Gallic acid is a substance with anti-cancer activity including lung cancer. The potency of gallic acid as a cytotoxic agent can be improved by modifying its side chains. This study was aimed to examine the cytotoxic activity of gallic acid and its derivates in lung cancer cells, A549. In this study, cells were treated with gallic acid and its derivates and were incubated for 48 hour. After incubation period, percentage of cell viability over control were tested using MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulophenyl)-2Htetrazolium) assay. Afterwards, data were analysed using GraphPad Prism to obtain inhibitory concentration (IC50).

The result showed gallic acid, methyl gallate, ethyl gallate, propyl gallate, butyl gallate, isobutyl gallate, t-butyl gallate, and amyl gallate did not have cytotoxic activity. Isoamyl gallate showed cytotoxic activity, but the IC50 value was probably >51,2 μg/ml. That gallic acid derivatives with cytotoxic activities and IC50 <51,2 μg/ml were heptyl gallate and octyl gallate with IC50 values of 19,11 μg/ml and 41,23 μg/ml, respectively. However, methoxy gallate (monometohoxy gallate, dimethoxy gallate, and trimethoxy gallate) did not show any cytotoxic activity. We conclude that heptyl gallate and octyl gallate have better cytotoxic activity in A549 cells compared to gallic acid, while methoxy gallates do not have cytotoxic activity in cell A549.

Ginger is used for treating motion sickness, nausea and vomiting. The traditional Thai method of preparation is to steam the rhizome before preparing the remedy. There is no report comparing the biological activity and quality of extracts from steamed and non-steamed rhizomes. The objective was to compare the anti inflammatory activities, cytotoxicity and quality of steamed and non-steamed ginger extracts. All extracts were tested for their potential anti-inflammatory properties via the inhibitory effect on NO and PGE2 production, and cytotoxic activity via sulforhodamine B assay. Loss on drying, total ash and acid - insoluble ash determinations were used as quantitation evaluation to standardize the ginger extracts. The results showed that the quality of all samples was within standard guidelines. The anti-inflammatory NO inhibition effect was higher in the steamed ginger ethanol extract (AZOE) than in the non-steamed ginger ethanol extract (HZOE), but lower than prednisolone as a positive control, with IC50 values of 13.47 ± 0.20, 19.64 ± 0.33 and 1.33 ± 0.02 µg/ml, respectively. The effect of PGE2 inhibition of AZOE, HZOE and positive control, had IC50 values of 0.40 ± 0.06, 0.63 ± 0.02 and 0.066 ± 0.004 µg/ml, respectively. However, the steamed and non-steamed ginger ethanol extracts were not cytotoxic to either SKOV - 3 or HeLa cells. Steamed ginger had a higher inhibition effect on NO and PGE2 release than non - steamed ginger. These results support the traditional Thai method of steaming the rhizome before preparing the medicine.

Cervical cancer is the second most frequently occurring cancer among females all over the world. Since the best strategy against cancer is to kill the cancer cells without endangering the normal cells, discovering a potentially selective anticancer agent from plants has become very challenging for researchers worldwide. A previous study on Anredera cordifolia, known as binahong in Indonesia, revealed its cytotoxic activity on HeLa cervical cancer cells with IC50 75 µg/mL. However, the selectivity of the chemical agent and its molecular target was not investigated. Thus, this study was aimed at determining the selectivity of ethanolic extract of Anredera cordifolia leaf (EAC) on Vero cells and its molecular target on HeLa cells. The extracts were prepared by macerating A. cordifolia leaf powder in 70% ethanol. The viability of Vero cells was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. While the cell cycle of HeLa cells was analyzed using the flow cytometry, the molecular target of the extract was investigated by using the immunocytochemical staining. The results exhibited the selective cytotoxicity of EAC on HeLa cells compared to Vero cells with a Selectivity Index (SI) of 17.36. It arrested the G1/S phase of the cell cycle and suppressed the Bcl–2 expression, the anti-apoptotic protein, which also regulates the cell cycle. These findings confirmed the use of A. cordifolia leaf extract as a promising anticancer agent against cervical cancer, particularly the HeLa cells.

The high incidence of dengue virus infection and also the absence of effective vaccine cause researchers to look up to use the natural extract as the alternative remedy against the dengue virus (DENV). Curcumin is one of the natural extracts that has already proven to have antiviral effect. The objective of this study experiment aimed to see whether curcumin can be used as the antiviral against dengue virus. Several experiments were conducted to obtain the percentage of inhibition of DENV replication and also to determine the cytotoxic effect of curcumin to mammalian cells. This study was an experimental study that had been conducted at Microbiology Departement of Faculty Medicine of Universitas Indonesia. In this experiment, there were six treatment groups such as four different concentrations of curcumin, negative control and Dimethyl sulfoxide (DMSO). The data from this study were analyzed using T-test method. From this study, the curcumin had been proven to successfully inhibit the replication of dengue virus. The treatment with higher dose of curcumin could totally inhibit the replication of DENV. When we gave less dose of curcumin, the percentage inhibition dropped significantly. This showed that inhibition by curcumin was in dose-dependent manner. Furthermore, from these data we determined the IC50 of curcumin which was less than 0.1 µg/ml. The CC50 of curcumin was 3,46µg/ml. By comparing the result of CC50 and IC50, we found the selectivity index value was more than 34. From this study, it can be concluded that Curcumin can be used as antiviral against dengue virus in the future.

