The Impact

Background: Prophylactic treatment regimens to prevent mother-to-child HIV transmission include protease inhibitors Lopinavir and Ritonavir. Lopinavir and Ritonavir have been reported to be able to induce intracellular oxidative stress in diverse cellular models, however scarce informations are available about protease inhibitor effects of in the central nervous system (CNS). In our study we evaluated the impact of protease inhibitors on a cell neuronal model. Methods: We treated a neuroblastoma cell line (SH-SY5Y) with increasing doses of Lopinavir and Ritonavir (0.1-1-10-25-50 µM), used alone or in combination, evaluating the impact of these drugs in terms of mitochondrial activity, with MTT cell proliferation assay; mRNA expression of heme oxygenase (HemeOH) and reactive oxygen species (ROS) levels with 2',7'-dichlorofluorescin diacetate (H2DCFDA) in order to assess oxidative stress; apoptotic cell death with flow cytometry. Results: We observed that Lopinavir and Ritonavir treatment, at 25 and/or 50 µM concentrations, induced mitochondrial damage, increase of heme oxygenase RNA expression levels and ROS generation, followed by apoptosis in SH-SY5Y. Conclusions: Our in vitro model demonstrates a damaging effect of HIV protease inhibitors on the neuroblastoma cell line, thus partially mimicking the impact of these drugs on the CNS of children born to HIV positive mothers undergone to antiretroviral treatment.

We report herein the evaluation of various pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5-amines as potential cytotoxic agents. These molecules were obtained by developing the multicomponent Groebke–Blackburn–Bienaymé reaction to yield various pyrido[2′,1′:2,3]imidazo[4,5-c]quinolines which are isosteres of ellipticine whose biological activities are well established. To evaluate the anticancer potential of these pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5-amine derivatives in the human neuroblastoma cell line, the cytotoxicity was examined using the WST-1 assay after 72 h drug exposure. A clonogenic assay was used to assess the ability of treated cells to proliferate and form colonies. Protein expressions (Bax, bcl-2, cleaved caspase-3, cleaved PARP-1) were analyzed using Western blotting. The colony number decrease in cells was 50.54%, 37.88% and 27.12% following exposure to compounds 2d, 2g and 4b respectively at 10 μM. We also show that treating the neuroblastoma cell line with these compounds resulted in a significant alteration in caspase-3 and PARP-1 cleavage.
