Abstract

Penelitian sebelumnya menunjukkan bahwa analog kurkumin PGV-1 dapat menghambat pertumbuhan sel kanker payudara pada fase G2-M dan menginduksi terjadinya apoptosis. Penelitian ini dilakukan untuk membandingkan pengaruh molekuler analog kurkumin PGV-0 dan kurkumin dengan PGV-l pada siklus sel dan apoptosis. Metode flowcytometry dilakukan dengan menganalisis pengaruh perlakuan PGV-1 (2,5 µM), PGV-0 (5,0 µM) dan kurkumin (10,0 µM) terhadap distribusi sel pada berbagai fase siklus sel T47D. Metode Western blot dilakukan untuk mengamati pengamh perlakuan senyawa uji terhadap protein yang terlibat pada siklus sel (p21 dan Cdc-2) dan apoptosis (Caspase-3/7/9). Hasil pengamatan pada perlakuan dengan PGV-1, PGV-0 dan kurkumin menunjukkan fenomena hiperploidi. Perlakuan dengan PGV-l secara spesifik menunjukkan fenomena penghambatan pada fase G2-M. Pengamatan molekuler menunjukkan PGV-1 dan PGV-0 mampu mempengaruhi ekspresi protein p21 dan Cdc-2 sedangkan kurkumin hanya mempengaruhi aktivasi Cdc-2. Ketiga senyawa uji terbukti mampu menginduksi apoptosis pada sel T47D melalui aktivasi Caspase-3/7. Secara keseluruhan, perlakuan ketiga senyawa uji mampu mempengaruhi siklus sel dan dapat menginduksi terjadinya apoptosis pada sel T47D

Abstract

The initial research of Jati Belanda leaves extract (JBE) showed the inhibition of breast cancer cell growth (T47D). The phytochemistry screening showed that JBE contain flavonoid, alkaloid, polifenol, and volatile oil. The development of anticancer drugs need the molecular mechanism investigation in order to produce cancer-targeted drugs. The objective of this research is to determine the molecular mechanism of JBE cytotoxicity effect towards cancer cell lines. This research began with cytotoxicity asssay in vitro of JBE towards some cancer cell lines by MTT method. JBE was given in some variety of concentration. The result of this study showed that JBE do not contain tirosid, and contain flavonoid in the concentration of 0,976%. The result of cytotoxicity assay towards MCF-7, HeLa, T47D and Vero showed IC50 value 36,50; 58,02; 53,36; 1806,22 dan 2451,65 µg/mL respectively. It is concluded that JBE have a strong potency to inhibit the growth of WiDr cancer cell line.Keywords : jati belanda, T47D cells, cytotoxicity

Abstract

Several studies show that some plants and fruits could protect human body from free radical danger exposure. Zingiberaceae family has some chemical substances that have antiradical activity, such as phenolic compound and flavonoid. The aim of this study is to determine the correlation of total phenolic compound towards its antiradical activity. Antiradical activity assay was determined by DPPH method (1,1 difenil-2-pikrilhidrazil). The total phenolic compound is determined by spectrofotometry using Folin-Ciocalteu reagent and counted as GAE (Gallic Acid Equivalent). Based on this study, the total phenolic concentration of ethanolic extract of jahe (Zingiber officinale (L.) Rosc), kencur (Kaemferia galanga L.), lengkuas (Languas galanga), lempuyang gajah (Zingiber littorale) and lempuyang pahit (Zingiber americana) is 73.99 mg/g; 23.848 mg/g; 37.841 mg/g; 49.725 mg/g and 40.802 mg/g respectively. The radical scavenging activity (IC50) of jahe (27.38 µg/mL), lengkuas (93,27 µg/mL), lempuyang pahit (105,08 µg/mL), meanwhile lempuyang gajah and kencur show low activity of radical scavenging.Keywords: Zingiberaceae, total phenolic compound, antiradical, DPPH
Acetoxy Chavicol Acetate (ACA) Concentration and Cytotoxic Activity of Alpinia galanga Extract on HeLa, MCF7 and T47D Cancer Cell Lines Suhendi, Andi; Wikantyasning, Erindyah Retno; Setyadi, Gunawan; Wahyuni, Arifah Sri; Da'i, Muhammad

Abstract

Due to severe side effect and non-specific chemotherapeutic agent, screening and discovery for cancer therapy are still working, especially from natural resources. Traditionally, people used herbal medicine either to prevent or cure diseases. One of herbal that commonly used in Indonesia is Alpinia galangal. Previous study stated that active compound is acetoxy chavicol acetate (ACA) and active as anticancer. This research aimed to determine ACA concentration and cytotoxic activity of Alpinia galanga extract (AGE) from three local markets on HeLa, MCF7 and T47D cell lines. The galangal used from three local markets namely Pasar Legi Surakarta, Beringharjo Yogyakarta, and Wonogiri. The extraction was performed by maceration using 96% ethanol as solvent. ACA quantitation using UV spectrophotometer at λ = 208.5 nm. Samples were prepared by liquid-liquid extraction using an ethyl acetate. Cytotoxic activities were performed by MTT assay. The result showed that the concentration of ACA of AGE from the three local markets were 3.798; 0.035; and 0.009 % w/w, respectively. Cytotoxic activity, describes as IC50 value, on HeLa cell line of AGE from three local markets, in order were 13.26; 36.32 and > 100 µg/ mL. Meanwhile, AGE from Pasar Legi on MCF7 and T47D cell lines have IC50 value of 15.80; 12.50 µg/ mL, respectively. In contrast, two other samples have IC50 values of greater than 100 µg/ mL. The highest activity was from the highest concentration of ACA on the samples.Key words: Alpinia galanga, HeLa, T47D, MCF7 and Acetoxy chavicol acetate
