Uses
SB 3CT is a selective and potent gelatinase inhibitor which may be used for the treatment of brain metastasis.
Uses
SB?3CT has been used as irreversible inhibitor of matrix metallopeptidase 9 (MMP9) in cell cultures to exclude reciprocal regulation.
Definition
ChEBI: 2-[(4-phenoxyphenyl)sulfonylmethyl]thiirane is an aromatic ether.
Biochem/physiol Actions
SB-3CT is a potent matrix metalloproteinase MMP-2 and MMP-9 inhibitor. Matrix metalloproteinases (MMPs) are involved in a number of activities including angiogenesis and embryogenesis. In particular, gelatinases A (MMP-2) and B (MMP-9), are thought to facilitate tumor metastasis. SB-3CT exhibits a covalent mechanism based behavior in inhibition of MMP-2 and MMP-9. This inhibitor appears to have similarity to TIMP-1 and TIMP-2 in the slow-binding component of inhibition. SB-3CT has been shown to directly bind to the zinc in the catalytic site of MMP-2. SB-3CT does not affect the activities of MMP-1 (Ki = 206 μM) MMP-3 (Ki = 15 μM), or MMP-7 (Ki = 96 μM).
