Abstract

Caesalpinia sappan is studied for several biological activities. The aim of this research is to determine the cytotoxic and antimigratory activities of Caesalpinia sappan active fraction in combination with cisplatin on human TNBC cells (MDA-MB-231). Caesalpinia sappan heartwood was extracted with methanol. Then, several fractions of the methanol extract were obtained by using a liquid-liquid extraction method followed by column chromatography. The cytotoxicity was determined using MTT assay. Synergistic effects were analyzed by calculating the combination index (CI). Migration was examined using wound-healing assay. Levels of MMP2 activity were determined with gelatin zymography assay. The results showed that most of the fractions included in this study exhibited cytotoxic effects against MDA-MB-231 cells, and C fraction demonstrated the highest cytotoxic activity of all fractions. The combination of C-cisplatin revealed a synergistic inhibitory effect on MDA-MB-231 cell growth (CI<1). Furthermore, C fraction, alone and in combination with cisplatin, inhibited migration of MDA-MB-231 and suppressed MMP2 activity. The C fraction isolated from Caesalpinia sappan increased the cytotoxic and antimigratory activities of cisplatin on MDA-MB-231 cells. Based on these findings, the potential of Caesalpinia sappan to act as a supportive agent in metastatic TNBC treatment with cisplatin warrants further exploration.

Abstract

Brazilein performs anti­cancer activities on several cancer cells and potentially inhibits metastasis. The aims of this study is to observe the synergistic cytotoxic and migration inhibitory effect of brazilein combined with cisplatin on 4T1 breast cancer cells. Under MTT assay, we found that brazilein revealed cytotoxic effect on 4T1 cells in a dose­dependent manner (IC50=50 ± 0.3 µM). Combination of brazilein and cisplatin showed synergistic effect (CI=0.72). Flowcytometry analysis on the cell cycle progression showed that single treatment of 25 µM brazilein induced G2/M­phase accumulation, 12.5 µM cisplatin induced S­phase accumulation, while combination of brazilein and cisplatin induced S­phase and G2/Mphase accumulation. Combination of brazilein and cisplatin induced apoptosis higher than that of the single treatments. Based on wound healing assay, 12.5 µM brazilein and its combination with 6.25 µM cisplatin inhibited cells migration. Immunoblotting and gelatin zymography analysis showed that combination of brazilein and cisplatin inhibited the expression level of Rac1 and MMP9 proteins. Based on these results, we conclude that brazilein enhanced cytotoxic activity of cisplatin and inhibited migration on 4T1 cells and potentially can be developed as an enhancing cytotoxic and antimetastasis agent.

