and isomerically, Molecule 48:32 is 70% the mass of Nirmatrelvir. It has 80% the number of heavy atoms, and it has 60% the number of rotatable bonds than Nirmatrelvir. This molecule is much smaller and less flexible. It has 4 rings not 3, which makes it more compact in size. These parameters are seemingly better as far as tolerance and permittivity of it in the biological process of ingestion to the target protein.
