| Targets |
The primary target of CWI1-2 hydrochloride is IGF2BP2, an m6A reader protein that recognizes and binds to N6-methyladenosine (m6A)-modified mRNAs. IGF2BP2 promotes the stability and translation of its target mRNAs, which include oncogenes involved in cancer cell proliferation and survival. By binding to IGF2BP2 and inhibiting its interaction with m6A-modified target transcripts, CWI1-2 hydrochloride reduces the expression of these oncogenes, inducing apoptosis and differentiation. The compound shows promising anti-leukemic effects.

|---|---|
| ln Vitro |
CWI1-2 hydrochloride (0–1 μM, 24 h) exhibits good anti-leukemia activity [1].
In vitro studies demonstrate that CWI1-2 hydrochloride binds IGF2BP2 and inhibits its interaction with m6A-modified target transcripts. The compound induces apoptosis and differentiation and shows promising anti-leukemic effects. CWI1-2 hydrochloride is an effective IGF2BP2 inhibitor. No detailed IC50 or EC50 values have been published in the available literature. |
| ln Vivo |
In BMT receptor B6.SJL (CD45.1) mice, CWI1-2 (5 mg/kg, iv, once daily, 7–10 days) hydrochloride can dramatically postpone the onset and survival time of leukemia without having a noticeable effect on body weight [1].
In vivo, CWI1-2 (5 mg/kg, i.v., once daily, 7-10 days) significantly delays the onset of leukemia and prolongs survival time in BMT recipient B6.SJL (CD45.1) mice without significant effects on body weight. These results demonstrate the in vivo efficacy of CWI1-2 hydrochloride in a leukemia model. The compound's ability to inhibit IGF2BP2 and induce apoptosis and differentiation contributes to its anti-leukemic activity. |
| Enzyme Assay |
The IGF2BP2 binding activity of CWI1-2 hydrochloride can be assessed using in vitro binding assays. In a typical assay, recombinant IGF2BP2 protein is incubated with m6A-modified RNA probes and varying concentrations of CWI1-2 hydrochloride. The disruption of the IGF2BP2-RNA interaction is measured using fluorescence polarization, surface plasmon resonance, or RNA pull-down assays. The compound's ability to inhibit IGF2BP2 binding to m6A-modified transcripts is assessed.

| Cell Assay |
Apoptosis Analysis[1]
Cell Types: MonoMac6, MOLM13 Tested Concentrations: 0-1 μM Incubation Duration: 24 h Experimental Results: Induced significant cell differentiation and apoptosis in a concentration-dependent manner in IGF2BP2-high cells but not in IGF2BP2-low cells. decreased Gln uptake and impaired mitochondrial function, resulting in decreased ATP production in AML cells. Dramatically inhibited the colony-forming ability of MA9- induced leukemic mouse blasts and greatly impairs the self-renewal of LSC/LIC. The cellular activity of CWI1-2 hydrochloride is assessed using leukemia cell lines. Cells are treated with varying concentrations of CWI1-2 hydrochloride. IGF2BP2 target gene expression is measured by qPCR or Western blotting. Apoptosis is assessed by annexin V/propidium iodide staining or caspase activation assays. Differentiation is assessed by measuring cell surface markers or morphological changes. Cell viability is measured using MTT or CellTiter-Glo assays. |
| Animal Protocol |
CWI1-2 hydrochloride has been evaluated in a mouse model of leukemia. In these studies, the compound is administered intravenously at 5 mg/kg once daily for 7-10 days. The onset of leukemia and survival time are monitored. The compound significantly delays the onset of leukemia and prolongs survival time without significant effects on body weight. These results demonstrate the in vivo efficacy of CWI1-2 hydrochloride.
|
| ADME/Pharmacokinetics |
No detailed pharmacokinetic data has been published for CWI1-2 hydrochloride. The compound has a molecular weight of 556.23 and a molecular formula of C22H18Cl4N6O3. It is soluble in DMSO at 125 mg/mL (224.73 mM). The compound is typically stored at 4°C, sealed and protected from moisture. Further studies would be needed to characterize its absorption, distribution, metabolism, and excretion properties.
|
| Toxicity/Toxicokinetics |
No detailed toxicity data has been published for CWI1-2 hydrochloride. In the mouse leukemia model, the compound did not cause significant effects on body weight at the tested dose of 5 mg/kg. As an IGF2BP2 inhibitor, the compound may have on-target effects on m6A-mediated gene regulation in normal cells. Comprehensive toxicology studies would be required to evaluate its safety profile for potential therapeutic development.
