Figure Lengend Snippet: Glutamic acid derivatives potentiation on G551D-CFTR. (a) FLIPR channel function studies of WT-CFTR (blue trace) and G551D-CFTR (gray trace) stimulated with 10 μM cAMP agonist, forskolin (FSK), and then inhibited with 10 μM CFTRinh-172. Averaged traces ( n = 3) of response of G551D-CFTR to chronic treatment of 1 μM 1 (black trace), and glutamic acid derivatives of 1 : 2 (orange trace), 3 (green trace), and 4 (red trace). (b) Quantification of the maximum peak of FSK stimulation in the FLIPR assay relative to the baseline shows that acute treatment with 1 μM 1–4 shows significantly potentiated CFTR chloride flux compared to 10 μM FSK alone ( n = 3 for all conditions). Results are presented as mean ± SD and analyzed by one-way ANOVA and Dunnett’s post hoc test (** P < 0.02; *** P < 0.0002; **** P < 0.0001 compared with 10 μM FSK).
