Fluphenazine is a traditional antipsychotic compound that tightly binds the dopamine D2 receptor (Ki = 0.55 nM) and also reversibly inhibits calmodulin at micromolar concentrations. Fluphenazine-N-2-chloroethane is a derivative of fluphenazine that contains an alkylating chlorethylamine chain, which produces irreversible protein binding. It is a relatively selective, irreversible antagonist of D2 receptors both in vitro (IC50 = 100 nM) and in vivo, inactivating approximately 90% of D2 receptors in mice within 4 hours of treatment. Through this action, fluphenazine-B-2-chloroethane can be used to induce catalepsy in mice. It irreversibly inhibits calmodulin at higher doses (IC50 = 10 μM), which can sensitize cancer cells to TRAIL-induced apoptosis.
Autocamtide-2, amide is a highly selective peptide substrate for calcium calmodulin-dependent protein kinase II (CaMKII) assays (100 μM final concentration).
Autocamtide-2 is a highly selective peptide substrate for calcium/calmodulin-dependent protein kinase II (CaMKII), which belongs to the CAMK Ser/Thr protein kinase family.
Calmodulin antagonist-1 (W-7) is a calmodulin (CaM) antagonist that effectively inhibits calmodulin-activated Ca 2+ -phosphodiesterase (PDE) with an IC 50 of 28 μM. This compound also competitively inhibits trypsin-treated Ca 2+ -PDE with respect to cyclic GMP, exhibiting an IC 50 of 375 μM and a K i value of 300 μM.
Methyl orsellinate is a phytotoxic compound, it exhibits antifungal activity, it can cause significant inhibition of radicle growth of Amaranthus hypochondriacus and Echinochloa crus-galli, interact with bovine-brain calmodulin and inhibit the activation of the calmodulin-dependent enzyme cAMP phosphodiesterase. Methyl orsellinate can inhibit PTP1B activity with 50% inhibitory concentration values of 277 + - 8.6 microM, the selective inhibition of PTP1B has been widely recognized as a potential drug target for the treatment of type 2 diabetes and obesity, methyl orsellinate may can treat the type 2 diabetes and obesity.
