摘要:
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.
摘要:
The invention relates to a compound of formula (I) or a salt thereof: wherein: R1 is C1-4alkyl, C1-3fluoroalkyl or —(CH2)2OH; R2 is a hydrogen atom (H), methyl or C1fluoroalkyl; R3a is a hydrogen atom (H) or C1-3alkyl; R3 is optionally substituted branched C3-6alkyl, optionally substituted C3-8cycloalkyl, optionally substituted mono-unsaturated-C5-7cycloalkenyl, optionally substituted phenyl, or an optionally substituted heterocyclic group of sub-formula (aa), (bb) or (cc): in which n1 and n2 independently are 1 or 2; and Y is O, S, SO2, or NR4; and wherein Het is of sub-formula (i), (ii), (iii), (iv) or (v): The compounds are phosphodiesterase (PDE) inhibitors, in particular PDE4 inhibitors. Also provided is the use of a compound of formula (I), or a pharmaceutically acceptable salt thereof, in the manufacture of a medicament for the treatment and/or prophylaxis of an inflammatory and/or allergic disease in a mammal such as a human, for example chronic obstructive pulmonary disease (COPD), asthma, or allergic rhinitis.
