Abstract

Lactobacillus plantarum S34 dilaporkan mempunyai aktivitas antibakteri yang terkait dengan produksi bakteriosin. Bagian dari gen yang menyandikan salah satu lokus bakteriosin yang diproduksi oleh L. plantarum S34, disebut dengan plantarisin W (plnW), diamplifikasi dari plasmid dan dikloning menggunakan sistem vektor pGEM®-T Easy ke dalam Escherichia coli DH5?. Sekuens nukleotida plnW (± 405 pb) diidentifikasi sebagai protein integral membran. Lebih lanjut, plnW diekspresikan secara heterologus sebagai fusi protein dengan His(6)-tag tioredoksin menggunakan vektor ekspresi pET-32a(+) ke dalam E. coli BL21 (DE3) pLysS. Protein fusi rekombinan plnW terdapat dalam sitoplasma sel, tetapi selain fraksi terlarut terdapat juga fraksi tidak terlarut berupa badan inklusi. Purifikasi parsial dilakukan menggunakan kromatografi afinitas ligan Co2+ untuk fraksi terlarut dan metode elektroelusi gel poliakrilamid untuk fraksi tidak terlarut. Massa molekul berukuran kurang lebih 33 kDa terdeteksi berdasarkan pemisahan SDS-PAGE dan dikonfirmasi dengan Western blot sebagai protein fusi rekombinan plnW. Protein yang sudah terpurifikasi bermanfaat untuk mengetahui kaitan antara struktur dan fungsi bakteriosin.

Abstract

Nontuberculous mycobacteria (NTM) are environmental microorganisms, also known as opportunistic pathogens, found in patients with pulmonary tuberculosis. The emergence of antibiotic resistance is increased by prolonged antibiotic treatment for NTM infections. Therefore, alternative sources of new antibiotics are essential for the treatment of NTM infections. A marine actinobacterium, Streptomyces sp. BTA 1-131, isolated from a marine sponge, Melophlus sarasinorum, has been reported as a potential source of antibacterials and anticancer agents. The present study aimed to investigate the potential of Streptomyces sp. BTA 1-131 against two NTMs: Mycobacterium smegmatis and Mycobacterium fortuitum. Streptomyces sp. BTA 1-131 was fermented in three cultivation media (SYP, ISP2, and YS), and the secondary metabolites were extracted using methanol. The bioactivity screening showed inhibition of all methanolic extracts against the growth of M. smegmatis and M. fortuitum. The methanolic extract, which could inhibit both mycobacteria, was a crude extract derived from SYP liquid medium fermentation. The isolated compounds in this study were preliminarily identified using thin-layer chromatography (TLC). The TLC results showed different potential compounds in the crude extracts of Streptomyces sp. BTA 1-131 also highlighted the impact of the fermentation medium on the production of metabolites from Streptomyces. This study also added knowledge about the importance of the Indonesian marine actinobacterium Streptomyces sp. BTA 1-131 as a promising producer of anti-NTM compounds.

Abstract

Cancer has a high prevalence and mortality in the world. Cancer treatment is still hampered by high levels of side effects, drug resistance and the lack of affordable prices for anticancer drugs. It is necessary to develop new anticancer drugs to help overcome this problem. One of the plants that has the potential to be developed as an anticancer drug is Sungkai (Peronema canescens Jack). This study aims to determine the cytotoxic activity of sungkai leaf and identify its metabolomic profile. The sungkai leaves were macerated for 24 hours with 96% ethanol. Metabolomic profiles were analyzed with Ultra High-Performance Liquid Chromatography-High Resolution Mass Spectrometry (UHPLC-HRMS). Chemical structure identification was performed by MS-DIAL and MS-FINDER platforms. The ethanol extract of sungkai leaves was analyzed for its cytotoxic activity using the MTT test on A549 lung cancer cells and its selectivity on normal HDFa fibroblast cells. The ethanol extract of sungkai showed IC50 105,21 µg/mL on A549 cells and no cytotoxic activity against normal HDFa cells. Based on the metabolomic analysis, 7 furano terpenoid compounds were detected in the ethanol extract, namely peronemin A2; A3; B1; B2; B3: C1; and D1 along with other compounds. In conclusion, the ethanol extract of P. canescens leaves has cytotoxic and selective activity against A549 lung cancer cells, and potential to be further developed as an anticancer drug candidate. Peronemins and other substances like flavonoids and polyphenols may be linked to the cytotoxic properties of sungkai leaves
