Synthesis, α-glucosidase inhibition and in silico studies of some 4-(5-fluoro-2-substituted-1H-benzimidazol-6-yl)morpholine derivatives

In this study, a new series of 4-(5-fluoro-2-substituted-1H-benzimidazol-6-yl)morpholine derivatives has been synthesized and screened for their α-glucosidase inhibitory potential. All molecules showed a considerable α-glucosidase inhibitory potential with IC50 values ranging from 20.46 ± 0.21 to 0.18 ± 0.01 μg/mL when compared with the acarbose (IC50 = 8.16 ± 0.12 μg/mL) as the standard. Compound 4 k having methoxy group on phenyl ring had the highest inhibitory effect with IC50 = 0.18 ± 0.01 μg/mL value among the examined compounds. Electron-donating groups such as methyl and methoxy on the phenyl ring played an important role in the inhibition. Also, the Lineweaver-Burk plots analysis displayed that the inhibition type of 4k was the competitive mode like acarbose as standard. In silico studies were also performed to explore the binding interaction of the most active compound.

HPK1 INHIBITORS AND METHODS OF USING SAME

Thienopyridinone compounds of Formula (I) and pharmaceutically acceptable salts thereof are described. In these compounds, one of X1; X2, and X3 is S and the other two are each independently CR, wherein R and all other variables are as defined herein. The compounds are shown to inhibit HPK1 kinase activity and to have in vivo antitumor activity. The compounds can be effectively combined with pharmaceutically acceptable carriers and also with other immunomodulatory approaches, such as checkpoint inhibition or inhibitors of tryptophan oxidation.

Chemo-enzymatic synthesis and biological evaluation of 5,6-disubstituted benzimidazole ribo- and 2′-deoxyribonucleosides

A number of new 5,6-disubstituted benzimidazoles have been prepared and their substrate properties for recombinant E. coli purine nucleoside phosphorylase (PNP; the product of the deoD gene) in the transglycosylation reaction were investigated. The heterocyclic bases showed good substrate activity for PNP and the ribo- and 2-deoxyribonucleosides were synthesized. The predominant (OMe and OEt) or exclusive (Oi-Pr, morpholino, and N-methylpiperazino) formation of the 5-substituted 6-fluoro-1-(β-d- ribofuranosyl)benzimidazoles was observed. The formation of the regioisomeric 6- methoxy-, 6-ethoxy-, or 6-isopropoxy-substituted 1-(2-deoxy-β-d- ribofuranosyl)-5-fluorobenzimidazoles was observed in the trans-2- deoxyribosylation reaction of the corresponding bases. The predominant or exclusive formation of the regioisomeric N1-nucleosides with bulky 5-substituents of 6-fluorobenzimidazole points to a large hydrophobic pocket in the E. coli PNP active site that can accommodate these groups. The biological activity of the synthesized nucleosides was studied and revealed no inhibitory activity against a broad variety of DNA and RNA viruses. The compounds also lacked significant cytotoxicity. Georg Thieme Verlag Stuttgart New York.

Synthesis of substituted 2-ethoxycarbonyl- and 2-carboxyquinoxalin -3 ones for evaluation of antimicrobial and anticancer activity

A series of variously substituted quinoxalin-3-ones bearing an ethoxycarbonyl or carboxy group in the C-2 position has been prepared and their structures proved by 1H NMR spectroscopy. The obtained compounds were investigated in vitro for antimicrobial and anticancer activities. Preliminary results showed a moderate activity against a few strains of bacteria but no significant anticancer and anti-HIV activity.

Fluorinated Quinoxalines: Synthesis and Alkylation

6,7-Difluoro- and 6-fluoro-7-morpholino(4-methylpiperazinyl, 2,6-dimethylpiperazinyl)quinoxalines have been synthesized from aromatic diamines and glyoxal, and their alkylation with Meerwein reagent has been studied. A procedure has been developed for preparation of pure 1-ethylquinoxalinium salts whose structure has been confirmed by 1H NMR spectra and X-ray analysis.
