Abstract

Endophytic bacteria are beneficial microorganisms that interact with host plants without causing disruption or damage to the host. Some studies suggest that certain endophytic bacteria can produce chemical compounds that have an effect on health, especially endophytic bacteria isolated from medicinal plants. Green betel (Piper betle L.) is a medicinal plant that has been used for years and has many benefits. The purposes of this study are to isolating and screening of endophytic bacteria from green betel against four pathogenic bacteria (Staphylococcus aureus, Escherichia coli, Bacillus cereus and Salmonella enteritidis). The number of endophytic bacteria that has been isolated are 14 isolates. Based on the screening results, three isolates of endophytic bacteria have potential activity (characterized by the formation of inhibition zone) against S. aureus. The inhibition zone may indicate that those isolates produce compounds that have antibacterial effects. Those isolates are AS1, BS1 and BS2. The biggest inhibition zone showed by BS1, so it can be concluded that BS1 is the most potential isolate as a novel source of antibacterial compound.

Chitosan is a chitin derivative, which is known to have antimicrobial properties. These properties make chitosan have a potential as a cosmetics ingredient. This study aimed to determine the safety of anti-acne cream with the addition of chitosan from shells of antique ark shells (Anadara antiquata Linn.) from heavy metal and microbial contamination. Heavy metal content was tested with Atomic Absorption Spectrophotometry (AAS). Microbial contamination of the cream base and 5% chitosan cream was determined by measuring the total plate count (TPC) and yeast mold number (YMN) using the pour cup method. The levels of lead and mercury in shells met the standards with values ​​of 1.78 mg/kg and <0.004 mg/kg, respectively. The TPC values ​​for cream base and 5% cream also met the standards with successive values ​​of 8.3x102 cfu/mL and 7.2x104 cfu/mL, while the YMN values ​​did not meet the standards with consecutive values ​​of 2.2x104 cfu/mL and 1.4x104 cfu/mL. Cream with the addition of 5% chitosan showed lower TPC and YMN values ​​compared to cream base (control). Cream preparations with the addition of chitosan do not meet BPOM Indonesia's safety standards for YMN values.

Abstract

Betalaktamase adalah enzim yang mengkatalisis hidrolisis antibiotik Betalaktam sehingga dapat menyebabkan resistensi antibiotik. Bakteri yang dilaporkan dapat menghasilkan enzim Betalaktamase antara lain Klebsiella pneumoniae, Escherichia coli, Enterobacter sp., Salmonella sp., Proteus sp., Serratia marcescens, Shigella dysenteriae, Pseudomonas aeruginosa, dan Burkholderia cepacia. Saat ini resistensi terhadap antibiotik golongan Betalaktam semakin meluas. Penggunaan antibiotik ini seringkali dikombinasikan dengan inhibitor Betalaktamase seperti asam klavulanat, sulbaktam, dan tazobaktam untuk meningkatkan efisiensi terapi. Antibiotik betalaktam adalah antibiotik spektrum luas yang banyak menjadi pilihan untuk terapi. Oleh karena itu, pencarian kandidat inhibitor Betalaktamase untuk mencegah resistensi perlu dilakukan. Pada penelitian ini dilakukan penapisan senyawa polifenol sebagai inhibitor enzim Betalaktamase dengan metode penambatan molekuler. enapisan terhadap 112 senyawa polifenol dari database menghasilkan 27 senyawa yang memiliki energi bebas ikatan yang lebih baik dari ligan alami. Prediksi drug-likeness berdasarkan aturan Lipinski terhadap 27 senyawa tersebut menghasilkan 6 senyawa yang berpotensi, yaitu trans-resveratrol 3-O-glucuronide, apigenin-7-O-glucoside, cis-resveratrol 4'-sulfate, sulfuretin, dan apigenin. Berdasarkan visualisasi interaksi ligan-reseptor, keenam senyawa tersebut berinteraksi dengan residu katalitik enzim betalaktamase. Energi bebas ikatan terbaik ditunjukkan oleh trans-resveratrol 3-O-glucuronide sebesar -8,1 kkal/mol dan prediksi Ki sebesar 1,137 MikroM. Berdasarkan studi penambatan molekuler dan prediksi drug-likeness, 6 senyawa polifenol yang berpotensi tersebut dapat dilanjutkan untuk penelitian lebih lanjut.

