Embodiment 1

[0068] Example 1 - Evaluation of the in vitro anti-HBV activity of the test compound fenretinide using HepG2-NTCP cells

[0069] The compound preparation method is as follows:

[0070] Taking the preparation of 10mM concentration as an example, the volume of solvent DMSO (μl) = sample mass (mg) × purity ÷ molecular weight ÷ 10 × 10 6

[0071] Control compounds included ETV (lot number: P1214012; 99.0% purity), purchased from Shanghai Titan Technology Co., Ltd.; and RG7834 (RG7834, also known as RO 7020322, a highly selective and orally bioavailable HBV inhibitor with potent Inhibits HBV antigens (HBsAg and HBeAg) and HBV DNA. Lot number: ET25747-14-P1; 99.5% purity), obtained from Shanghai WuXi AppTec New Drug Development Co., Ltd. The stock concentrations of the above control compounds were all 20 mM and stored at -20°C.

Abstract

The invention provides an application of fenviretin A in preparation of a medicine for treating or preventing viral hepatitis. Specifically, the invention provides application of a compound 1, a derivative of the compound 1 or pharmaceutically acceptable salt of the compound 1 in preparation of drugs for treating or preventing viral hepatitis, and preferably, the viral hepatitis is hepatitis B. The invention also provides a pharmaceutical composition for treating or preventing viral hepatitis, which comprises compound 1 or a pharmaceutically acceptable salt thereof and optionally one or more additional therapeutic or prophylactic agents, as well as a pharmaceutically acceptable carrier.

Description

technical field [0001] The present invention relates to the technical field of antiviral drugs, in particular, to a pharmaceutical composition for treating or preventing viral hepatitis and its application. Background technique [0002] Human hepatitis B virus (HBV) infection is a major public health problem worldwide. After acute hepatitis B virus infection, about 8% still develop chronic hepatitis B infection, and persistent HBV infection will lead to liver cirrhosis and even liver cancer. my country is a big country with hepatitis B, with nearly 130 million hepatitis B virus carriers, accounting for about 9% of the total population. Although with the widespread popularization of hepatitis B vaccine, the infection rate of new hepatitis B has been effectively controlled, but the population base of hepatitis B carriers is large, and prevention and treatment of hepatitis B has become the top priority of my country's public health problems. HBV transmission is mainly through...
