The Naproxcinod, with the CAS registry number 163133-43-5, is also known as (S)-2-(6-Methoxy-2-naphthyl)propanoic acid 4-nitrooxybutyl ester. It belongs to the classification codes of Cardiovascular Agents; Nitric Oxide Donors; Osteoarthritis. This chemical's molecular formula is C₁₈H₂₁NO₆ and molecular weight is 347.36. What's more, both its IUPAC name and systematic name are the same which is called 4-Nitrooxybutyl (2S)-2-(6-methoxynaphthalen-2-yl)propanoate. Naproxcinod is a non-steroidal anti-inflammatory drug. It is a derivative of naproxen with a nitroxybutyl ester to allow it to also act as a nitric oxide donor. This second mechanism of action makes naproxcinod the first in a new class of drugs, the cyclooxygenase inhibiting nitric oxide donators, that are hoped to produce similar analgesic efficacy to traditional NSAIDs, but with less gastrointestinal and cardiovascular side effects.
