Bispyrayafoline 

Bispyrayafoline is a pyrrolidone and antioxidant with an IC₅₀ value of 13.85 μM against DPPH. Bispyrayafoline can be found in the leaves of Murraya koenigii (Linn.) Spreng. Bispyrayafoline's antioxidant activity is concentration-dependent but time-independent. Bispyrayafoline can be utilized in studies concerning oxidative damage^[1][2].

Bispyrayafoline's (Compound 11) (1-100 μM; 0.5-24 h) free radical scavenging activity increases with increasing concentration, but is independent of time (100 μM)^[2].

Bispyrayafoline (30 min) exhibits an IC₅₀ of 13.85 μM against DPPH^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
