[CAS NO. 425637-18-9]  Sotrastaurin (AEB071)

Sotrastaurin (< 10μM) treatment effectively abrogated at low nanomolar concentration markers of early T-cell activation, such as interleukin-2 secretion and CD25 expression, in primary human and mouse T cells. Sotrastaurin (200 nM) inhibits the CD3/CD28 antibody- and alloantigen-induced T-cell proliferation responses in the absence of nonspecific antiproliferative effects. Sotrastaurin (<3 μM) markedly inhibits lymphocyte function-associated antigen-1-mediated T-cell adhesion. Sotrastaurin(< 20 μM) selectively impair the proliferation of CD79 mutant ABC DLBCL cell lines, correlating with decreased NF-κB signaling avctivity. AEB071 at concentration of 5 μM induces G1 arrest and/or cell death in CD79 mutant cells.
