ASX-173
Based on 1 Customer Validation
ASX-173 is an orally active inhibitor of asparagine synthetase (ASNS) (IC50 = 0.113 μM, Ki = 0.4 nM). ASX-173 enhances the anticancer activity of L-asparaginase (ASNase) (HY-P1923). ASX-173 disrupts nucleotide synthesis and induces leukemia cell cycle arrest, apoptosis and autophagy in leukemia cells in combination with ASNase. ASX-173 slows the growth of OCI-AML2 xenografts in combination with ASNase. ASX-173 is indicated for the study of acute lymphoblastic leukemia, acute myeloid leukemia, colorectal cancer, and other cancers.

ASX-173 (0.1-1000 nM,24 h) suppresses transcription of several endogenous Wnt target genes, including AXIN1, DKK1, CD133/PROM1, and MYC in HCT-116 cells[1].
ASX-173 exhibits potent cytotoxicity in DMEM medium but minimal to no effect when cells were cultured in RPMI-1640 in MDA-MB-231, SW620, A375 cells[1].
ASX-173 (0-500 nM) restores sensitivity to ASNase (HY-P1923) in ASNS-deficient RS4;11 cells[1].
ASX-173 (0-1250 nM) enhances the ASNS-positive cancer cell lines anticancer activity of ASNase in OPM-2, MOLP-8, AMO-1, Jurkat, H929, MV4;11, HT1080 cells[1].
ASX-173 (0-1500 nM) increases sensitivity combination with ASNaseWT or a glutaminase-deficient ASNase variant (ASNaseQ59L)13 in OVCAR-8, 92.1_D3, 92.1_M3 and OCI-AML2 cells[1].
ASX-173 (0-1500 nM) shows anticancer activity of majority of tested lines (such as: MV4;11, Jurkat, A172) under Asparagine (HY-N0667)-deprived conditions, using either asparagine-free medium or low-dose ASNase (0.025 IU/mL)[1].
ASX-173 (0-500 nM, 48 h) induces cell cycle arrest and activates apoptosis and autophagy under Asparagine-depleted conditions in MV4;11 leukemia and RS4;11_ASNS cells[1].
ASX-173 (80 nM, 24 h) disrupts nucleotide biosynthesis in OCI-AML2 leukemia cells treated with 0.025 IU/mL ASNase (Spectrila)[1].

Animal Model:NSG mice xenografted with luciferase-expressing OCI-AML2 leukemia cells (0.5 × 106)[1]
-
Dosage:50 mg/kg + ASNase (5,000 IU/kg, i.p.)
-
Administration:p.o., once a day, 2 weeks
-
Result:Suppressed leukemia progression, whereas monotherapy with either agent showed no significant effect.
Achieved a 7-day growth delay over the monotherapies, representing approximately 3-4 leukemia doubling times.
Improved overall survival, with all combination-treated mice living 7-10 days longer than those in other treatment groups.
