For the choroid plexus, the extent of Gf enhancement served as a diagnostic criterion to distinguish between diseased and healthy control mice with a sensitivity of 89% and a specificity of 80%. Furthermore, Gf improved the detection of lesions, being particularly sensitive to optic neuritis. In correlated histological slices, Gf initially ...
Neurite outgrowth and neuronal differentiation play a crucial role in the development of the nervous system. subtype (ER) agonist high-throughput drug screening process (Chen et al. 2006). Brann et al. (2007) reported that estrogen receptor modulators may have multi-targeting neuroprotection. Although several studies defined numerous pharmacological effects of liquiritin and its derivatives, neuroprotection and neurotrophic effects in neuronal cells has not been investigated in detail. Thus, we investigated the Sirolimus small molecule kinase inhibitor effects of liquiritin flavonoids in outgrowth of Personal computer12 cells. We noticed significantly enhanced NGF dependent neurite outgrowth in Personal computer12 cells after liquiritin exposure.

The Ras/MEK/ERK and PI3K/Akt/mTor pathways play a central role in the regulation of normal cell growth, division and differentiation. Dysregulation of these signaling pathways driven by oncogenic mutations/activation leading to elevated kinase activity has been demonstrated in many human cancers. Strong evidence suggests the existence of a feedback loop with crosstalk between these two signaling cascades leading to redundancy in survival pathways. Consequently, monotherapy targeting a single cascade may be insufficient to induce tumor cell death due to drug resistance mechanisms. Initial biological results are presented from a series of novel small molecule kinase inhibitors specifically designed to simultaneously target both MEK1 and PI3K. Structural analogs of the ATP-competitive PI3K inhibitor ZSTK474 and the ATP-noncompetitive class of MEK inhibitors PD0325901, respectively, were covalently combined to provide single compound dual inhibitors. Inhibitors showed potent MEK1 inhibition (0.015 , ...
ROS1 is a receptor tyrosine kinase (encoded by the gene ROS1) with structural similarity to the anaplastic lymphoma kinase (ALK) protein; it is encoded by the c-ros oncogene and was first identified in 1986.[7][8][9][10] The exact role of the ROS1 protein in normal development, as well as its normal physiologic ligand, have not been defined.[8] Nonetheless, as gene rearrangement events involving ROS1 have been described in lung and other cancers, and since such tumors have been found to be remarkably responsive to small molecule tyrosine kinase inhibitors, interest in identifying ROS1 rearrangements as a therapeutic target in cancer has been increasing.[7][11] Recently, the small molecule tyrosine kinase inhibitor, crizotinib, was approved for the treatment of patients with metastatic NSCLC whose tumors are ROS1 -positive.[12]. Gene rearrangements involving the ROS1 gene were first detected in glioblastoma tumors and cell lines.[13][14] In 2007 a ROS1 rearrangement was identified in a cell line ...
For glioblastoma (GBM) treatments to be effective in vivo, understanding the effects of the tumor microenvironment is imperative. In traditional cell culture conditions, glucose concentrations do not model physiologic levels, nor the diminished concentrations found in tumor niches. We therefore sought to profile the differences in kinase activity in GBM cells cultured in restricted glucose to identify pathways that could be targeted with small molecule inhibitors. Using the PamStation12 platform, we examined the ability of GBM lysates from cells cultured in standard or low glucose conditions to phosphorylate 144 tyrosine and 144 serine/threonine peptides that correspond to known protein phosphorylation sites. Potential kinase targets were identified and validated using small molecule kinase inhibitors in GBM spheroid cultures. Using results from two GBM patient-derived xenografts, we determined common changes to peptides derived from Phospholipase C, Gamma 1 (PLCG1) and Raf-1. Using PLC and Raf

It is used in treating chronic myelogenous leukemia (CML), gastrointestinal stromal tumors (GISTs) and a number of other malignancies. It is the first member of a new class of agents that act by inhibiting particular tyrosine kinase enzymes, instead of non-specifically inhibiting rapidly dividing cells ...
