漆树酸-CAS 16611-84-0-Calbiochem

A cell-permeable ginkgolic acid (Cat. No. 345887) analog that inhibits protein SUMO (Cat. Nos. 662037, 662039, and 662042) modification (IC₅₀ = 2.2 µM using RanGAP1-C2 as substrate) in an ATP-dependent manner by selectively targeting SUMO-activating enzyme E1 (Cat. Nos. 662073 and 662074) and interfering with E1-SUMO intermediate formation. Both anacardic acid and ginkgolic acid are shown to effectively decrease overall SUMOylation of 293T cellular proteins in a dose-dependent manner, while neither compound is effective in affecting overall cellular protein ubiquitination or histone H4K8 acetylation in 293T cultures, although anacardic acid is shown to inhibit p300 (Cat. No. 506200) and PCAF (Cat. No. 124026) histone acetyltransferase activities in cell-free acetylase assays (by 82% and 86%, respectively, at 10 µM). Also reported to inhibit the activity of prostaglandin synthase, tyrosinase, and lipoxygenase, as well as to enhance Aurora kinase A (Cat. No. 481413), but not Aurora kinase B, autophosphorylation and kinase activity by inducing conformation change and enhancing ATP binding.
