Ordering Information

Biological Activity

TCS PIM-1 1 is a potent and selective ATP-competitive inhibitor of Pim-1 kinase that displays marked selectivity over Pim-2 and MEK1/MEK2. By selectively inhibiting Pim-1 kinase activity, it blocks downstream phosphorylation of substrate proteins regulating cell cycle progression and cell survival. Inhibition of Pim-1 signaling suppresses oncogenic cellular proliferation and promotes apoptosis in target cancer cells, making it a valuable small-molecule tool for dissecting Pim kinase-mediated cellular pathways.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