ENMD-2076 is a novel orally-active, small molecule kinase inhibitor with a mechanism of action involving several pathways key to tumor growth and survival: angiogenesis, proliferation and the cell cycle. ENMD-2076 has selective activity against the mitotic kinase Aurora A, as well as kinases involved in angiogenesis (VEGFRs, FGFRs). ENMD-2076 inhibited the growth in vitro of a wide range of human solid tumor and hematopoietic cancer cell lines with IC50 values ranging from 0.025-0.7 µM. ENMD-2076 was also shown to induce regression or complete inhibition of tumor growth in vivo, at well-tolerated doses in tumor xenograft models derived from breast, colon, melanoma, leukemia and multiple myeloma cell lines. Pharmacodynamic experiments in vivo demonstrated that in addition to inhibiting Aurora A, single doses of ENMD-2076 had sustained inhibitory effects on the activation of Flt3 as well as the angiogenic tyrosine kinases VEGFR2/KDR and FGFR1 and 2. ENMD-2076 was shown to prevent the formation of ...
The paradoxical role of reactive oxygen species in cell death versus cell survival establishes a delicate balance between chemotherapy efficacy and management of detrimental unwanted effects. cell loss of life in response to both Taxol and cisplatin.

Steroid hormones take action in the central and peripheral nervous systems to regulate a variety of functions, including development, cell proliferation, cognition and behavior. al., 1994). PR-A and PR-B appear to have distinct functions in reproductive behavior and physiology (Mulac-Jericevic and Conneely, 2004; Mani et al., 2006). In the classic genomic mechanism of steroid action (Number 1), steroid receptors in the absence of hormone are complexed with several chaperone molecules, including heat shock protein (hsp)90 (Pratt et al., 2004). Upon binding hormone, steroid receptors undergo a conformational switch that allow receptors to dimerize (DeMarzo et al., 1991). These triggered receptor dimers bind directly to specific steroid response elements (SREs) and SRE-like sequences in the promoter regions of target genes (Mangelsdorf et al., 1995). Binding of receptors to DNA raises or decreases gene transcription by altering the pace of recruitment of general transcription factors and ...
The anti-epidermal growth factor receptor (EGFR) antibodies cetuximab and panitumumab are used to treat RAS wild-type colorectal cancers (CRCs), but their efficacy is limited by the emergence of acquired drug resistance. After EGFR blockade, about 20% of CRCs develop mutations in the EGFR extracellular domain (ECD) that impair antibody binding and are associated with clinical relapse. We hypothesized that EGFR ECD-resistant variants could be targeted by the recently developed oligoclonal antibody MM-151 that binds multiple regions of the EGFR ECD. MM-151 inhibits EGFR signaling and cell growth in preclinical models, including patient-derived cells carrying mutant EGFR. Upon MM-151 treatment, EGFR ECD mutations decline in circulating cell-free tumor DNA (ctDNA) of CRC patients who previously developed resistance to EGFR blockade. These data provide molecular rationale for the clinical use of MM-151 in patients who become resistant to cetuximab or panitumumab as a result of EGFR ECD mutations. ...
Secondary mutations in the tyrosine kinase domain (TKD) remain the most commonly encountered cause of acquired clinical resistance to small-molecule tyrosine kinase inhibitors (TKI) in human cancer (1-4). Recent pharmaceutical efforts have focused on the development of type II kinase inhibitors, which bind to a relatively nonconserved inactive kinase conformation and exploit an allosteric site adjacent to the ATP-binding pocket as a potential means to increase kinase selectivity, although recent data suggest such efforts may be misguided (5). Commonly, kinase domain (KD) mutations effect resistance to type II inhibitors via two mechanisms: (i) substitution of amino acid positions directly involved in binding inhibitor, or (ii) mutation of residues that stabilize the inactive kinase conformation required for binding (6). Type I inhibitors, which bind to the more conserved active kinase conformation, are typically vulnerable only to mutations at inhibitor contact residues and therefore may be ...
Seattle Genetics recently released data suggesting that tucatinib, when combined with trastuzumab (Herceptin; Genentech) and capecitabine, may effectively treat patients with locally advanced inoperable or metastatic HER2-positive breast cancer who have received prior therapies. In a phase II trial, the drug extended overall survival (OS) and progression-free survival (PFS) compared with trastuzumab and capecitabine alone and provided a PFS benefit in patients with brain metastases.. Patients with HER2-positive breast cancer usually receive trastuzumab and pertuzumab (Perjeta; Genentech) plus a taxane-based chemotherapy first, followed by ado-trastuzumab emtansine (T-DM1, Kadcyla; Genentech) for progressive disease. Once the disease metastasizes, however, effective therapies are lacking, especially for the 30% to 50% of patients who also develop brain lesions.. Highly selective for HER2, tucatinib is a small-molecule tyrosine kinase inhibitor (TKI). In a phase Ib trial, tucatinib plus ...

