Biological Activity

NCX 4040 is a nitric oxide-donating form of aspirin. NCX 4040 inhibits cyclooxygenase activity and releases NO, which can down-regulate COX2 expression and reduce the levels of superoxide accumulation. In the human monocytic cell line THP1, the compound inhibits PGE2 production and cytokine expression, and appears to stabilize IkB by inhibiting proteasome function. NCX 4040 has been shown to induce apoptosis in several tumor cell lines.

Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
