Dose-Dependent Evaluation of Percentages of Cell Death in Primary Cultures of Rat Cortical Neurons Exposed to HDAC Inhibitors. Cell death (%) in primary cultures of rat cortical neurons was determined by measuring LDH release 48 h after OGD. Cultures were incubated with (A) 8 or 1a each at 0.1, 0.3, 1, 3 or 10 μM; (B) FK228 (at 0.1, 1 or 10 μM), MS-275 (at 0.3, 1, 10 μM), 1a (at 0.3 μM) and 8 (at 3 μM); (C) 9, 10, 11 (each at 1, 3 or 10 μM), 1a (at 0.3 μM) and 8 (at 3 μM), under the conditions noted in the section of Materials and Methods. Each value is the mean ± standard error mean of triplicate measurements. The asterisk denotes a significant difference (*p < 0.05) versus the control (0.1% DMSO).