Based on genetic studies that establish the role of spleen tyrosine kinase (Syk) in immune function, inhibitors of this kinase are being investigated as therapeutic agents for inflammatory diseases. Because genetic studies eliminate both adapter functions and kinase activity of Syk, it is difficult to delineate the effect of kinase inhibition alone as would be the goal with small-molecule kinase inhibitors. We tested the hypothesis that specific pharmacological inhibition of Syk activity retains the immunomodulatory potential of Syk genetic deficiency. We report here on the discovery of (4-(3-(2H-1,2,3-triazol-2-yl)phenylamino)-2-((1R,2S)-2-aminocyclohexylamino) pyrimidine-5-carboxamide acetate (P505-15), a highly specific and potent inhibitor of purified Syk (IC50 1-2 nM). In human whole blood, P505-15 potently inhibited B cell antigen receptor-mediated B cell signaling and activation (IC50 0.27 and 0.28 μM, respectively) and Fcε receptor 1-mediated basophil degranulation (IC50 0.15 μM). ...
In a phase I trial, the combination of the BCR-ABL1 inhibitor asciminib and the small-molecule kinase inhibitor imatinib showed preliminary efficacy, safety, and tolerability in patients with chronic myeloid leukemia (CML) resistant to or intolerant of treatment with two or more prior tyrosine kinase inhibitors. These data were presented by Talpaz et al at the 2019 Society of Hematologic Oncology (SOHO) Annual Meeting and published in Clinical Lymphoma, Myeloma & Leukemia.. Methods. A total of 25 patients with chronic phase CML were enrolled in the trial; 15 of the 25 had been treated with more than two prior tyrosine kinase inhibitors and 17 of the 25 had previously been treated with imatinib.

Back ground: Insulin-like growth factor-1 receptor (IGF1R) activity is upregulated in a variety of human cancers and IGF1R signaling has been implicated as a mechanism of resistance to various cancer therapies, including radiotherapy, cytotoxic chemotherapy, and targeted molecular therapy. We have demonstrated that IGF1R activation can induce resistance to targeted therapy of head and neck squamous cell carcinomas (HNSCCs) using epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). Targeting the IGF1R by selective small molecule kinase inhibition may thus hold promise as an adjuvant treatment for HNSCC.. Aims: (1) To assess the anti-tumor effects of two IGF1R/insulin receptor TKIs, BMS-754807 and OSI-906, in multiple HNSCC cell lines in vitro. (2) To evaluate the effect of combined IGF1R and EGFR inhibition in HNSCC cell lines in vitro.. Methods: The effect of IGF1R inhibition on cell proliferation, viability, survival, and apoptosis was assessed using alamarBlue, trypan ...
Exquisitely selective turn-on probes of kinase activation and localization Protein kinase-mediated phosphorylation is a vital posttranslational modification in eukaryotic cell signaling. Efforts to understand these complex signaling pathways have been hampered by a lack of selective kinase inhibitors. Nearly all known kinase inhibitors bind in the highly conserved ATP pocket. Although potency is easy to obtain within the ATP-pocket, selectivity is difficult to obtain due to the similar nature of this binding pocket across the kinome. Non-ATP-competitive inhibitors usually possess higher degrees of selectivity than their ATP-competitive counterparts, however, they generally suffer from a lack of potency. In contrast, both high potency and high selectivity can be obtained with bisubstrate inhibitors. Bisubstrate kinase inhibitors interact with both binding pockets; interactions within the ATP pocket provide potency while interactions within the substrate site provide selectivity. Here, we propose ...
The test is intended to be used to identify patients with advanced NSCLC whose tumors harbor mutations in exons 18, 19, 20 and 21 of the EGFR gene, and to select patients for treatment with small molecule tyrosine kinase inhibitors (TKIs) that target EGFR, and where the sample tumour content is low (i.e. less 30%). Sanger sequencing is currently still the method of choice for samples with tumour content of 30% or higher. ...
