概述
描述
Imatinib, sold under the brand names Gleevec and Glivec, is an oral targeted therapy medication used to treat various types of cancer. It is a small molecule inhibitor targeting multiple tyrosine kinases such as CSF1R, ABL, c-KIT, FLT3, and PDGFR-β . Imatinib is primarily used for chronic myelogenous leukemia (CML) and acute lymphocytic leukemia (ALL) that are Philadelphia chromosome-positive (Ph+), certain types of gastrointestinal stromal tumors (GIST), hypereosinophilic syndrome (HES), chronic eosinophilic leukemia (CEL), systemic mastocytosis, and myelodysplastic syndrome .
科学研究应用
Imatinib has revolutionized drug therapy for chronic myeloid leukemia (CML). It is used to treat CML, gastrointestinal stromal tumors (GISTs), and a number of other malignancies . In 2006, the FDA expanded its approved use to include dermatofibrosarcoma protuberans (DFSP), myelodysplastic/myeloproliferative diseases (MDS/MPD), and aggressive systemic mastocytosis (ASM) . Imatinib’s pharmacokinetic properties have been characterized, and it is well absorbed after oral administration, with a high protein binding rate .
作用机制
Target of Action:
Imatinib’s primary target is the BCR-ABL tyrosine kinase. This enzyme is constitutively active due to the Philadelphia chromosome abnormality found in chronic myeloid leukemia (CML). The BCR-ABL kinase drives uncontrolled cell proliferation and survival, contributing to the progression of CML .
Mode of Action:
Imatinib inhibits the BCR-ABL tyrosine kinase by binding to its active site. By doing so, it prevents the phosphorylation of downstream substrates, disrupting the signaling cascade that promotes cell growth and survival. Essentially, Imatinib puts the brakes on the abnormal protein’s activity, halting the division of cancer cells and inducing apoptosis (cell death) .
Biochemical Pathways:
The affected pathways include those related to cell cycle regulation, proliferation, and survival. By blocking BCR-ABL, Imatinib disrupts the ABL kinase’s overexpression seen in various tumors. This inhibition leads to downstream effects, ultimately curbing the growth of leukemic cells .
Pharmacokinetics:
Result of Action:
Imatinib’s action results in:
- Improved Survival : Enhanced overall survival in patients with Ph+ acute lymphoblastic leukemia and other indications .
Action Environment:
Environmental factors, such as drug interactions (e.g., CYP3A4 inhibitors), affect Imatinib’s efficacy and stability. Maintaining consistent drug levels is crucial for optimal therapeutic outcomes .
Remember, Imatinib’s success story exemplifies the power of targeted therapies tailored to individual cancer genetics. 🌿🧬 . If you have any more questions or need further details, feel free to ask!
生化分析
Biochemical Properties
Imatinib interacts with several enzymes and proteins. It is a tyrosine kinase inhibitor that targets multiple tyrosine kinases such as CSF1R, ABL, c-KIT, FLT3, and PDGFR-β . These interactions inhibit the tyrosine kinases, disrupting the signaling pathways they control, which can slow growth or result in programmed cell death of certain types of cancer cells .
Cellular Effects
Imatinib has significant effects on various types of cells and cellular processes. It influences cell function by impacting cell signaling pathways, gene expression, and cellular metabolism . For instance, it has been shown to switch from glycolysis to the tricarboxylic acid cycle, upregulate pentose phosphate pathway-associated oxidative pathways, and cause internal translocation of glucose transporters .
Molecular Mechanism
Imatinib exerts its effects at the molecular level primarily by inhibiting the Bcr-Abl tyrosine-kinase . This inhibition disrupts the signaling pathways controlled by these kinases, leading to slowed growth or programmed cell death of certain types of cancer cells .
Temporal Effects in Laboratory Settings
In laboratory settings, the effects of imatinib change over time. Imatinib is rapidly absorbed following oral administration, achieving pharmacologically relevant concentrations in the plasma, with a half-life of approximately 1.3 hours . It has been shown that continuous inhibition of BCR-ABL kinase activity is needed to achieve maximal antitumor effects .
Dosage Effects in Animal Models
The effects of imatinib vary with different dosages in animal models. For instance, once-daily intraperitoneal treatment using doses of imatinib from 2.5 to 50 mg/kg caused dose-dependent inhibition of tumor growth .
Metabolic Pathways
Imatinib is involved in several metabolic pathways. It is primarily metabolized by the CYP3A4 isoform of CYP450 . Other enzymes such as flavin-containing monooxygenase 3 (FMO3), and uridine 5’-diphospho-glucuronosyltransferase (UGT) also metabolize imatinib .
Transport and Distribution
Imatinib is transported and distributed within cells and tissues. It is the only tyrosine kinase inhibitor whose absorption depends on both influx (OCT1 and OATP1A2) and efflux (ABCB1 and ABCG2) transporters .
Subcellular Localization
Imatinib is sequestered in the lysosomes within cells . This lysosomal sequestration determines the intracellular levels of imatinib .
准备方法
The synthesis of Imatinib involves a classical convergent approach. The compound is assembled by coupling the amine and carboxylic acid precursors using N,N′-carbonyldiimidazole (CDI) as a condensing agent . The first synthesis of Imatinib, reported by Zimmermann, was based on the connection of two key intermediates: the aromatic amine and 4-[(4-methylpiperazin-1-yl)methyl]benzoyl chloride . Industrial production methods have been optimized to overcome certain problematic steps, save time and labor, and provide high yield and purity .
化学反应分析
Imatinib undergoes various types of chemical reactions, including oxidation, reduction, and substitution. Common reagents and conditions used in these reactions include hydrogen over Adam’s catalyst for reduction and CDI for condensation reactions . Major products formed from these reactions include various Imatinib analogues and impurities, which are characterized and confirmed using techniques such as IR, 1H-NMR, and Mass Spectrometry .
相似化合物的比较
Imatinib is compared with other tyrosine kinase inhibitors such as dasatinib, nilotinib, bosutinib, ponatinib, asciminib, and olverembatinib . These compounds are used to treat chronic myeloid leukemia (CML) and other malignancies caused by BCR-ABL, c-KIT, and PDGFR. Imatinib remains the most prevalent and frequently used for CML therapy due to its effectiveness and manageable adverse reactions . Generic versions of Imatinib have shown similar pharmacologic properties and efficacy compared to the original branded form .

Mechanism of Action |
Imatinib mesylate is a protein-tyrosine kinase inhibitor that inhibits the BCR-ABL tyrosine kinase, the constitutively active tyrosine kinase created by the Philadelphia chromosome abnormality in CML.Although the function of normal BCR is still unclear, ABL activation is overexpressed in various tumors and is heavily implicated in cancer cells growth and survival. Imatinib inhibits the BCR-ABL protein by binding to the ATP pocket in the active site, thus preventing downstream phosphorylation of target protein. Imatinib is also an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF) and stem cell factor (SCF), c-Kit, and inhibits PDGF- and SCF-mediated cellular events. In vitro, imatinib inhibits proliferation and induces apoptosis in GIST cells, which express an activating c-Kit mutation. |
