TH1834 dihydrochloride is a specific Tip60 histone acetyltransferase inhibitor. TH1834 dihydrochloride causes apoptosis and enhances DNA damage in breast cancer.
ITH15004 is a non-nucleotide antagonist of the purinergic P2X7receptor (IC50= 9 μM in HEK293 cells expressing the human receptor).1It inhibits ATP-induced currents inX. laevisoocytes expressing the human P2X7receptor when used at a concentration of 100 μM. ITH15004 (1 μM) decreases IL-1β release from LPS-primed, ATP-stimulated isolated mouse peritoneal macrophages. It has high permeability in a parallel artificial membrane permeability assay (PAMPA). 1.Calzaferri, F., Narros-Fernández, P., de Pascual, R., et al.Synthesis and pharmacological evaluation of novel non-nucleotide purine derivatives as P2X7 antagonists for the treatment of neuroinflammationJ.

TH1834 is a selective inhibitor of the Tip60 (KAT5) histone acetyltransferase (HAT). It effectively induces apoptosis and promotes DNA damage in breast cancer cells. Notably, TH1834 does not influence the activity of the MOF histone acetyltransferase, which is structurally related. Overall, TH1834 exhibits potent anticancer activity.
