BAY 61-3606
Based on 12 publication(s) in Google Scholar
BAY 61-3606 is an orally available, ATP-competitive, reversible and highly selective Syk inhibitor with a Ki of 7.5 nM and an IC50 of 10 nM. BAY 61-3606 reduces ERK1/2 and Akt phosphorylation in neuroblastoma cell. BAY 61-3606 induces a large decrease of Syk phosphorylation in K-rn cell lysates. Bay 61-3606 sensitizes TRAIL-induced apoptosis by downregulating Mcl-1 in breast cancer cells.

BAY 61-3606 (0.01-10 μM ; 48 hours) significantly reduces the cell viability of SYK-positive SH-SY5Y and SYK-negative SK-N-BE cells in a dose-dependent matter. SH-SY5Y cells expressing high SYK levels are significantly more sensitive to BAY 61-3606 in comparison to SK-N-BEcells expressing very low or no SYK[2].
BAY 61-3606 (0.4 and 0.8 μM; 4 or 24 hours) inhibits SYK activity by reducing ERK1/2 and Akt phosphorylation in neuroblastoma cell SH-SY5Y[2].
BAY 61-3606 (2 μM; 2 hours) induces a large decrease of Syk phosphorylation in K-rn cell lysates[3].
