Supplementary MaterialsData_Sheet_1. neural stem cell (NSC) differentiation through reduced SOX2 (marker of multipotency) and improved III-tubulin (marker of neural differentiation) which suggests a great potential like a non-toxic inducer of cell differentiation. More importantly, in glioma malignancy cells (GL-261), compound 1a reduced stemness, by reducing SOX2 protein levels, while also advertising chemotherapy sensitization. These results focus on the potential of p53 modulators for mind cell differentiation, with spirooxindole 1a representing a encouraging lead molecule for the development of new mind antitumor medicines. = 9Hz, 1H, ArH), 4.45 (s, 1H, H-4), 1.18 (s, 9H, C(CH3)3); 13C NMR (75 MHz, CDCl3) (ppm): 177.5 (C=O), 161.9 (C=N), 155.7 (d, = 243 Hz), 145.5 (Cq), 138.1 (Cq), 136.6 (Cq), 134.6 (Cq), 129.0 (CH), 128.7 (CH), 121.9 (d, = 19.5 Hz), 116.3 (Cq), 115.4 (d, = 24,75 Hz), 111.9 (CH), 77.3 (Cspiro), 62.5 (CH-4), 34.9 (C(CH3)3), 29.4 (C(CH3)3) (Supplementary Datasheet 1); MS (ESI+) m/z calcd for Caudatin C26H23ClFN3O: 447, found out 448 [M + H]+. 5-(tert-butyl)-6-chloro-2-(4-chlorophenyl)-5-fluoro-4-phenyl-2,4-dihydrospiro[indoline-3,3-pyrazol]-2-one (1b) Following a general process, to a solution of Caudatin 2a (30 mg, 0.09 mmol) in CH2Cl2 (10 ml) was added 3b (1.2 eq) and triethylamine (3 eq).
