Abstract

New advancements in therapeutic proteins, antibodies, and cells have triggered a revolution in pharma R&D and manufacturing. Mosaic Biosciences, Inc. has developed a platform thiol-ene click chemistry technology that allows for encapsulation and delivery of these therapeutics. The thiol-ene chemistry is fast and bio-orthogonal: the reaction occurs under physiological conditions, rendering bioconjugation and/or curing of formulation in just 2-3 seconds.

Mosaic Biosciences’ proprietary portfolio contain a library of synthetic polymers and various biological components, bio-orthogonal conjugation methods, and formulation techniques. This talk will cover the unique feature and advantages of thiol-ene chemistry that differ from Michael addition, the feasibility of our technology in surgical uses and in cell encapsulation, a showcase of protein encapsulation and controlled delivery, and results from in vivo studies demonstrating safety and applicability of Mosaic’s technology in wound healing.
