118425-61-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118425-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,2 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118425-61:
(8*1)+(7*1)+(6*8)+(5*4)+(4*2)+(3*5)+(2*6)+(1*1)=119
119 % 10 = 9
So 118425-61-9 is a valid CAS Registry Number.

A new class of selective and potent 7-dehydrocholesterol reductase inhibitors

Horling, Aline,Müller, Christoph,Barthel, Richard,Bracher, Franz,Imming, Peter

supporting information, p. 7614 - 7622 (2012/11/07)

We prepared a number of N-phenethyltetrahydroisoquinolines structurally related to protoberberines. They were tested for activity against bacteria, fungi, and human leukemia HL-60 cells and also for inhibition of biosynthesis: ergosterol in yeasts and cholesterol in human cells. In the latter assay panel, several of the compounds were distinguished by a strong and selective inhibition of 7-dehydrocholesterol reductase (7-DHCR, EC 1.3.1.21), an enzyme responsible for the conversion of 7-dehydrocholesterol to cholesterol in the last step of cholesterol biosynthesis. In a whole-cell assay, the most active compound 5f showed a much stronger inhibition of overall cholesterol biosynthesis (IC 50 2.3 nM) than BM 15.766 (IC50 500 nM), presently the most selective known inhibitor of 7-DHCR. Since a defect of 7-dehydrocholesterol reductase is associated with Smith-Lemli-Opitz syndrome (SLOS), the potent and selective inhibitors reported here will enable more detailed investigation of the pathogenesis of SLOS.
