Wherein the bond marked * is linked to the ring containing Q, V and W through -[Linker1]- and the bond marked ** is linked to A through -[Linker2]-; A is an optionally substituted mono-, bi- or tri-cyclic carbocyclic or heterocyclic ring system; and -[Linker1]- and -[Linker2]- independently represent a bond, or a divalent linker radical.
Abstract:
Compounds of formula (IA) or (IB) are IKK inhibitors useful in the treatment of autoimmune and inflammatory diseases: wherein R7 is hydrogen or optionally substituted (C1-C6)alkyl; A is an optionally substituted aryl or heteroaryl of 5-13 ring atoms; Z is a radical of formula R1C(R2)(R3)NH—Y-L1-X1-(CH2)z— wherein R1 is a carboxylic acid group (—COOH), or an ester group which is hydrolysable by one or more intracellular esterase enzymes to a carboxylic acid group; and R2 and R3 independently represent the side chain of a natural or non-natural alpha amino acid but neither of R2 and R3 is hydrogen, or R2 and R3 taken together with the carbon atom to which they are attached form a C3-C7 cycloalkyl ring, and z, Y, L1 and X1 are as defined in the claims.
Abstract:
Covalent conjugation of an alpha amino acid ester to a modulator of the activity of a target intracellular enzyme or receptor, wherein the ester group of the conjugate is hydrolysable by one or more intracellular carboxylesterase enzymes to the corresponding acid, leads to accumulation of the carboxylic acid hydrolysis product in the cell and enables improved or more prolonged enzyme or receptor modulation relative to the unconjugated modulator.
Abstract:
Compounds of formula (I) are inhibitors of p38 MAP kinase, and are therefore of utility in the treatment of, inter alia, inflammatory conditions including rheumatoid arthritis and COPD: wherein: G is —N═ or —CH═; D is an optionally substituted divalent mono- or bi-cyclic aryl or heteroaryl radical having 5-13 ring members; R6 is hydrogen or optionally substituted C1-C3 alkyl; P represents hydrogen and U represents a radical of formula (IA); or U represents hydrogen and P represents a radical of formula -A-(CH2), —X1-L1-Y—NH—CHR1R2 wherein A represents an optionally substituted divalent mono- or bicyclic carbocyclic or heterocyclic radical having 5-13 ring members; z, Y, L1, and X1 are as defined in the specification; R1 is a carboxylic acid group (—COOH), or an ester group which is hydrolysable by one or more intracellular esterase enzymes to a carboxylic acid group; and R2 is the side chain of a natural or non-natural alpha amino acid.
Abstract:
The present invention provides a compound of formula (I) or a pharmaceutically acceptable salt, N-oxide, hydrate or solvate thereof: wherein: ring A, R1, R2, n, X, V, W, Z, ring B, [Linker] and R areas defined herein.
