KN-92 phosphate_product_DataBase

Bioactivity	KN-92 phosphate is an inactive derivative of KN-93, without CaM kinase inhibitory activity. KN-92 phosphate is intended to be used as a control compound in studies designed to elucidate the antagonist activities of KN-93. KN-93 is a cell-permeable, reversible and competitive CaMKII inhibitor[1][2].
Invitro	KN-93 (5-50 μM; 24 hours) inhibits LX-2 cell growth and KN-92 (5-50μM; 24 hours) is ineffective in blocking cell growth[2].The analysis of cell cycle regulator expression reveals that KN-93 rather than KN-92 reduced the expression of p53 and p21[2]. Cell Viability Assay[2] Cell Line:
