Cysteine Protease Focused Covalent Library

2,113 compounds

Pattern Recognition Receptors Library

313 compounds

Pattern Recognition Receptors (PRRs) are a crucial class of protein molecules expressed in cells of the innate immune system. The core function of Pattern Recognition Receptors is to recognize Pathogen-Associated Molecular Patterns (PAMPs) and Damage-Associated Molecular Patterns (DAMPs). Upon recognizing and binding to PAMPs or DAMPs, PRRs rapidly initiate intracellular signaling pathways (such as the NF-κB, IRF, and inflammasome pathways). This triggers the production of inflammatory factors, chemokines, and type I interferons, thereby initiating inflammatory responses to eliminate pathogens or repair damage. PRRs represent the body's first line of defense against infection, and the rapidity and broad specificity of their response are crucial for host survival. However, aberrant activation of PRR signaling is also a cause of many chronic inflammatory diseases, autoimmune disorders, and neurodegenerative diseases. Therefore, precisely regulating PRR activity has become a key therapeutic strategy for these conditions.

MCE has cataloged 313 inhibitors targeting key PRRs, such as NLRs, TLRs, C-type Lectin Receptors (CLRs), and cGAS, to support drug discovery efforts for chronic inflammatory diseases.

HY-L925

Cysteine Protease Focused Library

9,188 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.

Antiviral Lead-like compound library

5,813 compounds

Owing to the widespread transmission and frequent mutation of viral diseases, as well as the continuous emergence of new viruses and drug-resistant strains, antiviral drug development is facing increasingly stringent requirements. Antiviral compound libraries serve as important tools for drug screening, mechanism research and development, enabling the discovery and investigation of various antiviral drugs.

These compounds act through diverse antiviral mechanisms, targeting key steps in viral replication, assembly and invasion. They exert antiviral effects by inhibiting viral nucleic acid synthesis, blocking viral protein processing, and preventing viral binding to host cells. This library covers various types of antiviral compounds, including nucleosides, non-nucleosides, protease inhibitors and integrase inhibitors. It supports research on influenza virus, herpes virus, hepatitis virus, emerging respiratory viruses and other pathogens, and enables high-throughput screening of novel antiviral candidates to rapidly identify potential active compounds against diverse viruses. It also facilitates mechanistic studies to elucidate drug-target interactions and viral resistance mechanisms, and supports the screening of effective compounds against mutant strains for research on viral variation and drug resistance.

This antiviral library consists of 6,804 compounds with lead-like physicochemical properties. The core sources of the compounds include analogs of known antiviral molecues with a similarity score ≥ 0.6. MCE has collected more than 1450 antiviral molecules. As a small-molecule collection with both activity potential and structural modifiability, it provides strong support for antiviral drug research and development.

Cyprodinil (CGA-219417) is a broad-spectrum anilinopyrimidine fungicide and an activator of the aryl hydrocarbon receptor. Cyprodinil also has anti-androgenic and androgenic activities. Cyprodinil can inhibit the biosynthesis of methionine in plant-pathogenic fungi and protect fruits and vegetables from a variety of pathogens .

Nadifloxacin-d5

Nadifloxacin-d₅ (OPC7251-d₅) is deuterium labeled Nadifloxacin (HY-B0506). Nadifloxacin (OPC7251) is a broad-spectrum quinolone antibiotic. Nadifloxacin inhibits bacterial DNA gyrase and topoisomerase IV, interfering with DNA replication. It also suppresses the production of proinflammatory cytokines (such as IL-1α, IL-6, and IL-8). Nadifloxacin exhibits antibacterial activity against various pathogens, including Propionibacterium acnes and Staphylococcus aureus. Nadifloxacin also exhibits anti-inflammatory activity. Nadifloxacin can be used in the research of skin infections such as acne vulgaris, folliculitis, and impetigo .

Temephos-d12

Temephos-d₁₂ is the deuterium labeled Temephos. Temephos (Temefos) is an orally active, blood-brain barrier-permeable organophosphate insecticide and AChE inhibitor. By irreversibly inhibiting AChE to induce cholinergic overactivation, Temephos effectively blocks larval development of Aedes aegypti (yellow fever mosquito) and Aedes albopictus (Asian tiger mosquito), and is commonly used in studies related to Dengue Virus, Zika Virus and other relevant pathogens. Temephos exhibits genotoxicity and neurodevelopmental toxicity, and may also cause liver injury, reproductive system abnormalities and cholinergic poisoning symptoms in mammals. Temephos tends to accumulate in adipose tissues and aquatic organisms, and is excreted via feces after metabolism through oxidation and hydrolysis. Note that CYP-mediated metabolic detoxification may reduce the actual larvicidal efficacy of Temephos against some mosquito species. Temephos can be used in research related to dengue fever, Zika virus disease, chikungunya and dracunculiasis .

HY-W010203S1

2-Decanone-d5-1

2-Decanone-d₅-1 is the deuterium labeled 2-Decanone (HY-W010203). 2-Decanone is an antifungal agent. 2-Decanone inhibits pathogen mycelial growth, spore germination, and appressorium formation. 2-Decanone downregulates spore germination-related genes (MfBmp1) and penetration structure formation genes (MfPls1), inducing reactive oxygen species (ROS) accumulation to trigger mitochondrial damage and subsequent spore apoptosis. 2-Decanone is promising for research of postharvest disease control in fruits and vegetables .

Isopropyl palmitate Propan-2-yl hexadecanoate		Solvents
Isopropyl palmitate is an fatty acid ester. Isopropyl palmitate can be used for design and characterization of bioactive bilayer films. The bilayer membrane not only has the ability to scavenge free radicals and inhibit lipid peroxidation, but also can inhibit the growth of known foodborne pathogens. Isopropyl palmitate can be used as an excipient, such as lubricant, oily carrier, solvent, controlled-release transdermal film. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs .
