Web4. máj 2012 · The hydrolysis of N-methyl O-phenyl sulfamate (1) has been studied as a model for steroid sulfatase inhibitors such as Coumate, 667 Coumate, and EMATE. At neutral pH, simulating physiological conditions, hydrolysis of 1 involves an intramolecular proton transfer from nitrogen to the bridging oxygen atom of the leaving group. …
WebThe sulfamate functional group, which is mainly responsible for the inactivation of the enzyme, binds in the enzyme catalytic region close to the formylglycine residue coordinated to the Ca2+ion (not shown) by a H-bond network. Web6. máj 2002 · The consequence of the conclusion from our earlier study is, therefore, that if the hydrolysis of the sulfamic moiety (step 1, Fig. 2) occurs prior to the irreversible inhibiting step (step 2, Fig. 2), then the phenyl sulfamate based compounds should possess good inhibitory activity whilst the alkyl sulfamates would be expected to lack inhibitory activity …
