Syk/HDAC6-IN-1
Syk/HDAC6-IN-1 is a dual SYK/HDAC6 selective inhibitor with IC50 values of 0.19 nM (SYK) and 0.66 nM (HDAC6). Syk/HDAC6-IN-1 downregulates p-SYK to block downstream AKT/FOXO1 signaling, elevates acetylated histone H3 and α-tubulin via HDAC suppression, represses SREBF1 -mediated lipid biosynthetic pathways, triggers G0/G1 cell cycle arrest and robust mitochondrial-dependent caspase-3-mediated apoptosis in leukemia cells. Syk/HDAC6-IN-1 can be used for the research of FLT3-mutant acute myeloid leukemia.

Syk/HDAC6-IN-1 (Compound 14) exhibits significant SYK inhibitory activity with an IC50 of 0.19 nM[1].
Syk/HDAC6-IN-1 (48 h) suppresses proliferation of MV4-11 cells bearing FLT3-ITD mutations, with an IC50 of 0.11 μM[1].
Syk/HDAC6-IN-1 displays potent and preferential inhibitory activity toward HDAC6 with an IC50 of 0.66 nM, while it also inhibits HDAC1 (IC50=3.39 nM), HDAC2 (IC50=4.26 nM), and HDAC3 (IC50=7.55 nM) at low nanomolar concentrations[1].
Syk/HDAC6-IN-1 (0.5-2.5 μM; 24 h) effectively inhibits SYK activation and modulates HDAC inhibition-associated biomarkers in MV4-11 cells[1].
Syk/HDAC6-IN-1 binds tightly to the SYK pocket via extensive polar and nonpolar interactions[1].
Syk/HDAC6-IN-1 is highly selective for SYK, only weakly inhibiting FLT1, SLK, JAK2 and LCK among 60 tested kinases[1].
Syk/HDAC6-IN-1 occupies the catalytic tunnel of HDAC6 and establishes hydrogen bonds, hydrophobic contacts and catalytic zinc coordination[1].
Syk/HDAC6-IN-1 (0.25-1 μM; 24 h) fails to induce cell cycle arrest in MV4-11 cells, primarily driving apoptosis via mitochondrial membrane potential loss and caspase-3 cleavage while displaying moderate autophagy-inducing capacity[1].
Syk/HDAC6-IN-1 (0.5 μM; 48 h) effectively represses cholesterol and fatty acid metabolism at the transcriptomic level in MV4-11 cells[1].
Syk/HDAC6-IN-1 (0.25-1 μM; 24 h) dose-dependently reduces SREBF1 mRNA and inhibits lipogenic signaling in MV4-11 cells[1].
Syk/HDAC6-IN-1 (0.25-1 μM; 24 h) suppresses AKT activation, reduces FOXO1 phosphorylation and thereby activates FOXO1 in MV4-11 cells[1].
Syk/HDAC6-IN-1 (10-20 μM; 24 h) dose-dependently impairs endothelial tube formation and migration in HUVEC[1].
