The type of side chain affects the anchoring ability of the ring peptide to the cell membrane. Stephanie M. Linker et al. Journal of Medicinal Chemistry 2023 66 (4), 2773-2788

How drugs enter the blood

  • One response
First, the molecule anchors itself to the surface of the membrane, before it penetrates the membrane in a direction perpendicular to it. In the next step, it changes its three-dimensional structure while passing through the membrane, rotating once along the longitudinal axis before reaching the opposite side of the membrane, where it exits the membrane again
