Patent ID: 8198218

Claim:
A combinatorial library comprising a plurality of compounds represented by the structure of formula I: wherein A and D are each CH 2 , B is C═O; X and Y together form a group represented by the formula: R 1a , R 1b , R 2a , R 2b , R 4a and R 4b are independently of each other hydrogen or a linear or branched chain alkyl; m and n are independently of each other an integer of 1-6; Q is Z is R 5a , R 5b , R 7a , R 7b , R 8 and R 9a are independently of each other hydrogen, a linear or branched chain alkyl, cycloalkyl, aryl, aralkyl, heterocyclyl, heteroaryl, acyl, carboxyalkyl, carboxyaryl, benzyl, hydroxybenzyl, benzyloxycarbonyl, a side chain of a natural or unnatural amino acid or a peptide; and L is hydrogen, OR 10 , or NHR 11 wherein R 10 and R 11 are independently of each other hydrogen, a linear or branched chain alkyl, a side chain of a natural or unnatural amino acid, a peptide or a solid support; such that the compound is represented by the structure or a pharmaceutically acceptable salt, hydrate or solvate thereof.