Latar belakang: Kanker kolorektal merupakan salah satu kanker dengan prevalensi tertinggi di dunia. Pengobatan kanker yang berdasarkan pembedahan dan kemoterapi masih memberikan prognosis yang kurang baik bagi kebanyakan pasien. Tatalaksana dan zat antikanker yang tersedia dan teruji klinis juga masih memberikan efikasi yang kurang baik ditandai dengan angka mortalitas yang masih tinggi. Berbagai studi telah menunjukkan bahwa bunga kecombrang mengandung berbagai metabolit aktif yang berpotensi menjadi zat antikanker. Penelitian ini bertujuan untuk melihat profil fitokimia, sifat antioksidan dan sifat sitotoksik ekstrak etil asetat bunga kecombrang terhadap sel kanker kolon HT-29.  Metode: Penelitian ini menggunakan desain eksperimental in vitro menggunakan galur sel kanker kolon HT-29. Sebanyak 45 sampel sel HT-29 yang dibagi menjadi kelompok perlakuan dan kelompok kontrol positif akan diletakkan kedalam well plate dan diberikan konsentrasi secara serial. Analisis kandungan metabolit ekstrak dilakukan menggunakan skrining uji fitokimia dan uji KLT. Pengukuran sifat antioksidan akan dilakukan menggunakan metode uji dengan reagen DPPH dan untuk sifat sitotoksisitas menggunakan metode MTT assay. Nilai absorbansi dan persen inhibisi dari kedua metode ini kemudian akan dibandingkan antara kelompok ekstrak dan kelompok kontrol positif menggunakan analisis regresi linear multipel.  Hasil: Berdasarkan uji fitokimia dan uji KLT, ekstrak etil asetat bunga kecombrang mengandung 4 golongan metabolit sekunder aktif seperti saponin, flavonoid, alkaloid dan triterpenoid. Ekstrak etil asetat bunga kecombrang tidak menunjukkan adanya sifat antioksidan ditandai dengan nilai IC50 pada uji DPPH sebesar1282 ppm dan menunjukkan sifat sitotoksitas moderat ditandai dengan nilai IC50 pada uji MTT assay sebesar 71 ppm. Hasil uji regresi linear multipel juga menunjukkan bahwa sifat antioksidan vitamin C dan sifat sitotoksisitas doksorubisin sebagai kontrol positif masih lebih unggul dibandingkan dengan ekstrak etil asetat bunga kecombrang.   Kesimpulan: Ekstrak etil asetat bunga kecombrang tidak memiliki sifat antioksidan dan memiliki sifat sitotoksik moderat. Kekuatan antioksidan dan sitotoksisitas ekstrak juga tidak sepadan bila dibandingkan dengan agen antioksidan dan sitotoksik konvensional seperti vitamin C dan doksorubisin. Oleh karena itu, diperlukan studi lanjutan dengan tingkat yang lebih tinggi dan jumlah sampel yang lebih besar lagi.  ......Introduction: Colorectal cancer is one of the most prevalent cancers in the world. Current anticancer treatments, which are based on surgery and chemotherapy still provide poor prognosis for most of the colorectal patients. Many studies have been conducted to learn about the extract from torch ginger flower as a potential candidate for anticancer agent. The goal of this study is to gather knowledge about the phytochemistry profile, antioxidant activity, and cytotoxic activity from ethyl acetate extract against HT-29 colon cancer cells. Method: This was an in-vitro experimental study using HT-29 colorectal cancer cell line. 45 samples of HT-29 cells were divided into 2 groups which were the positive control group and the extract group. We used phytochemical screening test and thin plate chromatography to analyse the metabolite content from the extract sample. The antioxidant, the extract’s cytotoxic activity, and the positive control group were analysed using the DPPH method and the MTT assay respectively. We then compared the absorbance value and the inhibition percentage from the extract group to the positive control group using multiple linear regression.  Result: Based on phytochemical screening and thin plate chromatography, ethyl acetate extract from torch ginger flower contained 4 groups of active metabolites such as  saponin, flavonoid, triterpenoid, and alkaloid. The extract group did not have antioxidant activity with IC50 1282 ppm and showed moderate cytotoxic activity with IC50 71 ppm. From multiple linear regressions, there was a significance difference between the extract and the positive control group for both antioxidant and cytotoxic activity. This study showed that the positive control group which was vitamin C for antioxidant and doxorubicin for cytotoxic, had better activity than the extract group. 

Conclusion: Ethyl acetate extract did not have any antioxidant activity and had moderate cytotoxic activity. However, the cytotoxic activity was also disproportionate when compared to the conventional positive control group. Therefore, further studies with a higher rate and a larger number of samples are needed.
