Cell experiment: | MZ-CRC-1 (MEN2B) and TT (MEN2A) cells are treated with AD80 (0.2 nM to 20 μM) for 7 days and cell viability is quantitated by MTT assay[1]. |
Animal experiment: | Mice:Mice showing established growing tumors are separated into vehicle or drug treatment groups. A similar range of tumor sizes is selected for each experiment (vehicle vs AD57; vehicle vs AD80 vs Vandetanib). Vehicle, AD57 (20 mg/kg), AD80 (30 mg/kg), or Vandetanib (50mg/kg) are administered by oral gavage (PO; per os or by mouth) once daily, five times a week. Tumor and body weight measurements are performed 3 times a week[2]. |

AD80, a multikinase inhibitor, shows strong activity against human RET (c-RET), BRAF, S6K, and SRC but were much less active than either AD57 or AD58 against mTOR. The IC50 value for RET is 4 nM.
AD80 prevents the phosphorylation of RET as well as of extracellular signa-regulated kinase (ERK), AKT, and S6K at low nanomolar concentrations in kinesin family member 5B (KIF5B)-RET-expressing Ba/F3 cells. Treatment with AD80 results in up-regulation of genes that are typically repressed by active KRAS. On the contrary, genes that are activated by KRAS were down-regulated[1]. On the basis of in vitro human kinase profiles, AD80 and AD81 inhibit RET, RAF, SRC and S6K, with greatly reduced mTOR activity relative to AD57 and AD58. AD80 inhibits proliferation of MZ-CRC-1 and TT thyroid cancer cells in culture, probably through the induction of apoptosis[2].
AD80 is a highly potent RET inhibitor with a favorable pharmacokinetic profile in clinically relevant RET fusion-driven tumor models. AD80 potently shrinks RET-rearranged tumors in patient-derived xenografts. A pronounced reduction in phosphorylation of RET as well as AKT and ERK in tumors treated with AD80 (25 mg/kg) is observed but not in tumors treated with cabozantinib or vandetanib[1].

AD80, a multikinase inhibitor, as a potential drug candidate for colorectal cancer therapy
Life Sci 2022 Nov 1;308:120911.PMID:36030982DOI:10.1016/j.lfs.2022.120911.
Aims: Colorectal cancer (CRC) is a very heterogeneous disease. One of its hallmarks is the dysregulation of protein kinases, which leads to molecular events related to carcinogenesis. Hence, kinase inhibitors have been developed and are a new strategy with promising potential for CRC therapy. This study aims to explore AD80, a multikinase inhibitor, as a drug option for CRC, with evaluation of the PI3K/AKT/mTOR and MAPK (ERK1/2) status of CRC cells' panel and the cytotoxicity of AD80 in those cells, as well as in normal colon cells. Main methods: Cellular and molecular mechanisms, such as clonogenicity, cell cycle, morphology, protein and mRNA expression, were investigated in CRC cells after AD80 exposure. Key findings: Results show that PI3K/AKT/mTOR and MAPK signaling pathways are upregulated in CRC cellular models, with increased phosphorylation of mTOR, P70S6K, S6RP, 4EBP1, and ERK1/2. Hence, AD80 selectively reduces cell viability of CRC cells. Therefore, the antitumor mechanisms of AD80, such as clonogenicity inhibition (reduction of colony number and size), G2/M arrest (increased G2/M population, and CDKN1B mRNA expression), DNA damage (increased H2AX and ERK1/2 phosphorylation, and CDKN1A and GADD45A mRNA expression), apoptosis (increased PARP1 cleavage, and BAX, PMAIP1, BBC3 mRNA expression) and inhibition of S6RP phosphorylation were validated in CRC model. Significance: Our findings reinforce kinases as promising cancer therapeutic targets for the treatment of colorectal cancer, suggesting AD80 as a drug candidate.
AD80, a multikinase inhibitor, exhibits antineoplastic effects in acute leukemia cellular models targeting the PI3K/STMN1 axis
Invest New Drugs 2021 Aug;39(4):1139-1149.PMID:33475938DOI:10.1007/s10637-021-01066-w.
Despite the great advances in the understanding of the molecular basis of acute leukemia, very little of this knowledge has been translated into new therapies. Stathmin 1 (STMN1), a phosphoprotein that regulates microtubules dynamics, is highly expressed in acute leukemia cells and promotes cell cycle progression and proliferation. GDP366 has been described as a STMN1 and survivin inhibitor in solid tumors. This study identified structural GDP366 analogs and the cellular and molecular mechanisms underlying their suppressive effects on acute leukemia cellular models. STMN1 mRNA levels were higher in AML and ALL patients, independent of risk stratification (all p < 0.001). Cheminformatics analysis identified three structural GDP366 analogs, with AD80 more potent and effective than GSK2606414 and GW768505A. In acute leukemia cells, GDP366 and AD80 reduced cell viability and autonomous clonal growth in a dose- and/or time-dependent manner (p < 0.05) and induced apoptosis and cell cycle arrest (p < 0.05). At the molecular level, GDP366 and AD80 reduced Ki-67 (a proliferation marker) expression and S6 ribosomal protein (a PI3K/AKT/mTOR effector) phosphorylation, and induced PARP1 (an apoptosis marker) cleavage and γH2AX (a DNA damage marker) expression. GDP366 induced STMN1 phosphorylation and survivin expression, while AD80 reduced survivin and STMN1 expression. GDP366 and AD80 modulated 18 of the 84 cytoskeleton regulators-related genes. These results indicated that GDP366 and AD80 reduced the PI3K/STMN1 axis and had cytotoxic effects in acute leukemia cellular models. Our findings further highlight STMN1-mediated signaling as a putative anticancer target for acute leukemia.
