      Product Detail  


    CAS 37025-55-1 corresponds to Carbetocin, a synthetic cyclic oxytocin analog, rather than native Oxytocin. Carbetocin has the reference molecular formula C45H69N11O12S and a molecular weight of approximately 988.16 g/mol. Its modified cyclic structure makes it a useful research material for oxytocin-receptor pharmacology, ligand comparison, smooth-muscle signaling, cyclic-peptide stability, and structure-activity studies.

    This defined cyclic-peptide reference is suitable for receptor assays, peptide pharmacology, and comparative sequence-structure studies. It can be compared with native Oxytocin and related vasopressin-family peptides to evaluate how sequence and structural modifications influence receptor response and persistence. The material is supplied only for laboratory research and analytical use.

    Mechanism of Action

    Carbetocin is studied as an agonist at the oxytocin receptor, a G-protein-coupled receptor. Receptor activation can initiate calcium-linked and other downstream signaling responses, with the measured outcome depending on receptor density, cell background, assay format, incubation period, and the selected endpoint.

    Its modified cyclic architecture is designed to resist some forms of peptide breakdown relative to native Oxytocin. This supports comparative studies of ligand stability, receptor activation, desensitization, internalization, and functional persistence. Selectivity should be evaluated experimentally because related peptide receptors can show overlapping ligand recognition in some systems.


    Research Value

    Carbetocin provides a recognized reference for connecting cyclic-peptide structure with receptor-level and functional readouts. It is useful for distinguishing how a modified ligand behaves compared with the native peptide and for building concentration-response, time-course, receptor-selectivity, and signaling-bias studies.

    It is well suited to receptor pharmacology and cyclic-peptide development. Reliable identity and purity documentation are particularly important because closely related oxytocin-family peptides may differ by only a small number of structural features yet produce different assay profiles.


    Core Research Applications

    Oxytocin-receptor pharmacology. Used in binding, activation, concentration-response, desensitization, and receptor-internalization studies.

    Cyclic-peptide structure-activity research. Suitable for comparing native peptide, modified analogs, and related receptor ligands.

    Smooth-muscle signaling models. Supports studies using calcium flux, contraction-related, or downstream molecular endpoints.

    Ligand stability and persistence. Used to evaluate how structural modification affects peptide processing and time-dependent activity.

    Assay development and reference testing. Useful as a defined comparator in receptor screening and method-validation workflows.


    Product Advantages

    Correctly matched product name and CAS identity support reliable material verification.

    Recognized cyclic Oxytocin analog for receptor and structure-activity research.

    Research-grade purity options with batch-specific HPLC and mass-analysis documentation.

    Flexible quantities and packaging for receptor assays, comparative studies, and method development.

    Custom analog synthesis and additional analytical support available for qualified projects.

    ECHEMI Editorial Reference
    Carbetocin (Lonactene; Duratocin) is an obstetric drug used to control postpartum hemorrhage and bleeding after giving birth; an agonist at peripheral oxytocin receptors.
    Carbetocin is an alternative synthetic oxytocin-receptor agonist available in Canada, the United Kingdom, and other countries,but not the United States. A large multinational randomized noninferiority trial (N=29,645) found that carbetocin was noninferior to oxytocin for prevention of postpartum hemorrhage and need for additional uterotonic agents after vaginal delivery. Carbetocin has a longer duration of action than oxytocin, eliminating the need for prolonged infusion.
    ChEBI: Oxytocin in which the hydrogen on the phenolic hydroxy group is substituted by methyl, the amino group on the cysteine residue is substituted by hydrogen, and the sulfur of the cysteine residue is replaced by a methylene group. A synthetic carba-analogue o oxytocin, it is used to control bleeding after giving birth. Like oxytocin, it causes contraction of the uterus.
