Abstract

The world is endangered by the COVID‐19 pandemic caused by SARS‐CoV‐2, people are dying in thousands every day, and without an actual treatment, it seems that bringing this global health problem to a quit is impossible. Natural products have been in constant use since ancient times and are proven by time to be effective. Medicinal plants from Indonesia may lead to the discovery of the novel drugs. Mangosteen or Garcinia mangostana L. is a native tropical fruit from Southeast Asia and is known to contain bioactive compounds. Interestingly, the main xanthone derivatives are alpha-mangostin and gamma-mangostin, these compounds have a variety of pharmacological activities such as antiviral activity. In summary, this study showed potential pharmacological benefits of alpha-mangostin and gamma-mangostin isolated from mangosteen against SARS-CoV-2. Thus, mangosteen exhibits as a valuable plant and a candidate for future drug development to fight SARS-CoV-2. However, further trials, such as in vitro and in vivo evaluation, are needed to prove the validity of these findings.

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a quickly spreading virus that posesa major burden on global human health. Thus, it is essential to develop COVID-19 vaccines. Vaccinedevelopment might not be easy, as a consequence of mutations. This study aimed to demonstrate the D614Gmutation in SARS-CoV-2 spike glycoprotein from Indonesia. 102 isolates from the GISAID EpiCoVdatabase and the Wuhan-Hu-1 isolate (reference sequence) from GenBank, NCBI were used in this study.BioEdit employed to examine the D614G mutation in the spike glycoprotein of SARS-CoV-2. In this report,there are 56 D614G mutations among 102 SARS-CoV-2 isolates. In summary, this report might suggestthat the D614G mutation implicates the COVID-19 pandemic in Indonesia. Nevertheless, this report was apreliminary study and this study recommends expanding molecular epidemiology and surveillance programsto monitor COVID-19

Abstract

Alpinia galanga (Zingiberaceae) or lengkuas is one type of herbal plant that is widely grown in SoutheastAsia. Various countries cultivate this medicinal plant, including Indonesia. This medicinal plant has a varietyof benefits and also be used as a treatment for many diseases. Although the lengkuas rhizome is the mostwidely used and studied part of the plant, the flower on the lengkuas can also provide additional advantages,such as antioxidant and antimicrobial properties. Therefore, this study aimed to demonstrate lengkuas for thefuture prospects against SARS-CoV-2. In summary, this study suggests that lengkuas might be useful as atreatment for COVID-19, although further studies could be conducted to confirm the results of computationalstudies.

Abstract

SARS-CoV-2, the causative agent of COVID-19, has led to more than two million deaths worldwide. Thereare currently no specific therapies approved to treat COVID-19 and drug repositioning, rather than newdrug discovery, which may be the best short-term option for controlling the pandemic. In this review, theauthor discusses important viral targets such as the papain-like protease, RNA-dependent RNA polymerase,3-chymotrypsin-like protease, and spike protein. The information about chemical compounds and targetsprovided in this review will aid further in vitro and in vivo studies to discover drugs to treat COVID-19.

This study was aimed to identify LethalConcentration 90% (LC90) of polar fraction extract from Citrus hystrix and Citrusaurantifolia leaves as biolarvicide against mosquito larvae after 24 hours of exposure.This study was an experimental research based on a Completely Randomized Design(CRD). The polar fraction extract of C. hystrix and C. aurantifolia were tested in concentrations of 0 ppm, 500 ppm, 1375 ppm, 2250 ppm, 3125 ppm, and 4000 ppm againstthe 3rd instar larvae of Culex quinquefasciatus. Each treatment was done in five independent replications. The numbers of deceased mosquito larvae were determinedafter 24 hours of treatment and analyzed by probit. The results showed that the polarfraction extract of C. hystrix and C. aurantifolia have bio-larvicidal activity against the 3rdinstar larvae of Cx. quinquefasciatus at LC90 of 1,653 ppm and 2,797 ppm, respectively. In conclusion, the polar fraction extract of C. hystrix leaf is more toxic than C. aurantifolialeaf's against Cx. quinquefasciatus larvae.

Abstract

Influenza virus infections are a major public health threat. Influenza viruses are associated with high mortality and morbidity worldwide through seasonal epidemics. Vaccination programs are available, but unpredictable antigenic changes in circulating strains require annual modification of seasonal influenza vaccines. Influenza vaccines are given, one of which is a trivalent influenza vaccine (TIV) aimed at the formation of antibodies that are specific to influenza viruses by B cells. In this study TIV vaccination has an effect in the form of decreasing viral replication in ferret that have been tested with H1N1 and H3N2 viruses. The results of this study are data about viral replication obtained from hemagglutination tests (HA test) and ATP6V0C expression with SDS-Page.

Abstract

Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a worldwide pandemic. Ginger (Zingiber officinale) is a rhizome, which is commonly used for culinary and medicinal purposes. In Indonesia, ginger is taken as traditional medicine by processing it into a drink known as jamu. The present study aimed to assess and evaluate the bioactive compounds in ginger that can be used in drug design for treating COVID-19. The crystal structure of the SARS-CoV-2 main protease (Mpro) was generated from a protein sequence database, i.e., Protein Data Bank, and the bioactive compounds in ginger were derived from the existing compounds library. Mpro is involved in polyprotein synthesis, including viral maturation and nonstructural protein gluing, making it a potential antiviral target. Furthermore, the bioactive compounds in ginger were analyzed using Lipinski’s rule of five to determine their drug-like molecular properties. Moreover, molecular docking analysis was conducted using the Python Prescription 0.8 (Virtual Screening Tool) software, and the interaction between SARS-CoV-2 Mpro and the bioactive compounds in ginger was extensively examined using the PyMOL software. Out all of the 16 bioactive compounds that were docked successfully, 4-gingerol, which has the lowest binding energy against SARS-CoV-2 Mpro, as per the virtual screening results, was proven to have the most potential as a viral inhibitor of SARS-CoV-2
