Synonyms: 6-tert-Butyl-2,4-xylenol
Research Areas:
2-(tert-Butyl)-4,6-dimethylphenol (6-tert-Butyl-2,4-xylenol) is an electrophilic alkylating agent, gasoline antioxidant and hydration substrate. 2-(tert-Butyl)-4,6-dimethylphenol inhibits SERCA activity in rabbit hindleg microsomes with an IC50 of 53 μM. Oxidation of 2-(tert-Butyl)-4,6-dimethylphenol generates the intermediate BDMP-QM, which covalently modifies nitrogen sites of proteins, polypeptides and free amino acids via Michael addition, triggering covalent modification of macromolecules and mediating cytotoxicity. 2-(tert-Butyl)-4,6-dimethylphenol is widely used in toxicological and biochemical studies of alkylphenols .

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.

CAS No.: 402491-79-6
Synonyms: L-4-Aminoarabinose-BP
Target:
Research Areas:
L-4-Aminoarabinose-bactoprenyl phosphate (L-4-Aminoarabinose-BP) is a substrate of the ArnT enzyme and participates in lipid A modification through covalent bonding. L-4-Aminoarabinose-bactoprenyl phosphate transfers L-4-aminoarabinose (Ara4N) to the lipid A portion of lipopolysaccharide (LPS), mediating cationic modification of lipid A, thereby conferring resistance to cationic antimicrobial peptides (CAMPs) in Gram-negative bacteria. L-4-Aminoarabinose-bactoprenyl phosphate is an endogenous intermediate synthesized in vivo by a series of enzymes such as ArnC and ArnD encoded by the arn operon in Gram-negative bacteria such as Escherichia coli .

Carboxylated magnetic microspheres (low nonspecificity) are functionalized nano- or micron-sized magnetic particles with abundant carboxyl functional groups on their surface. Special chemical treatments reduce the likelihood of nonspecific adsorption. This 1μm carboxylated magnetic microsphere features a core-shell structure: a PS core, an outer layer of iron oxide (Fe3O4), and an outermost encapsulation layer. The carboxyl groups are obtained through polymer modification. Exhibiting low nonspecific adsorption, these microspheres can covalently couple with bioligands such as peptides, proteins, antibodies, and oligonucleotides using specific chemical reagents (e.g., EDC), making them particularly suitable for cell sorting, affinity chromatography, and immunoassay.
Cat. No.: HY-184641
Aminated magnetic microspheres are superparamagnetic magnetic particles with amino functional groups modified on their surface, widely used in biomedical and molecular biology research. This 1μm aminated magnetic microsphere is composed of polystyrene and nano-iron oxide, exhibiting hydrophilicity and good biocompatibility. The aminated magnetic microspheres possess superparamagnetism, fast magnetic response, good monodispersity, ensuring reaction uniformity and detection consistency. The unique rough surface structure and polymer modification give the aminated magnetic microspheres a high amino density, allowing them to covalently couple with bioligands such as peptides, proteins, oligonucleotides, drug molecules, and glycoproteins through the action of special chemical reagents (such as glutaraldehyde). They serve as excellent coating materials and are important carrier tools in medical and biomolecular research.
