Description
N-Butylidenephthalide is a phthalide derivative useful for control of sensation disorder and olfaction disorder. It is a bioactive phthalide compound of Chuanxiong rhizoma, a Chinese herbal medicine used for treating headache obtained from the root of Ligusticum chuanxiong Hort. It has found that it can regulate tumor stem cell genes EZH2/AXL and reduced its migration and invasion in glioblastoma. Moreover, it can induce apoptosis in the A549 human lung adenocarcinoma cell line by coupled down-regulation of AP-2a and telomerase activity. Therefore, it is a potential cancer chemotherapy drug. Moreover, It can also exhibit protection against neurotoxicity through regulation of tryptophan 2, 3 dioxygenase in spinocerebellar ataxia type 3. Finally, it has certain antiplatelet effect.

Check Digit Verification of cas no
The CAS Registry Mumber 551-08-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 551-08:
(5*5)+(4*5)+(3*1)+(2*0)+(1*8)=56
56 % 10 = 6
So 551-08-6 is a valid CAS Registry Number.

Method used for preparing n-butylphathlide via one pot method
-
Paragraph 0023, (2017/01/19)
The invention belongs to the technical field of chemical synthesis, and more specifically relates to a method used for preparing n-butylphathlide via one pot method. The method comprises following steps: phthalic anhydride and valeric anhydride are subjected to a first step reaction under catalytic action of anhydrous sodium acetate, and generated n-pentanoic acid is collected via reduced pressure distillation; a sodium hydroxide solution of sodium borohydride is added into a reaction liquid for a second step of reaction; dichloromethane is used for extracting impurities; pH value is adjusted to be smaller than 7 with an acid for a third step of reaction, dichloromethane is used for extracting, and n-butylphathlide is obtained via concentration. The method is high in yield, low in cost, is safe, and is friendly to the environment.