Most potent protein kinase inhibitors act by competing with ATP to block the phosphotransferase activity of their targets. families encoded by the human genome and major constituents of most intracellular signaling cascades (Manning et al., 2002b),(Manning et al., 2002a). These signaling enzymes play important functions in countless cellular pathways, and the proper regulation of their activity is essential for normal cellular behavior. Aberrant kinase function is usually linked to numerous diseases, and a number of kinases are promising targets for the development of small molecule-based therapies (Cohen and Alessi, 2013). Currently, Ehk1-L a majority of potent and selective kinase inhibitors block phosphotransferase activity by competing with ATP (Zhang et al., 2009). While many of these inhibitors are able to interact with the ATP-binding clefts of kinases in an active conformation, a subset of inhibitors are conformation-selective, in that they only bind to their targets if conserved ...

The advent of Gleevec® (imatinib) less than 10 years ago was a landmark for utilizing small molecule compounds as kinase inhibitor drugs (1-3). This type of drug is usually directed against one specific kinase whose malfunctioning plays a key role in the given disease. Generally these drugs are thought to be selective, easy to modify, and effective. As the molecular principles of various diseases are better understood, kinase inhibitors are being developed in various fields with cancer remaining the predominant one (4). Kinase inhibitor compounds constitute about 30% of all drug development programs in the pharmaceutical industry (5).. Kinase inhibitor drugs are typically developed with a targeted and rational strategy, often focusing on a kinase known to be involved in the etiology of a disease. Large libraries of chemical compounds, for example ATP analogs, are screened in vitro against the activity of this kinase, and their effects on a panel of manually selected kinases with similar ...

Treatment with epidermal development aspect receptor tyrosine kinase inhibitors (EGFR-TKIs), such as for example gefitinib and erlotinib, offers achieved great clinical response prices in sufferers with nonCsmall cell lung malignancies (NSCLCs). without them [1 of 7 (14%) vs 9 of 15 (60%); chi-squared check, p ?=? 0.0449], indicating the harmful correlation between your immune system responses towards the EGFR-T790M-derived epitopes and the current presence of EGFR-T790M mutation in NSCLC sufferers. This finding may be explained with the hypothesis that immune system responses towards the mutated neo-antigens produced Docetaxel (Taxotere) from T790M might avoid the introduction of tumor cell variations using the T790M Docetaxel (Taxotere) level of resistance mutation in NSCLC sufferers during EGFR-TKI treatment. Jointly, our results claim that the discovered T cell epitopes may provide a book immunotherapeutic strategy for avoidance and/or treatment of EGFR-TKI level of resistance with the ...

DESCRIPTION (provided by applicant): Hematologic toxicity is a principal cause of morbidity and mortality after exposure to ionizing radiation (IR). G-Zero Therapeutics, with operations in the Research Triangle Park, North Carolina, has developed a novel approach to mitigating the hematologic toxicity of total body irradiation (TBI). This approach relies on the administration of novel, orally bioavailable small molecule kinase inhibitors around the time of exposure to TBI. These compounds in turn induce pharmacological quiescence (PQ) of the early hematopoietic stem and progenitor cells (HSPC) through the inhibition of cyclin dependent kinases (CDKs) which govern the G1-S transition of the cell cycle. As quiescent cells are resistant to IR, PQ enhances the per cell survival of HSPC by augmenting the repair of DNA damage post-TBI. This enhanced survival of HSPC in turn translates into markedly reduced acute hematologic toxicity. G-Zero has shown in mice that the PQ approach can significantly ...

TUNEL staining and MTT assays also showed that 4-PBA and ryanodine obviously alleviated 6-OHDA-induced cell apoptosis and devitalization. Interestingly, a IP3Rs blocker experienced little effect on the above 6-OHDA-induced neurotoxicity in DA neurons. In conclusion, our findings provide evidence of the different tasks of IP3Rs and RyRs in the rules of endogenous Ca2+ homeostasis, neuronal excitability, and viability in DA neurons, and suggest a potential therapeutic strategy for PD by inhibiting the RyRs Ca2+ channels in the ER. model system for study SNc DA neurons (Son et al., 1999). We also investigated cellular excitability in a 6-OHDA-induced PD model in midbrain slices. Our data demonstrated the ...
