160582-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 160582-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,5,8 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 160582-66:
(8*1)+(7*6)+(6*0)+(5*5)+(4*8)+(3*2)+(2*6)+(1*6)=131
131 % 10 = 1
So 160582-66-1 is a valid CAS Registry Number.

Synthesis and QSAR of substituted 3-hydroxyanthranilic acid derivatives as inhibitors of 3-hydroxyanthranilic acid dioxygenase (3-HAO)

Linderberg, Mats,Hellberg, Sven,Bjoerk, Susanna,Gotthammar, Birgitta,Hoegberg, Thomas,Persson, Kerstin,Schwarcz, Robert,Luthman, Johan,Johansson, Rolf

, p. 729 - 744 (2007/10/03)

Novel 4,5-, 4,6-disubstituted and 4,5,6-trisubstituted 3- hydroxyanthranilic acid derivatives were synthesized and their ability to reduce the production of the excitotoxin quinolinic acid (QUIN) by inhibition of brain 3-hydroxyanthranilic acid dioxygenase (3-HAO) was subsequently investigated. The potency of the compounds to inhibit 3-HAO was assayed in rat brain homogenate, while chemical stability of certain compounds was studied by HPLC. The data were used to generate quantitative structure- activity relationship (QSAR) models for potency of 3-HAO inhibition and compound stability. Compounds with longer half-lives were obtained when the difference between the HOMO and LUMO was increased, while electron withdrawing groups in the 4- and 5-positions increased the potency of 3-HAO inhibition. Selected compounds that showed high potency in vitro were also found to be efficacious inhibitors in vivo after cerebral administration in rats.
