ZS34
ZS34 is a potent, orally active, and selective MAT2A inhibitor with an IC50 of 13.7 nM, displaying minimal hERG and UGT1A1 liabilities. ZS34 selectively suppresses the growth of methylthioadenosine phosphorylase (MTAP)-deficient cancer cells by inhibiting SAM synthesis, reducing SDMA levels, and inducing DNA damage. ZS34 exhibits antitumor efficacy in a HCT116 MTAP-/- xenograft mouse model. ZS34 can be used for the research of MTAP-deficient cancer.

MAT2A 13.7 nM (IC50) |
ZS34 (10 days) inhibits the proliferation of MTAP deficiency cells (NCI-H838, NCI-H1437, MCF-7, MDA-MB-231 and MIA PaCa-2 cells) with IC50s of 1.70, 386, 38.1, 37.2, and 115 nM, respectively, exhibiting selectivity over MTAP proficiency cells (A-375, AsPC-1, DU145, NCI-H460 and NCI-H520) with IC50s >10000 nM[1].
ZS34 (10 days) exhibits potent antiproliferative effects against HCT116 MTAP-null cells (IC50 = 124 nM) but weak activity against WT HCT116 cells (IC50 > 10000 nM), demonstrating excellent selectivity inhibition with a selective indices (SI) exceeding 80.6[1].
ZS34 (0-10 μM; 96 h) selectively induces DNA damage in MTAP-deficient HCT116 cells through MAT2A inhibition[1].
ZS34 binds to the allosteric site of the MAT2A dimer, forming hydrogen bonds with Arg313 and a coordinated water molecule, and engaging in π-π stacking with Phe20, Trp274, and Phe18, while its ortho-methyl group participates in a CH-π interaction with Phe333[1].

Cell Line:HCT116 (MTAP-/-) and HCT116 (WT)
-
Concentration:0, 0.1, 1 μM
-
Incubation Time:96 h
-
Result:Induced a dose-dependent decrease in the SDMA level, in HCT116 MTAP-/- cells, but not in HCT116 WT cells.
Induced a marked increase in γH2AX levels, a marker of DNA damage, in HCT116 MTAP-/- cells, but not in HCT116 WT cells.
