Abstract

Sodium taurocholate cotransporting polypeptide (NTCP) is a multiple transmembrane transporter predominantly expressed in the liver, functioning as a functional receptor for HBV. Through our continuous efforts to identify NTCP as a novel HBV target, we designed and synthesized a series of new compounds based on the structure of our previous compound NT-5. Molecular docking and MD simulation validated that a new compound named NTI-007 can tightly bind to NTCP, whose efficacy was also measured in vitro virological examination and cytotoxicity studies. Furthermore, Autophagy was observed in NTI-007 incubated HepG2.2.15 cells, and results of q-PCR and Western blotting revealed that NTI-007 induced Autophagy through NTCP-APOA1-HBx-Beclin1-mediated pathway. Taken together, considering crucial role of NTCP in HBV Infection, NTCP-mediated autophagic pathway may provide a promising strategy of HBV therapy and given efficacy of NTI-007 triggering Autophagy. Our study suggests pre-clinical potential of this compound as a novel anti-HBV drug candidate.
