Mechanism of action
Although βCCE and other β-carbolines are not endogenous BZR
ligands (vide supra) and are not currently approved for clinical use, they are used to characterize different
GABAA/BZR subtypes (based on a and g subunit composition) and function (e.g., the partial agonist abecarnil)
toward the discovery of anxioselective drugs. In this regard, the β-carboline ring system is planar in comparison
to the boat conformation of the 1,4-benzodiazepines; thus, β-carbolines
have been useful to extend structure–activity relationship information for the agonist, antagonist, and inverse
agonist pharmacophores of the various GABAA/BZR subtypes.
Clinical Use
Several β-carbolines have approximately 10-fold higher affinity for the BZR when compared to diazepam. The ethyl
ester of β-carboline-3-carboxylic acid (βCCE), identified in human urine extracts as an artifact of the extraction
procedure, has very high affinity for the BZR.
Check Digit Verification of cas no
The CAS Registry Mumber 112037-78-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,0,3 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112037-78:
(8*1)+(7*1)+(6*2)+(5*0)+(4*3)+(3*7)+(2*7)+(1*8)=82
82 % 10 = 2
So 112037-78-2 is a valid CAS Registry Number.

The two-step synthesis of the title compound has been achieved by Mannich-type condensation of tryptamine with trifluoroacetaldehyde, followed by dehydrogenation with selenium dioxide; the overall yield was 79.3percent.
β-Carbolines as specific inhibitors of cyclin-dependent kinases

Harmine (3), 7-fluoro-1-methyl β-carboline (35) and 1-(5-methyl-imidazol-4-yl) β-carboline (41) were potent and specific inhibitors of cyclin-dependent kinases. The degree of aromaticity of the tricyclic ring and the positioning of substituents are important for inhibitory activity. While most β-carbolines inhibited CDK2 and CDK5 to the same extent, selective inhibition against CDK2 was observed in 1-(2-chlorophenyl)- (12), 1-(2-fluorophenyl)- (15), and 1-(2-chloro-5-nitrophenyl)- (28) β-carbolines.
