M3541
Based on 1 Customer Validation
M3541 is an orally effective DNA-dependent protein kinase (DNA-PK) inhibitor. M3541 inhibits ionizing radiation-induced ATM autophosphorylation and phosphorylation of downstream substrates (KAP1, CHK2, p53), blocks DSB end resection and homologous recombination repair, and simultaneously induces non-homologous end joining, G2-M phase arrest, polyploidization, and cell death. M3541 can be used for research on solid tumors, acute myeloid leukemia, non-small cell lung cancer, triple-negative breast cancer, etc..

In Vitro
M3541 is a potent and selective ATP-competitive ATM kinase inhibitor with an IC50 of 0.25 nM[1].
The inhibitory activity of M3541 requires wild-type ATM kinase and functional signaling, with an average IC50 of 71 nM in wild-type ATM cell lines and 670 nM in mutant ATM cell lines[1].
M3541 (1 μM) alone causes growth inhibition in IMR90 and WI38 fibroblast cell lines, but induces only slight cell death[5].
M3541 (0.125-3 μM; 1 h) effectively inhibits IR-induced ATM catalytic activity and downstream signaling in A549 cells[1].
M3541 (1 μM; 1 h) significantly impairs DSB repair in A549 cells, leading to the accumulation of unrepaired DSBs[1].

M3541 alone (up to 1.0 μM) shows minimal toxicity in A549 and NCI-H460 cells but sensitizes these cells to ionizing radiation[3].

M3541 sensitizes multiple tumor cell lines to ionizing radiation and a topoisomerase inhibitor in vitro[7].
M3541 (1 μM; 1 h) effectively inhibits the catalytic activity of ATM and its downstream signaling in irradiated A549, A375, and RKO cancer cells, with 1 μM causing over 90% inhibition[9].
M3541 (1 μM; 1 h) initially suppresses IR-induced γH2AX foci but leads to the accumulation of numerous unrepaired DSBs at 24 h in A549 cells[9].

M3541 (1 μM) prevents complete cell cycle arrest induced by DNA-PK inhibition in irradiated A375 cells, confirming the role of ATM in this process[6].
M3541 (1 μM; 1 h) inhibits the function of ATM in cell cycle checkpoint control in irradiated A549 cells, causing cell cycle arrest to shift primarily toward G2/M[9].
M3541 (1 μM; 6 days) alone has no effect on A549 parental cells and enhances M6620-induced cell death in A549 p53-deficient cells[5].

Protocols

Kinase activity and phosphorylation assays
Kinase activity assays measure the ability of kinases to transfer phosphate groups from ATP to specific substrates, while phosphorylation assays detect the presence and levels of phosphorylated proteins. Common methods include radiolabeled ATP incorporation (e. g. ,), ADP release detection via bioluminescence (e. g. ,[3]), enzyme-linked immunosorbent assays (ELISA) for phospho-specific epitopes (e. g. ,[6]), and microtiter-based formats for high-throughput screening (e. g. ,[8]). The ADP-Glo assay quantifies kinase activity by measuring ADP produced during phosphorylation using a luciferase-based system. Radiometric assays involve autoradiography or scintillation counting after incorporation of 32P-labeled ATP into substrate proteins. ELISA-based approaches rely on phospho-specific antibodies to detect activated kinases in cell lysates or purified samples.
-
Western Blot
Western blotting (WB) is a commonly used experimental method in molecular biology, biochemistry, and immunogenetics for identifying and quantifying target proteins. It combines gel electrophoresis with immunoassay, enabling researchers to analyze protein expression, post-translational modifications, and molecular weight.
-
CRISPR-Cas9 HDR knock-in/precise editing
CRISPR-Cas9 HDR knock-in uses a guide RNA to direct Cas9 to a genomic target adjacent to a PAM, where Cas9 creates a double-strand break; if a donor DNA template with homology to the cut region is present, cellular HDR can copy the donor sequence into the genome, producing a precise substitution, tag, reporter, or insertion rather than an indel. The readout is the fraction of alleles or cells carrying the intended donor-derived edit, measured by junction PCR, restriction-fragment analysis, Sanger sequencing, amplicon deep sequencing, flow cytometry for reporter knock-in, or clone genotyping; NHEJ indels and partial or non-HDR insertions are measured in parallel because they compete with or confound precise HDR outcomes.
-
Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
-
Mammalian live/dead viability and cytotoxicity staining
Live/dead viability and cytotoxicity staining assays are based on the simultaneous detection of intracellular esterase activity in metabolically active (viable) cells and membrane integrity loss in non-viable cells. In commonly used dual-staining approaches, membrane-permeant fluorogenic substrates are converted by intracellular esterases into fluorescent products in live cells, while impermeant DNA-binding dyes selectively enter cells with compromised plasma membranes and label nucleic acids in dead or dying cells, enabling discrimination between viable and non-viable populations by fluorescence microscopy or flow cytometry.
-
Apoptosis Solutions
Apoptosis is a regulated, generally non-lytic cell-death pathway that removes unwanted, damaged, infected, or abnormal cells through coordinated morphological changes, caspase activation, DNA fragmentation, and membrane remodeling. The intrinsic apoptosis pathway is controlled mainly by mitochondrial outer membrane permeabilization, BCL-2 family proteins, cytochrome c release, apoptosome formation, caspase-9 activation, and downstream executioner caspase-3/7 activation. The extrinsic apoptosis pathway is initiated by death receptors such as Fas, TNFR, and TRAIL receptors, which recruit adaptor proteins and activate caspase-8 before engaging executioner caspases or mitochondrial amplification through BID cleavage. Apoptosis is linked to many phenotypes, including cancer cell killing, tissue homeostasis, immune regulation, neurodegeneration, infection response, and treatment-induced cytotoxicity; unresolved questions include how apoptosis interacts with necroptosis, pyroptosis, ferroptos
-
Protocol for Kinase activity and phosphorylation assays
Kinase activity assays measure transfer of phosphate from ATP to a protein or peptide substrate, generating phosphorylated substrate, ADP, or incorporated radiolabeled phosphate as the readout; phosphorylation assays measure site-specific phosphorylation in cells or tissues as a proxy for kinase-pathway activation, inhibition, or substrate regulation. Phosphorylation can be detected by phospho-specific Western blot, immunoprecipitation kinase assay, phospho-immunofluorescence, phospho-flow cytometry, luminescent ADP detection, radiolabeled ATP incorporation, or reporter-based pathway assays, and these readouts can be applied to cancer cells, primary neurons, mouse tumors, organoids, inflammatory macrophages, ferroptosis studies, and mitophagy studies when the kinase target is biologically relevant.

Breast Cancer Modeling
Breast cancer is a heterogeneous cancer, and it has been distinguished into four subtypes: luminal A, luminal B, HER2-positive and basal-like. Molecular mutations, epigenetic alterations, hormone exposure and immune microenvironment are related to the progression of breast cancer.
