AN 2728 CAS NO.906673-24-3

AN 2728 (Crisaborole) is a novel, small-molecule benzoxaborole-class drug substance renowned for its topical anti-inflammatory efficacy and non-steroidal mechanism. It is primarily utilized as a high-value active pharmaceutical ingredient (API) in the formulation of dermatological ointments and creams targeting chronic skin inflammation. With excellent skin permeability and a favorable safety profile, this boron-containing compound is a preferred choice for pharmaceutical manufacturers developing next-generation treatments for pediatric and adult populations suffering from inflammatory dermatoses.

1.MECHANISM OF ACTION

AN 2728 functions as a potent and selective phosphodiesterase-4 (PDE4) inhibitor, targeting the enzyme's catalytic site via its unique boron-based structure. By blocking PDE4-mediated hydrolysis of cyclic AMP (cAMP), it elevates intracellular cAMP levels in immune cells, which in turn suppresses the transcription and release of key pro-inflammatory cytokines such as TNF-α, IL-6, IL-12, and IL-23. This upstream modulation of the inflammatory cascade effectively reduces T-cell activation and neutrophil infiltration, addressing the underlying immune dysregulation in skin disorders without the side effects associated with systemic corticosteroids.

2.PRODUCT INDICATIONS

This compound is specifically indicated for the development of topical therapeutics for mild to moderate atopic dermatitis (eczema) in patients aged two years and older, as well as for psoriasis vulgaris. It serves as the critical raw material for compounding pharmacies and pharmaceutical companies formulating non-steroidal, non-calcineurin inhibitor alternatives. Additionally, research-grade AN 2728 is used in preclinical studies investigating PDE4-driven inflammatory pathways and for the development of novel topical solutions for allergic contact dermatitis and other immune-mediated skin conditions.

3.CLINICAL EFFICACY OF PRODUCT

Clinical studies demonstrate that Felypressin significantly prolongs the anesthetic effect and reduces intraoperative bleeding, with a duration of action comparable to epinephrine-containing formulations but with a markedly reduced impact on heart rate and blood pressure. Its efficacy is well-established in patients with cardiovascular risk factors, where it provides stable hemodynamic conditions during dental treatment. Research confirms its ability to deliver adequate anesthesia and hemostasis while minimizing adverse systemic effects, ensuring patient safety and procedural success.
