By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Enzymes and Coenzymes - Hydro-Lyases have been presented. According to news reporting originating from Eugene, Oregon, by NewsRx correspondents, research stated, “Carbonyl sulfide (COS) releasing scaffolds are gaining popularity as hydrogen sulfide (H2S) donors through exploitation of the carbonic anhydrase (CA)-mediated hydrolysis of COS to H2S. The majority of compounds in this emerging class of donors undergo triggerable decomposition (often referred to as self-immolation) to release COS, and a handful of different COS-releasing structures have been reported.”

Funders for this research include Sloan Foundation, Dreyfus Foundation, NIH, NSF/GRFP, NSF.

Our news editors obtained a quote from the research from the Institute of Molecular Biology, “One benefit of this donation strategy is that numerous caged COS-containing core motifs are possible and are poised for development into self-immolative COS/H2S donors. Because the intermediate release of COS en route to H2S donation requires CA, it is important that the COS donor motifs do not inhibit CA directly. In this work, we investigate the cytotoxicity and CA inhibition properties of different caged COS donor cores, as well as caged CO2 and CS2 motifs and non-self-immolative control compounds.”

According to the news editors, the research concluded: “None of the compounds investigated exhibited significant cytotoxicity or enhanced cell proliferation at concentrations up to 100 mu M in A549 cells, but we identified four core structures that function as CA inhibitors, thus providing a roadmap for the future development of self-immolative COS/H2S donor motifs.”
