Tolperisone (Figure Q15a) is a skeletal muscle relaxant. This drug is also known to bind to the active site of the SARS-CoV-2 main protease. Outline some hypothetically possible binding interactions that Tolperisone could make with this enzyme by matching amino acid sidechains (at the receptor surface) with four different parts of the drug's structure.
