Descriptions:
3,4-Dihydroxybenzaldehyde, isolated from the outer skin of green ,has been shown to inhibit the growth of Gloeosporium musarum, a fungus which causes ripe fruit rot in the banana.[1]
3,4-Dihydroxybenzaldehyde can inhibit oxidative DNA damage and apoptosis via its antioxidant activity.[2]
3,4-Dihydroxybenzaldehyde inhibits the phosphotransferase activity of CKII with IC(50) of about 783 microM, it may function by inhibiting oncogenic disease, at least in part, through the inhibition of CKII activity.3]
3,4-Dihydroxybenzaldehyde inhibits the H2O2-induced apoptosis of granulosa cells, promotes estradiol secretion in granulosa cells and enhanced the mRNA expression levels of steroidogenic factor 1, a promoter of key steroidogenic enzymes. [4]
