Gaseous signaling molecules (GSMs) including nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H 2 S) have presented excellent therapeutic efficacy such as anti-inflammatory, anti-microbial and anti-cancer effects and multiple biomedical applications in recent years. As the three most vital signaling molecules in human physiology, these three GSMs show so intertwined and orchestrated interactions that the synergy of multiple gases may demonstrate a more complex therapeutic potential than single gas delivery. Consequently, researchers have been devoted to developing codelivery systems of GSMs by synthesizing a single molecule as a dual donor to maximize the gaseous therapeutic efficacy. In this minireview, we summarize the recent developments of molecules or materials enabling codelivery of GSMs for biomedical applications. It appears that compared with the abundant cases of codelivery of NO and H 2 S, research on codelivery of CO and the other two GSMs separately remains to be explored., (© 2024 Wiley-VCH GmbH.)

Nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S) are considered endogenous gaseous signaling molecules that play crucial roles in regulating physiological and pathological pathways. Among these molecules, NO has demonstrated unique advantages and clear efficacy in the treatment of blood coagulation in cardiovascular diseases. As a result, the development of NO‐releasing materials for anticoagulant therapeutics has garnered significant attention. However, unlike traditional anticoagulant treatments such as heparin and oral anticoagulants, NO, a gaseous molecule under ambient conditions, cannot be administered orally, through injection, or via the skin. Consequently, researchers have focused on developing NO‐releasing macromolecular systems by combining various donors with polymeric materials for use in anticoagulant therapeutics. This minireview aims to highlight the methods and advancements in constructing such NO‐releasing macromolecular systems and exploring their applications in anticoagulant therapeutics.
