Abstract
Several drugs which react with DNA decrease hepatitis B viral (HBV) DNA polymerase activity in vitro. Because such an alteration of viral replication, if produced in patients with hepatitis B surface antigen (HBsAg)-positive chronic hepatitis, may lead to elimination of viral infection, we conducted a controlled trial of the use of the intercalating agent, quinacrine hydrochloride, in treatment of HBsAg-positive chronic hepatitis. No patient converted from HBsAg positive to negative during the trial and no consistent effect on HBV DNA polymerase activity was noted. Following treatment, elevated transaminase values and alterations of HBV markers were observed in several patients. Fluctuations of transaminase values and HBV markers may reflect alterations in host immunity and viral replication. Quinacrine alone is ineffective in therapy of chronic HBV infection. Additional study with intercalating agents, perhaps in conjunction with other drugs, is suggested.

Abstract:
Intercalating agents, some of them in clinical use, were tested for their ability to inhibit the hepatitis B virus specific DNA polymerase reaction. Ethidium bromide was shown to be the strongest inhibitor among the compounds tested. Compounds in clinical use inhibited the DNA polymerase test only at high concentrations. The inhibitory activity of all compounds tested was increased when the MgCl2 content in the reaction mixture was lowered. UV absorption studies presented no evidence that this effect was due to complex formation of magnesium and the individual compounds. The therapeutic significance of these findings is not certain and needs further work.作者: 一六阳 时间: 2010-11-8 02:31
