WebMar 15, 2024 · “A lower binding free energy means the drug can better compete against other molecules,” says Zhang, “meaning it can more effectively disrupt the protein’s normal function.” Calculating the binding … WebFor example, fluoroquinolone resistance by Mycobacterium tuberculosis can involve the production of a protein that resembles DNA. This protein is called MfpA (Mycobacterium fluoroquinolone resistance protein A). The mimicry of DNA by MfpA results in DNA gyrase binding to MfpA, preventing the binding of fluoroquinolones to DNA gyrase.

Only the unbound fraction of the drug undergoes metabolism in the liver and other tissues. As the drug dissociates from the protein, more and more drug undergoes metabolism. Changes in the levels of free drug change the volume of distribution because free drug may distribute into the tissues leading to a decrease in plasma concentration profile. For the drugs which rapidly undergo metabolism, clearance is dependent on the hepatic blood flow.

WebAug 3, 2024 · In plasma, drug molecules can reversibly interact with plasma proteins (mainly albumin, α1-acid glycoprotein (AAG), and, to a lesser extent, lipoproteins). Due to its size, the complex between the drug and a plasma protein cannot readily leave the intravascular space through transcellular diffusion across the endothelia. WebDrugs penetrate different tissues at different speeds, depending on the drug’s ability to cross membranes. For example, the antibiotic rifampin, a highly fat-soluble drug, rapidly enters the brain, but the antibiotic penicillin, a water-soluble drug, does not.
