Optical Activity UNSPECIFIED

KN-62 (1-[N,O-Bis(5-isoquinolinesulfonyl)-N-methyl-L-tyrosyl]-4-phenylpiperazine) is an inhibitor of Ca2+/calmodulin-dependent protein kinase II (Ca2+/CaM kinase II). In addition, it acts as an antagonist of the P2X7 receptor.

CNS Activity

Curator's Comment: Centrally administered KN-62 is CNS active in animals. No human data available.

In hepatoma cells 1-5 uM KN-62 substantially reduced HIF-1α levels in a dose-dependent manner. In contrast to hepatoma cells, MCF7 (breast cancer) and SK-N-MC (neuroblastoma) cells did not respond to KN-62, even at high concentrations, which suggests that HIF-1α suppression by KN-62 is cancer type-dependent.