Abstract

The potential of black soldier fly (Hermetia illucens (Linnaeus), BSF) maggots as the source of biopharmaca, has not been extensively studied. This research aimed to identify bioactive compunds in BSF maggot extract that potentially activate antioxidant signaling mechanism. BSF maggots fed with vegetable waste were extracted based on maceration method with water, methanol, and acetone as solvents. Forty bioactive compounds were identified by liquid chromatography-mass spectrometry: 15 were in the aqueous extract, 13 were from methanolic extract, and 12 were in the acetone extract. Most of those compounds (90%) were having high bioavailability score (= 0.55 or more) and relatively low toxicity (500 mg/Kg<LD50<5000mg/Kg BW). Molecular docking predicted that there were 26 bioactive compounds potential to activate cellular antioxidant signaling through activation of NRF2 transcription factor, better than the commercial NRF2 activator. The aqueous extract compound with PubChem CID: 73775828 was the best one that inhibited NRF2 signaling by binding to Keap-1 protein (PDB ID: 6FFM) with Gibbs free energy (ΔG) = -6.08 Kcal/mol and dissociation constant (Kd) = 3.58 í— 10-5 µM. Whereas inhibition of inflammation via NF-kappa B signaling was shown by an aqueous extract compound verpacamide A which bound inhibitor NF-kappa B kinase (IKK2) (PDB ID: 4KIK) with ΔG = -5.024 kcal/mol; Kd = 0.207 í— 103 µM. This potency was better than that of aspirin. In conclusion, BSF maggot extracts are source of biopharmaca with potential cellular antioxidant and anti-inflammatory activity.

Abstract

Kesehatan masyarakat di pedesaan Indonesia seringkali terhambat oleh pola konsumsi pangan yang tidak seimbang, dengan ketergantungan tinggi pada karbohidrat dan asupan protein nabati yang kurang optimal. Salah satu solusi potensial adalah peningkatan konsumsi sari kedelai, yang kaya akan protein, vitamin, dan mineral. Sari kedelai dapat membantu memperbaiki gizi dan mengurangi risiko penyakit degeneratif. Desa Sukamaju di Kecamatan Cigudeg, Kabupaten Bogor, memiliki potensi untuk mengembangkan produksi sari kedelai, tetapi pemanfaatannya belum maksimal. Program ini bertujuan untuk meningkatkan gizi masyarakat dan memberdayakan ekonomi lokal melalui pendirian rumah produksi sari kedelai. Kegiatan melibatkan kader Posyandu dan PKK melalui sosialisasi dan pelatihan. Metode yang digunakan meliputi pengumpulan data melalui kuisioner pre-test dan post-test untuk menilai pengetahuan sebelum dan setelah pelatihan. Hasil pelatihan menunjukkan peningkatan pemahaman masyarakat tentang sari kedelai, meskipun awalnya pengetahuan mereka terbatas. Program ini berhasil meningkatkan minat dan pengetahuan mengenai sari kedelai, serta berpotensi untuk menjadi model bagi desa lain. Kesimpulannya, program ini memberikan manfaat ganda dengan meningkatkan gizi masyarakat dan mendukung ekonomi lokal, meskipun masih ada tantangan dalam mendorong produksi dan konsumsi sari kedelai secara mandiri.

Abstract

Red ginger (Zingiber officinale var. rubrum) is traditionally recognized for its medicinal properties, largely due to its antioxidant potential attributed to secondary metabolites such as flavonoids. This study aimed to evaluate the total flavonoid content and antioxidant capacity of ethanol and water extracts of red ginger from Sukabumi, specifically the Jahira 1 variety, as well as identify bioactive compounds. Extraction was carried out using the maceration method. The total flavonoid content was determined using the aluminium chloride colorimetric method, while the antioxidant capacity was assessed via the ferric reducing antioxidant power (FRAP) assay. Results showed that the ethanol extract had higher total flavonoid content and antioxidant capacity, with values of 5.99 mg quercetin equivalent (QE)/g and 473.93 µM Trolox equivalent (TE)/g, respectively. In contrast, the water extract exhibited 3.73 mg QE/g and 206.75 µM TE/g. Further LC-MS/MS analysis of the ethanol extract identified 26 compounds, including phenolics and terpenoids, which contribute to the antioxidant capacity of red ginger from Sukabumi.

Abstract

Dental caries are caused by plaque formation resulting from biofilm accumulation on tooth surfaces. The bacterium Streptococcus mutans plays a crucial role in biofilm formation, partly through the production of glucosyltransferase, which catalyzes biofilm synthesis. Flavonoids are secondary metabolites commonly found in plants, known for diverse biological properties, including antibiofilm effects. This study aimed to screen the potential of flavonoid compounds as antibiofilm agents through inhibition of glucosyltransferase using an in-silico approach. A total of 87 flavonoid compounds obtained from the ZINC database were evaluated via molecular docking methods. Screening results based on binding free energy (ΔG) values, analyzed using the PyRX-Virtual Screening Tool, indicated that 36 compounds had potential to inhibit glucosyltransferase. Further molecular docking using AutoDock Vina identified nine compounds with ΔG values more favorable than the natural ligand of glucosyltransferase (maltose). Molecular interaction analysis using LigPlot+ and PyMOL revealed that taxifolin, gallocatechin, and sakuranetin interacted with three catalytic residues of the enzyme, whereas the remaining six compounds interacted with two catalytic residues. Liquiritigenin exhibited the lowest ΔG (-7.0 kcal/mol) and an inhibition constant (Ki) of 7.39 µM, indicating high affinity for glucosyltransferase. This compound formed two hydrogen bonds and four hydrophobic interactions, engaging two catalytic residues of the enzyme, Asn481 and Trp517. These findings highlight the potential of flavonoids as antibiofilm agents via glucosyltransferase inhibition. Further experimental validation through in vitro studies is necessary to confirm these in-silico findings.
