Anti-TSHR Antibody (M22) is a selective agonist targeting TSHR (thyroid-stimulating hormone receptor), acting through competitive binding to the extracellular domain of TSHR. Anti-TSHR Antibody (M22) can mimic the biological effects of thyroid-stimulating hormone (TSH), activating downstream cAMP-PKA and other signaling pathways. Anti-TSHR Antibody (M22) can stimulate the proliferation of thyroid follicular epithelial cells and human umbilical vein endothelial cells (HUVECs), promote angiogenesis and tube formation, cell migration, and also upregulate the expression of angiogenesis-related proteins such as PROX1. Anti-TSHR Antibody (M22) can be used in research areas such as the mechanisms of goiter formation in Graves' disease (GD), angiogenesis regulation, and TSHR antagonist screening.

HBTU (N-HBTU) is a guanidinium-based peptide coupling reagent and immunological sensitizer. HBTU can be used in combination with bases such as DIPEA (HY-130142) to complete coupling reactions, with HOBt and TMU as by-products. HBTU is a standard reagent in automated solid-phase peptide synthesis, particularly for the Fmoc/tBu strategy, which effectively promotes coupling steps, but it is not suitable for sterically hindered amino acids or dipeptide derivatives. HBTU can induce rhinitis, dermatitis, bronchial asthma and severe allergic reactions. HBTU can be used to study the pathogenesis of allergic reactions, occupational rhinitis, allergic contact dermatitis and bronchial asthma.

Desloratadine (Sch34117) is an orally active and selective H1 receptor antagonist (K_i=0.9 nM) with anti-inflammatory and anti-allergic activities. Desloratadine inhibits the release of histamine and LTC4 from human basophils and targets the regulatory signals of IL-4 and IL-13 production in basophils. Desloratadine significantly alleviates SAR symptoms in patients with concurrent asthma and can be used in the study of seasonal allergic rhinitis and chronic idiopathic urticaria.

Vixarelimab (KPL-716) is a human anti-oncostatin M (OSM) receptor β subunit monoclonal antibody. Vixarelimab inhibits IL-31 and OSM signalling. Vixarelimab can be used in studies of inflammatory skin diseases such as atopic dermatitis and itchy nodular rash.

PPACK TFA is a potent, peptidic inhibitor targeting thrombin and granzyme GZMK. PPACK TFA specifically blocks the activities of thrombin and GZMK, thereby inhibiting thrombin-mediated PAR-1 cleavage, as well as downstream inflammatory and procoagulant signaling pathways. Through stabilizing IκB proteins, blocking NF-κB activation and reducing systemic levels of proinflammatory/procoagulant biomarkers, PPACK TFA exerts multiple effects including anti-inflammatory, antithrombotic, barrier repair, and inhibition of atherosclerotic plaque progression. PPACK TFA binds to platelets without interference from kininogen, effectively limiting acute thrombus growth and reducing eosinophil infiltration and goblet cell hyperplasia in asthma models. PPACK TFA is an important tool molecule for investigating the mechanisms of atherosclerosis, asthma and related thromboinflammatory diseases.
