A method of measuring α-methylacyl-CoA racemase (AMACR) activity in a sample is described comprising the steps of: (i) providing a sample; (ii) contacting said sample with a substrate compound that undergoes elimination of hydrogen and a leaving group catalysed by said AMACR to produce a product compound having an additional carbon-carbon double bond; and (iii) measuring the amount of said leaving group and/or of said product compound and/or of unreacted substrate compound. Also provided are methods of diagnosis and medical imaging, in particular for use in diagnosing prostate cancer. Also provided are substrate compounds of Formula 1 for use in the methods described herein.

Disclosed herein are hardeners for use in making cleavable epoxy compositions, including compositions wherein components in contact with epoxy composition can be recovered, as well as methods of making such hardeners.
Prodrugs of analogs of the anti-tumor antibiotic CC-1065 having a cleavable protective group containing a sulfonic acid containing phenyl carbamate, in which the protecting group confers enhanced water solubility upon the prodrug, and in which the prodrug also has a moiety, such as a sulfide or a disulfide, that can conjugate to a cell binding reagent such as an antibody. The therapeutic use of such prodrug conjugates is also described; such prodrugs of cytotoxic agents have therapeutic use because they can deliver cytotoxic prodrugs to a specific cell population for enzymatic conversion to cytoxic drugs in a targeted fashion.
The present invention provides prodrugs of analogs of the anti-tumor antibiotic CC-1065 having a cleavable protective group containing a sulfonic acid containing phenyl carbamate, in which the protecting group confers enhanced water solubility upon the prodrug, and in which the prodrug also has a moiety, such as a sulfide or a disulfide, that can conjugate to a cell binding reagent such as an antibody, and for the therapeutic use of such prodrug and conjugates, and for processes for preparing such prodrugs and conjugates.
