摘要:
Compound of formula I: ** Formula ** or a salt or ester thereof; wherein: A is - (C (R4) 2) n- in which any one C (R4) 2 of said - (C (R4) 2) n- may be optionally replaced with -O-, -S- , -S (O) p-, NH or NRa; n is 3, 4, 5 or 6; each p is 1 or 2; Ar is a C2-C20 heterocyclyl group or a C6-C20 aryl group, in which the C2-C20 heterocyclyl group or the C6-C20 aryl group is optionally substituted with 1, 2, 3, 4 or R6; Each R3, R4 or R6 is independently H, oxo, OR11, NR11R12, NR11C (O) R11, NR11C (O) OR11, NR11 (O) NR11R12, N3, CN, NO2, SR11, S (O) pRa, NR11S ( O) pRa, -C (>; = O) R11, -C (>; = O) OR11, -C (>; = O) NR11R12, -C (>; = O) SR11, -S (O) p (OR11), -SO2NR11R12, -NR11S (O) p (OR11), -NR11SOpNR11R12, NR11C (>; = NR11) NR11R12, halogen, (C1-C8) alkyl, alkenyl (C2-C8), alkynyl (C2-C8), arylalkyl (C1 -C8), C6-C20 aryl, C2-C20 heterocyclyl, (C3-C7) cycloalkyl or carbocyclylalkyl (C4-C8) alkyl; or two R4 in adjacent carbon atoms, when taken together, can optionally form a double bond between the two carbons to which they are attached or can form a cycloalkyl ring (C3-C7) in which a carbon atom of said cycloalkyl ring (C3-C7) may be optionally replaced with -O-, -S-, -S (O) p-, -NH- or -NRa-; or four R4 in adjacent carbon atoms, when taken together, can optionally form an optionally substituted C6 aryl ring; or two R4 on the same carbon atom, when taken together, can optionally form a cycloalkyl ring (C3-C7) in which a carbon atom of said cycloalkyl ring (C3-C7) can be optionally replaced with - O-, -S-, -S (O) p-, -NH- or NRa-; or two R6 in adjacent carbon atoms, when taken together, can optionally form a cycloalkyl ring (C3-C7) in which a carbon atom of said cycloalkyl ring (C3-C7) can be optionally replaced with -O -, -S-, -S (O) p-, -NH- or -NRa-; each Ra is independently (C1-C8) alkyl, halo (C1-C8) alkyl, (C2-C8) alkenyl, (C2-C8) alkynyl, (C1-C8) arylalkyl, C6-C20 aryl, C2-C20 heterocyclyl, cycloalkyl (C3-C7) or carbocyclylalkyl (C4-C8) alkyl in which an
