SB-3CT

SB-3CT is a potent matrix metalloproteinase MMP-2 and MMP-9 inhibitor. SB-3CT is a 2-[(arylsulfonyl)methyl]thiirane that achieves potent inhibition, by a thiirane-opening mechanism, of the MMP2 and MMP9 zinc metalloproteases. SB-3CT attenuates behavioral impairments and hippocampal loss after traumatic brain injury in rat. 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.

How to use

In Vitro:

SB-3CT has shown efficacy in an animal model of severe traumatic brain injury (TBI). SB-3CT inhibits MMP-9 with an inhibition constant Ki of 400±15 nM. Inhibition of PC3 tumor growth by SB-3CT could also be a direct consequence of reduced extracellular matrix degradation within the bone tissue by the tumor cells themselves and/or by osteoclasts. Indeed, SB-3CT treatment is associated with a reduced osteolytic response, indicating that SB-3CT helps to preserve bone integrity.

In Vivo:

SB-3CT (i.p.; 50 mg/kg; every other day; five weeks) inhibits intraosseous growth of human PC3 cells within the marrow of human fetal femur fragments previously implanted in SCID mice.
