产品描述

PT 1 is a selective activator of AMPK with EC50 value of 0.3 μM for AMPK α1β1γ1 [1].

AMP-activated protein kinase (AMPK) is serine/threonine protein kinase that involved in cellular energy homeostasis and acts as an energy sensor. AMPK is a heterotrimer and increases ATP generation [1].

PT 1 is a selective AMPK activator. PT1 activated human AMPK α1394, AMPK α2398 and AMPK(α1β1γ1) with EC50 values of 8, 12 and 0.3 μM, respectively. PT1 exhibited maximum activity against AMPK(α1β1γ1) at concentration up to 5 μM. PT1 exhibited high selectivity for AMPK α catalytic subunit. PT1 activated truncated AMPK α1 subunit proteins including 313-335 aa with EC50 values of 8 μM, which was autoinhibitory domain. In HeLa cells without LKB1, PT1 induced AMPK and ACC phosphorylation, which were independent of LKB1. In human hepatoma HepG2 cells, PT1 dose-dependently reduced triacylglycerol and cholesterol content and induced AMPK and ACC phosphorylation [1]. In incubated mouse muscle, PT-1 increased γ1-containing AMPK activity and increased the AMPK-dependent phosphorylation of ULK1 on Ser555. However, in HEK293 cells expressing human γ1-, γ2- or γ3-AMPK, PT-1 activated them equally [2].
