Cat. No.: HY-113225S1
Synonyms: GTP-13C10,15N5 tetraammonium
Guanosine triphosphate- 13C10, 15N5 tetraammonium solution (100 mM) (GTP- 13C10, 15N5 tetraammonium) is the 15N, 13C-labeled Guanosine triphosphate (HY-113225). Guanosine triphosphate (GTP) is a critical nucleotide and regulator of cellular metabolism. Guanosine triphosphate promotes ribosomal DNA localization, pre-rRNA transcription and ribosome biogenesis by binding to RNA polymerase I and GPN proteins (GPN1/3). Guanosine triphosphate links MYC-dependent ribosome biogenesis to nucleotide sufficiency, acts as a metabolic gatekeeper supporting protein synthesis, DNA/RNA synthesis and cellular signal transduction, while also participating in the physiological activities of pancreatic β-cells and serving as an oxidative substrate for reactive oxygen species. In small cell lung cancer with high MYC expression, Guanosine triphosphate accumulates through the IMPDH-driven synthetic pathway, thereby affecting apoptosis and mitotic processes. Guanosine triphosphate is used in the research of small cell lung cancer, hepatoblastoma and cellular metabolism .

Tempone serves as a substrate for intracellular reduction to hydroxylamine, rapidly equilibrates between intracellular and extracellular compartments, reduces nitroxide radical spin labels at the ubiquinol site of the respiratory chain, and acts as an alternative terminal electron acceptor when electron flow to oxygen is blocked. Tempone serves as a superoxide sensor, a T2-weighted MRI contrast agent, and a dynamic nuclear polarization polarizing agent for 13C. Tempone inhibits superoxide and peroxynitrite, hydroxyl radical generation, nitrotyrosine formation, and poly (ADP-ribose) formation, and alleviates renal dysfunction and injury in ischemia/reperfusion and hydrogen peroxide-induced injury.

Ibetazol is a Importin β1 (KPNB1) inhibitor and nucleocytoplasmic transport disruptor. Ibetazol binds covalently to Cys585 of Importin β1, blocks both Importin β1-mediated direct transport and Importin α-dependent nuclear import processes, without affecting transport mediated by other nucleocytoplasmic transport proteins. Ibetazol induces cytoplasmic accumulation of Importin α1, and inhibits nuclear import of substrates carrying nuclear localization signals (NLS), including the NLS-cMyc reporter gene, RelA/p65 and SREBP1. Ibetazol triggers spindle malformation and chromosome misalignment by disrupting the mitotic function of Importin β1. Ibetazol inhibits the proliferation of cells expressing wild-type Importin β1. Ibetazol has a high activity-cytotoxicity window, lacks intrinsic fluorescence, and acts rapidly on nucleocytoplasmic transport processes. Ibetazol serves as a tool compound for investigating nuclear import processes specifically mediated by Importin β1 .

Cancer

YL064 is a multi-target STAT3-c-MYC inhibitor that directly binds to ATXN3 and inhibits its deubiquitinating activity, thereby promoting the ubiquitination and proteasomal degradation of oncogenic substrates of ATXN3. YL064 inhibits the phosphorylation of STAT3-Tyr705 without altering the total protein level of STAT3; meanwhile, it directly binds to the SH2 domain of STAT3 to block the dimerization, nuclear translocation, and DNA-binding activity of STAT3. YL064 directly targets the C-terminal HLH-Zip domain of c-Myc, upregulates the phosphorylation of c-Myc at the Thr58 site, and induces the ubiquitination and proteasome-dependent degradation of c-Myc. YL064 suppresses tumor cell proliferation, induces G2/M cell cycle arrest, reduces cell migration and invasion capacities, and triggers cancer cell apoptosis. YL064 can be used in related research on breast cancer, prostate cancer, diffuse large B-cell lymphoma, and multiple myeloma .

Protein phosphorylation is a key post-translational modification underlying the regulation of many cellular processes. Phosphatases and kinases contribute to the regulation of protein phosphorylation homeostasis in the cell. This reversible regulation of protein phosphorylation is critical for the proper control of a wide range of cellular activities, including cell cycle, proliferation and differentiation, metabolism, cell-cell interactions, etc.

Protein phosphatases have evolved in separate families that are structurally and mechanistically distinct. Based on substrate specificity and functional diversity, protein phosphatases are classified into two superfamilies: Protein serine/threonine phosphatases and Protein tyrosine phosphatases. Ser/Thr phosphatases are metalloenzymes belonging to two major gene families termed PPP (phosphoprotein phosphatase) and PPM (metal-dependent protein phosphatases), whereas protein tyrosine phosphatases (PTPs) belong to distinct classes of enzymes that utilize a phospho-cysteine enzyme intermediate as a part of their catalytic action.

MCE supplies a unique collection of 185 phosphatase inhibitors that mainly targeting protein tyrosine phosphatases (PTPs) and serine/threonine-specific protein phosphatases. MCE Phosphatase Inhibitor Library is a useful tool for phosphatase drug discovery and related research.

8-Oxo-dGTP (8-Oxo-Deoxyguanosine triphosphate) trisodium solution (100mM) 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 trisodium solution (100mM) 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 trisodium solution (100mM) 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 trisodium solution (100mM) in cells induces genomic instability, but it exhibits a tumor-suppressive effect that reduces tumor incidence in mouse models instead. 8-Oxo-dGTP trisodium solution (100mM) is widely used in studies related to spontaneous carcinogenesis, Parkinson's disease, Alzheimer's disease, heart failure and tumor mechanisms .
