Activity of novel quinoxaline-derived chalcones on in vitro glioma cell proliferation

Gliomas are the most common and devastating tumors of the central nervous system (CNS). Many pieces of evidence point out the relevance of natural compounds for cancer therapy and prevention, including chalcones. In the present study, eight synthetic quinoxaline-derived chalcones, structurally based on the selective PI3Kgamma inhibitor AS605240, were evaluated for anti-proliferative activity and viability inhibition using glioma cell lines from human and rat origin (U-138 MG and C6, respectively), at different time-periods of incubation and concentrations. The results revealed that four chalcones (compounds 1, 6, 7 and 8), which present methoxy groups at A-ring, displayed higher efficacies and potencies, being able to inhibit either cell proliferation or viability, in a time- and concentration-dependent manner, with an efficacy that was greater than that seen for the positive control compound AS605240. Flow cytometry analysis demonstrated that incubation of C6 cells with compound 6 led to G1 phase arrest, likely indicating an interference with apoptosis. Furthermore, compound 6 was able to visibly inhibit AKT activation, allied to the stimulation of ERK MAP-kinase. The chalcones tested herein, especially those displaying a methoxy substituent, might well represent promising molecules for the adjuvant treatment of glioma progression.

Design, synthesis, and biological evaluation of substituted-N-(thieno[2,3-b]pyridin-3-yl)-guanidines, N-(1H-pyrrolo[2,3-b]pyridin-3-yl)-guanidines, and N-(1H-indol-3-yl)-guanidines

Sulfonylureas stimulate insulin secretion independent of the blood glucose concentration and therefore cause hypoglycemia in type 2 diabetic patients. Over the last years, a number of aryl-imidazoline derivatives have been identified that stimulate insulin secretion in a glucose-dependent manner. In the present study, we have developed three series of substituted N-(thieno[2,3-b]pyridin-3-yl)-guanidine (2a-l), N-(1H-pyrrolo[2,3-b]pyridin-3-yl)-guanidine (3a-l), and N-(1H-indol-3-yl)-guanidine (4a-l) as new class of antidiabetic agents. In vitro glucose-dependent insulinotropic activity of test compounds 2a-l, 3a-l, and 4a-l was evaluated using RIN5F (Rat Insulinoma cell) based assay. All the test compounds showed concentration-dependent insulin secretion, only in presence of glucose load (16.7 mmol). Some of the test compounds (2c, 3c, and 4c) from each series were found to be equipotent to BL 11282 (standard aryl-imidazoline), which indicated that the guanidine group acts as a bioisostere of imidazoline ring system.
