实验参考方法

Cell experiment: [1]

Cell lines

T cells

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months.

Reaction Conditions

IC50: 3.9 μM for inhibiting DCs-stimulated T-cell proliferation 2.9 μM for inhibiting PHA-stimulated T-cell proliferation 4 days

Applications

Cells were stimulated with allogeneic mature DCs or PHA in the presence of imatinib mesylate. The drug inhibited T-cell proliferation as a function of concentration. The effects were significant at 0.5 μM imatinib mesylate for the cells stimulated by DCs and at 1.0 μM imatinib mesylate for the cells stimulated with PHA. The IC50 values for imatinib mesylate–inhibited T-cell proliferation stimulated by DCs and PHA were 3.9 μM and 2.9 μM, respectively.

Animal experiment: [2]

Animal models

Female C57BL/6 mice

Dosage form

Intraperitoneal injection, 25 or 50mg/kg/day

Applications

Administration of imatinib alone did not generate any changes in lung morphology. However, when imatinib was administered in bleomycin-treated mice, a reduction of fibrotic lesions in the subpleural areas of lung was observed at doses of 25 and 50 mg/kg/day. The quantitative histologic analysis demonstrated that the fibrotic score in mice treated with bleomycin and 50 mg/kg/day of imatinib was significantly lower than that treated with bleomycin alone. The collagen content of the lung was also significantly lower in mice treated with bleomycin and imatinib (50 mg/kg/day) as compared with those treated with bleomycin alone.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

Imatinib mesylate is a tyrosine kinase inhibitor IC50 value of 100 nM, 100 nM, 600 nM for v-Abl, c-kit, PDGFR, respectively [1].
Tyrosine kinase is an enzyme which is a subclass of protein kinase and plays an important role in transferring a phosphate group from ATP to a protein in cells. It is shown that tyrosine kinase plays a pivotal role in the management of disorders in which activation of c-Abl, PDGFR, or c-Kit signaling. Recently, the role of tyrosine kinases in the modulation of growth factor signaling are received more and more attention and gradually become an especial important target [2].
Imatinib Mesylate is a specific tyrosine kinase (abl, c-kit, and PDGFR) inhibitor and is reported to sensitize cells to radio- or chemo-therapy. When tested with Y-79 and WERI-RB-1 Rb cell lines, imatinib mesylate treatment decreased the cell proliferation and invasion with the concentration of 10 μM [3]. In osteoblast cells, administration of imatinib mesylate decreased osteoclast development via stimulating differentiation, inhibiting proliferation and survival [4].
In dog model with mast cell tumor, administration of imatinib mesylate at a dose of 10 mg/kg daily for 1-9 weeks reduced tumor growth via inhibiting tyrosine kinase [5].

Research Update

Imatinib Mesylate

Imatinib mesylate (Gleevec, Glivec [Novartis, Basel, Switzerland], formerly referred to as STI571 or CGP57148B) represents the paradigm of a new class of anticancer agents, so-called small molecules. They have a high selectivity against a specific molecular target known to be the cause for the establishment and maintenance of the malignant phenotype. Imatinib is a rationally designed oral signal transduction inhibitor that specifically targets several protein tyrosine kinases, Abl, Arg (Abl-related gene), the stem cell factor receptor (c-KIT), platelet-derived growth factor receptor (PDGF-R), and their oncogenic forms, most notably BCR-ABL. Imatinib has been shown to have remarkable clinical activity in patients with chronic myeloid leukemia (CML) and malignant gastrointestinal stroma tumors (GIST) leading to its approval for treatment of these diseases. Treatment with imatinib is generally well tolerated with a low incidence of severe side effects. The most common adverse events include mild to moderate edema, muscle cramps, diarrhea, nausea, skin rashes, and myelosuppression. Several mechanisms of resistance have been identified. Clonal evolution, amplification, or overexpression of BCR-ABL as well as mutations in the catalytic domain, P-loop, and other mutations have been demonstrated to play a role in primary and secondary resistance to imatinib, respectively. Understanding of the underlying mechanisms of resistance has led to the development of new second- and third-generation tyrosine kinase inhibitors (see chapters on dasatinib, nilotinib, bosutinib, and ponatinib).

Kinase drug discovery 20 years after imatinib: progress and future directions

Protein kinases regulate nearly all aspects of cell life, and alterations in their expression, or mutations in their genes, cause cancer and other diseases. Here, we review the remarkable progress made over the past 20 years in improving the potency and specificity of small-molecule inhibitors of protein and lipid kinases, resulting in the approval of more than 70 new drugs since imatinib was approved in 2001. These compounds have had a significant impact on the way in which we now treat cancers and non-cancerous conditions. We discuss how the challenge of drug resistance to kinase inhibitors is being met and the future of kinase drug discovery.

The argument for using imatinib in CML

June 2018 was the 20th anniversary of the clinical use of the first tyrosine kinase inhibitor (TKI), imatinib, for chronic myeloid leukemia. Since then, the change in prognosis for patients with this disease is one of the major success stories of modern cancer medicine. The dilemmas that face physicians and patients are no longer only those concerned with delaying inevitable progression to the terminal blastic phase or selecting the individuals most likely to benefit from allogeneic stem-cell transplantation; rather, they are now focused also on the choice of TKI, the management of comorbidities and adverse effects, strategies to improve quality of life, and the appropriateness of a trial of therapy discontinuation. Interestingly, with 4 TKIs approved for frontline use, the choice of initial therapy continues to cause controversy, a situation made more complicated by the tantalizing prospect of treatment-free remission. In this manuscript, we will explore the factors influencing this decision and try to provide a pragmatic and clinically applicable solution.

Pharmacology and pharmacokinetics of imatinib in pediatric patients

The tyrosine kinase inhibitor (TKI) imatinib was rationally designed to target BCR-ABL1 which is constitutively activated in chronic myeloid leukemia (CML). Following the tremendous success in adults, imatinib also became licensed for treatment of CML in minors. The rarity of pediatric CML hampers the conduction of formal trials. Thus, imatinib is still the single TKI approved for CML treatment in childhood. Areas covered: This review attempts to provide an overview of the literature on pharmacology, pharmacokinetic, and pharmacogenetic of imatinib concerning pediatric CML treatment. Articles were identified through a PubMed search and by reviewing abstracts from relevant hematology congresses. Additional information was provided from the authors' libraries and expertise and from our own measurements of imatinib trough plasma levels in children. Pharmacokinetic variables (e.g. alpha 1-acid glycoprotein binding, drug-drug/food-drug interactions via cytochrome P450 3A4/5, cellular uptake mediated via OCT-1-influx variations and P-glycoprotein-mediated drug efflux) still await to be addressed in pediatric patients systematically. Expert commentary: TKI response rates vary among different individuals and pharmacokinetic variables all can influence CML treatment success. Adherence to imatinib intake may be the most prominent factor influencing treatment outcome in teenagers thus pointing towards the potential benefits of regular drug monitoring.
