Background: Coronavirus disease 2019 (COVID-19) has been recently declared as a global public health emergency, where the infection is caused by SARS-CoV-2. Nowadays, there is no specific treatment to cure this infection. The main protease (Mpro) of SARS-CoV-2 and SARS spike glycoprotein- human ACE2 complex have been recognized as suitable targets for treatment, including COVID-19 vaccines. Objective:: In our current study, we identified the potential of Momordica charantia as a prospective alternative and a choice in dietary food during a pandemic. Materials and Methods: A total of 16 bioactive compounds of Momordica charantia were screened for activity against 6LU7 and 6CS2 with AutoDockVina. Results: We found that momordicoside B showed the lowest binding energy compared to other compounds. In addition, kuguaglycoside A and cucurbitadienol showed better profiles for drug-like properties based on Lipinski's rule of five. Conclusion: Our result indicates that these molecules can be further explored as promising candidates against SARS-CoV-2 or Momordica charantia can be used as one of the best food alternatives to be consumed during the pandemic.

Introduction: Paederia foetida and Vitis vinifera were reported to have antioxidant activities due to their polyphenolic phytochemical contents. Arbutin may be included as active compounds in the plants. The chemometric analysis is used to identify the similarity of functional groups found in arbutin and that are in Paederia foetida and Vitis vinifera. Materials and Method: The ethanol extracts of Paderia foetida and Vitis vinifera were subjected to compound partition and characterization. Then a liquid-liquid partition is carried out using n-hexan and water solvents, followed by ethyl acetate and water partitions. This procedure is carried out continuously until the top layer is cleared. Partitioned compounds were analyzed using FTIR spectroscopy to identify functional groups. Furthermore, it was analyzed using the chemometric method (Principal Component Analysis and Cluster Analysis). Results: From the results of FTIR spectroscopy, functional groups in Paederia foetida and Vitis vinifera were identical to functional groups found in arbutin. PCA Analysis was achieved using principal component accounting an eigenvelue about 99,3 % of the total variance. Conclusions: CA analysis showed that compounds in Paederia foetida (Euclidean distance 0.537) and Vitis Vinifera (Euclidean distance 1.157) may be similar with arbutin.
