Biochem/physiol Actions

BOP (N-(Benzenesulfonyl)-L-prolyl-L-O-(1-pyrrolidinylcarbonyl)tyrosine sodium salt) is a potent and selective dual inhibitor of integrins alpha-4 beta-1 (α4β1) and alpha-9 beta-1 (α9β1) with Kd values in the picomolar range. BOP has been shown to preferentially mobilize hematopoietic stem cells (HSCs) and progenitors and to act synergistically with AMD3100.

Integrins alpha9beta1 and alpha4beta1 form a distinct structural class, but while alpha4beta1 has been subjected to extensive study, alpha9beta1 remains poorly characterized. We have used the small molecule N-(benzenesulfonyl)-(L)-prolyl-(L)-O-(1-pyrrolidinylcarbonyl)tyrosine (3) to investigate the biochemical properties of alpha9beta1 and directly compare

The inherent disadvantages of using granulocyte colony-stimulating factor (G-CSF) for hematopoietic stem cell (HSC) mobilization have driven efforts to identify alternate strategies based on single doses of small molecules. Here, we show targeting α9β1/α4β1 integrins with a single dose of
