CO as a therapeutic agent: discovery and delivery forms

Abstract

Carbon monoxide (CO) as one of the three important endogenously produced signaling molecules, termed as "gasotransmitter," has emerged as a promising therapeutic agent for treating various inflammation and cellular-stress related diseases. In this review, we discussed CO's evolution from a well-recognized toxic gas to a signaling molecule, and the effort to develop different approaches to deliver it for therapeutic application. We also summarize recently reported chemistry towards different CO delivery forms.

Keywords: CO delivery; CO-RMs; Carbon monoxide; Gasotransmitter; Organic CO prodrug.
