Tubulin/NEDDylation-IN-1	Microtubule/Tubulin	Cancer
Tubulin/NEDDylation-IN-1 (compound C11) is a dual inhibitor of tubulin (Microtubule/Tubulin)-NEDDylation (IC₅₀ for tubulin=2.40 μM), which has strong anti-proliferative activity. Neddylation is a protein post-translational modification that covalently tags the ubiquitin-like protein NEDD8 to target proteins. Tubulin/NEDDylation-IN-1 forms hydrogen bonds with residues of tubulin and E1 NEDD8 activating enzyme (NAE) through methoxy and dithiocarbamate groups and inhibits NEDDylation and microtubulin in an ATP-dependent manner. tube polymerization .

Ubiquitination Compound Library	257 compounds
Protein ubiquitination is an enzymatic post-translational modification in which an ubiquitin protein is attached to a substrate protein. Ubiquitination involves three main steps: activation, conjugation, and ligation, performed by ubiquitin-activating enzymes (E1s), ubiquitin-conjugating enzymes (E2s), and ubiquitin ligases (E3s), respectively. Ubiquitination affects cellular processes such as apoptosis, cell cycle, DNA damage repair, and membrane transportation, etc. by regulating the degradation of proteins (via the proteasome and lysosome), altering the cellular localization of proteins, affecting proteins activity, and promoting or preventing protein-protein interactions. Deregulation of ubiquitin pathway leads to many diseases such as neurodegeneration, cancer, infection and immunity, etc. MCE offers a unique collection of 257 small molecule modulators with biological activity used for ubiquitination research. Compounds in this library target the key enzymes in ubiquitin pathway. MCE Ubiquitination Compound Library is a useful tool for the research of ubiquitination regulation and the corresponding diseases.
