[EN] INTEGRIN TARGETING LIGANDS FOR OCULAR DELIVERY OF RNAI COMPOUNDS [FR] LIGANDS CIBLANT L'INTÉGRINE POUR L'ADMINISTRATION OCULAIRE DE COMPOSÉS D'ARNI
摘要:
The disclosure relates to RNA agents modified for targeted delivery to the eye. The present invention provides modified double stranded ribonucleic acid (dsRNAi) agents conjugated to an integrin targeting ligand, as well as methods of modulating the expression of a target gene in an ocular cell or tissue and methods of treating subjects having an ocular disease or disorder using such dsRNAi agents.
The present invention relates to novel human insulin derivatives which are soluble at physiological pH values and have a prolonged profile of action. The invention also relates to methods of providing such derivatives, to pharmaceutical compositions containing them, to methods of treating diabetes and hyperglycaemia using the insulin derivatives of the invention and to the use of such insulin derivatives in the treatment of diabetes and hyperglycaemia.
The present invention is related to insulin derivatives having a side chain attached either to the α-amino group of the N-terminal amino acid residue of B chain or to an ε-amino group of a Lys residue present in the B chain of the parent insulin molecule via an amide bond which side chain comprises one or more residues of ethyleneglycol, propyleneglycol and/or butyleneglycol containing independently at each termini a group selected from —NH
2
and —COOH; a fatty diacid moiety with 4 to 22 carbon atoms, at least one free carboxylic acid group or a group which is negatively charged at neutral pH; and possible linkers which link the individual components in the side chain together via amide or ether bonds, said linkers optionally comprising a free carboxylic acid group.

protein levels of all three PIM isoforms (PIM1/2/3), and this can promote resistance to PIM inhibitors and chemotherapy. To overcome this effect, we designed PIM proteolysis targeting chimeras (PROTACs) to target PIM for degradation. PIM PROTACs effectively downmodulated PIM levels through the ubiquitin-proteasome pathway. Importantly, degradation of PIM kinases was more potent than inhibition of catalytic
