Design, Synthesis, Safener Activity, and Molecular Docking of Novel N-Substituted Thiazide/Thiazole Derivatives

A series of novel substituted thiazide/thiazole compounds were designed by splicing active groups and bioisosterism. The title compounds were synthesized via the cyclization, acylation, and carbamylation. All the compounds were characterized by IR, 1H-NMR, 13C-NMR, and HRMS. The single crystal of compound 3f was determined by X-ray crystallography. The biological activity tests indicated that all the compounds showed potential safener activity to the herbicide chlorsulfuron, in which compound 3e showed almost the same level as the commercialized safener AD-67. The molecular docking results were in good agreement with the bioassay results, which demonstrated that compound 3e might compete with chlorsulfuron in the acetolactate synthase active site, causing the herbicide ineffective in maize.

Geosmin biosynthesis. Mechanism of the fragmentation-rearrangement in the conversion of germacradienol to geosmin

Geosmin (1) is responsible for the characteristic odor of moist soil. Incubation of farnesyl diphosphate (2, FPP) with recombinant Streptomyces coelicolor germacradienol/geosmin synthase generated geosmin (1), germacradienol (3), germacrene D (4), octalin 5, and acetone, which was trapped as 2,2-dimethylthiazolidine (9) by reaction with cysteamine. The acetone was shown to be derived by fragmentation of the 2-hydroxypropyl moiety of germacradienol by incubation with [13,13,13-2H3]FPP (2a), giving rising to the corresponding derivative of d3-acetone, 9a. GC-MS analysis of the labeling pattern of [6-2H]geosmin (1b) resulting from the incubation of germacradienol/geosmin synthase with [2-2H]FPP (2b) revealed that the H-2 proton on FPP undergoes the predicted 1,2-hydride shift to ring B of geosmin. Both sets of experimental results are consistent with a proposed mechanism of geosmin formation involving protonation-cyclization of germacradienol with loss of the 2-hydroxypropyl moiety as acetone by a retro-Prins fragmentation to give octalin intermediate 5, followed by protonation of 5, 1,2-hydride shift, and capture of water.
