PBMC cell surface thiol levels were followed by flow cytometry as described above. Thiol levels increased in a time-dependent manner which indicates labile disulfide bond reduction (figure 5 a).
WebHydrogen sulfide releasing agents (or H 2 S donors) have been recognized gasotransmitters with potent cytoprotective and anticancer properties. However, the clinical application of H 2 S donors has been hampered by their fast H 2 S-release, instability, and lack of tumor targeting, despite the unclear molecular mechanism of H 2 S action. Here we rationally … Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. Because sulfur atoms are larger than oxygen atoms, C−S bond lengths – typically around 180 picometres – are about 40 picometers longer than typical C−O bonds. The C−S−H angles approach 90° whereas the angle for the C−O−H group is more obtuse. In solids and liquids, the h…
