In the present investigation, two series of 2,5-disubstituted-3-imidazol-2-yl-pyrrolo[2,3-b]pyridines (2a-l) and thieno[2,3-b]pyridines (3a-l) were designed as analogs of BL 11282 (1). The in vitro glucose dependent insulinotropic activity of all the test compounds was evaluated using RIN5F cell based assay and all the test compounds showed glucose and concentration dependent insulin secretion. The in vivo antidiabetic activities of most potent compounds from each series (I and II) were assessed in C57BL/6J mice. Compounds I and II showed dose dependent insulin secretion and significant glucose reduction in vivo. In general, compounds I and II were found to be equipotent at all the three different doses selected and with respect to BL 11282, both the test compounds were found to be more potent, at all the time points. This study involved multiple reactions and reactants, such as 5-Chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (cas: 145934-81-2Quality Control of 5-Chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine).
5-Chloro-2-methyl-1H-pyrrolo[2,3-b]pyridine (cas: 145934-81-2) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of 鈭?8.7 脳 10鈭? cm3路mol鈭?.The molecular electric dipole moment is 2.2 debyes.
