Farudodstat (ASLAN003) is an orally active and potent inhibitor of DHODH (Human Dihydroorotate Dehydrogenase) with antitumor activity, showing potential as a first-in-class candidate in AML [Acute Myeloid Leukemia].

PROTAC METTL3 degrader 1 (Compound KH12) is a VHL-based degrader of METTL3, demonstrating a DC50 of 220 nM in MOLM-13 cells. This compound inhibits the METTL3 14 complex with an IC50 of 341 nM and exhibits antiproliferative activity against AML cells.

MK256 is a novel CDK8 inhibitor that demonstrates potent antitumor activity against AML by inhibiting the STAT pathway. It induces differentiation and maturation while inhibiting proliferation in AML cell lines. MK256 decreases the phosphorylation of STAT1(S727) and STAT5(S726) and reduces mRNA expression of MCL-1 and CCL2 in these cells. Its efficacy is validated in the MOLM-14 xenograft model, showing phosphorylation inhibition of STAT1(S727) and STAT5(S726) post-treatment. Pharmacokinetic studies in the MOLM-14 model reveal a dose-dependent inhibition of the STAT pathway. Both in vitro and in vivo studies confirm that MK256 effectively downregulates the STAT pathway.

JCS-1 is a potent DcpSPROTAC degrader. It non-covalently binds to DcpS via an RG3039-based warhead and recruits the E3 ligase VHL. JCS-1 facilitates the ubiquitination and degradation of DcpS at nanomolar concentrations, with a DC50 of 87 nM in MOLM-14 cells. This compound can be utilized in research on acute myeloid leukemia and other DcpS-dependent genetic disorders.

MTHFD2-IN-5 (Compound 16e) is a selective inhibitor of MTHFD2 with an IC50 of 66 nM. It inhibits the proliferation of MOLM-14 cells with a GI50 of 720 nM and demonstrates antitumor activity in mouse models.

FLT3-IN-28 (Compound 12y) is an orally active FLT3 inhibitor with antitumor properties. It selectively targets cancer cells with FLT3 internal tandem duplication (ITD) mutations, demonstrating IC50 values of 85, 290, 130, 65, and 220 nM against BaF3-FLT3-ITD, BaF3-TEL-VEGFR2, MV4-11, MOLM-13, and MOLM-14 cell lines, respectively. These lines include acute myeloid leukemia (AML) cells harboring FLT3-ITD mutations such as MV4-11 and MOLM-13 14. The compound also reduces phosphorylation levels of FLT3 and STAT5 in MOLM-13 cells, leading to cell cycle arrest and apoptosis. With an oral bioavailability of 19.2% in SD rats, FLT3-IN-28 extends survival in a dose-dependent manner in MOLM-13 xenografted NSG mouse models. It holds promise for research in FLT3-ITD-related cancer studies.

QXG-6442 is a molecular glue degrader targeting CK1α, demonstrating a degradation potency with a DC50 of 5.7 nM and a Dmax of 90%. In the MOLM-14 cell line, QXG-6442 induces antiproliferative effects.

BPR1J-097, a new-type small molecule FLT-3 inhibitor(IC50=11±7 nM), is with great anti-tumor activities in vivo.

CDK8-IN-14 (compound 12) effectively inhibits CDK8, demonstrating an IC50 of 39.2 nM, and exhibits potent anti-AML cell proliferation effects, with a GC50 value of 0.02±0.01μM in MOLM-13 cells and 0.03±0.01μM in MV4-11 cells [1].
