Description: |
Poseltinib is an orally active, selective, irreversible small-molecule Bruton tyrosine kinase (BTK) inhibitor with an IC50 of 1.95 nM and 0.3, 2.3, and 2.4 fold selective action against BMX, TEC, and TXK, respectively. Poseltinib covalently binds to the active site of BTK (cysteine 481 residue) and effectively inhibits B cell receptor (BCR), Fc receptor (FcR), and Toll-like receptor (TLR) mediated signaling. |
Stability and Solubility Advice: |
Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
