In vitro anti-HIV activity of crude extracts from Tinospora cordifolia
BMC Infectious Diseases volume 12, Article number: P10 (2012)
Human immunodeficiency virus (HIV) infection causes acquired immune deficiency syndrome (AIDS) and is a global public health issue. Anti-HIV therapy involving chemical drugs has improved the life quality of HIV/AIDS patients. However, emergence of HIV drug resistance, side effects and the necessity for long-term anti-HIV treatment are the main reasons for failure of anti-HIV therapy. Therefore, it is essential to isolate novel anti-HIV therapeutics from natural resources. The aim of the present study was to evaluate the invitro anti-HIV activity of T. cordifolia plant extracts.
Extracts were prepared from dried leaves in n-hexane, dichloromethane, ethyl acetate and n-butanol. A toxicity study was performed on all crude extracts using peripheral mononuclear blood cells (PBMCs) isolated from whole blood. HIV-1 RT inhibition activity of the all solvent extracts of T. cardifolia was determined using a commercial kit.
Among the tested extracts, the n-hexane and n-butanol crude extracts of T. cordifolia showed moderate cytotoxic activities against PBMCs with CC50 values ranging from 5.7-12.0 µg/ml. In the HIV-1 reverse transcriptase assay T. cardifolia plant extracts showed good inhibitory activity, which was near that of the reference drug. Ethyl acetate extract shows 85 percentage of HIV-1 RT inhibition activity at a concentration of 20 mg/ml.
The leaves of T. cardifolia extracts are shows anti-HIV 1 activity and this plant has great potential for developing useful drugs. Extraction of important biologically-active phytochemicals from this plant will certainly be helpful in protecting and treating various viral diseases in human beings.
