717920-85-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 717920-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,7,9,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 717920-85:
(8*7)+(7*1)+(6*7)+(5*9)+(4*2)+(3*0)+(2*8)+(1*5)=179
179 % 10 = 9
So 717920-85-9 is a valid CAS Registry Number.

Selective inhibition of Trypanosoma brucei 6-phosphogluconate dehydrogenase by high-energy intermediate and transition-state analogues

Dardonville, Christophe,Rinaldi, Eliana,Barrett, Michael P.,Brun, Reto,Gilbert, Ian H.,Hanau, Stefania

, p. 3427 - 3437 (2004)

Two series of compounds were designed to mimic the transition state and high-energy intermediates (HEI) of the enzymatic reaction of 6-phosphogluconate dehydrogenase (6PGDH). Sulfoxide analogues (7-11) were designed to mimic the transition state during the oxidation of the substrate to 3-keto-6-phosphogluconate, an enzyme-bound intermediate of the enzyme. Hydroxamate and amide derivatives of D-erythronic acid were designed to mimic the 1,2-cis-enediol HEI of the 6PGDH reaction. These two series of compounds were assayed as competitive inhibitors of the Trypanosoma brucei and sheep liver enzymes, and their selectivity value (ratio sheep/parasite) was calculated. The sulfoxide transition-state analogues showed weak and selective inhibition of the T. brucei enzyme. The hydroxamic derivatives showed potent and selective inhibition of the T. brucei 6PGDH with a Ki in the nanomolar range.
