Background

Nitroaspirin (NCX 4016) is a nitric oxide (NO) donor and a nitro-derivative of Aspirin, which combines with Nitroaspirin to inhibit cyclooxygenase. Nitroaspirin (NCX 4016) has antithrombotic and anti-platelet properties and acts as a direct and irreversible inhibitor of COX-1. Nitroaspirin (NCX 4016) causes significant induction of cell cycle arrest and apoptosis in Cisplatin-resistant human ovarian cancer cells via down-regulation of EGFR/PI3K/STAT3 signaling and modulation of Bcl-2 family proteins[1][2][3][4].
