IP6C is a specific inhibitor and phage sensitizer targeting type II Thoeris systems. IP6C competitively binds to histidine in the catalytic pocket of ThsB, blocks the production of the His-ADPR alarm signal and inhibits ThsA activation, thereby relieving bacterial stasis of phage replication. IP6C selectively resensitizes drug-resistant bacteria carrying type II Thoeris systems (such as Pseudomonas aeruginosa) to phage lysis, without affecting other bacteria, and shows no toxicity to mice and human cell lines. IP6C significantly improves the survival rate of infected mice, and can be used to overcome bacterial phage defense mechanisms and study Pseudomonas aeruginosa infections .
Thoeris system: (named after the Egyptian goddess of fertility and protection), is a widespread anti-phage immune defense system in bacteria and archaea. Thoeris system belongs to the "Abortion Infection (Abi)" mechanism of bacteria: when an individual bacterium detects phage invasion, it initiates a suicide program and dies, thereby blocking phage replication and spread, and protecting the surrounding bacterial population from infection.

Biotoxins, also referred to as natural toxins, are chemical substances produced by plants, animals, or microorganisms that exert toxic effects on other living organisms. Due to unique biological activities, biotoxins have been widely applied in molecular biology, physiology, pharmacology, and the clinical diagnosis and treatment of various human diseases, becoming an important source of natural drug development. Biotoxins can specifically bind to and interfere with intracellular signaling molecules or receptors, thereby altering cellular signaling processes. Leveraging this characteristic, biotoxins can be used to study the regulatory mechanisms of cellular signaling pathways. For example, neurotoxins such as snake venom peptides can be used to investigate the functional regulation of neurotransmitter receptors and ion channels. Additionally, biotoxins have demonstrated significant potential in drug development across various fields, including neurological diseases, cardiovascular diseases, anticoagulation, and anti-cancer therapies. With advancements in high throughput screening, structural optimization, and antibody-toxin conjugation technologies, numerous biotoxins or their structural analogs have been successfully brought to market, such as Ziconotide, Captopril, Bivalirudin, and Eptifibatide.
MCE offers 91 types of biotoxins, including neurotoxins, cardiotoxins, mycotoxins, and more.

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 covalent inhibitor library contains 1,618 small molecules including identified covalent inhibitors and other bioactive molecules having common covalent reactive groups as warheads, such as acrylamides, activated terminal acetylenes, Sulfonyl fluorides/esters, cloracetamides, alkyl halides, epoxides, aziridines, disulfides, etc.

Liposomes are spherical or multilayered spherical vesicles formed by the self-assembly of diacyl chain phospholipids (lipid bilayers) in aqueous solutions, which can be made from natural or synthetic phospholipids and exhibit good biocompatibility and low toxicity. They can serve as delivery carriers for various bioactive substances (such as drugs, proteins, nucleic acids, etc.) and are widely used in biomedical and chemical research. The main advantages of liposomes include 1) Protective effect: Their bilayer structure can protect encapsulated molecules from enzymatic degradation, oxidation, and other influences, extending stability and activity; 2) Active targeting: Surface modifications enable active targeting, enhancing the concentration of drugs or molecules in specific tissues or cells; 3) Customizability: The composition and structure of liposomes can be adjusted according to needs, such as altering phospholipid types or adding targeting ligands. These properties make liposomes highly valuable in developing novel drug delivery systems, serving as nucleic acid carriers for gene transfection, studying cellular uptake mechanisms and drug release kinetics, as well as developing functional food additives to improve the bioavailability of nutritional components.
MCE contains 227 liposome compounds, which is a good tool for drug delivery-related studies.

Copper is an important co-factor of all biological enzymes, but if the concentration exceeds the threshold of maintaining the homeostasis mechanism, copper will lead to cytotoxicity. This death mechanism has been named "Cuproptosis".
The mechanism of cuproptosis distinct from all other known mechanisms of regulated cell death, including apoptosis, pyroptosis, necroptosis, and ferroptosis.
Copper combine with the lipoylated components of the tricarboxylic acid cycle (TCA), leading to lipoylated protein aggregation and subsequent loss of iron-sulfur cluster proteins, ultimately resulting in protein toxicity stress and cell death. Studies have shown that the necessary factors for cuproptosis include the presence of glutathione, mitochondrial metabolism of galactose and pyruvate, and glutamine metabolism.
Targeted regulation of cuproptosis is a potential choice to treat cancer, rheumatoid arthritis, and other diseases. For example, up-regulation of LIPT1 may inhibit the occurrence and development of tumors by destroying TCA in mitochondria and then inducing cuproptosis.
MCE supplies a unique collection of 446 cuproptosis-related compounds, all of which act on the targets or signaling pathways related to cuproptosis and may have in inhibitory or activated effect on cuproptosis. MCE Cuproptosis Library is a useful tool for drug research related to cancer, rheumatoid arthritis, and other 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.