Abstract

In the last decade, Indonesia intensifies the efforts to reduce pharmaceutical imports. One of the initiatives is establishing a paracetamol production facility to start operating in 2024. Kinetics study is needed as a basis to design the paracetamol reactor. This study investigated the optimal temperature, reactant mole ratio, and agitation speed in the reactor for paracetamol production. In this study, aqueous solution of para-aminophenol was reacted with acetic anhydride. The mole ratio of para-aminophenol to acetic anhydride was varied to 1:1, 1:1.2, 1:1.5, and 1:2 while the temperature was varied to 80 °C, 90 °C, and 110 °C. However, due to uncontrolled heat of the reaction and limitation of the mixture’s boiling point, the actual reaction temperatures were 86 °C, 90 °C, and 108 °C. In addition, the agitation speed of 250 RPM and 350 RPM were also studied. Thin layer chromatography (TLC) and densitometry were used to determine the concentration of paracetamol in the reacting mixture. The optimum temperature, reactant mole ratio, and agitation speed in this study were 108 °C, 1:1.5, and 350 RPM, respectively. In addition, a reaction performed under those operating parameters gave the reaction rate constant of 1.95 L mol-1 min-1.Keywords: acetic anhydride; kinetics; para-aminophenol; paracetamol; pharmaceutical industry A B S T R A KDalam sepuluh tahun terakhir ini, Indonesia bertekad mengurangi impor bahan baku farmasi. Salah satu upaya yang dilakukan adalah membangun fasilitas produksi parasetamol yang akan mulai beroperasi pada tahun 2024. Studi kinetika diperlukan sebagai dasar perancangan reaktor parasetamol. Oleh karena itu, penelitian ini mengkaji kondisi operasi optimal pada reaksi produksi parasetamol yang akan dibutuhkan sebagai dasar perancangan pabrik. Pada percobaan ini, para-aminofenol direaksikan dengan anhidrida asetat dengan media air. Rasio mol para-aminofenol terhadap asetat anhidrida divariasikan 1:1 1:1,2, 1:1,5, dan 1:2 sedangkan temperatur divariasikan 80 °C, 90 °C, dan 110 °C. Akan tetapi, karena panas reaksi yang tidak dikontrol dan batasan berupa titik didih dari campuran reaksi, temperatur aktual reaksi menjadi 86 °C, 90 °C, dan 108 °C. Selain itu, kecepatan putaran pengadukan juga divariasikan pada angka 250 RPM dan 350 RPM. Kromatografi lapis tipis (KLT) dan densitometri digunakan untuk menentukan konsentrasi parasetamol dalam campuran reaksi. Temperatur, rasio mol reaktan, dan kecepatan putaran pengadukan yang optimum pada penelitian ini masing-masing adalah 110 °C, 1:1,5, dan 350 RPM. Selain itu, reaksi yang dilakukan dengan kondisi operasi tersebut menghasilkan konstanta laju reaksi 1,95 L mol-1 menit-1.Kata kunci: anhidrida asetat, industri farmasi, kinetika, para-aminofenol, parasetamol

Abstract

RPTLC and optimizing mobile phase methods in Rm value determination as one of lipophylicity parameters in drug designBackground: The early process to successfully achieve its target is drug penetration or absorption. Of the three physicochemical parameters i.e, lipophyllicity, electronic and steric parameters, the lipophyllicity parameter is the most reponsible in drug absorption process. The research was aimed to determine retention modified (Rm) value of barbituric acid compound derivatives using RPTLC metod and mobile phase optimizing.Methods: This study was conducted on barbituric acid compound derivatives by using reverse phase thin layer chromatography (RPTLC). Silica Gel GF 254 that had been submerget in the mixture of liquid paraffin and petroleum eter (95:5) was used as a stationary phase. The mixture of polar to non polar solvent was used as mobile phase.Results: Research showed that in this method the most optimum of mobile phase was indicated by methanol and acetic acid mixture in the ratio of (1:9). The resulted Rm values of 5,5-diethylbarbituric acid, 5,5-diallylbarbituric acid, 5-allyl-5-isopropylbarbituric acid, 5-allyl-5-isobuthylbarbituric acid, 5-etil-5-(1-methylbutyl) barbituric acid, 5-(1-cyclohexene-1-yl)-1,5-dimethylbarbituric acid and 5-ethyl-5-phenylbarbituric acid were as follow 0.116; 0.144; 0.162; 0.221; 0.262; 0.187 and 0.199.Conclusions: The most optimum mobile phase in this method was the mixed solvents that had lower polarity, i.e, the mix of methanol and acetic acid in the ratio of (1:9). The H1 , H2 and H3 substituens in barbituric acid nuclei showed, the longer carbon chain, the higher the Rm values, howover the existing of double bond in such substituents will decrease the Rm value.Keywords: RPTLC, mobile phase, Rm value ABSTRAK Latar belakang: Proses awal keberhasilan obat dalam mencapai target adalah penetrasi atau absorpsi. Parameter lipofilisitas paling bertanggung jawab terhadap proses absorpsi obat dibanding parameter elektronik dan stearik. Tujuan penelitian ini adalah penggunaan metode RPTLC dan optimasi fase gerak dalam penentuan harga retention modified (Rm) senyawa turunan asam barbiturat.Metode: Penelitian dilakukan terhadap senyawa turunan asam barbiturat, dengan metoda kromatografi lapis tipis fase terbalik. Digunakan fase diam silika gel GF 254 yang telah dibacem dengan campuran parafin cair dan petroleum eter dengan perbandingan (95:5). Fase gerak yang digunakan dipilih campuran pelarut dari yang sangat polar sampai yang kurang polar.Hasil: Fase gerak yang paling optimum digunakan dalam metode ini adalah campuran metanol dan asam asetat dengan perbandingan (1:9). Harga Rm yang diperoleh secara berturutan, asam 5,5-dietilbarbiturat, asam 5,5-dialilbarbiturat, asam 5-alil-5- isopropilbarbiturat, asam 5-alil-5-isobutilbarbiturat, asam 5-etil-5-(1-metilbutil) barbiturat, asam 5-(1-sikloheksen-1-il) 1,5- dimetilbarbiturat dan asam 5-etil-5-fenilbarbiturat adalah: 0,116; 0,144; 0,162; 0,221; 0,262; 0,187 dan 0,199.Simpulan: Fase gerak yang paling optimum dalam metoda ini adalah bukan fase berair, tetapi berupa campuran pelarut yang mempunyai polaritas rendah, yakni campuran metanol dan asam asetat dengan perbandingan (1:9). Substituen atom H1 , H2 dan H3 pada inti asam barbiturat, menunjukkan makin panjang rantai karbon, makin tinggi harga Rm-nya. Adanya ikatan rangkap pada substituen menurunkan harga Rmnya.

