Hypothesis

Can PPI-2458, a selective inhibitor of MetAP-2, reduce the severity of collagen-induced arthritis in mice?

Conclusion

PPI-2458 significantly reduces the severity of arthritis and joint destruction in both acute and chronic models of collagen-induced arthritis.

Supporting Evidence

  • PPI-2458 reduced clinical signs of arthritis in both acute and chronic CIA models.
  • The reduction in arthritis was associated with decreased joint inflammation and destruction.
  • PPI-2458 inhibited human endothelial cell proliferation and angiogenesis in vitro.

Takeaway

This study found that a drug called PPI-2458 can help make sick mice with arthritis feel better by stopping their bodies from making too many new blood vessels.

Methodology

The study used two models of collagen-induced arthritis in mice to assess the effects of PPI-2458 on disease severity and joint destruction.

Participant Demographics

10-week-old male DBA/1 mice were used for acute CIA and 8-week-old male DBA/1 mice for chronic CIA.
