Aliskiren is a hydrophilic molecule. When bound to renin, aliskiren occupies the S1, S1', S2', and S3 hydrophobic regions of renin. Most importantly aliskiren occupies the S3<sup>SP</sup> region that is equally hydrophobic and hydrophilic and greatly increases binding affinity.<ref>PMID: 20731374</ref> Aliskiren interacts with multiple residues in renin. | Aliskiren is a hydrophilic molecule.

There are three generations of renin inhibitors. The first two generation molecules were peptide molecules. These peptide molecules were not specific or effective as renin inhibitors. Aliskiren, part of the 3<sup>rd</sup> generation, is a nonpeptide renin inhibitor. Small molecule nonpeptide inhibitors such as aliskiren have good pharmokenetics and are very specific for renin and not other protein peptidases. Advancements in crystallography and molecular modeling allowed the discovery of aliskiren. Aliskiren inhibits renin activity. Since renin is the rate limiting step of the RAS renin inhibition is a successful method to lower blood pressure. | There are three generations of renin inhibitors.