Abstract

Ethanolic extract and brazilein-containing fraction of Caesalpinia sappan L., has been reported to inhibit cell proliferation in T47D (ER+ PR+/- cell, Luminal A subtype model). The Luminal A subtype is the most common subtype of breast cancer in Indonesian women. In this study, we explored the activity of the reduced form of brazilein, i.e. brazilin, in T47D cells proliferation and the mechanism that involved. The cytotoxicity activity of brazilin was observed using MTT assay. While the cell cycle modulation analysis was done by using flowcytometry, and the senescence assay was observed using S-A-β-galactosidase assay. The results showed that brazilin inhibited cell growth in a dose-dependent manner with an IC50 value of 50μM (or 14.3μg/mL). That was higher than a brazilein-containing fraction, which was reported previously by our group to have an IC50 value of 68μg/mL against the same cell. Cell cycle analysis showed that cells treated with brazilin were accumulated at the G2/M phase in a dose-dependent manner. Furthermore, cells treated with a combination of brazilin and doxorubicin was accumulated at the G2/M phase and sub G1 phase. Cells accumulation at sub G1 phase indicates that the cells undergo apoptosis. Our data of S-A-β-galactosidase assay showed that cells treated with 1/4IC50, 1/2IC50, and IC50 brazilin had lower senescent cells compared to the untreated cells. The morphology of cells treated with IC50 (50μM) brazilin changed. The cells shape became rounded, cells were shrinkage and detached from the well plate, indicating that cells may undergo apoptosis. These results suggested that brazilin was cytotoxic towards T47D cells and its combination with dox potentially induced apoptosis and decreased cell senescence. The ability of brazilin to decrease cell senescence provides new insight of utilization of C. sappan or its constituents, particularly brazilin, as anti-ageing.

Abstract

Despite causing many side effects, doxorubicin (Dox) is still one of breast cancer drug of choice. Thus, combination of chemotherapy is developed in order to decrease doxorubicin regimen dose. The aim of this research is to examine the combination effect of doxorubicin (dox) and areca extract (AE) on T47D human breast cancer cells. The cytotoxic activity was determined using MTT assay. The combination index (CI) of the combination treatment was calculated to determine the effects (synergistic, additive or antagonistic). The combination application of dox (6-22nM) and AE (8-30µg/ml) on T47D cells showed synergistic (CI<0.9) or additive effect (CI=0.9-1.1). The effective combination of dox-AE was 6 nM - 8 µg/ml on CI<0.5. Apoptosis induction of AE solely and its combination with dox was then observed using double staining method. Moreover, expression of Bax and caspase-3 protein which mediated apoptosis, were observed using immunocytochemistry. Combination of AE and Dox increased expression of Caspase-3 but did not increase expression of Bax. This result showed AE increase the effectiveness of doxorubicin against T47D cells.Keywords: Breast cancer, doxorubicin, areca extract, T47D cells
