Farudodstat (ASLAN003) 是一种具有口服活性,有效的二氢乳清酸脱氢酶 (DHODH) 抑制剂,对人 DHODH 酶的IC50为 35 nM。Farudodstat 通过激活 AP-1 转录因子来抑制蛋白质合成。Farudodstat 可以诱导凋亡 (apoptosis),并在急性髓样白血病 (AML) 异种移植小鼠中大大延长其生存期。
生物活性 | Farudodstat (ASLAN003) is an orally active and potentDihydroorotate Dehydrogenase(DHODH)inhibitor with anIC50of 35 nM for human DHODH enzyme. Farudodstat inhibits protein synthesis via activation ofAP-1transcription factors. Farudodstat inducesapoptosisand substantially prolongs survival in acute myeloid leukemia (AML) xenograft mice[1][2]. |
IC50& Target | IC50: 35 nM (human DHODH enzyme)[1] |
体外研究 (In Vitro) | Farudodstat (0.01-100 μM; for 48 hours) inhibits leukemic cell proliferation. The cell viability is maintained at ~50% at Farudodstat 1 μM and higher[1]. Farudodstat (0.5, 1 μM; for 48 hours) significantly increases cleaved caspase 8[1]. Farudodstat (2, 4 μM; for 96 hours) decreases viability and induces differentiation in primary acute myeloid leukemia blasts and myelodysplastic syndrome samples[1]. Farudodstat (1, 2 μM; pretreatment 1 h before OPP for 1 h) inhibits protein synthesis, as demonstrated by the reduced incorporation of O-propargyl-puromycin (OPP) at protein translation sites in both MOLM-14 and KG-1 cells. Farudodstat causes the downregulation of EIF4B, and RPL6 proteins[1].
Cell Proliferation Assay[1] Cell Line: | THP-1, MOLM-14 and KG-1 cells | Concentration: | 0.01, 0.1, 1, 10, 100 μM | Incubation Time: | For 48 hours | Result: | Inhibited leukemic cell proliferation of THP-1, MOLM-14 and KG-1 with IC50values of 152 nM, 582 nM, and 382 nM, respectively. |
Western Blot Analysis[1] Cell Line: | KG-1 and MOLM-14 cells | Concentration: | 0.5, 1 μM | Incubation Time: | For 48 hours | Result: | Significantly increased cleaved caspase 8, increased leakage of cytochrome c from mitochondria into the cytosol and induced cleaved caspase-3 and -7. |
|
体内研究 (In Vivo) | Farudodstat (50 mg/kg; oral gavage; once daily; from the day 3 to 30) substantially reduces the number of disseminated tumors and prolongs survival[1].
Animal Model: | Female NOD.Cg-PrkdcscidIl2rgtm1Wjl/SzJ, NGS mice (4-6 weeks old) with MOLM-14 cells[1] | Dosage: | 50 mg/kg | Administration: | Oral gavage; once daily; from the day 3 to 30 | Result: | Substantially reduced the number of disseminated tumors and the size of these tumors. Survival was significantly prolonged. |
