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].

JF635-HTL is a Fluorescent dye for spatiotemporally controlled live cell imaging and single-molecule localization microscopy SMLM. Its detection mechanism depends on the conformational change of a photoswitchable HaloTag psHaloTag, which integrates the light-responsive AsLOV2 domain: in the dark state, the folded Jα helix of AsLOV2 maintains the dye in a predominantly closed, non-fluorescent form; upon 450 nm illumination, a metastable photo-adduct forms between a cysteine side chain and the FMN cofactor of AsLOV2, causing undocking and unfolding of the Jα helix, which propagates a conformational change to the HaloTag near the dye binding site, shifting the dye's equilibrium to the open, fluorescent form; this process is fully reversible in the dark as the Jα helix refolds spontaneously, returning the dye to the closed, non-fluorescent state. For psHaloTag1a labeled with JF635-HTL, the excitation/emission wavelengths for the ON state are Ex/Em = 642/655 nm, while for psHaloTag1b labeled with JF635-HTL, the wavelengths are Ex/Em = 639/655 nm; when bound to wild-type HaloTag, the wavelengths are Ex/Em = 640/656 nm .

Research has shown that drugs targeting aging pathways demonstrate promising potential in models of age-related diseases such as Alzheimer's disease, cardiovascular diseases, metabolic syndrome, osteoarthritis, and various malignancies. This suggests that intervening in the biological processes of aging may enable synergistic prevention and treatment of multiple chronic diseases. Against the backdrop of the gradual elucidation of core aging mechanisms-including cellular senescence, telomere attrition, epigenetic dysregulation, and chronic inflammation anti-aging research has shifted from traditional phenotypic interventions toward targeting key pathways that regulate biological age.
The MCE Anti-Aging Compound Library Mini is precisely built upon this cutting-edge concept. It focuses on aging-related targets validated through genetic or functional studies, comprising 381 compounds designed to provide systematic research tools for aging biology and intervention strategy development. The library covers core mechanisms such as mTOR, SIRT, energy metabolism, clearance of senescent cells, optimization of mitochondrial function, and telomere maintenance. For each target, 1-5 compounds with clear activity and strong representativeness have been carefully selected, spanning the entire translational spectrum from preclinical tool molecules to clinically investigational drugs.

Lactic acid metabolism is one of the key metabolic pathways within living organisms. It plays a crucial role not only in cellular energy conversion but is also closely related to a variety of physiological and pathological processes. The production and clearance of lactic acid are important indicators of cellular metabolic balance, and its abnormal regulation may lead to conditions such as lactic acidosis, muscle fatigue, and hereditary metabolic diseases. Moreover, lactic acid is closely related to the malignancy of tumors and is considered a biomarker for malignant tumors and poor prognosis. Lactic acid can serve as a metabolic substrate to support the metabolic needs of tumor cells under hypoxic conditions, and it can also cause acidification of the tumor microenvironment, suppress immune cell function to promote immune evasion, and induce drug resistance in tumor cells. Currently, targeting lactic acid-lactylation and its related metabolic pathways has become a new research avenue for cancer treatment. In-depth exploration of the molecular mechanisms of lactic acid metabolism can help in screening lead compounds that regulate the lactic acid metabolism.
MCE contains 582 small molecule compounds targeting enzymes involved in lactic acid metabolism. This library is of significant value for researching the role of lactate metabolism in the mechanisms of diseases.

Ionizable lipids are a class of specialized, functional lipid molecules with pH-sensitive charge characteristics. They are primarily divided into two major categories: ionizable cationic lipids and ionizable anionic lipids, though the term typically specifies ionizable cationic lipids within the biomedical field. Structurally, these lipids consist of an ionizable hydrophilic headgroup, a biodegradable linker, and hydrophobic tails. Their primary application is serving as the key delivery vehicle in lipid nanoparticles (LNPs) to encapsulate negatively charged nucleic acid macromolecules, such as mRNA vaccines, siRNA therapeutics, and CRISPR gene-editing components. In a physiological, neutral environment, they remain electrically neutral to minimize systemic toxicity and prolong circulation time. Upon entering the acidic microenvironment of cellular endosomes, however, they undergo protonation to become positively charged, thereby inducing membrane fusion and enabling the highly efficient intracellular release of the nucleic acid cargo. Consequently, they serve as the technological cornerstone for bringing nucleic acid therapies into clinical application.
To accelerate the translational process of cutting-edge nucleic acid drugs, MCE has meticulously constructed an ionizable lipid compound library containing 93 high-performance molecules, aiming to provide researchers and pharmaceutical professionals with a high-throughput, multi-dimensional lipid screening platform.

