WebbPlasma stability plays an essential role in drug discovery and development. In addition to hepatic metabolism, compounds will also be subject to degradation and modification by enzymes in plasma, particularly hydrolases and esterases. Unstable compounds tend to have rapid clearance and short half-life, which leads to poor in vivo performance. WebbThe major plasma proteins that can interact with drugs are: Albumin Alpha-1-acid glycoprotein Lipoproteins In general, acidic and neutral drugs primarily bind to albumin, and basic drugs bind to the acidic alpha-1 acid glycoprotein or Lipoproteins Albumin (MWt 66 KDa), (HSA) is the most abundant protein in human blood plasma at 3.5 to 5.0 g/dl.
