Antibiotics Library

751 compounds

Antibiotics are types of antimicrobial products used for the treatment and prevention of bacterial infections. Antibiotics can kill or inhibit bacterial growth. Although the target of an antibiotic is bacteria, some antibiotics also attack fungi and protozoans. However, antibiotics rarely have an effect on viruses. The major mechanism underlying antibiotics is the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, protein synthesis, or disruption of membrane structure. Many of these cellular functions targeted by antibiotics are most active in multiplying cells. Since there is often overlap in these functions between prokaryotic bacterial cells and eukaryotic mammalian cells, it is not surprising that some antibiotics have also been found to be useful as anticancer agents.

MCE supplies a unique collection of 751 antibiotics, including penicillins, cephalosporins, tetracyclines, macrolides, etc. MCE Antibiotics Library is a useful tool for anti-bacterial or anti-cancer drugs discovery.

Fungi, due to their unique and diverse secondary metabolic capabilities, have become a valuable resource for natural active molecules. Since the discovery of penicillin, natural products derived from fungi have demonstrated significant application value in areas such as anti-infection, anti-tumor, immune regulation, and metabolic disease research. A large number of clinical drugs, such as antibiotics, immunosuppressants, and lipid-lowering drugs, are derived from fungal metabolites or their structurally optimized derivatives.

MCE fungal-derived compound library contains 90 structurally diverse and bioactive fungal natural products and their derivatives. It can be widely applied in various research fields such as antibacterial, anti-tumor, anti-inflammatory, immune regulation, epigenetics, and cell signaling pathways, providing high-quality tools for natural product drug development and high-throughput screening.

Serine/Threonine Focused Covalent Fragment Library

3,208 compounds

In the research of covalent inhibitors targeting serine and threonine, scientists have found that the nucleophilicity of these hydroxyl groups is significantly enhanced due to the influence of their surrounding environment. This results in higher activity during catalytic reactions. Aspirin, which targets the non-catalytic domain serine (Ser529 in human COX1) of cyclooxygenase, exerts its anti-inflammatory effect through covalent binding. β-lactam antibiotics, which targets the catalytic domain serine of penicillin-binding proteins, interferes with bacterial cell wall synthesis.

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 3,300 fragment molecules which can target serine and threonine residues and can be used for fragment-based covalent drug discovery.

RADA

Fluorescent Dyes

RADA is a fluorescent D-amino acid (FDAA) with high photostability and thermostability, which emits yellow-to-orange fluorescence. RADA shows low outer membrane permeability in wild-type Gram-negative Escherichia coli, but it targets penicillin-binding proteins and L,D-transpeptidases, mimics the interaction between acyl acceptors and enzyme intermediates, and integrates into peptidoglycan during biosynthesis. As a peptidoglycan labeling reagent, RADA metabolically integrates into the nascent peptidoglycan of live bacterial cells, labels the peptidoglycan at the poles and lateral walls of mycobacteria, and enables visualization of peptidoglycan synthesis and remodeling processes. RADA serves as a non-specific stain for fixed cells, is non-toxic to bacterial cells, and its red-shifted excitation/emission spectra reduce phototoxicity. RADA also supports virtual pulse-chase labeling experiments and stochastic optical reconstruction microscopy for sub-diffraction-limited imaging of bacterial cell walls .
