Khoom Taw Qhia
Protocatechualdehydeyog lub teeb daj siv lead ua. Lub melting point yog 153-154 degree . Nws yog soluble hauv dej kub thiab yooj yim soluble hauv ethanol thiab ether. Nws muaj ob pawg phenolic hydroxyl hauv nws cov qauv thiab muaj qee yam acidity. Nws tuaj yeem cuam tshuam nrog cov tshuaj alkaline los tsim cov ntsev sib xws. Txij li thaum nws muaj ob pawg phenolic hydroxyl, nws tuaj yeem koom nrog hauv kev hloov pauv nucleophilic, xws li reacting nrog halogenated hydrocarbons los tsim esters, ethers thiab lwm cov tebchaw. Tsis tas li ntawd, pawg aldehyde yog ib pab pawg ua haujlwm zoo heev uas tuaj yeem hloov tau yooj yim rau hauv pawg carboxyl, ester pawg, unsaturated ob daim ntawv cog lus, thiab lwm yam.

Khoom siv
Protocatechualdehydeyooj yim soluble nyob rau hauv ether. Ntawm 78 degree, 79g tuaj yeem yaj hauv 100ml ethanol. Ntawm 20 degree, 5g tuaj yeem yaj hauv 100ml dej. Ntawm 99 degree, 33g tuaj yeem yaj hauv 100ml dej. Nws yog me ntsis soluble hauv benzene thiab roj av ether. Melting point 153-154 degree (decomposition). Medium lethal dose (nas, intravenous) 56mg/kg. Kab mob. Siv: kev tshawb fawb biochemical. Organic synthesis, ib qho tseem ceeb ntawm cov tshuaj nruab nrab, tuaj yeem siv los tsim ntau yam tshuaj tua kab mob thiab tshuaj tiv thaiv kab mob.
Cov ntsiab lus ntawm protocatechuic aldehyde hauv Baike tshuaj pleev yog txiav txim los ntawm HPLC. Txoj kev: Diamonsil C{{0}}(18) kem (250mm × 4.6mm, 5μm) tau siv, thiab theem mobile yog methanol-dej tov uas muaj 0.5% acetic acid (21:79). Tus nqi ntws yog 1.5mL·min ~ (-1), thiab kev tshawb pom wavelength yog 281nm. Cov txiaj ntsig: Protocatechuic aldehyde muaj kev sib raug zoo ntawm kev sib raug zoo hauv thaj tsam ntawm 5. thiab RSD=1.75%. Xaus: Txoj kev no tuaj yeem siv los ua ib txoj hauv kev los tswj qhov zoo ntawm Baike ointment.
Protocatechualdehyde (50, 100 μM, 24 teev) kho MCF-7 hlwb nce 1.9-fold thiab 2.6-fold ntawm 50 μM thiab 100 μM concentrations, feem. . PCA inhibited qhov kev loj hlob ntawm cov tshuaj estrogen receptor (ER) zoo (MCF-7) cov qog nqaij hlav cancer mis, tab sis tsis yog ER tsis zoo (MDA-MB-231) cov qog nqaij hlav cancer mis. Protocechualdehyde (0, 100, 200 μM, 48 teev hauv HCT116 thiab SW480 hlwb) cuam tshuam rau kev ua haujlwm enzymatic ntawm HDAC, thiab kev kho PCA tau pom tias inhibit HDAC kev ua haujlwm nyob rau hauv koob tshuaj.
