81771-19-9 Usage
Uses
Used in Agricultural Industry:
Lolitrem B is used as a natural defense mechanism for [application reason] in the agricultural industry. The presence of Lolitrem B in perennial ryegrass helps protect the grass from being overgrazed by animals, as the neurotoxin causes ryegrass staggers, deterring animals from consuming the infected grass.
Used in Research and Development:
Lolitrem B is used as a subject of ongoing research for [application reason] in the fields of chemistry, biology, and toxicology. Its complex structure and potent neurotoxin properties make it an interesting compound for studying the effects of natural toxins on animals and exploring potential applications in pest control or other areas. Additionally, research into the synthesis and analysis of Lolitrem B can contribute to the development of new methods for producing and studying complex chemical compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 81771-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,7 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81771-19:
(7*8)+(6*1)+(5*7)+(4*7)+(3*1)+(2*1)+(1*9)=139
139 % 10 = 9
So 81771-19-9 is a valid CAS Registry Number.

A new lolitrem, lolitrem F (2), was isolated from endophyte-infected perennial ryegrass. Its structure was shown by mass spectrometry and one- and two-dimensional NMR spectroscopy to be a 31,35-cis-fused isomer of lolitrem B. Base-catalyzed epimerization of 2 and lolitrem B (1) afforded their 31-epimers (4 and 3, respectively). Comparison with spectral data for 1 and 31-epi-lolitrem B (3) established lolitrem F to be 35-epi-lolitrem B. Compounds 1, 2, and 4 were equally tremorgenic in a mouse bioassay, but 3 was nontremorgenic. Base-catalyzed exchange of H-31 was found to permit efficient incorporation of deuterium (and potentially, therefore, of tritium) into 1 and 3.
