Description : PCI-32765, also named as Ibrutinib, is a Bruton tyrosine kinase inhibitor which is used to study the biological effects of Bruton tyrosine kinase inhibition on mature B-cell function and the progression of B cell-associated diseases in vivo. The Bruton tyrosine kinase is specifically necessary for BCR signaling as demonstrated by human and mouse mutations that disrupt Bruton tyrosine kinase function and prevent B-cell maturation at steps which need a functional BCR pathway. PCI-32765 also inhibited autoantibody production. Occupancy of the Bruton tyrosine kinase active site by PCI-32765 was monitored in vitro and in vivo using a fluorescent affinity probe for Bruton tyrosine kinase.
