Mito-RhFe is a Fluorescent probe for mitochondrial labile Fe³⁺ monitoring via imaging and flow cytometry. This probe is a rhodamine-based construct with a spirolactam fluorescence signaling group and an N2-hydroxyethyldiethylenetriamine chelator; its delocalized positive charge enables mitochondria-targeting ability in live cells, and it exhibits fine cell membrane permeability. In its native state, it exists in the non-fluorescent spirolactam form, but upon binding to Fe³⁺, it undergoes a ring-opening conversion to the fluorescent rhodamine form, triggering a turn-on fluorescent response; this process is reversible, as the addition of the metal chelator TPEN removes Fe³⁺ and converts the probe back to its non-fluorescent spirolactam form, and re-addition of Fe³⁺ restores fluorescence. The probe shows high selectivity for Fe³⁺ over most other metal cations present in living systems, with a ~90-fold fluorescence enhancement upon binding to 20 equiv of Fe³⁺. Mito-RhFe has excitation/emission wavelengths of Ex/Em = 540/578 nm, with an ~8 nm bathochromic shift in emission upon Fe³⁺ binding, and it can also be excited at 543 nm for confocal imaging with emission detected at 570-620 nm[1].

NRLD is a lipid droplet-targeting solvatochromic fluorescent probe developed based on Nile Red (HY-D0718), which can target lipid droplets and sense the non-polar lipid microenvironment inside lipid droplets. NRLD exhibits superior lipid droplet-targeting selectivity compared to the parent Nile Red dye in HeLa cell imaging. NRLD achieves detection relying on the solvatochromic effect generated by excited-state charge transfer, and its emission wavelength shifts according to the local polarity changes of the microenvironment it locates in: the more compact and ordered the lipid packing and the lower the environmental polarity, the more blue-shifted the emission; the looser the lipid packing or the stronger the hydration and the higher the environmental polarity, the more red-shifted the emission. NRLD shows blue shift in the non-polar oil core of lipid droplets and red shift in high-polarity environments such as phosphate buffer .

The TCA cycle (tricarboxylic acid cycle)—is also known as the Krebs cycle or the citric acid cycle (CAC). The TCA cycle is a series of chemical reactions that release stored energy through the oxidation of acetyl-CoA in carbohydrates, fats, and proteins.

For decades, the TCA cycle has been considered as the central pathway for cell oxidative phosphorylation to produce energy and biosynthesis. Research shows that TCA cycle is associated with many diseases, especially cancer. In colon carcinoma, liver cancer and other cancers, there are mutations that lead to the imbalance of TCA cycle metabolites, indicating that TCA cycle may be related to the occurrence of cancer. Understanding the role and molecular mechanism of TCA cycle in inhibiting or promoting cancer progression will promote the development of new metabolite-based cancer treatment methods in the future.

MCE supplies a unique collection of 25 key intermediates of the TCA cycle, which can be utilized for TCA-related research and metabolomics identification studies.

Metabolomics is the large-scale study of cellular metabolic complement, with proven utility in both basic and applied studies of plants, microorganisms, and mammals. As an important tool for the study of complex biological systems, metabolomics monitors the complex molecular networks that exist in the natural flow of information from genes to mRNA and proteins to organisms. The metabolome is composed of biomolecules that most closely resemble the phenotype of an organism, and changes in its composition can easily lead to the production of diseases. Therefore, metabolomics has received much attention in drug target discovery, drug response and translational research of disease mechanisms. Mass spectrometry-based metabolomics methods can simultaneously detect and quantify thousands of metabolite signatures, thereby characterizing the pathophysiological mechanisms of various biomedical symptoms.

MCE can provide 661 mass spectrometry human endogenous metabolites that can be used for metabolite identification and quantification, functional cell detection and phenotypic screening of mass spectrometry.

In the research of covalent inhibitors targeting serine and threonine, scientists have found that the nucleophilicity of these hydroxyl groups is significantly enhanced due to the influence of their surrounding environment. This results in higher activity during catalytic reactions. Aspirin, which targets the non-catalytic domain serine (Ser529 in human COX1) of cyclooxygenase, exerts its anti-inflammatory effect through covalent binding. β-lactam antibiotics, which targets the catalytic domain serine of penicillin-binding proteins, interferes with bacterial cell wall synthesis.

