tubulin inhibitor 8

Tubulin inhibitor 8 is an inhibitor of tubulin and various cancer cell lines and inhibits tubulin polymerisation and K562 cell growth with an IC50 of 0.73 μM and 14 nM respectively.

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.

Tubulin polymerization-IN-8 (compound IIc) is a potent inhibitor of tubulin polymerization, inducing concentration-dependent cell cycle arrest at the G2 M phase in HCT116 tumor cells and significantly inhibiting tubulin polymerization with an IC50 of 12.7 μM, showing potential for cancer research [1].

Tubulin HDAC-IN-3 (compound 12a) is a potent dual inhibitor of tubulin polymerization and HDAC1 8, with IC50 values of 5.4 μM for tubulin polymerization, and 0.155 and 0.177 μM for HDAC1 and HDAC8, respectively. It obstructs the cell cycle, triggers apoptosis, and suppresses colony formation [1].

Colchicine-d6 is a deuterated compound of Colchicine. Colchicine has a CAS number of 64-86-8. Colchicine is a tubulin inhibitor (IC50: 3 nM) and blocks polymerization of microtubules by binding to tubulin.
