tubulin inhibitor 8

Tubulin inhibitor 8是管蛋白和多种癌症细胞系的抑制剂，对管蛋白聚合和K562细胞生长具有抑制作用 ，IC50分别为0.73μM 和14nM。

CKI-7 是一种有效且 ATP 竞争性的酪蛋白激酶 1 抑制剂，IC50为 6 μM，Ki 为 8.5 μM。它选择性抑制 Cdc7激酶，还抑制 SGK，S6K1以及 MSK1。

EN219 is a synthetic recruiter of the E3 ubiquitin ligase RNF114.1It binds to cysteine 8 (C8) in the intrinsically disordered region of RNF114 (RNF114-C8; IC50= 470 nM) and inhibits RNF114-induced autoubiquitination and p21 ubiquitination in a cell-free assay when used at a concentration of 50 μM. EN219 (1 μM) also interacts with cysteine residues in the tubulin β1 chain (TUBB1), heat shock protein 60 (Hsp60), also known as Hsp family D member 1 (HspD1), and histone H3.1 (HIST1H3A) in 231MFP human breast cancer cells in a proteomic profiling assay. It has been linked to the bromodomain and extra terminal domain (BET) inhibitor ligand (+)-JQ1 for use as a proteolysis-targeting chimera (PROTAC) to degrade bromodomain-containing protein 4 (BRD4) in 231MFP cells. 1.Luo, M., Spradlin, J.N., Boike, L., et al.Chemoproteomics-enabled discovery of covalent RNF114-based degraders that mimic natural product functionCell Chem.
