Lipid-conjugated monovalent and bivalent secondary mitochondria derived activator of caspases (Smac) derivatives were synthesized and examined for in vitro and in vivo anticancer activity. Methods for treating cancer with these compounds are also disclosed.
The present invention relates to detecting cleavage activity of an enzyme. The various aspects of the invention include an enzyme detection device, kit, method and use for detecting or measuring the presence in a test sample of the activity of an enzyme capable of cleaving a substrate. The invention also relates to indicator and binding molecules useful for carrying out the invention. The enzyme substrate contains a hidden binding site which is only revealed upon cleavage by the enzyme.
