    Buy Ketotifen Fumarate: Premium Grade Compound for Laboratory Studies

    When researching allergic mechanisms and histamine pathways, high-quality compounds with verified purity and consistent performance are required. When labs buy ketotifen fumarate for their research, the supplier choice can impact experimental outcomes and data reliability. This guide covers the molecular properties, research applications and quality considerations for selecting ketotifen fumarate as a research compound.

    Ketotifen fumarate is a valuable tool in immunology and allergy research, working through dual mechanisms that makes it useful for studying mast cell biology and histamine receptor interactions. Understanding its chemical properties, storage requirements and research applications allows scientists to make informed decisions when adding this compound to their protocols.

    Molecular Structure of Ketotifen Fumarate

    The chemical characterization of ketotifen fumarate provides essential information for researchers planning their experiments. The compound’s systematic name, 4-(1-Methyl-4-piperidylidene)-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-10(9H)-one fumarate, reflects its complex benzocycloheptathiophene core structure with the fumarate salt enhancement.

    Property Specification
    Chemical Name 4-(1-Methyl-4-piperidylidene)-4H-benzo[4,5]cyclohepta[1,2-b]thiophen-10(9H)-one fumarate
    Molecular Formula C23H23NO5S
    Molecular Weight 425.5 g/mol
    PubChem CID 5282408
    CAS Number 34580-14-8

    The fumarate salt form has advantages for laboratory use, including better solubility and stability compared to the base compound. Research shows this formulation has more consistent dissolution properties in common laboratory solvents, such as DMSO and ethanol, which are used in cell studies.

    The compound’s structure contributes to its dual pharmacological profile, antihistamine and mast cell stabilizing effects. This combination makes ketotifen fumarate very useful for researchers studying histamine pathways and inflammatory mediator release.

    Mechanism of Action

    Ketotifen fumarate works through two distinct yet complementary mechanisms that makes it a valuable research compound for allergy and immunology studies. Understanding these mechanisms helps researchers design their experiments and interpret results in the context of histamine receptor biology and mast cell function.

    H1 Receptor Antagonism

    The primary action is non-competitive antagonism of histamine H1 receptors, where ketotifen binds to allosteric sites distinct from the endogenous histamine binding site. Research shows this non-competitive binding pattern results in sustained receptor blockade that cannot be easily reversed by increasing histamine concentrations, making it very useful for studying long-term histamine pathway modulation.

    Studies on receptor binding kinetics show ketotifen has prolonged residence time at H1 receptors, which correlates with longer duration of action in experimental models. This is useful for chronic urticaria research models and longer observation periods in lab settings.

    Mast Cell Stabilization

    The secondary mechanism is direct stabilization of mast cell membranes, preventing degranulation and the subsequent release of inflammatory mediators including histamine, leukotrienes and platelet-activating factor. Research shows this stabilizing effect requires repeated exposure to achieve maximum effect, typically seen after multiple dosing cycles in experimental protocols.

    In vitro studies show concentration-dependent inhibition of mast cell activation, with documented IC50 values varying depending on cell type and experimental conditions. The compound prevents both immediate and late phase inflammatory responses making it useful for studying the whole allergic cascade in research models.

    Additional research suggests ketotifen’s mast cell stabilizing effect goes beyond simple membrane effects, possibly involving modulation of calcium signaling pathways and cytoskeletal organization in these immune cells.

    Research Studies

    Laboratory studies using ketotifen fumarate have provided valuable information on allergic mechanisms and histamine receptor biology. When researchers buy ketotifen fumarate for their research, they get a compound with extensive literature documentation and established protocols for various experimental uses.

    In Vitro Applications

    Cell culture studies show ketotifen’s effect in human mast cell and basophil models, where research shows concentration dependent effects on mediator release and cellular activation. Solubility studies reveal optimal preparation methods using DMSO as a vehicle for stock solutions, ensuring consistent results across different lab settings.Mouse studies have shown anti-allergic mechanisms with focus on airway hyperresponsivity and systemic anaphylactic responses. These studies provide dose response and time course data for researchers planning similar experiments.

    Comparative Research

    Published studies comparing ketotifen to other antihistamines and mast cell stabilizers highlight its dual action profile. Research shows this combination of effects is useful for models studying chronic inflammatory processes where both immediate hypersensitivity and prolonged inflammatory cascades need to be investigated.

    The compound is a reference standard for studies of new anti-allergic compounds, providing established benchmarks for potency and mechanism of action. This is particularly useful for pharmaceutical research and compound screening.
