RG3039 Chemical Properties, Uses, Production
Uses
RG3039 (PF-06687859) is an orally bioavailable and brain-penetrant DcpS inhibitor with an IC50 of 0.069 nM.
Biological Activity
RG3039 is a brain-penetrant and potent inhibitor against the scavenger mRNA-decapping enzyme DcpS (m7GpppX diphosphatase) in vitro (mouse DcpS IC50 = 3.4 nM) and in mice in vivo (∼90% & ∼80% inhibition of brain DcpS, respectively, 2 h & 72 h post last 3 mg/kg daily ip. from P1 to P10). In a murine severe spinal muscular atrophy (SMA) model, RG3039 (10-20 mg/kg/d ip. from P1 till death) increases SMAΔ7 mice survival (by 26%) and motor function with a ∼50% increase of VGLUT1 synapses number on L3-L5 motor neurons (33.7/WT mice at P13 vs. 17.2/SMA mice without 26.1/SMA mice with RG3039 treatment).
in vivo
RG3039 can extend survival and improve function in two SMA mouse models of varying disease severity (Taiwanese 5058 Hemi and 2B/ SMA mice), and positively impacts neuromuscular pathologies. In 2B/ SMA mice, RG3039 provides a >600% survival benefit (median 18 days to >112 days) when dosing began at P4, highlighting the importance of early intervention[2]. RG3039 distributes to central nervous system tissues where it robustly inhibits DcpS enzyme activity, but minimally activates SMN expression or the assembly of small nuclear ribonucleoproteins. RG3039 treated SMA mice shows a dose-dependent increase in survival, weight and motor function and it is associated with improved motor neuron somal and neuromuscular junction synaptic innervation and function and increased muscle size. RG3039 also enhances survival of conditional SMA mice[3].
