Small molecule covalent inhibitors, or irreversible inhibitors, are a type of inhibitors that exert their biological functions by irreversibly binding to target through covalent bonds. Compared with non-covalent inhibitors, covalent inhibitors have obvious advantages in bioactivity, such that covalent warheads can target rare residues of a particular target protein, thus leading to the development of highly selective inhibitors and achieving a more complete and continued target occupancy in living systems. In recent years, the distinct strengths of covalent inhibitors in overcoming drug resistance had been recognized. However, toxicity can be a real challenge related to this class of therapeutics due to their potential for off-target reactivity and has led to these drugs being disfavored as a drug class. The drug design and optimization of covalent inhibitors has become a hot spot in drug discovery.
MCE Lead-like Covalent Screening Library offers a valuable resource of 1,049 lead-like compounds with commonly used covalent warheads. These warheads, such as acrylamide, activated terminal alkyne, acyloxymethyl ketone, and boronic acid, are capable of reacting with specific amino acid residues, including cysteine, lysine, serine, and histidine. The inclusion of these reactive warheads in the library allows researchers to explore the potential of covalent inhibition, a powerful approach in drug discovery.

Bovine serum albumin-modified gold nanoclusters (BSA-Au NCs) are nanomaterials combining gold nanoclusters and bovine serum albumin (BSA). Composed of several to dozens of gold atoms forming the core of the gold nanoclusters, BSA acts as a protective ligand, coating the surface of the gold nanoclusters. BSA-Au NCs are widely used due to their high luminescence properties and stability over a wide pH range. When Au(III) ions are introduced into a BSA solution, BSA acts as a scaffold protein, isolating and capturing Au ions, similar to the biomineralization behavior of inorganic ions in organisms in nature. The captured Au ions are then reduced in situ by BSA to form Au NCs. The synthesized Au NCs consist of 25-Au atoms and are stable in BSA as BSA-Au NCs, exhibiting strong red fluorescence. BSA-Au NCs possess good biocompatibility and their surface is easily modified or functionalized, making them attractive for many biomedical applications.

Lys-VBOD is a Fluorescent probe for lysosomal viscosity monitoring and live cell imaging. Its detection mechanism depends on viscosity: increased viscosity restricts the twisting of the double bond between the indole and BODIPY fluorophore, as well as the rotation of the single bond between quinoline and BODIPY, which reduces non-radiative decay and leads to enhanced fluorescence intensity in high viscosity environments; it also features a morpholine group that provides lysosome-targeting properties, allowing it to localize to lysosomes for viscosity detection. The probe has excitation/emission wavelengths of Ex/Em = 602/637 nm, and its fluorescence intensity shows a good linear relationship with log-transformed viscosity values. Lys-VBOD is stable across a wide pH range of 5.35 to 10.74, is not affected by macromolecules and proteins like BSA, has a fluorescence lifetime that increases with viscosity, and can visualize real-time lysosomal viscosity changes in live cells under Dexamethasone (HY-14648) stimulation[1].

New drug development is a time-consuming and high-cost process. Drug repurposing (also called drug repositioning, reprofiling or re‑tasking) offers various advantages over developing an entirely new drug for a given indication. First, the risk of failure is lower. Second, the time frame for drug development can be reduced. Third, less investment is needed. Approved drugs have identified bioactivities, good pharmacokinetic characteristics and safety which are suitable for drug repurposing.
MCE owns a unique collection of 3,663 approved compounds which have been completed extensive preclinical and clinical studies and have well-characterized bioactivities, safety and bioavailability properties. MCE FDA-Approved Drug Library Plus, with more powerful screening capability, further complements FDA-Approved Drug Library (HY-L022) by adding some compounds with low solubility or solution stability (Part B) to this library. All those supplementary are supplied in powder form.

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.

Inflammasomes are classic pattern recognition receptors for natural immune responses. Inflammasomes are polymeric protein complexes that regulate inflammatory responses and pyrolytic cell death, thereby exerting the host's defense against microorganisms. Inflammasomes sensors are associated with adapter proteins, activating inflammatory caspase-1, releasing inflammatory cytokines and inducing cell death, endowing the host with defense against pathogens. NLRP1, NLRP3, NLRC4, AIM2, and pyrin are considered typical inflammasomes because they convert cysteine asparaginase-1 into catalytically active capsaicin-1. In addition to infectious diseases, the importance of inflammasomes is also related to various clinical diseases, such as autoimmune diseases, neurodegeneration and metabolic disorders, and the development of cancer. Therefore, it is necessary to strictly regulate the activation and function of inflammasomes to avoid accidental host tissue damage while inducing pathogens to kill the inflammatory response.
MCE designs a unique collection of 178 inflammasomes related compounds. It is a good tool to be used for research on Inflammation, cancer and other diseases.

Resistance refers to the decrease in the effectiveness of drugs in treating diseases or symptoms. Due to the increasing global antibiotic resistance, it may threaten our ability to treat common infectious diseases. Drug resistance is also the main cause of chemotherapy failure in malignant tumors. In approximately 50% of cases, drug resistance exists even before chemotherapy begins. There are many mechanisms of anticancer drug resistance, including increased protein expression that leads to drug removal, mutations in drug binding sites, recovery of tumor protein production, and pre-existing genetic heterogeneity in tumor cell populations. In addition, the issue of drug resistance seems to have affected the development of new anticancer drugs. Drug resistance may be caused by various conditions, such as mutations, epigenetic modifications, and upregulation of drug efflux protein expression. Overcoming multidrug resistance in cancer treatment is becoming increasingly important.

On May 15, 2024, "Dimerization and antidepressant recognition at noradrenaline transporter" was published online by Nature. The research findings were an effort from Shanghai Institute of Materia Medica, Chinese Academy of Sciences. This study unraveled the important neural system target - the noradrenaline transporter (NET), obtaining the binding modes of human NET homodimers with the natural substrate norepinephrine (NE) and six selective antidepressants. It laid an important theoretical foundation for understanding the physiological regulation mechanisms of NET and other monoamine transporters.
The Norepinephrine Transporter (NET) Compound Library is obtained by computer-aided virtual screening based on the HY-L901 compound library . The specific screening process includes molecular docking screening, key pharmacophore screening, and CNS-MPO screening, which can be used for new drug discovery targeting the noradrenaline transporter.
