Sinapultide CAS NO.138531-07-4

Sinapultide (CAS 138531-07-4) is a synthetic, amphipathic peptide designed to mimic the function of pulmonary surfactant protein B (SP-B). This cGMP-manufactured peptide consists of 25 amino acids and is engineered to reduce surface tension at the air-liquid interface of the alveoli. It is primarily utilized in critical care formulations to improve lung compliance and oxygenation, playing a crucial role in the manag…

1.MECHANISM OF ACTION

Sinapultide mimics the action of endogenous surfactant protein B by inserting into the phospholipid monolayer at the alveolar surface. Its amphipathic structure allows it to facilitate the adsorption and spreading of phospholipids, stabilize the surfactant film during expiration, and prevent alveolar collapse (atelectasis). This action dramatically lowers surface tension, increases lung compliance, and improves gas exchange efficiency.


2.PRODUCT INDICATIONS

Neonatal Respiratory Distress Syndrome (RDS): For the prevention and treatment of RDS in premature infants.

Acute Respiratory Distress Syndrome (ARDS): As a therapeutic agent for improving oxygenation in adult patients with ARDS.

Surfactant Replacement Therapy: As a key active component in synthetic surfactant preparations.


3.CLINICAL EFFICACY OF PRODUCT

Clinical studies demonstrate that synthetic surfactant preparations containing Sinapultide significantly improve oxygenation (PaO2/FiO2 ratio), reduce the need for high ventilator pressures, and decrease the incidence of complications such as pneumothorax in premature infants with RDS. In adult ARDS, it has shown potential to improve lung compliance and gas exchange, contributing to reduced mortality and shorter duration of mechanical ventilation.
