Synonyms: GTP-d14 dilithium
Guanosine triphosphate-d14 dilithium (GTP-d14 dilithium) is the deuterated-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 .

Research Areas:  

Others

2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

9,363 compounds

Cysteine proteases (CPs), a key enzyme family regulating physiological metabolism and mediating pathological processes (such as abnormal bone resorption, tumour invasion, and pathogen infection), represent a core therapeutic target for developing specific inhibitors in disease intervention. Currently reported CP inhibitors primarily achieve their inhibitory function by precisely binding to CP active pockets (e.g., S1-S4 non-primed regions or S1'-S2' primed regions) and forming covalent/non-covalent interactions with the active site cysteine residues, providing clear structural references for the development of novel inhibitors.

This compound library, designed based on the core strategy of "similarity-based known active structures", contains over 200 cysteine protease inhibitors. Leveraging AI-driven molecular screening technology, it retains the critical pharmacological and shape features of reported CP inhibitors, serving as a specialized tool for efficiently discovering novel cysteine protease inhibitors.

Nucleoside and nucleotide analogues are synthetic, chemically modified compounds that have been developed to mimic their physiological counterparts in order to exploit cellular metabolism and subsequently be incorporated into DNA and RNA to inhibit cellular division and viral replication. In addition to their incorporation into nucleic acids, nucleoside and nucleotide analogues can interact with and inhibit essential enzymes such as human and viral polymerases (that is, DNA-dependent DNA polymerases, RNA-dependent DNA polymerases or RNA-dependent RNA polymerases), kinases, ribonucleotide reductase, DNA methyltransferases, purine and pyrimidine nucleoside phosphorylase and thymidylate synthase. These actions of nucleoside and nucleotide analogues have potential therapeutic benefits — for example, in the inhibition of cancer cell growth, the inhibition of viral replication as well as other indications.

908 compounds

The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. Hormones are chemicals that serve to communicate between organs and tissues for physiological regulation and behavioral activities. Hormones affect distant cells by binding to specific receptor proteins in the target cell, resulting in a change in cell function.

The endocrine system is concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Irregulated hormone release, inappropriate response to signaling or lack of a gland can lead to endocrine disease.

MCE offers a unique collection of 908 endocrinology related compounds targeting varieties of hormone receptors such as thyroid hormone receptor, TSH receptor, GNRH receptor, adrenergic receptor, etc. MCE Endocrinology Compound Library is a useful tool for the discovery of endocrinology drugs.

Extracellular vesicles (EVs) are small membrane binding structures that are released from cells into the surrounding environment and play a crucial role in mediating and regulating intercellular communication related to physiological and pathological processes. EVs are lipid membrane vesicles composed of proteins, lipids, and nucleic acids. EVs can be divided into several types based on their source, such as extracellular vesicles, microcapsules, and apoptotic vesicles. The size range of exosomes is 30-150nm, which are endocrine in multi vesicular endosomes (MVEs); microvesicles (50-1000nm) are secreted directly through extracellular interactions, thereby releasing plasma membrane vesicles. In contrast, apoptotic bodies are usually larger, ranging in size from 1 to 5 μ m. This is generated during programmed cell death. EV plays a crucial role in transmitting information between cells and influencing the behavior and function of receptor cells.

MCE designs a unique collection of 707 small molecules related to extracellular vesicles (EVs). It is a good tool to be used for research on metabolize, cancer and other diseases.

Obesity is widely recognized as the largest and fastest growing public health problem and is associated with numerous chronic disorders including osteoarthritis, obstructive sleep apnea, gallstones, fatty liver disease, reproductive and gastrointestinal cancers, dyslipidemia, hypertension, type 2 diabetes, heart failure, coronary artery disease, stroke, etc. Although obesity has long been associated with serious health issues, it has only recently been regarded as a disease in the sense of being a specific target for medical therapy. Obesity may be viewed as the dysregulation of two physiological functions, appetite regulation and energy metabolism, which combine to create disordered energy balance. Consequently, developing obesity treatments that target novel pathways is a growing focus for both biopharmaceutical industries.

MCE Anti-Obesity Compound Library owns a unique collection of 3,741 compounds, which mainly target signaling pathway of controlling appetite, fatty acid metabolism and energy expenditure, etc. This library is a useful tool for discovery anti-obesity drugs.
