Txais tos muas 2-Chlorothiophene CAS 96-43-5 los ntawm peb. Txhua qhov kev thov los ntawm cov neeg siv khoom tau teb rau hauv 24 teev.Chlorothiophene; 2-Chlorothiophene, 97%; 2-Chlorothiphene; 2-Chlorothiophene; 2-Chlorothiophene, 98%; 2-Chlorothiophene, 98% 25ML; 2-CHLOROTHIOPHENE;
Txais tos muas 4-Aminobutyric acid CAS 56-12-2 los ntawm peb.γ-aminobutyric acid, lus Askiv lub npe: γ-aminobutyricacid (GABA) γ-aminobutyric acid, tshuaj lub npe: 4-aminobutyric acid; alias: γ-aminobutyric acid, aminobutyric acid, pipecolic acid, dav faib rau tsiaj thiab nroj tsuag hauv vivo. Cov noob, rhizomes thiab cov ntaub so ntswg ntawm cov nroj tsuag xws li taum, ginseng thiab suav tshuaj ntsuab muaj γ-aminobutyric acid. Hauv Chemicalbook tsiaj, GABA tsuas muaj nyob rau hauv cov paj hlwb nkaus xwb, thiab cov ntsiab lus hauv cov ntaub so ntswg ntawm lub hlwb yog li ntawm 0.1-0.6mg / g cov ntaub so ntswg. Kev tshawb fawb txog kev tiv thaiv kab mob tau pom tias qhov siab tshaj plaws ntawm GABA yog nyob rau hauv substantia nigra ntawm lub hlwb. Gamma-aminobutyric acid yog ib qho tseem ceeb inhibitory neurotransmitter uas tau kawm tob heev. Nws koom nrog ntau yam kev ua haujlwm metabolic thiab muaj kev ua haujlwm siab ntawm lub cev.
3,4-Dimethoxycinnamic acid CAS 2316-26-9; 6443-72-7 (O-Methylferulic acid) yog ib qho monomer rho tawm thiab purified los ntawm Securidaca inappendiculata. 3,4-Dimethoxycinnamic acid exerts anti-apoptotic nyhuv ntawm L-02 hlwb los ntawm ROS-mediated signaling txoj kev
