MedChemExpress parp1 protacs sk 575
A) Structure <t>of</t> <t>SK-575</t> PROTAC formed by the PARPi Olaparib linked to Thalidomide, a CRBN binder. B) Western blot analysis of <t>PARP1</t> expression in isogenic CRBN WT and KO KBM7 cells treated with 100 nM SK-575 or Thalidomide for 48h. ACTB was used as loading control. C) Viability assay by MTT performed in CRBN WT or KO KBM7 cells pre-treated with 100 nM SK-575 for 24 h followed by a treatment with both SK-575 and the indicated doses of Olaparib or Talazoparib for another 24 h. Data are normalized to vehicle or SK-575 pre-treated cells and correspond to three biological replicates. IC50s were calculated with non-linear regression analysis and are shown in the figure (µM). Statistical significance was determined with Extra sum-of-squares F test. D) Analysis of percentage of viability as assessed by Annexin V/PI staining using flow cytometry analysis from three biological replicates. Statistical significance was determined with Ordinary one-way ANOVA and Tukey’s multiple comparisons test. E) Representative images of the Annexin V/PI staining. Percentage of cells for each population are shown. F) Western blot showing PARP1 degradation in human bone marrow mononuclear cells treated with 100 nM SK-575 for 48 h. G) Colony-forming cells (CFC) assay of human bone marrow mononuclear cells pre-treated with 100 nM SK-575 24 h before seeding them in MethoCult semi-solid methylcellulose-based media with the indicated doses of Talazoparib with or without 100 nM SK-575. Colonies were quantified after 14 days. Error bars indicate mean ± s.d. (n = 3). Statistical significance was determined with unpaired t-tests. In all the figures * = p < 0.05, and *** = p < 0.001.
