Abstract

HIV-AIDS is a global problem and the deadliest disease in the world. One of HIV and AIDS prevention strategy can be done with traditional medicine research program from natural resource that has anti-HIV AIDS activity. It has been found that 70% ethanol extract of Justicia gendarussa Burm.f leaves, alkaloid free and alkaloid non-free, has a strong inhibitory activity against HIV reverse transcriptase enzyme, as an effort to find a solution in the face of HIV AIDS prevalence that is still high with problem of HIV-AIDS treatment such as side effects and resistances. Justicia gendarussa had already known for having an effect anti-HIV and therefore we were looking at the mechanism of inhibition of HIV Reverse Transcriptase enzyme. Both types of extracts were tested in vitro using ELISA technique and analysed chemical content of Gendarusin A as anti-HIV using high performance liquid chromatography. ELISA test results obtained percent inhibition, respectively for 254.2, 254.2, 235.6, and 279.7 for the concentration of 5 ppm, 10 ppm, 15 ppm and 20 ppm of free alkaloid extract and 169.0, 164.0, 130.5 and 369.5 for the concentration of 5 ppm, 10 ppm, 15 ppm and 20 ppm of non-free-alkaloid extract. The results of high performance liquid chromatography obtained Gendarusin A in the free-alkaloid extract at retention time 8.402 minutes and non-free alkaloid extract at retention time 8.381. Therefore, these results concluded that the Justicia gendarussa Burm.f can be a useful resource for the isolation and development of new anti-HIV.

Abstract

Justicia gendarussa Burm f. (Acanthaceae) is known for its activity as a male contraceptive and anti-HIV properties. The present study was designed to evaluate extracts of J. gendarussa for cytotoxicity activity against MOLT-4 cells. The cytotoxic activity of the fractionated-extract and 70% ethanol extracts of J. gendarussa leaves on MOLT-4 cells were evaluated using a WST-1 assay. The treatment cells, control cells without treatment and control media were also tested in duplicate. The absorbance was measured at a wavelength of 450 nm using a microplate absorbance reader (Bio-Rad). The average absorbance measures formazan produced by viable cells that metabolize the WST-1 reagent. Then the data was analyzed with regression analysis Microsoft Excel 2007 program to determine the concentration with 50% cell viability (50% Cytotoxicity Concentration, CC50). The CC50 values of the fractionated-extract and 70% ethanol extract of J. gendarussa leaves were 94 μg/ml and 78 μg/ml, respectively. The cytotoxicity of fractionated-extract and 70% ethanol extract of J. gendarussa leaves were not significantly different (p > 0.05). It can be concluded that the fractionated-extract and 70% ethanol extract of J. gendarussa leaves are not toxic to MOLT-4 cells.
