Description
OverviewA cell-permeable racemic mixture of Halofuginone whose D-(+)/(2R, 3S) enantiomer serves as the active inhibitor against ProRS-mediated aminoacylation by simultaneously preventing ProRS-catalyzed Pro-AMP formation and the subsequent Pro transfer from Pro-AMP to tRNAPro. Proline, but not other NEAA, is able to reverse the inhibitory effect of HF in in vitro rabbit reticulocyte lysate translations (1 µM HF; 1 mM Pro) and prevent HF-induced cellular AAR pathway activation (100 nM HF/2 mM Pro/MEF; 10 nM HF/1 mM Pro/Murine CD4+ CD25- T cells). Shown to inhibit bFGF-induced neovascularization in a murine corneal angiogenesis model (5 mg/kg/d via food intake) and significantly reduce the severity of MOG33-55-induced EAE in mice (2 µg/mouse/d i.p.) in vivo. Unlike AA-AMP mimetics, HF does not compete against ATP for ProRS binding.

SynonymsSTENOROL, HF, Hydrobromide, prolyl-tRNA synthetase Inhibitor, trans-(±)-7-Bromo-6-chloro-3-[3-(3-hydroxy-2-piperidinyl)-2-oxopropyl]-4(3H)-quinazolinone hydrobromide
DescriptionA cell-permeable racemic mixture of Halofuginone, a halogenated derivative of the Dichroa febriguga alkaloid Febrifugine, whose D-(+)/(2R, 3S) enantiomer serves as the active inhibitor against ProRS- (prolyl-tRNA synthetase) mediated aminoacylation by simultaneously targeting/blocking ProRS Proline-binding pocket with its hydroxypiperidine and tRNA 3′ end adenosine-binding site with its halogenated 4-quinazolinone, preventing not only ProRS-catalyzed prolyl adenylation (Pro-AMP formation), but also the subsequent Pro transfer from Pro-AMP to tRNAPro. Consistently, only proline, but not other NEAA, is able to reverse the inhibitory effect of HF in in vitro rabbit reticulocyte lysate translations (1 µM HF; 1 mM Pro) and prevent HF-induced cellular AAR (amino acid response) pathway activation (100 nM HF/2 mM Pro/MEF; 10 nM HF/1 mM Pro/Murine CD4+ CD25- T cells). Shown to inhibit bFGF-induced neovascularization in a murine corneal angiogenesis model (5 mg/kg/day via food intake) and significantly reduce the severity of myelin antigen MOG33-55-induced autoimmune EAE/encephalomyelitis in mice (2 µg/mouse/day i.p.) in vivo. Unlike AA-AMP mimetics, HF does not compete against ATP for ProRS binding. ATP, in its ProRS bound state, actually helps stabilize HF via hydrogen bond interactions.
