  4. GR 159897

GR 159897 is a highly potent, selective, competitive, brain-penetrated non-peptide neurokinin 2 (NK2) receptor antagonist. GR 159897 has little or no affinity for NK1 and NK3 receptors. GR 159897 inhibits binding of [3H]GR100679 to human NK2 (hNK2)-CHO cells and rat colon membranes with pKis of 9.51 and 10, respectively. Antagonizes bronchoconstriction. Anxiolytic-like and anti-tumor effects.

In Vitro

GR 159897 (10-30 μM; 72 hours; 4T1, 4THM, 4TLM and 67NR cells) treatment inhibits proliferation of cells in all cell lines dose- dependently, a response more pronounced in 4T1, 4THM and 4TLM cells compared to 67NR cells[2].
GR 159897 (10-30 μM; 72 hours; 4TBM, 4TLM, 4THM and 4T1 cells) treatment increases phosphorylation of P38, while inhibiting AKT activation in all metastatic cell lines whereas phosphorylation of ERK decreased in 4TBM, 4TLM and 4THM but not in 4T1 cells[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
