|Biological Activity or Inhibitors:||1. 4-Hydroxybenzaldehyde shows an inhibitory effect on the GABA transaminase to contribute to an antiepileptic and anticonvulsive activity, and its inhibitory activity was higher than that of valproic acid, a known anticonvulsant.
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Functional and structural characterization of an unusual cofactor-independent oxygenase.[Pubmed: 25565350]|
|The vast majority of characterized oxygenases use bound cofactors to activate molecular oxygen to carry out oxidation chemistry. Here, we show that an enzyme of unknown activity, RhCC from Rhodococcus jostii RHA1, functions as an oxygenase, using 4-hydroxyphenylenolpyruvate as a substrate. This unique and complex reaction yields 3-hydroxy-3-(4-hydroxyphenyl)-pyruvate, 4-Hydroxybenzaldehyde, and oxalic acid as major products.|

|Chemical constituents from safflower injection and their bioactivity.[Pubmed: 25509295]|
|The chemical constituents of Safflower injection were isolated and purified by polyamide, silica gel, Sephadex LH-20, ODS column chromatographies and preparative HPLC. As a result, sixteen compounds have been isolated. Based on the spectral data analysis, their structures were elucidated as scutellarin (1), kaempferol-3-O-β-rutinoside(2), hydroxysafflor yellow A(3), rutin (4), coumalic acid(5), adenosine(6), syringoside(7), (3E)-4-(4'-hydroxyphenyl)-3-buten-2-one(8), (8Z)-decaene-4, 6-diyne-1-Oβ-D-glucopyranoside(9), 4-Hydroxybenzaldehyde (10), (2E, 8E) -tetradecadiene-4, 6-diyne-1, 12, 14-triol-1-O-β-D-glucopyranoside (11), kaem-pferol-3-O-β-sophorose (12), uridine (13), roseoside (14), cinnamic acid (15), and kaempferol (16).|

|Inhibition of GABA shunt enzymes' activity by 4-hydroxybenzaldehyde derivatives.[Pubmed: 16290145]|
|4-Hydroxybenzaldehyde (HBA) derivatives were examined as inhibitors for GABA transaminase (GABA-T) and succinic semialdehyde dehydrogenase (SSADH). Investigation of structure-activity relation revealed that a carbonyl group or an amino group as well as a hydroxy group at the para position of the benzene ring are important for both enzymes' inhibition. HBA was shown to give competitive inhibition of GABA-T with respect to alpha-ketoglutarate and competitive inhibition of SSADH. 4-Hydroxybenzylamine (HBM) also showed the competitive inhibition on GABA-T with respect to GABA.|
