YDH-704
YDH-704 is a PAK1/HDAC10 inhibitor, with IC50 values of 0.05 μM and 0.02 μM against human targets, respectively. YDH-704 blocks PAK1-mediated oncogenic signaling pathways, inhibits the proliferation and migration of tumor cells, suppresses the epigenetic regulatory function of HDAC10, downregulates PD-L1 expression, and regulates polyamine metabolism. YDH-704 reduces MDSC/Treg infiltration, enhances the infiltration and activation of CD8+ T cells, and inhibits tumor growth and lung metastasis. YDH-704 can be used for research on triple-negative breast cancer.

Biological Activity
|
HDAC10 0.02 μM (IC50) |
PAK1 0.05 μM (IC50) |
YDH-704 (compound 28a) potently and selectively inhibits purified PAK1 (IC50 = 0.05 μM) and HDAC10 (IC50 = 0.02 μM), and exhibits extremely low activity against other HDAC subtypes and most human kinases[1].
YDH-704 (8 μM; 6 h) directly binds to and stabilizes PAK1 and HDAC10 proteins in triple-negative breast cancer (TNBC) cells, confirming target binding at the cellular level[1].
YDH-704 (2-8 μM; 24 h) dose-dependently inhibits the activation of PAK1 and HDAC10, reduces phosphorylated PAK1 levels, and increases acetylated H3K27 levels in BT-549 and MDA-MB-231 triple-negative breast cancer (TNBC) cells[1].
YDH-704 (1 μM; 24 h) significantly increases the level of N8-AcSpd in MDA-MB-231 cells, confirming that it inhibits the polyamine deacetylase activity of HDAC10 in cells[1].
YDH-704 (24-48 h) potently inhibits the proliferation of BT-549 and MDA-MB-231 triple-negative breast cancer (TNBC) cells, with IC50 values ranging from 0.44 to 1.25 μM[1].
YDH-704 (2-8 μM; 24 h) inhibits the proliferation and long-term colony formation of triple-negative breast cancer (TNBC) cells in a dose-dependent manner; it downregulates PD-L1 expression in BT-549 and 4T1 cells in a dose-dependent manner via an HDAC10-dependent mechanism[1].
YDH-704 (2-8 μM; 24-48 h) inhibits the in vitro migration of triple-negative breast cancer (TNBC) cells in a dose-dependent manner[1].

YDH-704 (5-10 mg/kg; i.p.; 1-11 days) dose-dependently inhibits the growth of BT-549 triple-negative breast cancer (TNBC) xenografts in mice, with better efficacy than single-target inhibitors and their combination therapies; it also dose-dependently suppresses lung metastasis of triple-negative breast cancer in mice[1].