Olfactory ensheathing cells (OECs) are a type of specialized glial cell currently considered as having a double function in the nervous system: one regenerative, and another immune. OEC cultures resulted in continuous NF-B activation. The IFN-induced increase of iNOS manifestation was reversed in infected OECs. OECs are susceptible to infection, which can suppress their cytotoxic mechanisms in order to survive. We suggest that, in contrast to microglia, OECs might serve as safe focuses on for pneumococci, providing a more stable environment for evasion of the immune system. Olfactory ensheathing cells (OECs) are a type of specialized glial cell that accompany and ensheath the primary olfactory axons through the olfactory pathway, from your olfactory epithelium to Natamycin small molecule kinase inhibitor the olfactory tract. OECs are crucial for olfactory axonal assistance and outgrowth inside the developing and adult olfactory program1,2. This real estate of OECs makes them a superb candidate ...
TY - CHAP. T1 - Targeted Therapies in Chronic Myeloid Leukemia. AU - Jabbour, Elias. AU - Cortes, Jorge. PY - 2015/10/30. Y1 - 2015/10/30. N2 - Until 2000, therapy for chronic myeloid leukemia (CML) was limited to nonspecific agents such as busulfan, hydroxyurea, and interferon-alpha (IFN-a). The landscape changed dramatically with the development of small-molecule tyrosine kinase inhibitors (TKIs) that was shown to potently interfere with the interaction between the BCR-ABL protein and adenosine triphosphate (ATP), blocking cellular proliferation of the malignant clone. Three TKIs are commercially available for the front-line treatment of CML: imatinib, dasatinib, and nilotinib. With the updates of the DASISION and ENESTnd trials, the question often arises as to the optimal choice for front-line management of CP-CML. Based on attainment of faster and higher rates of complete cytogenetic response (CCyR), major molecular response (MMR), and complete molecular response (CMR), and a trend for lower ...
Relapse occurred in 7 (44%) of the 16 patients who stopped tyrosine kinase inhibitor treatment at the time of complete remission, 4 (33%) of the 12 who stopped treatment after additional cycles, and 1 (13%) of the 8 who were still receiving a tyrosine kinase inhibitor. The median time from complete remission to relapse was 7.9 months (range, 3-32 months). Relapse occurred at a previously involved metastatic site in 5 of 12 patients with relapse. Thus, of the 28 patients who stopped tyrosine kinase inhibitor treatment, 17 (61%) remained in complete remission after a median follow-up of 8.5 months (range, 0.3-39.1 months). Tyrosine Kinase Inhibitor Plus Local Treatment. A total of 28 patients (44%) achieved complete remission with a tyrosine kinase inhibitor and local therapy (Fig. 2), consisting of surgery in 22 (79%), radiofrequency ablation in 2 (7%), and radiation therapy in 4 (14%). Most patients received local therapy for pulmonary metastases. The median time from starting tyrosine kinase ...
AZD-0424 is an orally bioavailable small molecule tyrosine kinase inhibitor that targets both Abl and Src kinases with potential antineoplastic activity. Upon oral administration, AZD0424 selectively inhibits both Src and Abl kinase activity which may result in the inhibition of tumor growth in susceptible tumor cells. Src and Abl kinases are upregulated in certain tumor cells and play important roles in tumor cell proliferation and metastasis. Check for active clinical trials or closed clinical trials using this agent.
The transforming growth factor α (TGFα) epidermal growth factor receptor (EGFR) autocrine pathway plays a key role in the development and progression of human epithelial cancers (1). Overexpression of TGFα and/or EGFR has been detected in the majority of human carcinomas, has been associated with resistance to cytotoxic drugs and to hormone therapy, and is generally an indicator of poor prognosis (1). For these reasons, the blockade of the EGFR-driven autocrine pathway has been proposed as a target for anticancer therapy (2). Several pharmacologic approaches have been developed for blocking EGFR. The two most successful approaches for the treatment of cancer patients have been thus far the anti-EGFR-blocking monoclonal antibodies (MAb), such as Cetuximab, and the selective EGFR small molecule tyrosine kinase inhibitors (TKI), such as Gefitinib and Erlotinib (3-5).. Tumor angiogenesis is the process leading to the formation of blood vessels within a tumor and plays a key role in cancer cell ...
