Antagonists Peptide , cyclic polypeptide drugs , Topoisomerase , pharmaceutical compositions , Highly Potent and Stable Capped siRNAs , nucleotide prodrugs , carbonic anhydrase II Activity , Glycosaminoglycan and phospholipids . Secondly, maleimides, particularly the bismaleimides are used for synthesis of self-healing polymers , selfassembled functional telechelics and modular block copolymers , reactive and functional polymers such as click chemistry . Maleimide derivatives are also used in chemicals applications such as dienophiles in cycloaddition reactions , Thia Paterno Buchi Reaction C-H activation and functionalized basic maleimides are few of them.
