We describe an efficient route towards the synthesis of fusedbicyclic glutarimides using facile [3+3] reaction of α-sulfonylacetamides with different α,β-unsaturated esters as the key step. Intramolecular cyclization of 4-substituted 3-sulfonylglutarimide to form 5,6-, 6,6- or 6,7-fused bicyclic glutarimides was accomplished via alkylation, oxidative cyclization or ring-closing metathesis in modest

This invention relates with anti-tumor activities of new compounds containing an adamantyl group or analogs thereof. The invention also relates with the medication applications of anti-tumor and other diseases by this kind of compounds with the combination of S, P, T structures containing adamantyl group and the formation of stereoisomer, tautomers, prodrug, pharmaceutically acceptable salts, complex salts or solvates to their anticancer application and anticancer agents, which have the following general formula:
biosynthesis. Structure‐based virtual screening of about 3 000 000 commercially available compounds against the crystal structure of the glycosyltransferase (GT) domain of the Staphylococcus aureus penicillin‐binding protein 2 (S. aureus PBP2) resulted in identification of an isatin derivative, 2‐(3‐(2‐carbamimidoylhydrazono)‐2‐oxoindolin‐1‐yl)‐N‐(m‐tolyl)acetamide (4) as a novel potential GT inhibitor.
