Synthesis and biological evaluations of novel bendazac lysine analogues as potent anticataract agents

Novel bendazac analogues and their salts have been designed and prepared. The resulting compounds (13c-d, 15c, 17c) showed very good aqueous solubility (>100 mg/mL). An in vitro assay showed that most of the resulting compounds had potent protective activity against the oxidative damage. Particularly, compound 13d was also able to enhance the WSP and T-AOC level in the H(2)O(2)/FeCl(3)-induced oxidative damage model, indicating the resulting compound may protect the lens through an antioxidant pathway.