HER2/ERBB2-overexpressing breast cancers targeted effectively by the small-molecule kinase inhibitor lapatinib frequently acquire resistance to this drug. In this study, we employed explorative mass spectrometry to profile proteome, kinome, and phosphoproteome changes in an established model of lapatinib resistance to systematically investigate initial inhibitor response and subsequent reprogramming in resistance. The resulting dataset, which collectively contains quantitative data for ,7,800 proteins, ,300 protein kinases, and ,15,000 phosphopeptides, enabled deep insight into signaling recovery and molecular reprogramming upon resistance. Our data-driven approach confirmed previously described mechanisms of resistance (e.g., AXL overexpression and PIK3 reactivation), revealed novel pharmacologically actionable targets, and confirmed the expectation of significant heterogeneity in molecular resistance drivers inducing distinct phenotypic changes. Furthermore, our approach identified an ...
We have developed a deep generative model, generative tensorial reinforcement learning (GENTRL), for de novo small-molecule design. GENTRL optimizes synthetic feasibility, novelty, and biological activity. We used GENTRL to discover potent inhibitors of discoidin domain receptor 1 (DDR1), a kinase target implicated in fibrosis and other diseases, in 21 days. Four compounds were active in biochemical assays, and two were validated in cell-based assays. One lead candidate was tested and demonstrated favorable pharmacokinetics in mice. A machine learning model allows the identification of new small-molecule kinase inhibitors in days.
By Kevin E. Noonan -- Lest anyone think that Myriad Genetics is the only patentee asserting rights in patents having claims to isolated DNA molecules or other biological molecules, St. Judes Childrens Research Hospital, Inc. has sued Novartis Pharmaceuticals Corp. in the Federal District Court, Western District of Tennessee for infringing U.S. Patent Nos. 5,529,925; 5,770,421; and 6,696,548 (see Court Report, October 20, 2013). The grounds for St. Judes infringement allegations are activities by Novartis to research, develop, and evaluate small molecule tyrosine kinase inhibitors, including, but not limited to, LDK378, some of that research having taken place in Memphis,...
Knockdown or genetic deletion of PTEN promotes substantial axon regeneration in an mTOR-dependent manner, both in the optic nerve and in the CST (Park et al., 2008, 2010; K. Liu et al., 2010; Zukor et al., 2013; Du et al., 2015). It has therefore been suggested that the activity of S6K1, an effector of mTOR, is required for regeneration in this paradigm (Yang et al., 2014). Nevertheless, experimental results on this point are conflicting (Hubert et al., 2014; Yang et al., 2014). In our study, we found that decreased phosphorylation of S6K1s substrate, S6, strongly correlates with promotion of neurite outgrowth in primary neurons treated with a variety of small-molecule kinase inhibitors, and that pharmacological inhibition of S6K1 promotes neurite outgrowth in primary neurons. Activation of PI3K/mTOR signaling, in response to the release of S6K1-mediated negative feedback on this pathway, may be driving the induction of neurite outgrowth. Consistent with this, we observed that inhibiting S6K1 ...
Enterotoxigenic (ETEC) diarrheal disease is a worldwide problem that may be addressed by transcutaneous delivery of a vaccine. also be achieved by intravenous injection of the immune sera. Finally, a malaria vaccine antigen, merzoite surface protein 142 administered with CT as the adjuvant, induced both merzoite surface protein antibodies and T-cell responses while conferring protective antitoxin immunity, suggesting that both antiparasitic activity and antidiarrheal activity can be obtained with a single vaccine formulation. Overall, our results demonstrate that relevant colonization factor and antitoxin immunity can be induced by TCI and suggest that an ETEC travelers diarrhea vaccine could be delivered by using a patch. Enterotoxigenic (ETEC) diarrhea is a worldwide problem that is responsible for 400,000 to 800,000 deaths per year (20). It is a primary cause of morbidity and mortality in children less than 5 years old (3, 39) and is a significant cause of Linagliptin small molecule kinase ...

