Biochem/physiol Actions
NMDA glutamatergic receptor agonist that is also an agonist at AMPA glutamatergic receptors at high concentrations.
Safety Profile
: Moderately toxic by
intraperitoneal, intravenous, and possibly
other routes. Mutation data reported. When
heated to decomposition it emits very toxic
fumes of NOx, SOx, and Cl-.
Purification Methods
Likely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
Check Digit Verification of cas no
The CAS Registry Mumber 52-89-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52-89:
(4*5)+(3*2)+(2*8)+(1*9)=51
51 % 10 = 1
So 52-89-1 is a valid CAS Registry Number.

A macrocylic dodecapeptide, cycloforskamide, was isolated from the sea slug Pleurobranchus forskalii, collected off Ishigaki Island, Japan. Its planar structure was deduced by extensive NMR analyses and was further confirmed by MS/MS fragmentation analyses. Finally, the absolute configuration was determined by total hydrolysis and chiral-phase gas chromatographic analysis. This novel dodecapeptide contains three d-amino acids and three thiazoline heterocycles and exhibits cytotoxicity against murine leukemia P388 cells, with an IC 50 of 5.8 μM.
