Orally active, highly potent and selective lysine acetyltransferase KAT6A inhibitor with anti-cancer efficacy in vivo.PF-9363 (CTx-648) is an orally active, highly potent and selective lysine acetyltransferase KAT6A inhibitor (KAT6A Ki = 0.27 nM; KAT6B/7/5/8 Ki = 2.4/70/420/670 nM). PF-9363 selectively inhibits H3K23 acetylation (ZR-75-1 H3K23Ac/H3K14Ac IC50 = 0.85/120 nM) and exhibits anti-proliferation potency against high KAT6A-expressing estrogen receptor signaling-positive (ER+) breast cancer cells in cultures (ZR-75-1 IC50 = 0.37 nM) and in mice in vivo (complete inhibition of ZR-75-1 xenograft tumor growth by 0.03 mg/kg/day p.o.) by downregulating cancr ER signaling, cell cycle and MYC transcriptional programs.
