Do ‘gasotransmitters’ need to be gases? Andy makes the case in Redox Biology for Protic Small Molecule Bioregulators (PSMBs): a cross-cutting class of small molecules where protonation states impact biological speciation, permeability, & action. @agdavis98

Excited to share this work with wundergrad Addison in @angew_chem where we showcase the synthetic utility of contact-ion stabilized RSSe- for metal thioselenides, the use of 77Se NMR to probe S-Se bond polarization, and insights into thiolate persulfidation on nucleophilicity
Curious about the impacts of Lewis acids on persulfide & thioselenide chemistry? Check out Keyan & Addison’s paper using isolated ZnSSR & ZnSeSR complexes to directly study reactivity. Lots of insights from 77Se NMR & XRD! @keyanl10 @angew_chem

Another contribution from our research group on the catalytic reduction of nitrite: A Mononitrosyl Diiron(II) Compound Catalyzes the Reduction of Nitrite to Nitric Oxide | Inorganic Chemistry
pubs.acs.org
A diiron(II) compound, [Fe2(HPTP)(NCS)3(DMF)] (1), mediated the direct reduction of nitrite (NO2–) to nitric oxide (NO) in 100% yield and allowed the generation of a mononitrosyl diiron(II) compound,...
