Role of Pineapple and its Bioactive Compound Bromelain in COVID 19

Background:: Ananas comosus (L.) Merr., which is commonly known as pineapple, is a well-studied plant for its medicinal properties. In terms of commercial importance, it ranks third among tropical fruits. It has been used for its antidiabetic, antimalarial, anticancer, abortifacient, antioxidant, and antidiarrhoeal activities. The review aimed to study the effects of pineapples and their bioactive compounds on the SARS-CoV-2 virus. Methods:: Research methods comprise significant studies on the treatment of COVID-19 utilizing pineapple and its bioactive compounds. To carry out the e-literature review, articles were downloaded from online search engines, including Elsevier, PubMed, and Google Scholar, using pineapple, bioactive compounds, bromelain, clinical trial, and COVID-19. Results:: The literature showed that pineapple and its bioactive compounds showed antiviral effects in COVID-19 patients by inhibiting the proinflammatory cytokines and affecting various signaling molecules, including NF-κB, proinflammatory cytokines, and cyclooxygenase-2. They modulate apoptotic protein levels and also cause a reduction of ACE-2 and TMPRSS2 expression. Conclusion:: For the development of phytomedicine that adheres to all safety regulations, pineapple, and its bioactive compounds can serve as lead molecules for clinical studies in SARS-CoV-2 infection treatment and therapy.
