Claim:
A compound of formula wherein R, R 1 , R 2 , R 3 , R 4 , R 5 and R 6 each independently are: R═H, an alkyl, wherein the alkyl is a straight or branched hydrocarbon chain having from 1 to 25 of carbon atoms, an aryl, wherein the aryl is a substituted benzene ring, system fused to one or more substituted benzene ring an aryl alkyl, a heterocycle, wherein the heterocycle is a three to twelve-membered heterocyclic ring optionally possessing one or more degrees of unsaturation, and containing one or more heteroatomic substitutions selected from the group consisting of —S—, —SO—, —SO 2 —, —O—, or —N—, a substitution of the alkyl, wherein one or more carbon atoms of the straight or branched hydrocarbon chain are substituted with a substituent selected from the group consisting of alkoxy, alkylsulfanyl, alkylsulfenyl, alkylsulfonyl, oxo, hydroxy, mercapto, amino optionally substituted by alkyl, carboxy, carbamoyl optionally substituted by alkyl, aminosulfonyl optionally substituted by alkyl, silyloxy optionally substituted by alkoxy, alkyl, or aryl, silyl optionally substituted by alkoxy, alkyl, or aryl, nitro, cyano, halogen, and perfluoroalkyl; a substitution of the aryl, wherein one or more carbon atoms of the one or more substituted benzene ring are substituted with a substituent selected from the group consisting of alkyl, alkoxy, alkylsulfanyl, alkylsulfenyl, alkylsulfonyl, oxo, hydroxy, mercapto, amino optionally substituted by alkyl, carboxy, tetrazolyl, carbamoyl optionally substituted by alkyl, aminosulfonyl optionally substituted by alkyl, acyl, aroyl, heteroaroyl, acyloxy, aroyloxy, heteroaroyloxy, alkoxycarbonyl, silyloxy optionally substituted by alkoxy, alkyl, or aryl, silyl optionally substituted by alkoxy, alkyl, or aryl, nitro, cyano, halogen, and perfluoroalkyl; and a substitution of the heterocycle, wherein one or more carbon atoms of the heterocyclic ring are substituted with a substituent selected from the group consisting of alkyl, alkoxy, alkylsulfanyl, alkylsulfenyl, alkylsulfonyl, oxo, hydroxy, mercapto, amino optionally substituted by alkyl, carboxy, carbamoyl optionally substituted by alkyl, aminosulfonyl optionally substituted by alkyl, nitro, cyano, halogen, and perfluoroalkyl; where R 7 ═H, an electron donating group, or an electron withdrawing group at some or all the positions on the aromatic ring; R 2 , R 3 , R 4 , and R 5 are each independently H, an electron donating group, or an electron withdrawing group at some or all the positions on the aromatic ring, wherein the electron donating group is selected from the group consisting of an alkyl group, an alcohol group, an alkoxy group, an amino group, and a phenolic group, and wherein the electron withdrawing group is selected from the group consisting of a halogen, a nitrile, a carboxylic acid, a carbonyl, a carboxylic group, and an aldehyde; R 6 is H, a phosphate or amino acid ester(s) or salt(s) thereof; and where “*” represents a chiral center.
