Abstract

Physalis angulata was known for its pharmacological potential, including antioxidant activity, yet the specific bioactive compounds responsible for enhancing endogenous antioxidant enzymes, such as superoxide dismutase 1 (SOD 1), remained unclear. This study aimed to identify and evaluate the active compounds of P. angulata as natural SOD 1 activators using an In silico molecular docking approach. Forty-nine ligands derived from the active constituents of P. angulata were screened based on Lipinski’s Rule of Five and ADMET properties. Molecular docking was performed using the SOD 1 protein (PDB ID: 5YTO), and docking validation yielded an RMSD value of 0.005 Å. Among the test ligands, withanolide exhibited the most favorable binding energy (−7.011 kcal/mol) and the lowest inhibition constant (7.0 pM), forming strong interactions with key catalytic residues of the enzyme. These findings indicated that withanolide had promising potential as a natural SOD 1 activator, providing a basis for future antioxidant drug discovery.

Abstract

Ilmu forensik veteriner belum mendapat perhatian yang memadai di Indonesia, sehingga perlu ditingkatkan pengembangannya. Penelitian ini bertujuan mempelajari ilmu forensik veteriner melalui histopatologi hati ayam broiler 48 jam pasca kematian. Ayam broiler sebanyak 75 ekor berumur 7 hari dieutanasia dan dibagi menjadi 25 kelompok berdasarkan jam nekropsi pasca-eutanasia (n=3). Kadaver ayam dinekropsi setiap 2 jam postmortem, organ hati dikoleksi untuk dibuat potongan histopatologi dan diwarnai dengan Hematoksilin-Eosin (HE). Histopatologi hati evaluasi dan hasil yang didapat dianalisis menggunakan software ImageJ versi 1.53a. Hubungan peubah histopatologi dengan waktu postmortem dianalisis dengan metode Pearsons. Hasil penelitian menunjukkan bahwa pembusukan dimulai pada jam ke-18 post mortem yang ditandai dengan jumlah inti sel hepatosit, jam ke-20 ditemukan bakteri pembusuk, dan jam ke-22 terjadi peningkatan jarak antar hepatosit. Berdasarkan nilai korelasi Pearson, jumlah inti sel hepatosit, jarak antar hepatosit dan keberadaan bakteri pembusuk mempunyai hubungan kuat hingga sangat kuat dengan waktu postmortem sehingga hasil ini dapat menjadi parameter penentu waktu kematian (Post Mortem Interval/PMI) pada hewan.

Abstract

This study aims to study the effectiveness of single placental stem cell therapy or cardiomyocyte combination in pigs experiencing myocardial infarction in terms of urea, creatinine and kidney organ histopathology values. A total of 9 pigs were divided int o three groups: without therapy (K1), single placental stem cell therapy (K2), and cardiomyocyte coculture combination therapy (K3). All pigs underwent circumflex artery ligation of the proximal coronary artery branch to stimulate cardiac ischemia and therapy was given after myocardial infarction and ST-elevation were formed. The pigs were then treated for eight weeks, euthanized and necropsied for kidney organ removal. The re sults showed a significant decrease in urea and creatinine values (P0.05) in K2 and K3 as compared to K1. Histopathology results showed a decrease in glomerular atrophy values (K2: 10.260.93 and K3: 12.441.21), tubular necrosis (K2: 13.673.76 and K3: 17.230.55), and tubular dilation (K2: 16.361.26 and K3: 18.031.76) and these values were significantly different than those observed in K1. It was concluded that the administration of placental stem cell therapy or combined with cardiomyocyte coculture could reduce urea, creatinine values, and improve kidney tissue histopathologically.

Abstract

Agarwood leaves (Aquilaria malaccensis), a non-timber forest products, shows significant potential as a source of antidiabetic compounds. This study aims to evaluate the antidiabetic activity of agarwood leaves and their cytotoxicity on pancreatic beta-cells, as well as predict their compound bioactivity through an in silico approach. The leaves were extracted using ethanol, water, and a mixture of ethanol–water with the assistance of ultrasound irradiation. The extracts were then tested in vitro for their antidiabetic potential by assessing their ability to inhibit the alpha-glucosidase enzyme and their effect on insulin secretion, as well as their cytotoxicity on BRIN-BD11 pancreatic beta-cells. The phytocompounds in the extract were identified using liquid chromatography-mass spectrometry, and their binding behavior was studied by in silico molecular docking. Among the three, the ethanol–water extract showed the highest extraction yield. Cytotoxicity assays revealed that the ethanol–water extract was cytotoxic at high concentrations (1000 µg/mL), but safe at lower concentrations. The alpha-glucosidase inhibition was relatively weak. Nevertheless, the extracts significantly stimulated insulin secretion in BRIN-BD11 cells up to fivefold compared to untreated cells. In silico studies indicated that xanthone glycoside, flavonoid glycoside, and coumarin compounds exhibit strong binding affinities to multiple insulin-secretion-related proteins. These findings suggest that agarwood leaf extract, particularly ethanol–water extract, possesses promising antidiabetic activity through an insulinotropic mechanism.
