Ibuprofen
Ibuprofen is a propionic acid-derived non-steroidal anti-inflammatory drug (NSAID), and is known to be the first propionic. Theformula of Ibuprofen is 2-(4-isobutylphenyl) propionic acid, originally discovered in 1960, while looking for a safer alternative of aspirin. Ibuprofen was eventually patented in 1961, and this drug was first introduced in the UK in 1969 and in the USA in 1974 against rheumatoid arthritis. It was the first NSAID available over the counter [36]. The ibuprofen is given as a racemic mixture on the available drugs. The R-enantiomer, undergoes comprehensive interconversion to the S-enantiomer in vivo through the action of racemase alpha-methylacyl-CoA, when its administered. It is commonly proposed; in particular, that the S-enantiomer is capable of generating greater pharmacological activity than the R-enantiomer [35], and its ability against 2019-nCoV is unclear and could be screened for further analysis.
