Butyzamide is an effective and oral Mpl activator. It is a novel non-peptide-based molecule with antagonistic effects on thrombopoietin (TPO) receptors, which promotes proliferation of human Mpl (hMpl) expression and mouse pro B cell line Ba F3. The phosphorylation of JAK2, STAT3, STAT5 and MAPK is induced. Butyzamide has been shown to help increase platelet levels in mouse xenotransplantation trials.

Stafib-2 is a potent and selective inhibitor of the transcription factor STAT5b, with IC50 values of 82 nM and 1.7 μM for STAT5b and STAT5a, respectively. Stafib-2 has poor cell permeability.

Cenisertib is A potent ATP-competitive multi-kinase inhibitor, showing inhibitory effects on the activity of Aurora-kinase-A B, ABL1, AKT, STAT5, FLT3, as well as kinase inhibitors of FER and its homolog. Cenisertib inhibits the growth of tumor mast cells (MCS) by inhibiting the activity of several different molecular targets. Cenisertib also inhibits tumor growth in pancreatic, breast, colon, ovarian and lung cancer and leukemia in xenograft models.

WP1066 is a inhibitor of JAK2 (IC50: 2.30 μM) and STAT3 (IC50: 2.43 μM) in HEL cells; shows activity to JAK2, STAT3 5, and ERK1 2, not JAK1 and JAK3. WP1066 has been used in trials studying the treatment of Melanoma, Brain Cancer, Solid Tumors, and Central Nervous System Neoplasms.

Pimozide (R6238) is a diphenylbutylpiperidine derivative and a dopamine antagonist with the antipsychotic property. Pimozide selectively inhibits type 2 dopaminergic receptors in the central nervous system (CNS), thereby decreasing dopamine neurotransmission and reducing the occurrence of the motor and vocal tics and delusions of parasitosis. In addition, this agent antagonizes alpha-adrenergic and 5-HT2 receptors.

Cryptotanshinone (Cryptotanshinon), a STAT3 inhibitor (IC50: 4.6 μM) in a cell-free assay, strongly inhibits phosphorylation of STAT3 Tyr705, with a little effect on STAT3 Ser727, but no inhibition for STAT1 nor STAT5.

BD750 is an effective immunosuppressant and a JAK3 STAT5 inhibitor, inhibits IL-2-induced JAK3 STAT5-dependent T cell proliferation(IC50 of 1.5 μM and 1.1 μM in mouse and human T cells, respectively)

HM43239 is an orally active and selective FLT3 inhibitor with IC 50 s of 1.1 nM, 1.8 nM and 1.0 nM for FLT3 WT, FLT3 internal tandem duplication (ITD) and FLT3 D835Y kinases, respectively. HM43239 directly inhibits the kinase activity of FLT3 as a reversible Type I inhibitor and effectively modulates downstream p-STAT5 and p-ERK. HM43239 also demonstrated inhibition of SYK, JAK1 2 and TAK1. HM43239 inhibits the proliferation and induces the apoptosis of leukemic cells [1] [2] [3].

AS2863619 free base enables the conversion of antigen-specific effector memory T cells into Foxp3+ regulatory T (Treg) cells. It is a potent, orally active CDK8 and CDK19 inhibitor (IC50s: 0.61 nM and 4.28 nM). STAT5 activation enhanced by AS2863619 free base inhibition of CDK8 19, which consequently activates the Foxp3 gene.

AK-068 is a STAT6 ligand with a Ki value of 6 nM, exhibiting at least 85-fold higher selectivity in binding to STAT6 over STAT5.

(R)-2-Phenylmorpholine is a fragment molecule that is commonly used in organic synthesis and can be involved in the synthesis of STAT5 6 PROTAC degraders or inhibitors.

DB-381831 is an organic phosphorus compound with a complex molecular structure that includes a benzothiophene ring, carboxyl group, diethoxyphosphoryl group, and difluoromethyl group. It may be used as an important intermediate or reagent in organic synthesis reactions. DB-381831 is involved in the synthesis of AK-2292, a STAT5 (Signal transducer and activator of transcription 5) small molecule degradator.

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.
