Patent ID: 7115589

Claim:
A compound of formula (Ia) (or a salt or ester, or salt of an ester, thereof): wherein R A is Mx-aryl or Mx-heterocycle where M is a substituted or unsubstituted methylene, x is an integer from 1 to 6, the aryl moiety may bear one or more substituents, and the heterocycle is a substituted or unsubstituted, aromatic or nonaromatic heterocyclic moiety comprising a 5- to 7-membered ring bearing one or more heteroatoms; R B comprises an aryl, or heteroaryl moiety bearing at least one a substituent of Series llb: R C is hydrogen, halogen, an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, or —ZR, wherein Z is —O—, —S—, or NR, wherein each occurrence of R without a further alphanumeric superscript is independently hydrogen, or a substituted or unsubstituted aliphatic, heteroaliphatic, aryl, or heteroaryl moiety; each occurrence of K is independently —O— or —S—; each occurrence of Y is independently —O—, —S—, —NR— or a chemical bond; each occurrence of R (without a further alphanumeric superscript) is independently hydrogen, or a substituted or unsubstituted aliphatic, heteroaliphatic, aryl, or heteroaryl moiety; each occurrence of R 1 is independently a substituted or unsubstituted aliphatic, heteroaliphatic, aryl, or heteroaryl moiety, or, except in YR 1 moieties in which Y is a covalent bond, R 1 may also be H; each occurrence of R 2 is independently R 1 , —PK(YR 1 )(YR 1 ), —SO 2 (YR 1 ) or —C(O)(YR 1 ); each occurrence of R 6 independently represents an aliphatic, heteroaliphatic, aryl, or heteroaryl moiety; each occurrence of G is independently —O—, —S—, —NR— or M x ; and, each occurrence of M Y is independently a methine group or a lower alkyl moiety which contains a methine group and optionally may be further substituted, wherein in each of the foregoing groups each aliphatic or heteroaliphatic moiety may be branched or unbranched, cyclic or acyclic and substituted or unsubstituted, and each aryl and heteroaryl moiety may be substituted or unsubstituted.
