24563-03-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24563-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,6 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24563-03:
(7*2)+(6*4)+(5*5)+(4*6)+(3*3)+(2*0)+(1*3)=99
99 % 10 = 9
So 24563-03-9 is a valid CAS Registry Number.

Two glycosides from the stem bark of Tetracentron sinense

Yi, Jin-Hai,Zhang, Guo-Lin,Li, Bo-Gang,Chen, Yao-Zu

, p. 1001 - 1003 (2000)

Two glycosides, tetracentronsides A and B, were isolated from the stem bark of Tetracentron sinense Oliv., along with ten known compounds, β- sitosterol, lupeol, betulinic acid, oleanolic acid, vanillic aldehyde, vanillic acid, maslinic acid, huazhongilexin, daucosterol and catechin. On the basis of spectral and chemical evidence, tetracentronside A and B were identified as 3,4,5-trimethoxyphenyl-O-6'-O-vanilloyl-β-D-glucopyranoside and (8R, 8'R) 9-β-D-glucopyranosyl dihydrocubebin, respectively.

Lignans from the fruit of Schisandra glaucescens with antioxidant and neuroprotective properties

Yu, Heng-Yi,Chen, Zu-Yu,Sun, Bin,Liu, Junjun,Meng, Fan-Yu,Liu, Ye,Tian, Tian,Jin, An,Ruan, Han-Li

, p. 1311 - 1320 (2014)

Two rare 7,8-seco-lignans (1, 2), three new lignan glycosides (3, 4a, 4b), and 10 known lignans (5-14) were isolated from the fruit of Schisandra glaucescens Diels. The absolute configurations of 1 and 2 were determined by comparing their experimental and calculated electronic circular dichroism spectra. The molecular structures of the new compounds (3, 4a, and 4b), including their absolute configurations, were determined using various spectroscopic methods and hydrolysis reactions. The antioxidant activities of the isolated compounds were tested using 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays. Compounds 4, 7, 8, 10, 11, and 12 exhibited antioxidant activities of varying potential in both assays. Of these compounds, 7 showed the strongest 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, with IC50 values of 15.7 (150 μM DPPH) and 34.6 μM (300 μM DPPH), respectively, and 4, 12, and 7 displayed higher total antioxidant activities than Trolox in the ferric reducing antioxidant power assay. The neuroprotective effects of these compounds against Aβ25-35-induced cell death in SH-SY5Y cells were also investigated. Compounds 1, 2, 6, 7, 8, 11, and 12 exhibited statistically significant neuroprotective effects against Aβ25-35-induced SH-SY5Y cell death compared with the group treated only with Aβ25-35.

Pinoresinol-lariciresinol reductase: Substrate versatility, enantiospecificity, and kinetic properties

Davin, Laurence B.,Hwang, Julianne K.,Lewis, Norman G.,Moinuddin, Syed G. A.

, (2020/03/26)

Two western red cedar pinoresinol-lariciresinol reductase (PLR) homologues were studied to determine their enantioselective, substrate versatility, and kinetic properties. PLRs are downstream of dirigent protein engendered, coniferyl alcohol derived, stereoselective coupling to afford entry into the 8- and 8′-linked furofuran lignan, pinoresinol. Our investigations showed that each PLR homolog can enantiospecifically metabolize different furofuran lignans with modified aromatic ring substituents, but where phenolic groups at both C4/C4′ are essential for catalysis. These results are consistent with quinone methide intermediate formation in the PLR active site. Site-directed mutagenesis and kinetic measurements provided additional insight into factors affecting enantioselectivity and kinetic properties. From these data, PLRs can be envisaged to allow for the biotechnological potential of generation of various lignan skeleta, that could be differentially “decorated” on their aromatic ring substituents, via the action of upstream dirigent proteins.
