Abstract: The invention relates to a compound of formula (I) or a salt thereof: wherein: R1 is Et, n-Pr, i-Pr, C2fluoroalkyl, or —CH2CH2OH; R2 is H, Me, Et, n-Pr, i-Pr, C1-2fluoroalkyl, cyclopropyl or (cyclopropyl)methyl-; and NHR3 has the sub-formula (nhr3): wherein R3a is methyl or ethyl; R3b is H, methyl or ethyl; R3c is H, methyl or ethyl, R3d is H, methyl or ethyl, and R3e is H or methyl, provided that: (a) R3b is methyl or ethyl; and/or (b) R3c and R3d are independently methyl or ethyl; and provided that: (c) when R3c is ethyl and/or when R3d is ethyl and/or when R3e is methyl, then: R3a is methyl and/or R3b is hydrogen or methyl. These compounds are PDE4 inhibitors.

Abstract: There are provided according to the invention novel compounds of formula (I)

Abstract: There are provided according to the invention novel compounds of formula (I) and pharmaceutically acceptable salts and solvates thereof: wherein R1 is selected from the group consisting of C1-4alkyl, C4-6cycloalkyl(CH2)m—, methoxyC2-4alkyl, HOCH2CH2—, R3(O)2S(CH2)2—, R5R4NCO(CH2)n—, and heterocyclyl(CH2)m— wherein any nitrogen heteroatom of the heterocyclyl radical may be unsubstituted or substituted by methyl; R2 is hydrogen or methyl; R3 is methyl or NH2; R4-5 independently represent methyl, m is 0, 1 or 2; and n is 1 or 2; or R1 and R2 together with the nitrogen atom to which they are attached may form a heterocyclyl ring, which may be unsubstituted or substituted by one or two substituents selected from the group consisting of; methyl, ?O and (CH3)2N—.

Abstract: The invention provides a compound of formula (I) or a salt thereof: wherein Ar has the sub-formula (x) or (z): and wherein R3 is optionally substituted C3-8cycloalkyl, optionally substituted C5-7cycloalkenyl, an optionally substituted heterocyclic group (aa), (bb) or (cc), or a bicyclic group (ee); and wherein R4 is H, C1-3alkyl, C1-2fluoroalkyl, cyclopropyl, —CH2OR4a, —CH(Me)OR4a, or —CH2CH2OR4a; and R5 is inter alia H, C1-8alkyl, C1-3fluoroalkyl, C3-8cycloalkyl, certain substituted alkyl groups, —(CH2)n13-Het, or optionally substituted phenyl or —CH2-Ph; or R4 and R5 taken together are —(CH2)p1— or —(CH2)p3—X5—(CH2)p4—; provided that at least one of R4 and R5 is not a hydrogen atom (H). The invention also provides the use of the compounds as inhibitors of phosphodiesterase type IV (PDE4) and/or for the treatment and/or prophylaxis of inflammatory and/or allergic diseases such as chronic obstructive pulmonary disease (COPD), asthma, rheumatoid arthritis, allergic rhinitis or atopic dermatitis.
