Abstract

Bay leaves (Syzygium polyanthum) contain the flavonoid quercetin which can be used as an antihyperlipidemic drug. The development of antihyperlipidemic drug formula in the form of fast disintegrating tablet (FDT) is needed for patients who experience dysphagia. FDT preparations require an optimal super disintegrant concentration to produce a good drug formula. This study aims to develop the FDT formula of bay leaves extract using the super disintegrant croscarmellose sodium (CCS) intra and extra-granular. FDT formulation using the wet granulation method with variations of CCS concentrations; F1: 2%, F2: 3.5%, and F3: 5% for extra granular, and 2% for intra granular. The formulation process, in-process control (IPC) granules, weight uniformity tests, and various physical properties tests of tablets were carried out. Data were statistically analyzed using one way ANOVA test (α=95%). The results of statistical tests of IPC granules, uniformity of weight, and tablet size of all FDT formulas were not significantly different (p>0.05). The CCS concentration for extra granular significantly affected the wetting time, disintegration time, hardness, and the value of friability percentage of FDT (p<0.05). The combination of intra and extra-granular CCS (2%:5%) gave the most optimum physical properties of bay leaf extract FDT.

Abstract

BACKGROUND: The 4T1 cells, a triple-negative breast cancer (TNBC) cell line, exhibit high malignancy and metastatic potential. As a primary treatment for TNBC, doxorubicin has limitations, including drug resistance mechanisms and severe side effects such as cardiotoxicity. Pentagamavunone-1 (PGV-1) exhibits antiproliferative and antimetastatic effects, induces prometaphase arrest, triggers cell senescence, and enhances reactive oxygen species (ROS) modulation, which may help overcome doxorubicin resistance. The selective cytotoxicity of PGV-1 against cancer cells suggests that it has a role in reducing systemic toxicity. Therefore, in this study, the anticancer effects of doxorubicin combined with PGV-1 was investigated.METHODS: Monolayer/2D and spheroid/3D models of 4T1 cells were used to assess the effects of PGV-1, doxorubicin, and their combination. MTT assay was used to evaluate the cytotoxicity, colony formation assay was used to measure persistent antiproliferative effects, and spheroid volume analysis was performed to assessed tumor growth inhibition. Senescence-associated beta-galactosidase (SA-β-gal) assay determined cellular senescence.RESULTS: The combination of PGV-1 and doxorubicin significantly enhanced cytotoxicity, with IC50 values of 0.57 µM and 4.88 µM, respectively (p=0.000). A strong synergistic effect was observed, leading to persistent suppression of cancer cell proliferation and an 80% reduction in colony formation (p=0.007). In the 3D spheroid model, combination treatment significantly reduced spheroid volume (p=0.002) more effectively than monotherapy, indicating superior growth inhibition and cytotoxicity. It also increased SA-β-gal, the senescence marker (p=0.010).CONCLUSION: The combination of PGV-1 and doxorubicin demonstrated potent anticancer effects in 4T1 monolayers and spheroid models by enhancing cytotoxicity and inducing cellular senescence. This combination confirmed its potential as a more effective therapeutic strategy.KEYWORDS: 3D spheroid, 4T1 TNBC cell, doxorubicin, pentagamavunon-1, PGV-1, senescence

Abstract

Doxorubicin (DOX) and cisplatin (Cis), non-specific chemotherapeutic agents used for hepatocellular carcinoma (HCC), are frequently combined with synthetic or natural agents to enhance their cytotoxic effects. Citrus sinensis peel extract (CPE) serves as a natural source of flavonoids, including sinensetin (SIN), which has the potential to increase the efficacy of DOX and Cis. This study aimed to observe the effect of CPE and SIN one of CPE compounds, in enhancing liver cancer cell susceptibility to doxorubicin and cisplatin. The assays conducted in this study included a phytochemical analysis of CPE using TLC, cell viability assays against HepG2 cells using MTT assay in both single and combination forms, and cell viability assays on Vero cells. The result confirmed the presence of SIN as one of the compounds in CPE. Both CPE and SIN, when used individually, exhibited moderate cytotoxic effects on HepG2 cells with IC50 of 101.09 μg/mL and 83.13 μM, respectively, while showing no cytotoxic effect on Vero cells. Cis demonstrated significant cytotoxicity against HepG2 cells with an IC50 of 7.86 μM. DOX exerted a strong cytotoxic effect on both HepG2 and Vero cells, with the IC50 of 2.52 μM and 13.98 μM. It was observed that CPE was able to synergistically enhance the cytotoxic effects of DOX, and SIN synergistically increased the cytotoxicity of Cis, particularly against HepG2 cells, with CI<1.0.Keywords: CPE, SIN, Cisplatin, Doxorubicin, HCC.

