Isosakuranetin is a plant exudate with known cytotoxic and fungicide properties, it may act on wheat root segments as an inhibitor of K+ permeation. Isosakuranetin is a TRPM3 blocker, significantly reduces the sensitivity of mice to noxious heat and PregS-induced chemical pain; it induced- inhibition of ERK1/2 and PI3K/AKT signaling pathways activate MITF and subsequent expression of Tyr, TRP1, and TRP2. 4'-methoxy-5,7-dihydroxyflavanone is a dihydroxyflavanone that is flavanone substituted by hydroxy groups at positions 5 and 7 and a methoxy group at position 4' (the 2S stereoisomer). It has a role as a plant metabolite. It is a member of 4'-methoxyflavanones, a (2S)-flavan-4-one, a monomethoxyflavanone and a dihydroxyflavanone. It is functionally related to a (S)-naringenin.
