Covalent Fragment Library

8,567 compounds

Covalent inhibitors are small molecules that can bind specifically to target proteins through covalent bonds and inhibit their biological functions. Although for a long time, covalent targeting has been playing a subordinate role in drug discovery, with an increasing number of reports on successful clinical applications of such drugs, the potential of these agents is now being acknowledged.

Covalent ligands rely on reactive groups (“warheads”), and new warheads are key to expanding the scope of covalent modalities. 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 8,900 fragment molecules with covalent modification potential, which can target various reactive amino acid residues and can be used for fragment-based covalent drug discovery.

HY-L024

Histone Modification Research Compound Library

904 compounds

A histone modification, a covalent post-translational modification (PTM) to histone proteins, includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation, etc. In general, histone modifications are catalyzed by specific enzymes that act predominantly at the histone N-terminal tails involving amino acids such as lysine or arginine, as well as serine, threonine, tyrosine, etc. The PTMs made to histones can impact gene expression by altering chromatin structure or recruiting histone modifiers. Histone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair. Deregulation of histone modification contributes to many diseases, including cancer and autoimmune diseases.

MCE owns a unique collection of 904 bioactive compounds targeting Epigenetic Reader Domain, HDAC, Histone Acetyltransferase, Histone Demethylase, Histone Methyltransferase, Sirtuin, etc. Histone Modification Research Compound Library is a useful tool for histone modification research and drug screening.

HY-L915

Lysine Focused Covalent Fragment Library

421 compounds

Lysine is the second most common target residue used in the design of TCIs and related covalent ligands. Its appeal lies in its abundance in human proteins, which is approximately three times higher than that of cysteine (5.8% vs. 1.9%). This significantly increases the number of proteins suitable for covalent targeting, especially given that many human proteins lack ligandable cysteine residues. Moreover, it has been suggested that functional lysines have a lower probability of being replaced by mutation, as they often play a crucial role in catalysis by acting as bases or nucleophiles. Additionally, lysines are essential for maintaining the structural integrity of proteins and for regulating post-translational modifications (PTMs). Consequently, targeting lysine has garnered significant interest in recent years.

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 445 fragment molecules which can target lysine residue and can be used for fragment-based covalent drug discovery.

HY-L945

Sulfonyl Fluoride Fragment Library

1162 compounds

Sulfonyl fluoride (-SO₂F) overcomes the bottleneck of target selectivity in traditional covalent warheads through its unique chemical and biological properties, which rely heavily on cysteine (Cys) residues. Featuring high stability and tunable electrophilicity under physiological conditions, it can target a wide range of nucleophilic residues including lysine (Lys), tyrosine (Tyr), serine (Ser), and histidine (His). It offers the advantages of a broader druggable space, lower off-target risks, and long-lasting efficacy, with numerous reported cases in the research of covalent inhibitors, Molecular glue, PROTACs, and chemical biology probe development.

MCE constructs a highly diverse sulfonyl fluoride fragment library based on the reactivity, stability and physiological compatibility of sulfonyl fluoride. The library contains 1000 efficiently synthesized and stable sulfonyl fluoride fragments, which ensure precise reactivity of the warhead and retain sufficient derivatization space for subsequent optimization. Combined with the modular strategy of SuFEx click chemistry, it enables versatile modification of compounds and functionalization of complex molecules, improves the efficiency of structural optimization and rapidly expands druggability, making it suitable for high-throughput probe and custom covalent library construction. It provides an efficient research tool for the development of broad-spectrum covalent inhibitors targeting Lys/Tyr/Ser/His, covalent PROTACs for E3 ligases and chemical biology probe development, meeting the requirements of modern drug research for high throughput, high success rate and high derivatization potential.

BC-GLA-NHS

CLIP-GLA-NHS

Fluorescent Dyes

BC-GLA-NHS (CLIP-GLA-NHS) is a NHS-labeled CLIP tag, which is an amine-reactive crosslinker and can achieve site-specific protein labeling. The NHS ester of BC-GLA-NHS reacts with the primary amine of the target molecule (such as antibodies, quantum dots) in a pH 7.5-8.5 buffer solution to form a stable amide bond. After coupling, the BC molecule undergoes a nucleophilic substitution reaction with the active site (Cys) of the CLIP-tagged fusion protein, releasing benzylcytosine and forming an irreversible thioether bond, achieving covalent labeling. BC-GLA-NHS can be used for click chemistry labeling .

mPEG750-amine

mPEG750-NH2

Biochemical Assay Reagents

mPEG750-amine (mPEG750-NH2) is a chemical modification reagent for nanoparticles, capable of covalently binding to Ad-PVA to form Ad-PVA-PEG polymers. mPEG750-amine stabilizes gene delivery complexes by providing steric hindrance, reducing particle aggregation, while enhancing the water solubility and serum stability of the complex, reducing carrier cytotoxicity, and assisting in the efficient condensation of pDNA by cationic components to form nanoparticles that can be endocytosed by cells. mPEG750-amine can also be used to synthesize folate-conjugated polymer micelles for encapsulating the anticancer agent Camptothecin (HY-16560). Folate-conjugated polymer micelles are effective carriers for poorly soluble anticancer drugs, capable of avoiding macrophages and acting through folate receptor (FR)-mediated endocytosis to target tumor cells. mPEG750-amine can be applied to research in the field of non-viral gene delivery, as a component of gene delivery vectors, facilitating the safe and efficient delivery of nucleic acid drugs to target cells .

N-Acetylserine (N-Acetyl-L-serine) is a complement pathway modulator targeting activated third complement protein (C3b) and an amino-terminal residue (an *N-terminal acetylation modification* group). N-Acetylserine reacts with the exposed thioester group of C3b** via its hydroxyl group, thereby blocking the covalent binding of glycerol to this thioester group. N-Acetylserine widely exists in soluble proteins of mammalian cells (accounting for approximately 80% of such proteins). N-Acetylserine has a blocking property that prevents direct Edman sequencing of proteins; deblocking is achievable through trifluoroacetic acid-catalyzed N→O acetyl migration followed by β-elimination. N-Acetylserine is suitable for sequencing of proteins with N-terminal acetylserine modification .