PH11 is a novel focal adhesion kinase (FAK) inhibitor that rapidly induces apoptosis in TRAIL-resistant PANC-1 cells when combined with TRAIL, but has no effect on normal human fibroblasts. The study found that PH11 downregulates c-FLIP through inhibition of FAK and phosphatidylinositol-3-kinase (PI3K)/AKT pathways, thereby restoring the TRAIL apoptotic pathway, suggesting that this combination therapy may provide an attractive therapeutic strategy for the safe and effective treatment of pancreatic cancer. PH11 selectively inhibits c-FLIP expression by modulating upstream signaling pathways and may represent an innovative therapeutic strategy. Although further work is needed to fully elucidate the mechanism of PH11-induced TRAIL sensitization, we believe that our results will provide a new approach to target c-FLIP without the risk of interfering with caspase-8 processing, which could potentially lead to TRAIL resistance. This study also suggests a role for the FAK/AKT signaling pathway in regulating c-FLIP expression in TRAIL-induced apoptosis, and this understanding will provide important clues to control the resistance mechanism to optimize the potential of TRAIL-based pancreatic cancer treatment.

Kinases is a class of enzymes that adds chemicals called phosphates to other molecules, such as sugars or proteins. Protein phosphorylation serves as a critical regulatory mechanism for numerous cellular processes including cell division, metabolism, and signal transduction, with approximately 50% of cellular functions in humans being regulated by kinase activity. In drug discovery, kinases represent a major category of therapeutic targets, and kinase inhibitors constitute an important class of pharmaceuticals that block the activity of specific disease-associated enzymes, particularly in cancer and inflammatory disorders. Small molecule kinase inhibitors represent one of the fastest-growing drug categories, having received U.S. Food and Drug Administration (FDA) approval for both oncological and non-oncological indications. As of September 2023, over 70 FDA-approved small molecule kinase inhibitors are commercially available.
The MCE Kinase Inhibitor Library Mini contains 270 kinase inhibitors primarily targeting protein kinases (VEGFR, EGFR, BTK, CDK, Akt, etc.), lipid kinases (PI3K, PI4K, SK, etc.), and carbohydrate kinases. This collection includes 1-3 highly specific representative compounds per target, optimized for screening of kinase-related drug targets in pharmaceutical research.

Protein protein interactions (PPI) have pivotal roles in life processes. The studies showed that aberrant PPI are associated with various diseases, including cancer, infectious diseases, and neurodegenerative diseases. The classic drug targets are usually enzymes, ion channels, or receptors, the PPI indicate new potential therapeutic targets. Therefore, targeting PPI is a new direction in treating diseases and an essential strategy for the development of new drugs.
However, the design of modulators targeting PPI still faces tremendous challenges, such the difficult PPI interfaces for the drug design, lack of ligands reference, lack of guidance rules for the PPI modulators development and high-resolution PPI proteins structures.
With the development of high-throughput technology, high-throughput screening is also gradually used for the identification of PPI inhibitors, but the compound library used for conventional target screening is not very effective in screening PPI inhibitors. To improve screening efficiency, MCE carefully selected 826 PPI inhibitors and mainly targeting MDM2-p53, Keap1-Nrf2, PD-1/PD-L1, Myc-Max, etc. MCE Protein-protein Interaction Inhibitor Library is a useful tool for PPI drug discovery and related research.

The transforming growth factor beta (TGF-β) signaling pathway is involved in many cellular processes in both the adult organism and the developing embryo including cell growth, cell differentiation, apoptosis, cellular homeostasis and other cellular functions. The TGF-β superfamily comprises TGF-βs, bone morphogenetic proteins (BMPs), activins and related proteins. Signaling begins with the binding of a TGF beta superfamily ligand to a TGF beta type II receptor. The type II receptor is a serine/threonine receptor kinase, which catalyzes the phosphorylation of the Type I receptor. The type I receptor then phosphorylates receptor-regulated SMADs (R-SMADs) which can now bind the coSMAD (e.g. SMAD4). R-SMAD/coSMAD complexes accumulate in the nucleus where they act as transcription factors and participate in the regulation of target gene expression. Deregulation of TGF-β signaling contributes to developmental defects and human diseases, including cancers, some bone diseases, chronic kidney disease, etc.
MCE designs a unique collection of 458 TGF-beta/Smad signaling pathway compounds. TGF-beta/Smad Compound Library acts as a useful tool for TGF-beta/Smad-related drug screening and disease research.

DCA is a Fluorescent probe for visualization of phase behavior in ER membranes. DCA is an ER-targeting, polarity-responsive NIR ratiometric probe, with its p-toluenesulfonamide group responsible for ER localization; its sensitivity to polarity relies on its donor-π-acceptor (D-π-A) structure, where aniline acts as the donor and dicyanomethylene acts as the acceptor, driving an intramolecular charge transfer (ICT) process upon excitation. In environments with low polarity, such as the closely packed, low water content ERₒ phase of ER membranes, DCA emits at a shorter wavelength, while in high polarity environments like the loosely packed, higher water content ERd phase, ICT leads to a red-shifted emission, allowing discrimination of the two phases via dual NIR emission colors and ratiometric imaging. Ex/Em = 488/570–620 nm and 488/665–735 nm; additional excitation/emission pairs include Ex/Em = 488/631 nm in low polarity 1,4-dioxane and Ex/Em = 488/677 nm in 1,4-dioxane with 30% water, the higher polarity condition. It shows a large Stokes shift of ~170 nm, and pH, viscosity, and biologically relevant species including Cys, GSH, H₂O₂, and metal ions do not exert marked interference on its fluorescence spectra[1].
