Uses
HNMPA-(AM)3 is a cell-permeable and selective insulin receptor tyrosine kinase inhibitor analog of HNMPA. HNMPA-(AM)3 greatly inhibits the ability of prothoracicotropic hormone (PTTH) to activate ERK phosphorylation and stimulate ecdysteroidogenesis. HNMPA-(AM)3 is also effective in inhibiting ecdysteroid production (IC50=14.2 μM) and insulin receptor activity (IC50 is 14.2 μM and 200 μM in mosquitoes and mammals, respectively)[1][2].
Definition
ChEBI: Hydroxy-2-naphthalenyl-methyl phosphonic acid trisacetoxymethylester is an organic phosphonate that is the trisacetoxymethylester derivative of naphthalene substituted hydroxymethylphosphonic acid. It has been found to inhibit insulin receptor tyrosine kinase activity and insulin stimulated glucose oxidation. It has a role as a tyrosine kinase inhibitor. It is an organic phosphonate, a member of naphthalenes and an acetate ester. It is functionally related to a hydroxymethylphosphonic acid.
Biological Activity
Cell permeable: yes', 'Primary Target
tyrosine kinase', 'Product does not compete with ATP.', 'Reversible: no', 'Target IC50: 100 μM and 10 μM against insulin receptor tyrosine kinase and insulin-stimulated glucose oxidation in isolated r at adipocytes, respectively
