摘要:
Synthetic enzymes that mimic the catalytic activity of naturally occurring enzymes by providing catalytic sites enclosed in cages that protect the sites from undesirable molecules and attract and permit entry of the relevant substrates are disclosed. Molecules that mimics the catalytic activity of superoxide dismutase and catalase, pharmaceutical compositions containing these molecules, and methods for using these compositions are also disclosed.
