  radical intermediate was supported by the results of the experimental works and the DFT-computational studies. X-ray crystal structure analysis of two of 5-oxohexahydroquinoline compounds indicated that i). The C4-aryl ring occupies the pseudo-axial position of the twisted-boat conformation of the heterocyclic dihydropyridine ring and, ii). Owing to the steric ortho-repulsion, the C2-aryl ring has a non-planar

  A series of 2,4-disubstituted polyhydroquinoline were synthesized and evaluated for their in vivo antihyperglycemic as well as antidyslipidemic activities. Several synthesized compounds have exhibited promising in vivo antihyperglycemic in SLM, STZ-S, and db/db mice model along with significant lipid and TG modulating activity. All these compounds were evaluated in various in vitro models of diabetes to know the possible mechanism of their antihyperglycemic action. Interestingly, compounds 3a-r (diaryl substitution) have exhibited promising protein-tyrosine phosphatase 1B (PTP1B) inhibitory activity whereas, compounds 5a-d (acid substituted) have shown significant glycogen phosphorylase activity.
