Abstract

As one of the leading causes of death in worldwide, cervical cancer requires the effective therapies to reduce its mortality rate. One of the chemotherapy agents that frequently used in the treatment is cisplatin. However, due to drug resistance and its side effects, an agent that can be combined with cisplatin is needed. Parijoto fruit (Medinilla speciosa Reinw.ex.Bl) contains secondary metabolites compounds that have potential as anticancer. The study aims to determine the cytotoxic effect of methanol extract of Parijoto fruit calculated from the IC50 value and the synergicity of the combinational treatment with cisplatin evaluated from the Combination Index (CI) value and its cell viability by using MTT assay. Results showed that methanol extract of Parijoto fruit (MEP) performed cytotoxic effect on HeLa cell line with IC50 of 209.6 μg/mL while the value of IC50 of cisplatin against HeLa cells amounted to 12.8 μg/mL. The combination of 26.205 ppm (1/8 IC50) of MEP and 1.601 ppm (1/8 IC50) of Cisplatin performed synergistic effect on HeLa cell line with the CI value of 0.69. From the above results, it can be concluded that MEP is potential as co-chemotherapy agent based on the synergistic cytotoxicity effect with cisplatin.Keyword: cytotoxic, Medinilla speciosa, cisplatin, co-chemotherapy, MTT

Abstract

Parijoto (Medinilla speciosa, Reinw. ex. Bl.), a tropical plant native to Southeast Asia, contains flavonoids, tannins, and saponins, which have the potential as an anticancer. Gold nanoparticle-based drug formulations are applied to increase the anticancer effectiveness of herbal medicines. The compounds in the stalk of parijoto have the potential to be bioreductor in the biosynthesis of gold nanoparticles. This study aims to determine the physicochemical characterization, cytotoxic activity, and expression of protein caspase-9 after treatment with nanogold parijoto (AuNPs-PR) on HeLa cell. The nanogold biosynthesis process was done by reacting 1 mM HAuCl4 with parijoto aqueous extract (EP). Physicochemical characterization measure of particle size, Polydisperse Index (PdI), and zeta potential of AuNPs-PR was carried out using a particle size analyzer. The cytotoxic effect and viability cell of AuNPs- PR were carried out using the MTT assay. The expression of caspase-9 was observed by immunocytochemistry assay. Physicochemical characterization of AuNPs-PR shows that the particle size value is 160.8 nm with PdI and zeta potential values of 0.430 and -4.56 mV respectively. In the MTT assay, both AuNPs-PR and EP demonstrated a reduction in the viability of Hela cells after 24 h in a dose-dependent manner, yielding IC50 values of 3.28 μg/mL and 19.22 μg/mL, respectively. AuNPs-PR and EP showed low cytotoxic activity against Vero normal cells, with IC50 values of over 500 μM. Further, the immunocytochemistry assay indicated that there was upregulation of caspase-9 by their expression. These results indicate that AuNPs-PR could effectively induce apoptosis in HeLa cells by upregulating caspase-9.Keywords: caspase-9, HeLa cells, MTT, nanogold, parijoto.

Abstract

Cisplatin (Cisp) is a non-specific chemotherapeutic agent for breast cancer. Hesperetin (HST), a flavanone found in various citrus fruits, exhibits bioactive properties, functioning as an antioxidant, anti-inflammatory, and anticancer agent. The objective of this research was to investigate the potential of HST as a co-chemotherapeutic agent in conjunction with Cisp, specifically focusing on its cytotoxic effects against 4T1 triple-negative breast cancer cells and senescence modulatory effect on Vero normal kidney cells. The cytotoxic effect and viability cell of HST were evaluated through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. In addition, the effect of cellular senescence inhibition on the Vero cell line was measured using senescence-associated β-galactosidase (SA-β-gal) staining. In the MTT assay, both HST and cisplatin demonstrated a reduction in the viability of 4T1 cells in a dose-dependent manner, yielding IC50 values of 498 μM and 2 μM, respectively. The co-treatment of HST and cisplatin showed an increase in sensitivity of the 4T1 cells with a combination index of <1. HST showed low cytotoxic activity against Vero cells, with IC50 values of over 500 μM. HST decreased cellular senescence induced by cisplatin exposure on Vero cells. These results indicated that HST in co-treatment with cisplatin decreased 4T1 cell viability synergistically. HST independently reduces the cellular senescence of normal cells. Consequently, HST holds promise for potential development as a co-treatment agent in combination with cisplatin for breast cancer cells, and it may also serve as an alternative for counteracting senescence in healthy tissues.Keywords: cytotoxic, senescence, hesperetin, cisplatin, breast cancer.

Abstract

Bay leaves are used as food flavoring and also have medicinal properties. They may have cytotoxic effects derived from natural ingredients. The low efficacy of the therapy with an adequate dose preparation of the plant extract is due to its low solubility and oral bioavailability that is less than the maximum. Hence, this study aimed to improve the solubility and oral bioavailability of the extract mainly for the chloroform extract of leaves that are not soluble in water by preparing a self-nanoemulsifying drug delivery system (SNEDDS). Then, the potential cytotoxic effects of the SNEDDS of bay leaves were determined by calculating the value of IC50 on the T47D cell line. The cytotoxic effect of the SNEDDS of bay leaves was determined using an MTT assay, and the findings were read using an ELISA reader. Data analysis is calculated via linear regression methods by using Microsoft Excel software. The results showed that the SNEDDS of bay leaves performed cytotoxic effects on the T47D cell line with IC50 138 μg/mL. The results showed that the optimal composition formula SNEDDS, namely, Tween 20:PG:oleic acid = 2.25:2.25:0.5 in 5 mL SNEDDS preparation, which had a value of transmittance of 83.81% with emulsification time was less than 5 min; the average droplet size was 165.5 nm, and the zeta potential was −0.4 mV. The data analysis showed that the cytotoxicity effect of the SNEDDS of bay leaves is included in the moderate cytotoxic category.Keywords: Bay leaf, optimization, nanoemulsi, cytotoxicity.
