In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 2213-43-6, name is 1-Aminopiperidine, introducing its new discovery. HPLC of Formula: C5H12N2
A series of dihydrothienocyclopentapyrazole-based derivatives was synthesized and evaluated for the affinity at CB1 and CB2 receptors. The major term, the 6-methyl-1-(1,4-dichlorophenyl)-N-piperidinyl)-1,4- dihydrothieno[2?,3?-4,5]cyclopenta[1,2-c]pyrazole-3-carboxamide (6a), displayed a high affinity and good selectivity for CB2 receptors (Ki values of 2.30 nM for CB2 receptor and 440 nM for CB1 receptors respectively). Subsequent analogue preparation resulted in the identification of compounds such as 6b, 6d, 6e, 6k, 6l, 6m, 6s and 6t that showed 1.3-485 fold selectivity for CB2 receptors with potencies in the 1.1-7.2 nM range. These compounds profiled as full agonists at CB2 receptor in an inhibition assay of P-ERK 1/2 up regulation in HL-60 cells.
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 2213-43-6 is helpful to your research. HPLC of Formula: C5H12N2
