This creates a dual mechanism of action
Carnosine Carnosine scavenges these reactive carbonyl species and free radicals
When the intact complex reaches fibroblasts or keratinocytes, key documented mechanisms include: Collagen and GAG synthesis: In vitro studies show GHK-Cu upregulates procollagen type I and III synthesis and stimulates decorin and glycosaminoglycan production in human fibroblast cultures
2) Acid-sensitive cleavable linkers: Mylotarg, Besponsa, Trodelvy The acid-sensitive strategy is to use a lower pH of the endosome (pH = 5-6) and lysosome (pH = 4.8) compartments compared to the cytoplasm (pH = 7.4) to trigger the hydrolysis of an acid-labile group within the linker, such as a hydrazone
To calculate absolute (i.e., water-referenced) GSH levels from GSH/Cr ratios, concentrations of total Cr (Cr plus phosphocreatine) were calculated
