What are the pharmacokinetic properties of the rivastigmine hybrids, and how do they compare to rivastigmine?

Label:chem

Topic
The pharmacokinetic properties of a drug, such as its ability to cross the blood-brain barrier (BBB) and its oral bioavailability, are crucial for its therapeutic efficacy.
Answer
The rivastigmine hybrids generally exhibited higher polar surface area (PSA) and lipophilicity (clog Po/w) compared to rivastigmine. These properties are important for drug permeability and bioavailability. The predicted log BB values for the hybrids were lower than those for rivastigmine, indicating potentially reduced BBB permeability. However, the Caco-2 and MDCK permeability values varied, with some hybrids showing higher permeability than rivastigmine. None of the compounds violated Lipinski's Rule of Five, suggesting they have good potential for oral bioavailability.
