Abstract

COVID-19 pandemic caused by SARS-CoV-2 is a challenge for researchers to find effective drugs for this disease. Previous research had identified the role of Mpro, TMPRSS2, RdRp, and ACE2 which were useful as promising drug targets to inhibit SARS-CoV-2. This study aims to identify the potential compounds derived from Ginkgo biloba as potential SARS-CoV-2 inhibitors using a molecular docking study. A total of twenty-one compounds of Ginkgo biloba and comparative drugs were used in this study. The materials were downloaded from rcsb for protein targets and pubchem for comparative drugs and compounds. In this study, Lipinski rule of five using Swiss ADME web tool was used. Moreover, toxicity analysis using admetSAR 2.0 online test also used to predict toxicological profile of compounds. Dockings were carried out on Mpro, TMPRSS2, RdRp, and ACE2 protein targets by AutodockTools 1.5.6 and Autodock Vina. The visualization of molecular interaction was carried out by Discovery Studio v16. Nine compounds met the criteria as drug-like components and were safe. Docking results showed that ginkgolide-C and bilobetin showed strong molecular interactions to all protein targets compared to the comparative drugs and other compounds. In RdRp, ginkgolide-C showed the highest binding energy with -12.7 kcal/mol. Moreover, in TMPRSS2, ACE2 and Mpro, bilobetin also showed the highest binding energy with -12.7, -9.7 and -10 kcal/mol, respectively. Ginkgolide-C and bilobetin have the potential to be developed as SARS-CoV-2 inhibitors. Therefore, in vitro and in vivo investigations are needed to bring these compounds to the clinical setting.

Abstract

Pendahuluan: Penyakit Alzheimer adalah penyakit neurodegeneratif yang menyebabkan gangguan progresif pada fungsi perilaku dan kognitif. Penyakit ini merupakan jenis demensia yang paling umum terjadi dengan prevalensi yang meningkat setiap tahunnya. Patofisiologi kompleks yang dimiliki penyakit ini menyebabkan belum adanya pengobatan yang efektif untuk penyakit Alzheimer. Tinjauan literatur ini bertujuan untuk meninjau lebih lanjut mengenai potensi Rabies Viral Glycoprotein (RVG)-modified exosomes yang berasal dari Bone Marrow Mesenchymal Stem Cell (BMMSC) melalui aktivasi mikroglial otak yang dapat mereduksi Aβ sebagai terapi kuratif terkini pada penyakit Alzheimer. Metode: Literatur dicari menggunakan situs pencari seperti Google Scholar, Science Direct, ResearchGate, dan NCBI. Kriteria inklusi dan eksklusi digunakan untuk mengeliminasi literatur yang tidak berkaitan sehingga diperoleh 24 literatur. Pembahasan: BMMSC dapat meringankan neuropatologi, penurunan memori, dan defisit perilaku. Selain itu, BMMSC yang ditransplantasikan dapat menghambat kematian sel terkait Aβ dan tau. Sementara itu, terjadi peningkatan regulasi ekspresi sitokin antiinflamasi (IL-10 dan IL-4) dan penurunan regulasi sitokin proinflamasi (TNF-a dan IL-1β). Studi ini menunjukkan bahwa penggunaan BMMSC yang diturunkan dari eksosom yang dimodifikasi RVG lebih baik daripada BMMSC yang diturunkan dari eksosom saja untuk meningkatkan fungsi kognitif pada mencit APP/ PS 1. Kesimpulan: RVG-eksosom derivat BMMSC dapat menghambat kematian sel dengan mengurangi akumulasi Aβ dan tau, menyeimbangkan faktor inflamasi otak, serta meningkatkan fungsi memori dan kognitif. RVG-eksosom BMMSC berpotensi sebagai terapi mutakhir penyakit Alzheimer serta penyakit neurogeneratif lainnya. Saran: Dibutuhkan penelitian lebih lanjut terkait mekanisme molekular, dosis, dan efek samping terapi RVG-eksosom derivate BMMSC pada penyakit Alzheimer.

This disease is the most common type of dementia with an increasing prevalence every year. Due to its complex pathophysiology, there is no effective treatment to date for Alzheimer’s disease. This literature review aims to further review the potential of Rabies Viral Glycoprotein (RVG)-modified exosomes from Bone Marrow Mesenchymal Stem Cells (BMMSC) through microglial activation in the brain which can reduce Aβ as the latest curative therapy in Alzheimer's disease. Method: Literature is searched using search engines such as Google Scholar, Science Direct, ResearchGate, and NCBI. Inclusion and exclusion criteria were used to eliminate unrelated journals so that 24 journals were obtained. Discussion: BMMSC can alleviate neuropathology, memory decline, and behavioral deficits. In addition, transplanted BMMSC could inhibit Aβ and tau-associated cell death. Meanwhile, there is an upregulation of anti-inflammatory cytokines (IL-10 and IL-4) and a downregulation of pro-inflammatory cytokines (TNF-a and IL-1β). The study showed that the use of RVG-modified exosomes derived BMMSC was better than exosomes derived BMMSC to improve cognitive function in APP/PS 1 mice. Conclusion: RVG-modified exosomes derived BMMSC can inhibit cell death by reducing Aβ and tau accumulation, balancing brain inflammatory factors, and improving memory and cognitive function. RVG-modified exosomes derived BMMSC has the potential as an advanced therapy for Alzheimer's disease and other neurogenerative diseases. Suggestion: Further research on the molecular mechanism, dosage, and side effects of RVG-modified exosomes derived BMMSC therapy in Alzheimer’s disease is needed.
