AG-012986 

AG-012986 is a pan-CDK inhibitor with K_i values of 44 nM (CDK1), 9.2 nM (CDK4), 94 nM (CDK2), and IC50 values of 22 nM (CDK5), 4 nM (CDK9). AG-012986 causes apoptosis of T-cells by targeting upstream kinases in the p38 Mitogen-activated protein kinase (MAPK) pathway and impairing cellular survival. AG-012986 induces cell cycle arrest, retinoblastoma protein hypophosphorylation, and reduces K_i-67 expression. AG-012986 exerts antiproliferative activity in tumor cells, demonstrates antitumor efficacy in human xenograft models, and causes retinal and peripheral neurotoxicity, plus immune cell toxicity. AG-012986 can be used for the research of colon carcinoma, non-small cell lung carcinoma, lung carcinoma, breast carcinoma, ovarian tumor, pancreatic carcinoma, osteosarcoma, lymphoma, leukemia, retinotoxicity^[1][2][3][4].

AG-012986 (72 h) potently inhibits proliferation of 18 human tumor cell lines with an average IC₅₀ of 120 nM, and displays IC₅₀ values <100 nM in 13 of these cell lines, independent of p53 and Rb status_[1].
AG-012986 (60-240 nM; 8-24 h) induces dose-dependent hypophosphorylation of Rb Ser795 in HCT116 human colon cancer cells after 24 hours of treatment, with maximal effects at >120 nM, but shows minimal effect after 8 hours_[1].
AG-012986 (30 nM-1 μM; 8-24 h) induces G1 phase arrest in HCT116 human colon cancer cells at 30 to 120 nM and G2-M phase arrest at ≥240 nM after 24 hours of treatment, but does not induce cell cycle arrest with <8 hours of exposure_[1].
AG-012986 (30-240 nM; 8-24 h) induces apoptosis in HCT116 human colon cancer cells with an IC₅₀ of ≈160 nM after 24 hours of treatment, but shows no apoptotic effect after 8 hours_[1].
AG-012986 (10-1000 nM; 8-320 h) shows time-dependent cytotoxicity in SW620 human colon carcinoma cells, with minimal activity after 8 hours, moderate activity (IC₅₀ = 300 nM) after 24 hours, and substantial cytotoxicity (IC₅₀ <100 nM) after ≥72 hours_[1].
AG-012986 exhibits binding inhibition of multiple CDK isoforms in a cell-free KINOMEscan assay, with similar IC₅₀ values to non-neurotoxic NVP-2 for CDK11, CDK16, and CDK17_[2].
AG-012986 (200-500 nM; 24 h) induces dose-dependent cytotoxicity in human MIO-M1 Müller cells, with significant decreases in cell viability and increases in cell death observed at 200 nM and maximal effects at 500 nM after 24 h of incubation_[2].
AG-012986 (250 nM; 16 h) induces rapid apoptosis/necrosis in primary human PBMCs, with 80% of cells showing dual PI/Annexin-V positivity_[3].
AG-012986 (50 nM-1 μM; 8-48 h) activates caspase-3/7 in primary human PBMCs in vitro in a dose-dependent manner, with peak activity occurring 16-24 h after treatment with 50 nM, 200 nM, or 1 μM_[3].
AG-012986 (50 nM-200 nM; 8 h) induces cleavage of caspase-3 and PARP in primary human PBMCs following 8 h treatment with 50 nM or 200 nM, confirming caspase-mediated apoptosis_[3].
AG-012986 (10 nM-500 nM; 16 h) exhibits greater cytotoxicity in primary human PBMCs than staurosporine after 16 h treatment with 10-500 nM, as measured by reduced ATP content and increased caspase-3/7 activity_[3].
AG-012986's (50 nM-250 nM; 20 min) toxicity profile is altered by acute stimulation of T cells_[3].
AG-012986 (20 nM-500 nM) inhibits α-CD3-induced proliferation in purified primary human T cells pretreated by AG-012986 followed by 24 h α-CD3 antibody stimulation, while α-CD3 stimulation decouples this antiproliferative activity from AG-012986-induced toxicity_[3].
AG-012986 (20 nM-500 nM; 48 h) inhibits α-CD3-induced IL-2 production in purified primary human T cells in a dose-dependent manner, with a fivefold reduction observed at 20 nM_[3].
AG-012986 (50-250 nM; 20 min pretreatment) inhibits both basal and α-CD3-induced p38 phosphorylation in purified primary human T cells pretreated with 50 nM or 250 nM for 20 min followed by 16 h incubation with or without stimulation_[3].
AG-012986 (250 nM; 16 h) causes rapidly apoptosis in PBMCs and occurs independently of any cell division_[4].
AG-012986 (50-200 nM; 8 h) induced the presence of p17 and p19 and the cleaved form of PARP_[4].
