507 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 507 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.

Synonyms: 8-Oxo-Deoxyguanosine triphosphate
8-Oxo-dGTP (8-Oxo-Deoxyguanosine triphosphate) is an oxidized guanine nucleotide formed by ROS-mediated oxidative modification of dGTP, and it also serves as a key substrate for 8-oxo-dGTP pyrophosphohydrolases (such as hMTH1 and E. coli MutT). 8-Oxo-dGTP acts as a DNA mutagen, inserts into nascent DNA and pairs with adenine and cytosine, inducing A:T to C:G transversion mutations. Furthermore, 8-Oxo-dGTP causes oxidative DNA base modification, strand breakage and S-phase arrest, and ultimately triggers AIF-mediated apoptosis and promotes spontaneous carcinogenesis in mth1-deficient mice. Accumulation of 8-Oxo-dGTP in cells induces genomic instability, but it exhibits a tumor-suppressive effect that reduces tumor incidence in mouse models instead. 8-Oxo-dGTP is widely used in studies related to spontaneous carcinogenesis, Parkinson's disease, Alzheimer's disease, heart failure and tumor mechanisms .
