CID-078
Based on 1 Customer Validation
CID-078 is an orally active macrocyclic cyclin A and cyclin B inhibitor. CID-078 binds cyclin hydrophobic patches, disrupting interactions of cyclin A-Cdk2 with E2F1 and cyclin B-Cdk1 with Myt1, and selectively targets RxL binding motifs to block complex-substrate interactions. CID-078 induces DNA damage, G2/M cell cycle arrest, apoptosis, mitotic catastrophe, spindle assembly checkpoint activation, and neomorphic cyclin B-CDK2 complex formation, driving synthetic lethality in E2F-driven cancer cells. CID-078 can be used for the research of small cell lung cancer, non-small cell lung cancer, triple negative breast cancer, advanced solid tumors, luminal HR+/HER2- breast cancer, RB1-altered solid tumors, and neuroblastoma.

In Vitro
CID-078 induces antiproliferation in 46 SCLC and 104 NSCLC cell lines, with enhanced activity observed in cells with high E2F and G2M hallmark pathway scores and/or elevated cyclin B1 and separase expression[1].
CID-078 (4-8 days) inhibits proliferation of a broad panel of solid tumor cell lines, with significantly greater potency (lower GI50 values) in RB1-altered cell lines, and heightened sensitivity correlated with high E2F targets and G2/M checkpoint pathway scores in SCLC, TNBC, and NSCLC cell lines[3].
CID-078 binds to the hydrophobic patch/RxL binding site of cyclin-CDK complexes, inhibits E2F1-cyclin A-CDK2 and MYT1-cyclin B-CDK1 interactions, and induces replication stress, DNA damage, and mitotic catastrophe in E2F1-high tumor cells[3].
CID-078 (72 h) inhibits growth of established neuroblastoma cell lines with GI50 values ranging from 0.001 μM (SKNSH) to 10 μM (SY5Y WT, GIMEN, TR14, SKNAS)[4].
CID-078 (72 h) sensitizes CDKN2A-inactivated SH-SY5Y neuroblastoma cells, resulting in GI50 values of 55 nM (C7.3 clone) and 6 nM (C8.10 clone) compared to >10 μM in wild-type SH-SY5Y cells[4].
CID-078 (120 h) inhibits growth of patient-derived neuroblastoma organoid models with GI50 values ranging from 0.01 μM to 1 μM[4].
CID-078 (100 nM; 24 h) induces G2/M-phase cell cycle arrest in neuroblastoma cell lines, with percentage increases in G2/M population ranging from 52% (SY5Y C7.3) to 632% (SKNSH) compared to DMSO control[4].
CID-078 (3-200 nM; 24 h) induces spindle assembly checkpoint activation (phospho-BUBR1), DNA damage (phospho-γH2AX), and G2/M phase marker expression (phospho-FoxM1) in neuroblastoma cell lines and hTERT-RPE1 healthy control cells[4].

Detection of 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.
-
Flow cytometric DNA-content cell-cycle staining
Flow cytometric DNA-content cell-cycle staining measures the fluorescence intensity of DNA-bound fluorochromes in single cells or nuclei to estimate DNA content distributions, allowing assignment of populations to G0/G1, S, and G2/M phases by DNA histogram deconvolution. Propidium iodide (PI) intercalates into DNA, and PI fluorescence is proportional to cellular DNA content when staining is performed under conditions that make DNA accessible and minimize non-DNA signal. Cells with G2/M DNA content are expected to show approximately twice the fluorescence intensity of G0/G1 cells, while S-phase cells occupy intermediate fluorescence values. PI-based DNA-content analysis can also detect cells with fractional DNA content, often reported as sub-G1, when DNA fragmentation and extraction during staining reduce retained DNA signal in apoptotic cells. DAPI is an alternative DNA fluorochrome for univariate DNA-content analysis, while bivariate approaches combining DNA content with proliferation

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.

BrdU Incorporation Assay
Bromodeoxyuridine (BrdU) incorporation assay is based on the principle that BrdU, a thymidine analog, is incorporated into newly synthesized DNA during the S phase of the cell cycle, thereby serving as a marker of DNA replication and cellular proliferation. Incorporated BrdU can be detected using anti-BrdU antibodies following DNA denaturation, enabling visualization or quantification of proliferating cells through immunochemical detection methods such as immunofluorescence or immunohistochemistry.

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 Cell Cycle
Cell-cycle analysis by flow cytometry measures DNA content in single cells to estimate the fraction of cells in G0/G1, S, and G2/M phases. Propidium iodide intercalates into DNA, and after RNA removal with RNase, fluorescence intensity reflects cellular DNA content: 2N cells are assigned to G0/G1, cells between 2N and 4N to S phase, and 4N cells to G2/M. DNA-content analysis alone cannot reliably separate G0 from G1 or G2 from M. Ki-67 can distinguish quiescent G0 cells from cycling cells, EdU or BrdU incorporation marks active DNA synthesis in S phase, and phospho-histone H3 staining identifies mitotic cells within the 4N population.

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.

Genotoxicity/Mutagenicity Study
The bacterial reverse mutation assay detects point mutations that restore amino-acid prototrophy in auxotrophic Salmonella typhimurium or Escherichia coli tester strains; after exposure to a test article, mutagenic activity is read out as an increased number of revertant colonies on minimal agar compared with the vehicle control. The assay uses tester strains with different mutation targets so that base-substitution and frameshift mutagens can be detected, and testing is performed with and without exogenous mammalian metabolic activation because some chemicals require biotransformation to become mutagenic.
