    Board of directors of Guizhou bailing Group Pharmaceutical Co., Ltd

    December 20, 2013 Recently, we have made some preliminary understanding of the specific anti HBV mechanism of Guizhou bailing's new anti HBV drug, horseshoe gold derivative Y101 (tefentai)

    Mechanism of anti HBV: 1

    Directly interfere with the synthesis of HBV DNA; 2

    Synthesize antigens on the surface of HBV so that the human immune mechanism can recognize and eliminate them; 3

    Summary of other mechanisms (involving confidentiality temporarily not disclosed): Y101 (tefentai) anti HBV is multi-target, and some drugs commonly used at present are single target

    This is the first advantage of Y101 as a new anti HBV drug: multi target anti HBV

    Thanks to the multi-target mechanism, Y101 (tefentai) has gained a major feature in the anti hepatitis B virus test at present, that is, the virus inhibition effect is very good, the symptom rebound phenomenon is weak after drug withdrawal, and it does not need long-term continuous medication, which is the second advantage that can be expected

    Interferon and nucleoside need to be used for a long time, especially the latter

    The third advantage is that the bioavailability is up to 64%, which can be used orally, which is relative to interferon and therapeutic vaccine

    The fourth advantage is that the completed pharmacological and toxicological tests show less adverse reactions and less damage to normal cells

    This is not surprising, because the common people of horseshoe gold, the original medicine of Y101, have been using it for a long time

    They haven't heard of any special side effects

    In Taiwan, some people even use it to grind powder to cure colds

    The fifth advantage is that as mentioned above, Y101 (tefentai) has a strong liver protection effect in addition to anti-virus

    Experiments show that Y101 has a significant protective effect on the damaged liver tissue

    After using Y101, the symptoms of elevated liver transaminase are significantly relieved

    One of the most popular new anti HBV drugs in foreign countries is rep 9, which is produced by replicor company

    Rep 9 also has some similar characteristics

    First, it is also multi-target

    Rep 9 can inhibit two important viral proteins in the process of hepatitis B virus replication: neuraminidase and erythroagglutinin

    The antiviral effect of rep 9 is also relatively broad-spectrum, and it is effective for 12 kinds of viruses, including influenza, hepatitis B and C, HIV, RSV and herpes

    However, Y101 and its original drug, horseshoe gold, have shown some broad-spectrum characteristics in the past practice

    Finally, it should be noted that the above words do not mean that Y101 has been a successful new generation of anti hepatitis B drugs, and the development process of new drugs is still relatively long, which must be completed

    However, it is gratifying that at present, Guizhou bailing has made important progress in the research and development of Y101, a new class of anti hepatitis B drugs, and has completed its clinical application At the same time, all the pre bed studies have also applied to the national drug regulatory department for clinical trials

    Although the process is long, it does not exclude that the national policy is expected to make the product enter the market ahead of time

    At present, from the information obtained by Y101 (tefentai) and some characteristics that have been understood, there are some common features, or potential, of the next generation of new anti HBV drugs.
