A Novel Anti-Cancer/Anti-Proliferation and Anti-Migration Compound—An Inhibitor to Dual Specificity Phosphatase Slingshot-2
Highly specific SSH-2 inhibitor that regulates F-actin depolymerization.
New therapeutics, targeting actin filament dynamics and signaling pathways, for the treatment of cancer, Alzheimer’s, and other diseases.
Scientists at UC San Diego have found a family of small molecule inhibitors that specifically binds to SSH-2. These compounds represent the first inhibitors of a phosphatase that regulates the F-actin depolymerization.The inventors used a molecular docking simulation software (DOCK 6.0) to virtually screen open-source chemical databases and determined the binding affinities to 18 of DSPs with known three-dimensional structures as determined by x-ray crystallography, including SSH-2, VHR (DUSP3), VHY (DUSP15), VHZ (DUSP23), VH1 (DUSP12), VH3 (DUSP5), PTEN (phosphatase and tensin homolog), KAP (Cdk2 associated protein phosphatase), MKP3 (rVH6, Pyst1), MKP4, MKP5, MTMR2, DUSP18, PRL3, CDC14b, Pac-1, Jsp-1, and TMPD. Five compounds with similar chemical structures have the highest affinity for SSH-2, but lowest affinity for the other DSPs, among the best 100 SSH-2 binding compounds. Figure 1.
