Verwenden
3,4-Dihydroxybenzoic Acid is a metabolite of polyphenols such as Phloretin (P339000) and Quercetin (Q509500).
Definition
ChEBI: A dihydroxybenzoic acid in which the hydroxy groups are located at positions 3 and 4.
Biosynthese
Protocatechuic acid is synthesized from the intermediates of the shikimate pathway. In this case, 3-dehydroshikimate is converted to protocatechuic acid as shown in Fig.11.2. Activity measurements from mung bean seedlings, on the other hand, indicate that 3-dehydroshikimate can be converted to protocatechuic acid (Widhalm and Dudareva 2015). Protocatechuic acid (11.12) upon hydroxylation produces gal- lic acid. The enzyme catalyzing this reaction is not well understood (Muir et al.2011).
Biosynthesis of Protocatechuic Acid
Allgemeine Beschreibung
Protocatechuic acid belongs to the class of polyphenolic compounds, which can be generally isolated from the dried flower of roselle. It can serve as a potential candidate possessing anticancer property, which can be involved in suppressing the growth of human promyelocytic leukemia HL-60 cells.
Biologische Aktivit?t
Protocatechuic acid (PCA) is a dihydroxybenzoic acid phenolic compound found in many edible and medicinal plants. It is a major metabolite of antioxidant polyphenols found in green tea and demonstrates free radical scavenging capability in a 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity assay (IC50 = 16.3 μM). It is thought to possess anti-inflammatory, antihyperglycemic, neuroprotective, and anticancer activities. Dietary administration of PCA dose dependently inhibits in vitro chemical carcinogenesis and exerts pro-apoptotic and anti-proliferative effects in different tissues. In studies of tumor cell migration and invasion using mouse melanoma B16/F10 cells, PCA at 0.1-2 mM down-regulated the Ras/Akt/NF-κB pathway by targeting RhoB activation, leading to a reduction of MMP-mediated activity.
