34707-92-1 Usage
Uses
Different sources of media describe the Uses of 34707-92-1 differently. You can refer to the following data:
1. The tetronic acid, chlorothricin, is an unusual macrocyclic antibiotic from a Streptomyces sp., related to kijanimicin, saccharocarcins, tetrocarcins and versipelostatin. Chlorothricin inhibits cholesterol biosynthesis from mevalonate, and inhibits pyruvate carboxylases purified from rat liver, chicken liver and Azotobacter vinelandii.
2. Chlorothricin is a spirotetronic acid antibiotic inhibitor of pyruvate carboxylase.
Biological Activity
chlorothricin is a macrolide-type antibiotic.macrolides, a class of natural products belonging to the polyketide class of natural products, consist of a large macrocyclic lactone ring. the lactone rings are oftem 14-, 15-, or 16-membered. some macrolides have been reported to have antibiotic or antifungal activity and are widely used as pharmaceutical drugs.
in vitro
in a previous study, chlorothricin was found to inhibit the reaction catalyzed by pyruvate carboxylase from bacillus stearothermophilus. moreover, with steady-state kinetic measurements, inhibition of the overall reaction was found to be competitive with the allosteric activator of this enzyme, coasac, and non-competitive with respect to both substrates of mgatp and pyruvate. these findings strongly indicated that the site 1conformation of pyruvate carboxylase responsible for the regulation of the overall enzyme activity could be influenced by chlorothricin and coasac in an antagonistic manner [1].
IC 50
173, 500, 260, and 120 μm for pyruvate carboxylases from bacillus, azotobacter, rat, and chicken, respectively.

Check Digit Verification of cas no
The CAS Registry Mumber 34707-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,0 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34707-92:
(7*3)+(6*4)+(5*7)+(4*0)+(3*7)+(2*9)+(1*2)=121
121 % 10 = 1
So 34707-92-1 is a valid CAS Registry Number.

Enantioselective total synthesis of (-)-chlorothricolide via the tandem inter- and intramolecular Diels-Alder reaction of a hexaenoate intermediate
Roush, William R.,Sciotti, Richard J.
, p. 7411 - 7419 (2007/10/03)
An enantioselective total synthesis of (-)-chlorothricolide (1) has been completed via a route involving the tandem inter- and intramolecular Dieis-Alder (IMDA) reaction of hexaenoate 19 and the chiral dienophile (R)-12. This reaction, which establishes s
