Drug uptake
WebDrug release is achieved by two sets of mechanisms: photochemical changes and photothermal changes. Photochemical changes include the following: 1. Dynamic photooxidation, for example, by octabutoxy phthalocyanine, etc., and production of reactive oxygen species causing membrane disruptions and prodrug activation. 2.

Reduced drug uptake is the third major mechanism responsible for β-lactam resistance in gram-negative bacteria, where β-lactams need to enter the periplasmic space to bind the PBP targets located in the cytoplasmic membrane. In fact, in gram-negative bacteria, the activity of β-lactams against the bacterial cell depends on the complex ...
