Patent ID: 7704924

Claim:
A collection of compounds all of which are represented by formula II: wherein: A is O, S, NH, or a single bond; R 2 and R 3 are independently selected from: H, R, OH, OR, ═O, ═CH—R, ═CH 2 , CH 2 —CO 2 R, CH 2 —CO 2 H, CH 2 —SO 2 R, O—SO 2 R, CO 2 R, COR, CN and there is optionally a double bond between C2 and C3; R 6 , R 7 , and R 9 are independently selected from H, R, OH, OR, halo, nitro, amino, Me 3 Sn; where R is an alkyl group having 1 to 10 carbon atoms, or an aralkyl group of up to 12 carbon atoms whereof the alkyl group optionally contains one or more carbon-carbon double or triple bonds, which may form part of a conjugated system, or an aryl group of up to 12 carbon atoms; and is optionally substituted by one or more halo, hydroxy, amino, or nitro groups, and optionally contains one or more hetero atoms which may form part of, or be, a functional group; Y is a divalent group such that HY═R; X′ is CO, NH, S or O; T is an amino acid residue combinatorial unit, where each T may be different if n is greater than 1; and n is a positive integer from 1 to 16.
