8-Hydroxygenistein (8-OHG) is an antioxidant that can effectively scavenge nitric oxide (NO) and superoxide anion (O??). 8-Hydroxygenistein belongs to ortho-dihydroxy isoflavones (ODI) and is abundantly present in dark soy sauce and light soy sauce. Its antioxidant activity is stronger than that of its parent compound genistein. The content of 8-Hydroxygenistein is positively correlated with the antioxidant capacity of soy sauce (r = 0.959), and it remains highly stable even after being heated in boiling water for 60 minutes. During the brewing and storage of soy sauce, 8-Hydroxygenistein effectively prevents oxidative damage, making it promising for use in food antioxidant research.

Letaplimab (IBI-188) is a humanized IgG4 class antibody targeting CD47 and is often used in combination with azacitidine for the treatment of primary diagnosis of intermediate- to high-risk myelodysplastic syndromes.
