- Abstract
Additional file 1: Scheme S1. Synthesis of Probe HBAE. Figure S1. UV-Vis spectrum and of fluorescent spectrum of HBAE in DMSO. Figure S2. Particle size of HBAE by dynamic light scattering. Average size=133.4 nm. Figure S3. TEM image of HBAE at pH=7.4. Figure S4. Fluorescence intensity of HBAE (10 μM) at 650 nm versus the different cells membranes protein. a. U87-MG cell membranes protein, b. N2a cell membranes protein, c. Bend.3 cell membranes protein, d.U251 cell membranes protein. The excitation wavelength was 560 nm. Figure S5. Fluorescence intensity of HBAE (10 μM) at 650 nm versus the different cells membranes protein. a. U87-MG cell membranes protein, b. N2a cell membranes protein, c. Bend.3 cell membranes protein, d. HEK293 cell membranes protein. Figure S6. CCK8 of the cell viability of HBAE. (Each sample was tested using three replicates, and the results are reported as the mean ± standard deviation). Figure S7. Western blot images of BACE1 in 4 cell lines. Figure S8. Supplementary information establishment of blood-brain barrier in vitro. Figure S9. Gene banding of AD and wild-type mice model. 1, 2, 3 and 6 belong to AD model mice, and 4, 5, 7 and 8 belong to wild-type mice. Figure S10. Test of hemolysis activity of formulations. (A) Photos of hemolysis after incubation with different formulations. HBAE of different concentrations are 12.5, 25, 50, 100, 200, 400 μ g/mL, respectively. Figure S11. H&E staining of heart, liver, spleen, lung, kidney tissues of C57 BL/6 mice after HBAE treatment, scale bar = 200 μm. Figure S12. Analysis of serum levels of ALT, AST, BUN and Cr in tumor-bearing mice after HBAE treatment. Data were mean ± SD (n = 5). Figure S13. The H&E staining of the AD mice brain after HBAE treatment. Figure S14. 1H NMR (500 MHz, DMSO-d6) of HBAE. Figure S15. 13C NMR (125 MHz, DMSO-d6) of HBAE. Figure S16. MS spectra of HBAE.
