Chemical Properties

White Solid

Check Digit Verification of cas no

The CAS Registry Mumber 91364-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,6 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91364-12:
124 % 10 = 4
So 91364-12-4 is a valid CAS Registry Number.

The title compounds and the corresponding L-gulo derivatives were synthesised in 6 steps from benzyl 2,3:5,6-di-O-isopropylidene-α-D-mannofuranoside.The Ki values, determined from inhibition studies with α-D-mannosidases from jack beans, almonds, and calf liver, and β-D-mannosidase from Aspergillus wentii, ranged from 70 to 400 μM for the mannitol derivative and from 1.2 to 20 μM for 5-amino-5-deoxy-D-mannopyranose, i.e., inhibition is E2-E4-fold stronger than with D-mannose.Marked enhancement of inhibition with increasing pH is ascribed to the ionisation of a carboxyl group at the active site, forming an ion pair with the protonated inhibitor.The inhibition equilibrium between the jack-bean enzyme and the mannose derivative was approached slowly with kapp 2.0E5 M-1.min-1.The mannose-derived inhibitor was also inhibitory against β-D-glucosidases from almonds and Asp. wentii, with Ki values only 20-150-times larger than those for the inhibition of these enzymes by 5-amino-5-deoxy-D-glucopyranose.This moderate discrimination in binding of D-gluco and D-manno derivatives is in marked contrast to the high specificity shown by the glucosidase in catalysing the hydrolysis of mannosidases.A similar low specificity with respect to binding, combined with highly specific catalysis, was also seen with the mannosidases acting on inhibitors and substrates with the D-gluco configuration.
