Helioxanthin 8-1
Based on 2 publication(s) in Google Scholar
Helioxanthin 8-1(Helioxanthin analogue 8-1) is an anti-HBV agent. Helioxanthin 8-1 exhibits anti-hepatitis B virus activity in both in vitro human hepatitis B virus models and animal models. Helioxanthin 8-1 inhibits the synthesis of duck hepatitis B virus (DHBV) DNA, covalently closed circular DNA, RNA and proteins, thereby blocking DHBV replication. Helioxanthin 8-1 shows higher cytotoxicity in virus-induced cells than in non-induced cells. Helioxanthin 8-1 can be used in studies related to hepatitis B virus infection.

Helioxanthin 8-1 (0.1-3 μM; 6 days) potently inhibits DHBV replication in induced dstet5 cells, with an IC50 value of 0.25 μM against viral DNA, 0.1 μM against viral RNA, and 0.1 μM against core protein. It also reduces cccDNA levels in a dose-dependent manner[1].
Helioxanthin 8-1 (0.03-0.3 μM; 6 days, in combination with 3TC) exhibits additive anti-DHBV activity in dstet5 cells when used in combination with 3TC (HY-B0250). Enhanced viral DNA inhibition is observed across the combined concentration range, with a CI value of 0.82[1].
Helioxanthin 8-1 (10-50 μM; 3 days) exhibits higher cytotoxicity towards virus-induced dstet5 cells (CC50 = 18 μM) than towards uninduced dstet5 cells (CC50 = 45 μM)[1].
Helioxanthin 8-1 (100 μM; 48 h) reduces the viability of Vero cells (ATCC CCL-81) to 70.6%, with a CC50 value of >100 μM[2].
