Such reactions are helpful in achieving cellular level targets with a controlled release of the CO amount. When these molecules are inserted into the human body, CO is released from these compounds at a controlled rate under certain conditions or/and triggers. CO is covalently attached with metal carbonyl complexes (MCCs), which generate various CORMs such as CORM-1, CORM-2, CORM-3, ALF492, CORM-A1 and ALF186. To address these issues, researchers have adopted alternative strategies regarded as CO-releasing molecules (CORMs).

For the indirect CO inhalation method, developers are facing certain problems, such as its inability to achieve the specific cellular targets and how to control the dosage of CO. Indirect CO insertion offers an advantage of avoiding toxicity as compared to direct CO insertion. Mainly, there are two types of CO insertion techniques into the human body, i.e., direct and indirect CO insertion. Recently, research on therapeutic applications using the CO treatment has gained much attention due to its nontoxic nature, and its injection into the human body using several conjugate systems. If this characteristic is utilized in a controlled manner, it can act as a cell-signaling agent for important pathological and pharmacokinetic functions hence offering many new applications and treatments. Carbon monoxide (CO) imparts toxic effects to biological organisms at higher concentration. The CO-releasing materials (CORMats) are used as substances for producing CO molecules for therapeutic purposes.
