Synthesis, antidiabetic activity and molecular docking study of rhodanine-substitued spirooxindole pyrrolidine derivatives as novel α-amylase inhibitors
In a sustained search for novel α-amylase inhibitors for the treatment of type 2 diabetes mellitus (T2DM), we report herein the synthesis of a series of nineteen novel rhodanine-fused spiro[pyrrolidine-2,3′-oxindoles]. They were obtained by one-pot three component [3 + 2] cycloaddition of stabilized ...
Modelling the response of Antarctic marine species to environmental changes. Methods, applications and limitations
Ecological modelling is nowadays widely used to highlight the environmental conditions that influence the species ecological niche and better understand their response to environmental changes. Methodological challenges are however present for Southern Ocean marine case studies and it is important ...
1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne
A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of ...
4′-(5-Methylfuran-2-yl)-2,2′:6′,2″-terpyridine: A New Ligand Obtained from a Biomass-Derived Aldehyde with Potential Application in Metal-Catalyzed Reactions
The new ligand 4′-(5-methylfuran-2-yl)-2,2′:6′,2″-terpyridine (1) was prepared in one step from 2-acetylpyridine and 5-methylfurfural. The latter is an aldehyde that can be readily obtained from biomass. The new terpyridine molecule was characterized by 1H and 13C-NMR spectroscopy as well as by ...
Diversity-oriented Synthesis of Spiropyrrolo[1, 2-a]isoquinoline Derivatives via Diastereoselective and Regiodivergent Three-component 1,3-Dipolar Cycloaddition Reactions: In vitro and in vivo Evaluation of the Antidiabetic Activity of Rhodanine Analogues
An efficient diastereoselective route is developed to get access to novel spiropyrrolo[1,2-a]isoquinoline-oxindole skeletons by a one-potthree-component [3 + 2] cycloaddition reaction of (Z)-5-arylidene-1,3-thiazolidine-2,4-diones, isatin derivatives, and 1,2,3,4-tetrahydroisoquinoline (THIQ). ...