Pharmacologic Targeting of S6K1 in PTEN-Deficient Neoplasia
Cell Rep 2017 Feb 28;18(9):2088-2095.PMID:28249155DOI:10.1016/j.celrep.2017.02.022.
Genetic S6K1 inactivation can induce apoptosis in PTEN-deficient cells. We analyzed the therapeutic potential of S6K1 inhibitors in PTEN-deficient T cell leukemia and glioblastoma. Results revealed that the S6K1 inhibitor LY-2779964 was relatively ineffective as a single agent, while S6K1-targeting AD80 induced cytotoxicity selectively in PTEN-deficient cells. In vivo, AD80 rescued 50% of mice transplanted with PTEN-deficient leukemia cells. Cells surviving LY-2779964 treatment exhibited inhibitor-induced S6K1 phosphorylation due to increased mTOR-S6K1 co-association, which primed the rapid recovery of S6K1 signaling. In contrast, AD80 avoided S6K1 phosphorylation and mTOR co-association, resulting in durable suppression of S6K1-induced signaling and protein synthesis. Kinome analysis revealed that AD80 coordinately inhibits S6K1 together with the TAM family tyrosine kinase AXL. TAM suppression by BMS-777607 or genetic knockdown potentiated cytotoxic responses to LY-2779964 in PTEN-deficient glioblastoma cells. These results reveal that combination targeting of S6K1 and TAMs is a potential strategy for treatment of PTEN-deficient malignancy.
Phenotype-Based Screens with Conformation-Specific Inhibitors Reveal p38 Gamma and Delta as Targets for HCC Polypharmacology
Mol Cancer Ther 2019 Sep;18(9):1506-1519.PMID:31213506DOI:10.1158/1535-7163.MCT-18-0571.
The approved kinase inhibitors for hepatocellular carcinoma (HCC) are not matched to specific mutations within tumors. This has presented a daunting challenge; without a clear target or mechanism, no straightforward path has existed to guide the development of improved therapies for HCC. Here, we combine phenotypic screens with a class of conformation-specific kinase inhibitors termed type II to identify a multikinase inhibitor, AD80, with antitumoral activity across a variety of HCC preclinical models, including mouse xenografts. Mass spectrometry profiling found a number of kinases as putative targets for AD80, including several receptor and cytoplasmic protein kinases. Among these, we found p38 gamma and delta as direct targets of AD80. Notably, a closely related analog of AD80 lacking p38δ/γ activity, but retaining several other off-target kinases, lost significant activity in several HCC models. Moreover, forced and sustained MKK6 → p38→ATF2 signaling led to a significant reduction of AD80 activity within HCC cell lines. Together with HCC survival data in The Cancer Genome Atlas and RNA-seq analysis, we suggest p38 delta and gamma as therapeutic targets in HCC and an "AD80 inhibition signature" as identifying those patients with best clinical outcomes.
Multi-kinase targeted therapy as a promising treatment strategy for ovarian tumors expressing sfRon receptor
Genes Cancer 2020 Jul 22;11(3-4):106-121.PMID:33488949DOI:10.18632/genesandcancer.205.
The sfRon kinase is an important therapeutic target in ovarian cancer that contributes to prominent tumor growth and disease progression. We reasoned that a multi-kinase inhibition of sfRon pathway might be an effective strategy to achieve a sustained anti-tumor response, while simultaneously preventing treatment resistance. We performed a detailed dissection of sfRon signaling in vitro and demonstrated that S6K1 is a key component of a multi-kinase targeting strategy in sfRon expressing ovarian tumors. We selected AD80 compound that targets several kinases within sfRon pathway including AKT and S6K1, and compared its efficacy with inhibitors that selectively target either sfRon or PI3 kinase. Using human ovarian xenografts and clinically relevant patient-derived xenografts (PDXs), we demonstrated that in vivo treatment with single agent AD80 shows superior efficacy to a standard-care chemotherapy (cisplatin/paclitaxel), or to the direct inhibition of sfRon kinase by BMS777607. Our findings indicate that ovarian tumors expressing sfRon are most effectively treated with multi-kinase inhibitors simultaneously targeting AKT and S6K1, such as AD80, which results in long-term anti-tumor response and prevents metastasis development.
