded to a solid support. The pluralities of nucleic acids are particularly useful in methods relating to the capture of target nucleic acids, or as probes, e.g. PCR probes. The invention also features LNA oligomers wherein the LNA units have SBC (Selective Binding Complementary) nucleobases.
