Biological Activity for Halofuginone hydrobromide

Halofuginone hydrobromide is a high affinity competitive prolyl-tRNA synthetase inhibitor (K_i = 18.3 nM). Blocks expression of MMP2. Inhibits ECM invasion in vitro and lung metastasis by bladder cancer cells in mice. Inhibits the development of Th17-driven autoimmunity in a mouse model of multiple sclerosis by activating the amino acid response (AAR) pathway. Also antiparasitic.
