Application of 7651-81-2, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 7651-81-2, molcular formula is C9H7NO, introducing its new discovery.
Novel bicyclic piperazine derivatives of triazolotriazine and triazolopyrimidines as highly potent and selective adenosine A2A receptor antagonists
A series of bicyclic piperazine derivatives of triazolotriazine and triazolopyrimidines was synthesized. Some of these analogues show high affinity and excellent selectivity for adenosine A2a receptor versus the adenosine A1 receptor. Structure-activity-relationship (SAR) studies based on octahydropyrrolo[1,2-a]pyrazine and octahydropyrido[1,2-a]pyrazine with various capping groups are reported. Among these analogues, the most potent and selective A2a antagonist 26h has a Ki value of 0.2 nM and is 16 500-fold selective with respect to the A1 receptor. Among a number of compounds tested, compounds 21a and 21c exhibited significantly improved metabolic stability. Compounds 21a, 21c, and 18a showed good oral efficacy in rodent catalepsy models of Parkinson’s disease.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 7651-81-2 is helpful to your research. Application of 7651-81-2