Through careful selection, we constructed a structural filter containing over 110 electrophilic groups. By analyzing the electrophilic fragments selected by the structural filter, we removed any molecules with trivial or undesirable structural features. Ultimately, we obtained 3,300 fragment molecules which can target serine and threonine residues and can be used for fragment-based covalent drug discovery.

MitoAIE1 is a Fluorescent probe for mitochondrial viscosity detection. MitoAIE1 contains a pyridinium structural unit, which endows it with mitochondria-targeting specificity. The detection mechanism of this probe is based on aggregation-induced emission (AIE): in low-viscosity media such as PBS buffer, intramolecular rotation leads to non-radiative energy dissipation, resulting in only weak fluorescence; however, in high-viscosity environments such as the mitochondrial matrix or the vicinity of the inner mitochondrial membrane, such intramolecular motion is restricted, thereby significantly enhancing its fluorescent signal; in addition, this probe is not interfered by changes in microenvironment polarity and pH. Its emission wavelength is 625 nm, with absorption peaks at 325 nm and 450 nm; when transferred from low-viscosity PBS to high-viscosity 99% glycerol, its fluorescence intensity at 625 nm can be increased by 38-fold. It can be used to monitor changes in mitochondrial viscosity during processes such as Stauroporine (HY-15141)-induced apoptosis and starvation-induced mitophagy in live cells, and has good biocompatibility .

Apoptosis

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 .

Mito-laurdan (bromide) is a Fluorescent dye for mitochondrial membrane fluidity and packing measurement. It depends on membrane potential for targeting: it contains a cationic triphenylphosphonium moiety that accumulates at the inner mitochondrial membrane due to the membrane's negative potential, connected via a 3-carbon linker. As a solvatochromic dye derived from Laurdan (HY-D0080), it retains the characteristic mechanism where fluorescence emission shifts based on membrane packing: in more fluid, loosely packed membranes, greater water penetration leads to increased dipolar relaxation and a bathochromic red shift in emission, while more ordered membranes show a blue-shifted emission; these shifts are quantified using generalized polarization, calculated from emission intensities in ordered and disordered spectral windows. Its excitation wavelength is 352 nm, with emission detected in ordered (409-463 nm) and disordered (473-516 nm) spectral windows. It localizes specifically to mitochondria in HeLa cells, showing high signal overlap with MitoTracker Deep Red, and can detect changes in inner mitochondrial membrane fluidity .

Carbohydrate metabolism serves as a central hub for energy supply and biosynthesis in living organisms and plays a critical role in the onset and progression of various diseases. In recent years, studies have shown that tumor cells reprogram their energy metabolism through aerobic glycolysis (the Warburg effect) to support rapid proliferation. Immune cells also rely on specific carbohydrate metabolic pathways to regulate their activation and differentiation states, while disorders such as diabetes and metabolic syndrome arise directly from dysregulation of carbohydrate metabolism. In addition, enzymes and key metabolic nodes involved in carbohydrate metabolism have become important targets for drug discovery, and therapeutic strategies targeting glycolysis, the pentose phosphate pathway, and energy metabolism are continuously advancing the treatment of cancer and metabolic diseases. Therefore, systematic analysis of carbohydrate metabolic networks and their associated metabolites is of great significance for elucidating disease mechanisms and developing novel therapeutic approaches.

The MCE Carbohydrate Metabolism Metabolite Library is constructed based on classical carbohydrate metabolic pathways and contains 76 metabolites. It systematically integrates key metabolic networks, including glycolysis, the pentose phosphate pathway, the tricarboxylic acid (TCA) cycle, monosaccharide metabolism, and sugar acid interconversions. The library comprehensively covers core metabolic nodes from glucose uptake and utilization to energy production and biosynthesis, while also incorporating important upstream and downstream intermediates. It enables accurate representation of intracellular metabolic flux dynamics and is well suited for applications such as metabolic flux analysis, target validation, and mechanistic studies. Furthermore, it provides robust support for multi-omics integration and the development of precision intervention strategies.
