Performance of the natural compounds compared to the reference corticosteroid PLP is depicted in a colored profile. Cur has an inhibitory effect in all assays, whereas PN and PSS do not induce inhibition in any of the assays. PLP is ineffective to inhibit ROS production, whereas most NPs are very effective. (strong inhibition, green) Emax > 90%, low IC50, R2 > 0.70. (medium inhibition, yellow) Emax > 90%, medium IC50, R2 > 0.70 or Emax > 60%, low IC50, R2 > 0.70. (weak inhibition, orange) Emax > 30%, low IC50, R2 > 0.70. (no inhibition, red) Emax < 30%, R2 < 0.70. PLP = prednisolone disodium phosphate, EGCG = epigallocatechin gallate, BBCl = berberine chloride, Cur = curcumin, Apo = apocynin, Apo-e = apocynin ester, PN = paeonol, PTS = pterostilbene, PSS = pravastatin sodium.
