Chemical Structure
VK-2019
- CAS No.: 2044520-06-9
- Formula:C29H25NO4
- Molecular Weight:451.51
InChIKey: VUJZFNSWCNSGDV-UHFFFAOYSA-N
SMILES: O=C(C1=C(C2=CC3=C(C=CN3)C=C2)C(C#CC4=CC=C(COC5CCOCC5)C=C4)=CC=C1)O
Biological Activity: VK-2019 is an orally bioavailable selective inhibitor of EBNA1. By binding to the protein-DNA interface to interfere with the recruitment and anchoring of the viral DNA replication machinery, VK-2019 effectively blocks the replication and proliferation of EBV in latently infected cells. VK-2019 reduces the copy number and gene expression level of Epstein-Barr virus in tumor cells, decreases the number of EBER-positive cells, and exhibits significant antiviral, immunomodulatory and antiproliferative activities. VK-2019 successfully inhibits tumor growth in EBV-dependent xenograft models. VK-2019 has favorable systemic exposure and acceptable safety profiles, and is widely used in research on advanced nasopharyngeal carcinoma and various EBV-associated cancers[1][2][3].
