HALOFUGINONE LACTATE

HALOFUGINONE LACTATE is a halogenated derivative of febrifugine, a natural quinazolinone-containing compound found in the Chinese herb D. febrifuga.Halofuginone inhibits prolyl-tRNA synthetase in an ATP-dependent manner with a Ki of 18.3 nM. Halofuginone is a specific inhibitor of type-I collagen synthesis and attenuates osteoarthritis (OA) by inhibition of TGF-β activityhalofuginone (HF), a widely studied derivative of febrifugine, inhibits the development of T (H) 17-driven autoimmunity in a mouse model of multiple sclerosis by activating the amino acid response (AAR) pathway. HF binds glutamyl-prolyl-tRNA synthetase (EPRS), inhibiting prolyl-tRNA synthetase activity; this inhibition is reversed by the addition of exogenous proline or EPRS.
