JP-11646
Based on 1 Customer Validation
JP-11646 is a pan-PIM inhibitor with increased potency against PIM2 (IC50 = 0.5 nM). JP11646 is freely reversible and ATP non-competitive. JP-11646 results in a decrease of PIM1, 2, and 3 mRNA. JP-11646 can effectively inhibit cell viability in small cell lung cancer (SCLC) and large cell neuroendocrine carcinomas of the lung (LCNEC). JP-11646 can cause a decrease in p-4EBP-1 protein, increasing the cleavage of caspases while decreasing caspase-3. JP-11646 induces apoptosis or necroptosis in cells. JP-11646 leads to reductions in MYC paralogs. JP-11646 can be used for the study of SCLC, LCNEC, human acute leukemia (AML), multiple myeloma (MM), and triple-negative breast cancer (TNBC).

In Vitro
JP11646 (0.005 to 10 μM, 72 h) inhibits the proliferation of all tested cancer cell lines in a concentration-dependent manner, including head and neck cancer FaDu, ovarian cancer SK-OV-3, breast cancer MDA-MB-231 and BT549, prostate cancer PC-3, liver cancer HepG2, PDAC MIAPaCa-2 and PANC1, colorectal cancer DLD-1 and HT29, and NSCLC H1650, H661, H460 and A549 cell lines[3].
JP11646 (100-200 nM, 24 h) selectively downregulates the protein expression level of PIM2, but has no effect on PIM1 and PIM3, and induces the expression of the apoptosis marker cleaved PARP in MDA-MB-231 and BT549 cells[3].
JP11646 (100-200 nM, 48 h) significantly increases the apoptosis rate of MDA-MB-231 and BT549 cells[3].
JP11646 (20-200 nM, 0-24 h) gradually reduces the levels of p4EBP1 (S65) and pBAD (S112) in MM1.S and U266 cells over time, as do the total levels of these proteins. Furthermore, the levels of the potent phosphorylates form of the anti-apoptotic factor MCL1 (Ser159/Thr163) decrease in a dose-dependent manner[4].
JP11646 (0-1 μM, 72 h) shows the strongest antiproliferative effect against the MF characteristic cell line MM1.S (GI50 = 5 nM)[4].
JP11646 (20-200 nM, 24 h) can reverse (recombinant IL-6) rIL-6-induced PIM2 upregulation in MM1.S and U266 cells, while IL-6 does not affect PIM2 mRNA levels[4].
JP11646 (10-20 nM, 48 h) reverses the chemoprotective effect mediated by CD28 activation or DC co-culture; CTLA4-Ig enhances the cytotoxicity of JP11646[4].
JP11646 (20-200 nM, 0-24 h) dose- and time-dependently inhibits CD28-induced NF-κB activity in MM1.S and RPMI8226 cells[4].

Protocols
-
RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.
-
Apoptosis
Apoptosis, also called programmed cell death, is generally characterized by distinct morphological characteristics.
-
TUNEL staining for apoptotic DNA fragmentation
TUNEL staining detects DNA strand breaks by using terminal deoxynucleotidyl transferase to add labeled nucleotides to exposed 3′-OH DNA termini, generating either microscopic staining in fixed cells or tissue sections, or fluorescence/cytometric signal in cell suspensions. TUNEL positivity reflects DNA fragmentation but should not be interpreted alone as definitive apoptosis, because TUNEL can also label necrotic, autolytic, mechanically damaged, or DNA-repair-associated DNA breaks.
-
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.
-
Annexin V plus membrane-impermeant dye apoptosis staining
Annexin V-based apoptosis assays rely on the detection of phosphatidylserine (PS) externalization from the inner leaflet of the plasma membrane to the outer leaflet, an early biochemical hallmark of apoptosis. Fluorescently labeled Annexin V binds PS in a calcium-dependent manner, enabling identification of early apoptotic cells by flow cytometry or fluorescence microscopy. When combined with a membrane-impermeant DNA-binding dye (e. g. , propidium iodide), this approach allows discrimination between viable (Annexin V−/dye−), early apoptotic (Annexin V+/dye−), and late apoptotic or necrotic (Annexin V+/dye+) cell populations by assessing membrane integrity and PS exposure.

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

CCK-8/WST-8 Cell Proliferation Assay
The CCK-8/WST-8 assay is based on the reduction of the water-soluble tetrazolium salt WST-8 to a water-soluble formazan product by cellular dehydrogenases in metabolically active cells, where the generated formazan amount is proportional to the number of living cells and is quantified by measuring absorbance in the visible range, providing a colorimetric readout for cell viability and proliferation assessment. This class of tetrazolium-based assays improves upon earlier MTT-based systems by producing a water-soluble formazan, eliminating the need for organic solubilization steps and enabling direct spectrophotometric measurement in culture medium.
-
MTT Cell Proliferation Assay
The MTT assay is a colorimetric endpoint assay for estimating viable cell number, cell growth, cytotoxicity, or cell activation in cultured mammalian cells. Living cells reduce the yellow tetrazolium salt MTT into purple/blue formazan, while dead cells do not generate the same signal; the resulting color can be quantified with a multiwell spectrophotometer. MTT reduction is commonly interpreted as a readout of metabolic activity that often correlates with viable cell number, but it should not be treated as a direct cell-counting method unless the assay is optimized for the cell type and experimental condition. Studies show that MTT reduction can involve mitochondrial and non-mitochondrial reducing systems, and formazan may accumulate in intracellular lipid droplets rather than simply marking mitochondria.

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.
-
Cell Viability Determination by MTT Colorimetric Assay
The following protocol uses the MTT colorimetric assay as a classic literature-established method for assessing cell viability/metabolic activity in cultured mammalian cells. MTT[3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] is reduced by metabolically active cells to a colored formazan product; the amount of formazan is quantified spectrophotometrically and provides an indirect measure of metabolically active viable cells. Importantly, MTT reduction reflects cellular oxidoreductase/metabolic activity rather than an absolute direct count of living cells, so changes in cellular metabolism can alter the signal independently of cell number.
