AI Article Synopsis

  • The study focuses on creating artificial non-equilibrium chemical reaction systems that mimic biological processes but struggled with bioorthogonality, limiting their connection to biological regulation.
  • The researchers designed a new system using olefin metathesis to produce a non-ionic amphiphile that mimics the properties of Triton X.
  • They tested this reaction system with phospholipid vesicles and red blood cells, demonstrating its potential for temporarily controlling lytic activity.

Article Abstract

The development of artificial non-equilibrium chemical reaction systems has recently attracted considerable attention as a new type of biomimetic. However, due to the lack of bioorthogonality, such reaction systems could not be linked to the regulation of any biological phenomena. Here, we have newly designed a non-equilibrium reaction system based on olefin metathesis to produce the Triton X-mimetic non-ionic amphiphile as a kinetic product. Using phospholipid vesicles encapsulating fluorescent dyes and red blood cells as cell models, we demonstrate that the developed chemical reaction system is applicable for transient control of the resulting lytic activity.
