D-α-Tocopherol acetate has been evaluated for various bioactivities across multiple assays. It was tested for antiproliferative activity against the human breast cancer cell line MCF-7 using the MTT assay and demonstrated an IC50 value greater than 500,000 nM, indicating limited effectiveness in this context. Additionally, it inhibits GCN5L2, induces DNA re-replication in colon adenocarcinoma cells, and blocks Ebola virus entry through multiple mechanisms, showing potency in the nanomolar to micromolar range. D-α-Tocopherol acetate also protects against IL1-beta-induced cell damage in NHEK cells by inhibiting PGE2 production at concentrations of 0.1 µM, 0.5 µM, and 2 µM, with respective inhibitions of 38.0%, 40.0%, and 67.0%. It further shows a protective effect against t-BHP-induced cell damage with 77.4% inhibition and against H2O2-induced cell damage with 25.0% inhibition at 2 µM after 24 hours. In mouse N18TG2 cells, the compound undergoes complete degradation, leading to 100.0% alpha-TOH formation after 24 hours. Moreover, it weakly inhibits the bovine mitochondrial electron transport protein complex 2 succinate: DCPIP oxidoreductase activity with an IC50 value higher than 1,000,000 nM. D-α-Tocopherol acetate also acts as a SARS-CoV-2 3CL-Pro protease inhibitor, showing 30.78% inhibition at 20 µM. Despite this, it exhibits minimal antiviral activity against SARS-CoV-2 with a 0.17% inhibition rate in VERO-6 cells at 10 µM after 48 hours. While demonstrating moderate inhibitory activity against PDE3A and PDE4A with AC50 values of 932.7 nM and 9,379.5 nM, respectively, its binding affinity and bioactivity concerning various receptors and enzymes generally remain low, with AC50 values exceeding 30,000 nM..
