| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

| Shipping Condition | Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request. | ||
| Description | Helioxanthin derivative 5-4-2 is an analogue of helioxanthin, exhibites significant in vitro anti-HBV activity with EC50 of 0.08 uM in HepG2.2.15 cells.
IC50 value: 0.08 uM (EC50) [1][2]
Target: Anti-HBV
Helioxanthin derivative 5-4-2 had potent anti-HBV activities in HepG2.2.15 cells, with the EC50s of 1 and 0.08 microM, respectively. The lamivudine-resistant HBV, L526M/M550V double mutant strain, was also sensitive to helioxanthin and 5-4-2. This class of compounds not only inhibited HBV DNA, but also decreased HBV mRNA and HBV protein expression. The EC50 of HBV DNA inhibition was consistent with the EC50 of HBV 3.5 Kb transcript inhibition, which was 1 and 0.09 microM for helioxanthin and 5-4-2 respectively. References: | |||||

Helioxanthin derivative 5-4-2, an analogue of helioxanthin (ACH126447), is a small-molecule inhibitor of HBV, HSV-1and HSV-2 virus with EC50 values of 0.08 μM, 0.29 μM and 0.16 μM, respectively [1].
Helioxanthin derivative 5-4-2 is a lactam and has been reported to inhibit the HBV DNA and RNA and viral protein expression [2]. Helioxanthin derivative 5-4-2 has significant anti-virus activity with EC50 values of 0.08 μM, 0.29 μM and 0.16 μM for HBV(hepatitis B virus), HSV-1(herpes simplex virus type 1) and HSV-2(herpes simplex virus type 2), respectively [1]. In addition, Helioxanthin derivative 5-4-2 inhibited HBV replication by post-transcriptional down-regulation of necessary transcription factors [3]. Helioxanthin derivative 5-4-2 has also exhibited potent anti-HCV (hepatitis C virus) activity with 55% inhibition at 1.0 μM and 80%inhibition at 3.0 μM [1].
