discussed the molecular mechanism responsible for the HSA protective effect of Oct and N-AcMet based on the structure. The findings obtained from this study suggest that N-AcMet acts positively as useful stabilizer for albumin formulated products such as functionalized HSA and HSA fusion proteins. The use of Hemoglobin-vesicles for delivering medicinal gas for the treatment of intractable disorders. Taguchi K () Yamasaki K () Sakai H () Maruyama T () Otagiri M () J Pharm Sci., Vol.106(9), pp.2392-2400 2017 (29) doi: 10.1016/j.xphs.2017.04.006 Bioactive gaseous molecules, such as oxygen (O2) and carbon monoxide (CO), are essential elements for most living organisms to maintain their homeostasis and biological activities. An accumulating body of evidence suggests that such molecules can be used in clinics as a medical gas in the treatment of various intractable disorders. Recent developments in hemoglobin-encapsulated liposomes, namely hemoglobin vesicles (HbV), possess great potential for retaining O2 and CO and could lead to strategies for the development of novel pharmacological agents as medical gas donors. HbV with either O2 or CO bound to it has been demonstrated to have therapeutic potential for treating certain intractable disorders and has the possibility to serve as diagnostic and augmenting product by virtue of unique physicochemical characteristics of HbV. The present review provides an overview of the present status of the use of O2- or CO-binding HbV in experimental animal models of intractable disorders and discusses prospective clinical applications of HbV as a medical gas donor.