The cortistatins are a group of steroidal alkaloids first isolated in 2006 from the marine sponge Corticium simplex. The cortistatins were first discovered in a search for naturally occurring compounds that inhibit proliferation of human umbilical vein endothelial cells (HUVECs), with cortistatin A being the most potent compound in the class. The Shair group at Harvard along with collaborators have shown that cortistatin A is a highly potent and selective inhibitor of CDK8 and CDK19, the kinases that associate with Mediator complex. Out of 386 kinases evaluated, cortistatin A only inhibited CDK8 and CDK19, revealing that it is among the most selective kinase inhibitors. It was also shown that cortistatin A potently inhibits growth of acute myeloid leukemia cells and AML in two in vivo mouse models. Identification of dominant drug-resistant alleles of CDK8 and CDK19 demonstrate that these kinases mediate the activity of cortistatin A in AML cells. Thus, inhibition of CDK8 and CDK19 is a new ...
Background Several little receptor tyrosine kinase inhibitors (RTKI) have entered medical cancer trials alone and in conjunction with radiotherapy or chemotherapy. cells had been employed. LEADS TO fibroblasts, rays markedly triggered PDGF signaling as recognized by improved PDGFR phosphorylation that was potently inhibited by SU9518. In fibroblast clonogenic assay, SU9518 decreased PDGF activated fibroblast success by 57%. Also, SU9518 potently inhibited fibroblast and endothelial cell proliferation. In the co-culture model, rays of endothelial cells and fibroblast cells considerably activated proliferation of non irradiated fibroblasts and vice versa. Significantly, the RTK inhibitor considerably inhibited this paracrine buy 838818-26-1 radiation-induced fibroblast and endothelial cell activation. Summary Radiation-induced autocrine and paracrine PDGF signaling takes on an important part in fibroblast and endothelial cell proliferation. SU9518, a PDGFR tyrosine kinase inhibitor, decreases ...
TY - JOUR. T1 - An EGFR signature predicts cell line and patient sensitivity to multiple tyrosine kinase inhibitors. AU - Cheng, Chao. AU - Zhao, Yanding. AU - Schaafsma, Evelien. AU - Weng, Yi Lan. AU - Amos, Christopher. PY - 2020/11/1. Y1 - 2020/11/1. N2 - EGFR is an oncogene with a high frequency of activating mutations in nonsmall cell lung cancer (NSCLC). EGFR inhibitors have been FDA-approved for NSCLC and have shown efficacy in patients with certain EGFR mutations. However, only 9% to 26% of these patients achieve objective responses. In our study, we developed an EGFR gene signature based on The Cancer Genome Atlas (TCGA) RNA-seq data of lung adenocarcinoma (LUAD) to direct the preselection of patients for more effective EGFR-targeted therapy. This signature infers baseline EGFR signaling pathway activity (denoted as EGFR score) in tumor samples, which is associated with tumor sensitivity to EGFR inhibitors and other tyrosine kinase inhibitors (TKIs). EGFR score predicted sensitivity of ...
Background: Tyrosine kinase inhibitors (TKIs) have increased survival dramatically for patients with chronic myeloid leukemia (CML), but continuous administration of these drugs may elicit long-term toxicity. Objective: To investigate the incidence of vascular events in patients with CML treated with first-and second-generation TKIs. Design: Retrospective cohort study using nationwide population-based registries. Setting: Sweden. Patients: All patients diagnosed with chronic-phase CML in Sweden from 2002 to 2012 and treated with a TKI, and 5 age- and sex-matched control individuals per patient. Measurements: Relative risks, expressed as incidence rate ratios comparing patients with control individuals, were calculated. Events per 1000 person-years were assessed in interdrug comparisons. Results: 896 patients, 94.4% with documented TKI treatment, were followed for a median of 4.2 years. There were 54 arterial and 20 venous events in the CML cohort, corresponding to relative risks of 1.5 (95% CI, ...
