WebAug 8, 2008 · (B) ΔM plot of the modified peptide with a mass shift of −48 Da, corresponding to a dethiomethylation of oxidized methionine. Background noise, which is evenly distributed over the Δ M plots, is caused by matches of noise peaks in the experimental MS/MS spectrum within the given mass tolerance of ±0.7 Da.

WebDethiomethylation of 131 with Raney Ni in EtOH at reflux temperature for 6 h gave 2,3,4,6-tetrahydro-1 H-indolo[2,3-b]quinoline (132). Subsequent dehydrogenation of 132 with DDQ in refluxing 1,4-dioxane furnished the requested 6 H -indolo[2,3- b ]quinoline ( 133 ) in 88% yield ( Scheme 37 ). WebAug 3, 2014 · Notably, the non-mevalonate pathway is repressed, whereas the rubrum-type methionine salvage pathway contributes to isoprenoid biosynthesis upon 5′-methylthioadenosine feeding.