Abstract

Chemotherapeutic agents for breast cancer such as doxorubicin can attack normal cells as the side effects. Chromolaena odorata L. and its chemical content, sinensetin, have potential anticancer  and  antioxidant  properties.  The  objective  of  this  research  is  to  examine  the anticancer properties of C. odorata leaves extract and sinensetin on 4T1 triple negative breast cancer (TNBC) cells combined with doxorubicin. The MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5 diphenyltetrazolium  bromide)  assay  on  4T1  cells  was  used  to  determine  the  IC50 and the Combination  Index  (CI)  of  the  two  agents  in  combination.  Washing  out the  treatment  and determining  the  cells  viability  after  a  few  days  was done  to evaluate  the  persistence  of the  effects  to  cancer  cells.  Chromolaena odorata  extract  (COE)  obtained  was  proven  to contain  sinensetin  which  gave  a positive  signal  on  the  chromatogram.  COE  and  sinensetin were  moderately  cytotoxic  to  4T1  cells  with  IC50  value  of  53  μg/mL  and  58  μM  (21.6 μg/mL), respectively. Both compounds were synergist (CI<0.7) to strong synergist (CI<0.3) when combined with doxorubicin (IC50 90 nM = 0.05 μg/mL). COE and sinensetin exhibited moderate and not cytotoxic against Vero cells with IC50 values of 60 μg/mL and 243 μM (90.43 μg/mL), respectively. Both COE and sinensetin showed selectivity index values of >1 (1.13 and 4.19, respectively).  Moreover,  the  cytotoxic  effects  of  COE  on  4T1  cells  was  persisted  until  48  h after  removing  COE  from  the  medium,  indicating  the  tumor-suppression  potency  of  COE. Our findings strengthen the scientific basis of C. odorata leaves extract to be developed as a co-chemotherapeutics agent for doxorubicin on TNBC.Keywords: Chromolaena odorata L., breast cancer cells, doxorubicin, co-chemotherapy, kidney cells.

Abstract

Hepatocellular carcinoma is the most common type of liver cancer. Curcuminoids are natural polyphenol compounds abundant in Curcuma heyneana ethanolic extract (CHE) and are known to inhibit breast and cervical cancer cell proliferation. Based on previous research, curcuminoid compounds have been studied to inhibit the growth of the liver cancer cell model, HepG2. This study aims to examine the potential of CHE as a chemopreventive agent in liver cancer using JHH-4 cell as a model. CHE was obtained by maceration method using ethanol which was then identified for its phytochemical profile using thin layer chromatography (TLC). Then TLC results were quantified to calculate the levels of compounds present in the CHE based on spot intensity with ImageJ software. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) antioxidant assay was conducted to determine the radical scavenging activity of CHE. Cytotoxic activity of CHE on JHH-4 liver cancer cells was tested by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Extraction produces a yield of 10.2 %w/w. CHE contains 4.52 %w/w curcuminoid compound consisting of 0.49 %w/w curcumin, 3.21 %w/w demethoxycurcumin, and 0.82% w/w bisdemethoxycurcumin. CHE exhibited antioxidant activity with an IC50 value of 378.96 μg/mL, meanwhile ascorbic acid as a positive control has an IC50 value of 8.49 μg/mL. Cytotoxic activity of CHE on JHH-4 cells is characterized by an IC50 value of 16.62 μg/mL which is classified as having strong cytotoxic activity. This study concluded that CHE has the potential to be developed as a chemopreventive agent in liver cancer.Keywords: liver cancer, hepatocelullar carcinoma, Chemopreventive, antioxidant,Curcuma heyneana.
