Synthesis, structure, urease inhibitory, and cytotoxic activities of two complexes with protocatechuic acid derivative and phenanthroline.

Protocatechuic acid (PCA), as 3, 4-dihydroxybenzoic acid, is a water-soluble monomeric phenolic acid and widely distributed in many traditional Chinese herbal medicines. It is a conjugate acid of a 3,4-dihydroxybenzoate.

Sigma-Aldrich offers a number of Protocatechuic acid products. Epichlorohydrin, benzyltriethylammonium chloride and 4,4′-methylenedianiline (DDM), Sodium hydroxide were purchased from Adamas Company, China.

All solvents were utilized as received. Flavonoids and polyphenols are heterocyclic molecules that have been associated with beneficial effects on human health, such as reducing the risk of various diseases like cancer, diabetes, and cardiovascular and brain diseases. Protocatechuic acid was provided by Tianjin institute of industrial biotechnology, Chinese Academy of Sciences. For each heterologous reaction step, we analyzed several potential candidates for their expression and activity in yeast to compose a functional cis,cis-muconic acid synthesis pathway. Protocatechuic acid (PCA) is a type of widely distributed naturally occurring phenolic acid. 2.2. It derives from a benzoic acid. The pathway consists of three heterologous microbial enzymes, 3-dehydroshikimate dehydratase, protocatechuic acid decarboxylase composed of three different subunits, and catechol 1,2-dioxygenase. Protocatechuic acid (3, 4-dihydroxybenzoic acid) is a natural phenolic compound found in many edible and medicinal plants.
