N-methyl Paroxetine is a derivative of the selective serotonin reuptake inhibitor (SSRI) antidepressant paroxetine that inhibits [3H]paroxetine binding to rat cortical membranes (Ki = 4.3 nM). It inhibits serotonin uptake in rat brain synaptosomes with an IC50 value of 22 nM. N-methyl Paroxetine has been used as a precursor in the synthesis of paroxetine and is a potential impurity in commercial preparations of paroxetine.
Paroxetine Mesylate, the mesylate salt form of paroxetine, is a phenylpiperidine derivative and a selective serotonin reuptake inhibitor (SSRI) with anxiolytic and antidepressant properties.
GRKs-IN-1 hydrochloride, Compound 14as, has remarkable potency against and selectivity for G protein-coupled receptor kinase 2 GRK2 (IC50=130 nM) and GRK5 (IC50=7.1 μM).GRKs-IN-1 hydrochloride is a derivative 14as of paroxetine, shows a 100-fold improvement in cardiomyocyte contractility assays over paroxetine[1].
