Abstract

Pasak bumi is one of the Indonesian original plants having anti cancer activity. One compound of akar pasak bumi, i.e eurycomanone was proven to have cytotoxic effect on cancer cell culture by apoptosis induction on HeLa cells. Therefore, this study was aimed to isolate and identify euycomanone from akar pasak bumi and to look at the anti angiogenic activity of the compounds on corio alantois membrane (CAM) of chicken embryo induced by bFGF.The akar pasak bumi was ground and was macerated with methanol. The macerate was fractioned by mean of VLC. Six fractions was obtained. The second fraction exhibited two spots on a TLC system, one spot was cochromatographed with eurycomanone as the reference standart and another spot exhibited blue fluorecence at 254 nm. This second fraction, then, was chromatographed on a preparative scale TLC to separate isolate A. Anti angiogenic test was performed for Isolate A at concentration series of 5, 10, 15, 20, 40 μg/mL respectively. Egg embrio (8-9 days) were divided into 8 groups. The first group was implanted paper disc only, the second group were given bFGF on Tris HCl buffer and the third group were given bFGF (on Tris HCl buffer) + 0,8 % DMSO. The fourth to eighth group were induced by 10 ng bFGF and the test preparation at the respective concentration. After incubation at 39 °C for 3 days, each egg was opened, the content of each was aspired and discarded, the CAM sticked to its shell was examined macroscopically and microscopically for the formation of new blood vessels.Based on spectral data of UV, IR, 1H NMR, 13C NMR and MS of isolate A and comparison with the spectral data of the standart, the isolate A was eurycomanone. Eurycomanone inhibited angiogenesis at concentration of 10 μg/mL.Key words: antiangiogenic, angiogenesis, E.longifolia, eurycomanone,CAM.

Abstract

The cytochrome P-450 (CYP) and glutathione S-transferase (GST) enzyme systems may influence the biological effects of carcinogens. As such, these enzymes may predict the developmental risk of breast cancer, as well as be potential targets for chemoprevention. The purpose of this study was to compare the expression of CYP1A1 and GST* between treatment groups. Expression of CYP1A1 and GST* was quantified in liver tissue from 18 female Sprague Dawley rats aged 40 days, which randomly divided into six treatment groups. Those are base line group (without DMBA and ethanolic extract treatment), DMBA induced cancer group, the other two groups was administrated by DMBA after treated by ethanolic extract in two different doses, 300 mg /kg BW and 750 mg/kg BW. The last two groups were given two doses of extract ethanolic only, without initiated of DMBA. The ingestion of the extract was carried for three weeks and the ingestion of DMBA was performed twice in the third week. The expression CYP1A1 and GST was quantified by immunohistochemistry. CYP1A1 expression was significantly higher (P < 0.05) in cancer group (DMBA) as compared with other groups. On the other hand, GST expression was lower in cancer group (P < 0.05). Result of this study demonstrated that ethanolic extract leaves of G. procumbens in 300 mg/kg BW dose could inhibit CYP1A1 stronger than are other and induced GST* level. Has effect on ethanolic extract leaves of G. procumbens has ability in played role of as blocking agent in preventing initiation stage of carsinogenesis, therefore it should be taken into account for chemopreventing agent in mammary carsinogenesis.Key words : Gynura procumbens, breast cancer, Chemopreventive, CYP1A1, GSTμ

Abstract

The study was conducted to observe the effect of extracts of ngokilo (Gynura procumbens), beluntas (Pluchea indica), murbei (Morus alba) dan tapak doro (Vinca alba) leaves. Showed anticarcinogenic activity on lung tumor growth of mice. In the nex step, compounds having anticarcinogenic effect was isolated and identified, and evaluated on the cultures of meilomaand Vero cells. The results showed that non-polar fraction of ethanol extract of ngokilo leaves did not have anticarcinogenic activity, whereas the polar fraction show anticarcinogenic activity. At least there were three flavonoids (flavon or flavonol groups) in this polar fraction. It was only two of these flavonoids inhibit the growth of myeloma and Vero cells.Key words : ngokilo, Gynura procumbens, anticarcinogenic, flavonoid.
