Synthesis of novel dihydropyridothienopyrimidin-4,9-dione derivatives

A novel molecular scaffold, dihydropyridothienopyrimidin-4,9-dione, was synthesized from benzylamine or p-methoxybenzylamine in six steps involving successive ring closure to form a fused ring system composed of dihydropyridone, thiophene and pyrimidone. The pharmacological versatility of the dihydropyridothenopyrimidin-4,9-dione scaffold was demonstrated by inhibitory activity against metabotropic glutamate receptor subtype 1 (mGluR1), which shows that the title compounds can serve as an interesting scaffold for the discovery of potential bioactive molecules for the treatment of human diseases.

Structure-based optimization of 2,3-dioxopyrrolidines as potential inhibitors of flaviviral methyltransferases

Various studies have shown that NS5 RNA methyltransferase (MTase) is a key enzyme involved in mRNA capping, a step crucial for flaviviral replication. Therefore, it has been identified as a potential target for therapeutic intervention in infections arising due to flaviviruses. In this paper, we report computer-assisted design of 2,3-dioxopyrrolidines, which were synthesised as guided by molecular docking studies on DENV and ZIKA MTase. Their chemical structures and geometric configuration were characterized by FT-IR, NMR (13C and 1H), MS and small molecule X-ray crystallography. Subsequently, their inhibitory potential was evaluated using an enzyme-based assay in DENV MTase (N7 and 2'O-MTase) and Zika virus MTase (N7 and 2'O-MTase). Furthermore, these molecules were also screened against RNMT (human N7 MTase). The most potent lead (compound W07) is seen to inhibit MTase from DENV with IC50 = 24.6±3.8 M and ZIKA with IC50 = 9.0±1.7 M. However, it also inhibits human N7 MTase, indicating plausible toxicity in humans. There is scope to further optimize these molecules to achieve selectivity towards flaviviral MTases.

Novel synthesis of 4,4-difluoropyrido[4,3-b]indoles via intramolecular Heck reaction

Various difluoropyridoindoles were synthesized via a palladium-catalyzed intramolecular Heck reaction as a key step. Thus, ortho-bromoanilines and difluoropiperidinone were treated with (PPh3)2PdCl 2 and base in pyridine to give the regioselective cyclized heterocycles in modest to satisfactory yields. Copyright

Lipase-catalyzed aza-michael reaction on acrylate derivatives

A methodology has been developed for an efficient and selective lipase-catalyzed aza-Michael reaction of various amines (primary and secondary) with a series of acrylates and alkylacrylates. Reaction parameters were tuned, and under the optimal conditions it was found that Pseudomonas stutzeri lipase and Chromobacterium viscosum lipase showed the highest selectivity for the aza-Michael addition to substituted alkyl acrylates. For the first time also, some CLEAs were examined that showed a comparable or higher selectivity and yield than the free enzymes and other formulations.

7-Oxopyrrolopyridine-derived DPP4 inhibitors - Mitigation of CYP and hERG liabilities via introduction of polar functionalities in the active site

Design, synthesis, and SAR of 7-oxopyrrolopyridine-derived DPP4 inhibitors are described. The preferred stereochemistry of these atropisomeric biaryl analogs has been identified as Sa. Compound (+)-3t, with a Ki against DPP4, DPP8, and DPP9 of 0.37 nM, 2.2, and 5.7 μM, respectively, showed a significant improvement in insulin response after single doses of 3 and 10 μmol/kg in ob/ob mice.
