Biochem/physiol Actions

Olsalazine is an anti-inflammatory drug used in inflammatory bowel disease and ulcerative colitis treatments. It is a pro-drug of 5-aminosalicylic acid (mesalamine) that it is converted by the bacteria in the colon to mesalamine. Olsalazine (5-aminosalicylic acid) is consider as a broad-spectrum anticancer agent. Additionally, olsalazine increases both eEF1A2 and utrophin A levels in in C2C12 myoblasts (relevant to Duchenne muscular dystrophy).

Improving the activity and selectivity profile of anticancer agents will require designing drug carrier systems that employ soluble macromolecules. Olsalazine-PAMAM-dendrimer-salicylic acid-conjugates with dendritic arms of different lengths have shown good stability regarding the chemical link between drug and spacer. In
