A facile two-step method for the construction of fused pyrrole ring leading to 5-substituted 2,3-dihydro-1H-pyrrolo[3,2,1-ij]quinolin-1-ones via C–C followed by intramolecular C–N bond forming reaction is described. In vitro pharmacological evaluation and molecular modelling studies of some of the compounds synthesized are presented.
CuI facilitated the intramolecular cyclization of 8-alkynyl substituted 2,3-dihydroquinolin-4(1H)-ones leading
to 5-subtituted 2,3-dihydro-1H-pyrrolo[3,2,1-ij]quinolin-1-ones via intramolecular C-N bond forming reaction. Some of
the synthesized compounds have shown encouraging inhibition of Sir 2 protein (a yeast homolog of mammalian SIRT1)
when tested using a yeast cell based assay. A representative compound showed dose dependent inhibition of yeast Sir 2
(IC50 = 30.09 µM) and cell growth inhibition properties when tested against different cancer cell lines. It’s in silico interactions
with sirtuins are presented.