Orally bioavailable compounds that target key intracellular signalling molecules are receiving increasing attention for the treatment of rheumatic diseases. The mitogen activated protein (MAP) kinases are especially attractive because they regulate both cytokine production and cytokine action. The MAP kinases are expressed and activated in rheumatoid arthritis (RA) synovium. Preclinical studies using MAP kinase inhibitors are very effective in animal models of arthritis, supporting their potential utility in human disease. Although the available data suggest a rationale for MAP kinase blockade, development of drugs has been hampered by toxicity and limited efficacy. Alternative strategies, such as targeting other kinases in the cascade or development of allosteric inhibitors have been proposed. These approaches might permit effective use of MAP kinase inhibitors for the treatment of rheumatic and immune-mediated diseases.. ...

Purpose : Protein kinases play an important role in several cell processes such as proliferation, transcription, and pathologic changes. Kinase inhibitors have thus been proposed for treatment against diseases including cancer. In ophthalmology, ROCK inhibitor has already been launched as an antiglaucoma drug in Japan. However, discovery of small molecule inhibitors for specific protein kinases is still challenging. This is because approximately 500 protein kinases exist and more than 2,000 other purine-binding proteins share similar ATP binding pockets of kinases. The purpose of this study was to develop an in silico method for identifying potential kinase inhibitors, and the anticancer drug axitinib was used as a representative kinase inhibitor. Methods : Sequences for 9 typical kinases were compared to VEGFR tyrosine kinase, the three amino acid sequences on the hinge region of each kinase were identified, and the surfaces of the ATP binding cavities in the kinases were analyzed in silico ...
Introduction: Kinase inhibitors have been hailed as a breakthrough in the treatment of cancer. Extensive research is now being devoted to the development of kinase inhibitors as a treatment for many nonmalignant diseases. However, the use of kinase inhibitors in both malignant and nonmalignant diseases is also associated with side effects and the development of resistance. It may be worthwhile to explore whether cell-specific delivery of kinase inhibitors improves therapeutic efficacy and reduces side effects.. Areas covered: This review aims to provide an overview of the preclinical studies performed to examine the specific targeting of kinase inhibitors in vitro and in vivo. It gives an introduction to kinase signaling pathways induced during disease, along with the possible problems associated with their inhibition. It also discusses the studies on specific delivery and shows that altering the specificity of kinase inhibitors by targeting methods improves their effectivity and safety.. Expert ...

Background: Tyrosine kinase inhibitor (TKI)-based therapy is a recommended treatment for patients with chronic myeloid leukemia (CML). However, a considerable group of CML patients do not respond well to the TKI therapy. Challenging to overcome this problem, we tried to discover molecular signatures in gene expression profiles to discriminate the responders and non-responders of TKI therapy. Methods: We collected three microarray datasets of CML patients having total 73 responders and 38 non-responders. Statistical analysis was performed to identify differentially expressed genes (DEGs) as gene signature candidates from integrated microarray datasets. The classification performance of these genes and further selected discriminator gene sets was tested by using random forest and iterative backward variable selection methods. Results: We identified a set of genes including CTBP2, NADK, AZU1, CTSH, FSTL1, and HDLBP showing the highest accuracy more than 69.44 % to classify TKI response in CML ...

Struc tural data of HsHDAC8 pointed out the purpose in the residue D101 in the two substrate and HDACi recognition, HsH DAC8D101A mutated enzyme was inactive on protein sub strates and binding efficiency to hydroxamate inhibitor was decreased.Provided that D101 is localized from the vicinity of T99 of TgHDAC3, these data further strengthen the hypoth esis of a direct inhibition of TgHDAC3 by FR235222 and therefore are steady with a function of T99 in the interactions with cy clopeptide inhibitors. T99A and T99I adjust amino acid polarity, its as a result tempting to speculate that polar inter actions on the rim of the lively web page assistance the binding to HDACis, as proposed by Vannini et al.We predict the binding efficiency of HDACis to TgHDAC3 will be diminished while in the T99A and T99I mutated versions of TgH DAC3.

UNC2250 is a potent and selective Mer Kinase inhibitor. When applied to live cells, UNC2250 inhibited steady-state phosphorylation of endogenous Mer with an IC50 of 9.8 nM and blocked ligand-stimulated activation of a chimeric EGFR-Mer protein. Treatment with UNC2250 also resulted in decreased colony-forming potential in rhabdoid and NSCLC tumor cells, thereby demonstrating functional antitumor activity. The results provide a rationale for further investigation of UNC2250 for therapeutic application in patients with cancer..
