Abstract

Ethanol extract of Syzygium cumini (jamblang) leaves reveal its significant α-glucosidase inhibitory activity which perform the potential activity of this plant extract as antidiabetic agent. However, other bioactivities of this plant extract have been reported. The aim of current study was to evaluate the comparison of in vitro antidiabetic, antioxidant and cytotoxic activity of S. cumini fractions. The S. cumini leaves ethanol extract was fractionated by using column chromatography with n-hexane, ethyl acetate and methanol as eluents. Seven fractions were obtained from column chromatography (F1-7). The results showed that the best antidiabetic activity was found in F5 (93% α-glucosidase inhibitory activity), the best antioxidant activity was found in F4 (83% inhibition of DPPH free radical) and the best cytotoxic activity was found in F2 (69% growth inhibition of T47D breast cancer cell line). Therefore besides in vitro antidiabetic activity, fractions of S. cumini leaves ethanol extract also showed antioxidant and cytotoxic activities. Since the results showed that the most active fractions for antidiabetic, antioxidant and cytotoxicity were differed, it could be possible to isolate the different potential active compounds for each activity.Keywords : Syzygium cumini, α-glucosidase inhibitor, DPPH, cytotoxicity

Abstract

Research into plants with anticancer effects is actively encouraged in orderto discover new drugs with lessertoxicity but more potent effects. The aims of study are to evaluate the antioxidant properties and to investigate the cytotoxic activity of Plectranthus amboinicus (Lour.) Spreng. leaves ethyl acetate fractions on HeLa,T47D and MCF7 cell lines. The extract was prepared by graded maceration using n-hexane and ethyl acetate. The ethyl acetate extract was fractionated in vacuum liquid chromatography with n-hexane: ethyl acetate; and ethyl acetate: methanol as mobile phase. Then, the fractions were analyzed with thin layer chromatography (TLC). The free radical scavenging activity was measured by DPPH method, the total flavonoid content was calculated by quercetin equivalent and the absorbance is measured by using UV-Visible spectrophotometry. The cytotoxic activity were determined using MTT assay. The fractions contained 5 sub fractions with same TLC profile. The fractions showed antioxidant activity by DPPH method with different IC50 values, namely: 130 µg/mL(I), 127 µg/mL(II), 137 µg/mL(III), 129 µg/mL(IV), and 124 µg/ mL(V), respectively. The measurement of total flavonoid content showed 118 mg QE/g (I), 50 mg QE/g (II), 207 mg QE/g (III), 56 mg QE/g (IV), and 55 mg QE/g (V). The IC50 of each sub fractions on HeLa cell were 77 µg/mL, 46 µg/mL, 93 µg/mL, 71 µg/mL and 476 µg/mL; for T47D cell were 1621 µg/mL, 111 µg/mL, 128 µg/mL, 150 µg/mL and 209 µg/mL; and for MCF7 were 259 µg/mL, 343 µg/mL, 575 µg/mL, 408 µg/mL and 250 µg/mL. Based on the results, the fractions derived from ethyl acetate extract of Plectranthus amboinicus (Lour.) Spreng. leaves exhibit antioxidant. The Fraction II from ethyl acetate extract of Plectranthus amboinicus (Lour.) Spreng. was the most cytotoxic on HeLa, T47D and MCF7 cell lines. It is potential to undergo further isolation of its cytotoxic compounds.Keywords : antioxidant, cytotoxic, Plectranthus amboinicul (Lour.) Spreng., ethyl acetate fractions

Abstract

Human erythropoietin (hEPO) is a glycoprotein that regulates the formation of erythrocytes and mainly used in anemia patients. Previously, we have reported the expression of modified human EPO with 2 additional N-linked in mammalian cell CHO-K1. The aim of this current research was to study the optimum condition for modified recombinant hEPO (rhEPO) production in CHO-K1. To do this, several parameters of culture conditions were applied including antibiotic concentrations, seeding densities, time of incubations, fetal bovine serum (FBS) concentrations and cell culture media. The result showed that the presence of antibiotic G418 improved the expression level with the highest was at 1% of concentration. Meanwhile, seeding density of 2–3x105 cells/6 cm dish and seven day of incubation time were the best condition for rhEPO protein expression. From five different combination media used, F12 medium with 10% FBS gave the highest expression of rhEPO protein. From this study was also found that at passage 16 the expression level was still increasing proving that the clone expressing the protein of our interest is promisingly stable.Keywords : EPO, erythropoietin, protein expression, CHO-K1, optimation

Abstract

It has been known that there are differences in response to medications both in terms of clinical activity and side effects. Among all influencing factors, genetic variation has been considered to play a crucial part. By genetic investigation, the differences in drug metabolism, transport and target could be disclosed. Termed as “pharmacogenetics (PGx)”, that focuses on the variants within one or more candidate genes. Genetic tests have been started for screening polymorphisms prior to drug prescription, moreover many biomarkers were developed in oncology. Recent PGx investigations have been conducted to identify mRNAs, microRNAs (miRNAs) and other downstream signals that are affected by variation in genes that might cause drug response variability. Another intriguing study related to PGx in cancer stem cells (CSCs) has recently aroused. CSC shows more resistant behavior to drug. CSCs are subpopulation of cells, which share some same markers with stem cells. CSC can induce specific signal transduction pathways. Variation in genes affect CSCs activity are generally neglected in the past PGx studies. This could be one of the explanation why past PGx studies in cancer cell do not achieve optimal clinical outcome. Keywords : pharmacogenetics, pharmacogenomics, microRNAs, cancer stem cells

Abstract

Highly and uncontrolled cell proliferation on cancer cells may boost ROS level intracellular accumulation up significantly. Sappan heartwood (Caesalpinia sappan L.) have been known to have cytotoxicity effect toward several cancer cells. This research was conducted to develop Caesalpinia sappan L. heartwood ethanolic extract (CSE) as chemopreventive agent which can be used as cancer therapy, looked from antioxidant and anti-senescence activity toward 4T1 breast cancer cell. CSE was obtained through maceration using ethanol 70% as solvent. Cytotoxicity activity of CSE was done by using MTT assay with IC50 as parameter. This IC50 was used as basic to the next assay, ROS assay by using DCFDA staining flowcytometry to look ROS level intracellular of CSE toward 4T1 cell and senescence assay by using senescence associated β-galactosidase (SA β-gal) assay with % cell senescence as their parameter. CSE toxic to 4T1 cell that proved from IC50 value of 25 µg/mL. Single treatment of CSE on concentration 12,5; 25; and 37.5 µg/mL able to suppress ROS level intracellular. If compared with untreated cell, single treatment of CSE on concentration 6 and 12 µg/mL showed % cell senescence not significantly different. Based on this result, CSE is cytotoxic, has antioxidant and antisenescence activity, so it has great potential to developed as chemoprevention agent on cancer therapy.Keywords : Caesalpinia sappan L., 4T1 breast cancer line, Reactive Oxygen Species (ROS), anti-senescence
