What is Super Mini-B?

Super Mini-B is an engineered surfactant protein B analog with a stabilized helix-turn-helix structure. It is built to improve adsorption, film resilience, and resistance to surfactant inactivation in damaged lungs.

Key Benefits & Mechanisms

improves adsorption

resists inhibition by plasma proteins

supports gas exchange

Research Summary

Super Mini-B has repeatedly outperformed simpler SP-B mimics in biophysical and animal studies. It is a leading candidate for next-generation surfactant replacement, but it remains experimental.
