Lipophilicity presents a dual challenge in the realm of chemical drugs. The strong affinity between lipophilic compounds often results in highly potent substances in vitro being predominantly lipophilic. However, these potent compounds, owing to their heightened lipid solubility, frequently manifest undesirable traits like low solubility, rapid metabolism, and high plasma protein binding rates. These factors collectively contribute to diminished bioavailability and subpar pharmacological properties.
By conducting DMPK and PKPD studies, medicinal chemists would find out the problems and issues of lead compounds and shall be able to improve their drugability, if necessary, by modifying some “soft” and/or “hot” spots specifically, elevating the quality of drug candidates and lowering the risk of drug development. In this respect, 3D BioOptima can not only help clients to find out possible problems of drugability, but also to suggest possible approaches and solutions in solving the problems.
