COVID-19 has become a global pandemic since 2020. The search for promising drugs based on the abundant herbal ingredients in Indonesia is one of the breakthroughs. Curcumin is a chemical compound with various potentials such as antioxidant, anti-inflammatory and antiviral. We conducted a molecular docking analysis to determine the potential of curcumin against SARS-CoV-2 non-structural and structural proteins, such as the main protease and spike protein. This study used the compound of curcumin (PubChem CID: 969516) from Curcuma longa L. or turmeric and two Indonesian SARS-CoV-2 isolates that have been deposited in the GISAID database (hCoV-19/Indonesia/JI-PNF-217315/2021 - EPI_ ISL_12777089 or lineage B.1.617.2 and hCoV-19/Indonesia/JI-PNF-211373/2021 - EPI_ISL_6425649 or lineage B.1.470). In addition, we used molnupiravir (PubChem CID: 145996610) as a drug control. We performed molecular docking analysis with PyRx software 0.9.9 (academic license) and visualization of molecular docking results with PyMOL software 2.5.4 (academic license). The results of this study found that curcumin had good potential against main protease and spike protein compared to the drug (control). In summary, we suggested that curcumin is a potential drug candidate against SARS-CoV-2. However, there is a need for future wet laboratory-based pre-clinical research such as in vitro and in vivo.

Objective: Covid 19 is a disease that infects cells in the airway lining the alveoli. This disease is caused by a virus named SarsCoV2. One way to handle it is to increase immunity. The body itself consists of immune system organs. One component of the immune system that is very important in protecting the body against the SARS-Cov-2 virus attack is Cluster of Differentiation 8+ T (CD8+T). CD8+T is one of the components of the adaptive immune system or often known as the specific immune system and is cytotoxic, so it is called Cluster of Differentiation8 +T. One of the plants used by the community to increase endurance is Sungkai (Peronema canescens Jack.). This study aims to see its activity against Cluster of Differentiation 8+ T (CD8+T). Methods: Sungkai leaf powder was extracted using 70\% ethanol solvent and evaporated using a rotary evaporator to obtain ethanol extract and fractionated with n-hexanes and isolated to obtain active isolates of sungkai leaves against the immune system. Isolates obtained from the isolation of the active fraction of n hexanes that have been tested as immunostimulants in previous studies. This study used test animals, namely male white mice of the wistar strain as many as 30 mice consisting of 5 heads for each group. Group I is a control group that is not given treatment and groups II, III, IV, V and VI are given exposure to the Sars CoV2 virus antigen that causes Covid 19 disease, namely using one of the Covid19 vaccines, namely the 0.0013 mL Moderna vaccine which is given Intra Muscular. Groups II, III, IV, V are treatment groups induced with Sars CoV2 antigen and given a test preparation, namely sungkai leaf isolate with 3 dose variations, namely 1, 10 and 100 mg/kg bw given orally, and group VI was given stimuno 50 mg/kgbw as a comparison. Results: From the results of immunostimulant testing of sungkai leaf isolate, it was found that stigmasterol has an immunostimulant effect in increasing Cluster of Differentiation 8 + T (CD8 + T) in the body given SARS-CoV-2 virus antigen. Significant results were seen in the 100 mg/kg bw dose group which increased CD8+T by 53.93 ng/dl. Based on statistical tests conducted in the form of ANOVA tests, CD8+T also showed significant differences with a significance value of \<0.05. Conclusion: Stigmasterol isolate of sungkai leaf has the effect of increasing Cluster of Differentiation 8+ T (CD8+T) levels in the body given exposure to SARS-CoV 2 virus antigens.

Coronavirus disease 2019 (COVID-19) is a new virus caused by SARS-CoV-2, a coronavirus from the coronavirus family, that can provoke severe respiratory syndrome. The disease became a pandemic in December 2019. Impaired immune modulation is one of the processes implicated in its pathogenesis, which contributes to poor COVID-19 outcomes. Many investigations have been conducted using medication to control coronaviral infections as antiviral agents or immunomodulators. The results of these tests, however, demonstrated that these medications were useless in fighting the disease. Some people believe that using herbal immunomodulators can aid in the prevention or even curing of COVID-19. Based on prior research, in the management of COVID-19, several botanicals may be useful. We go over the patient attitude and benefits of using such herbal remedies in the regimen of treating COVID-19 in Jordan.

The emergence of the novel β-coronavirus (SARS-CoV-2) and subsequent outbreak of COVID-19, is a global health challenge with no known treatment to date and has culminated in significant morbidity and mortality. This article highlights current understanding on SARSCoV- 2 based on the available scientific evidence on human coronavirus (HCoV) infections, which could offer novel insights and therapeutic targets for SARS-CoV-2, the causative agent of COVID-19. Specifically, the paper presents available phytotherapeutic evidence against pathogenic HCoVs with a view to identifying potent plant-derived antiviral agents that could be developed to aid the fight against coronaviruses and the current COVID-19. Evidently, elucidation of CoV integral proteins such as the spike protein, angiotensin-converting enzyme 2, 3C-like cysteine protease and papain-like protease, as good targets for drug developments has lent credence to the use of medicinal plants or their metabolites as prophylaxis or treatment interventions in CoV infections and holds promising ground for SARS-CoV-2. While some promising phytocompounds are currently under clinical trials for COVID-19, increased research into plants and in-depth characterization of their metabolites could reveal more interesting results that would benefit humanity in its fight against emerging and re-emerging viral infections including the current COVID-19. Overall, given the current body of evidence on the potential development of phytotherapeutics for COVID-19, fears need to be allayed while clinical trials continue. Conclusively, the lockdown and other preventive measures which have been implemented in most parts of the world should be humanely exercised and supported to ensure compliance and safety of lives.
