AB-452 (AB452) is a potent, small molecule inhibitor of noncanonical poly(A) polymerases PAPD5 and PAPD7 (PAPD5/7), inhibits PAPD5/7 enzymatic activities, reduces HBsAg in vitro (EC50=1.4/6.8 nM).AB-452 demonstrated specific antiviral activity for HBV, was inactive against a panel of 10 different RNA and DNA viruses with EC50 values of >30 uM.AB-452 reduced HBsAg, HBeAg, and HBV DNA production with EC50 of 0.28-6.8 nM, without cytotoxicity.AB-452 interferes with multiple steps of HBV life cycle by reducing HBV RNA.AB-452 demonstrated antiviral activity in AAV-HBV-transduced mouse model.AB-452 promotes HBV RNA degradation through inhibiting PAPD5 and PAPD7 enzymatic activities and blockage of guanosine incorporation into viral RNA poly(A) tails..
