Possible Prevention of COVID 19 by Using Linoleic Acid (C18) Rich Algae Oil

With the rapid spread of COVID 19, people are being isolated in countries, and more than lakhs of people have been infecting by the coronavirus. The coronavirus is an airborne organism and highly infectious at short contact distances. The use of N95 respirators masks (high-efficiency) can protect people against the COVID 19, but the protective efficiency of masks is not high enough. A method of applying oil with rich amounts of linoleic acid in nostrils can prevent the spread of the virus. Macroalgal secondary metabolites have great potential for the development of new drugs and algae derived products largely employed in assorted industries, including agricultural, biomedical, food, and pharmaceutical industries. Among different chemical components isolated from algae, oil components are the most attracting more and which were subjected to a variety of studies (antiviral potential of algae in pharmaceutical research). Algal oil and their components like linoleic acid, oleic acid, palmitic acid, stearic acid are playing a preventive role in the virus infection. In addition, different mechanisms of action have been reported for these linoleic acid (C18H32O2) components, such as inhibiting the binding virus into the host cells or suppressing virulence activity by destabilization of the bilayer of viral envelopes. Application of in controlling the virus entry is mainly depend on the properties like low surface tension, high-boiling point, high viscosity, immiscible with water and antivirus activity. This manuscript mainly discusses the possible physical-chemical mechanisms involved in the application of algal oil and other sources of oils component's role in prevention of viral spread. Among that we listed out various oil sources and their applications in controlling the virus activity. Further confirmed experimental and clinical results for the use of oils as nasal spray may finally contribute to preventing the spread of the coronavirus as soon as possible
