19536-25-5 Usage
Description
2-O-Acetyl-20-hydroxyecdysone is an ecdysone steroid hormone that has been found in plants and animals. It completely inhibits the growth of the bacteria S. aureus, E. coli, and P. vulgaris, as well as the fungi C. albicans, A. alternata, and F. solani when used at a concentration of 10 μg/ml. 2-O-Acetyl-20-hydroxyecdysone (50 μM) increases aggregation of amyloid-β (1-42) (Aβ42), increases fibril formation by 60%, and decreases oligomer levels in cell-free assays. It reduces Aβ42-induced cytotoxicity of SH-SY5Y cells when used at concentrations of 5 and 10 μM.
Check Digit Verification of cas no
The CAS Registry Mumber 19536-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,5,3 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19536-25:
(7*1)+(6*9)+(5*5)+(4*3)+(3*6)+(2*2)+(1*5)=125
125 % 10 = 5
So 19536-25-5 is a valid CAS Registry Number.

, p. 143 - 147 (2007/10/02)
From the crude drug Chorei, the fruit body of Polyporus umbellatus, seven new components named polyporusterone A. B, C, D, E, F and G, were isolated and their structures were determined on the basis of the spectral data. These compounds showed cytotoxic action on leukemia 1210 cell proliferation.
