Research output: Contribution to journalArticle

Synthesis and bioactivity of novel dual acting nitric oxide releasing and reactive oxygen scavenging hybrid compound SA-2 is described. The hybrid molecule SA-2 significantly increased the superoxide dismutase enzyme level and protected the photoreceptor cells from H2O2 induced oxidative stress. Synthesis of ocular esterase sensitive aceloxy alkyl carbamate prodrug SA-4 with improved aqueous half-life is achieved to aid topical ocular formulation. This class of hybrid molecule and prodrug may have dual potential of improved IOP lowering and neuroprotection in glaucomatous optic neuropathy.
