Antibiotics Library

752 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 752 antibiotics, including penicillins, cephalosporins, tetracyclines, macrolides, etc. MCE Antibiotics Library is a useful tool for anti-bacterial or anti-cancer drugs discovery.

Antibacterial Compound Library

1,904 compounds

Antibacterial agents are a group of materials that fight against pathogenic bacteria. Thus, by killing or reducing the metabolic activity of bacteria, their pathogenic effect in the biological environments will be minimized. The most widely used antibacterial agents exert their effects on bacterial cell wall synthesis, protein synthesis, DNA replication and metabolic pathways. However, resistance to antimicrobial agents has become a major source of morbidity and mortality worldwide. The main mechanisms of resistance are limiting uptake of a drug, modification of a drug target, inactivation of a drug, and active efflux of a drug. Therefore, it is an urgent need to develop new drugs targeted at resistant organisms.

MCE offers a unique collection of 1,904 compounds with validated antibacterial activities. MCE antibacterial compound library is an effective tool for drug repurposing screening, combination screening and biological investigation.

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.

Cefpodoxime Proxetil-d6

Cefpodoxime Proxetil-d₆ (U-76,252-d₆) is deuterium labeled Cefpodoxime Proxetil. Cefpodoxime proxetil is an orally administered broad spectrum third-generation cephalosporin. Cefpodoxime proxetil has anti-bacterial activity. Cefpodoxime proxetil binds to penicillin binding proteins (PBPs) which inhibits peptidoglycan synthesis, finally results in interfering bacterial cell wall biosynthesis .

HY-B1190S2

Cefadroxil-13C6

Cefadroxil- ¹³C₆ (BL-S 578- ¹³C₆) is ¹³C labeled Cefadroxil (HY-B1190). Cefadroxil is an orally active broad-spectrum cephalosporin antibiotic. Cefadroxil inhibits bacterial cell wall synthesis and enhances the expression of glutamate transporter-1. Cefadroxil is dependent on the intestinal peptide transporter PepT1 for small intestinal absorption. Cefadroxil has inhibitory and bactericidal activity against a variety of Gram-positive and Gram-negative bacteria and has analgesic effects on neuropathic pain .

HY-N7101S

Cefpodoxime proxetil-d7

Cefpodoxime proxetil-d7 (U-76-d7,252-d7; CS-807-d7) is the deuterium labeled Cefpodoxime Proxetil (HY-N7101). Cefpodoxime Proxetil is an orally active broad spectrum third-generation cephalosporin with potent antibacterial activity against both Gram-positive and Gram-negative bacteria including staphylococci, streptococci, Haemophilus influenzae, Neisseria gonorrhoeae, Escherichia coli, Klebsiella pnuemoniae, Citrobacter spp, and Proteus spp. Cefpodoxime Proxetil binds to penicillin binding proteins (PBPs), which inhibits peptidoglycan synthesis, finally results in interfering bacterial cell wall biosynthesis. Cefpodoxime Proxetil can be used against skin structure infections, acute otitis media, pharyngitis, tonsillitis, upper respiratory tract infection, urinary tract infections and sexually transmitted diseases .

HY-W015551S

trans-2-Decenal-d2

trans-2-Decenal-d₂ ((E)-Dec-2-enal-d₂) is deuterated labeled trans-2-Decenal (HY-W015551). trans-2-Decenal ((E)-Dec-2-enal) acts as a urease inhibitor and antibacterial agent against Helicobacter pylori, with an IC₅₀ of 9.484 μg/mL against Helicobacter pylori urease. trans-2-Decenal reduces the urease activity of Helicobacter pylori, and possesses antibacterial, bactericidal, anti-biofilm and anti-migratory activities. It alters the morphology of Helicobacter pylori, induces bacterial rupture, inhibits biofilm formation, reduces the number of mature biofilms and impairs the migratory capacity of Helicobacter pylori. trans-2-Decenal disrupts the cell wall integrity of Phytophthora capsici, damages membrane integrity and permeability, triggers intracellular reactive oxygen species (ROS) accumulation, decreases glutathione levels and disrupts the mitochondrial membrane potential of Phytophthora capsici. trans-2-Decenal is applicable to studies related to Helicobacter pylori and plant diseases induced by and Phytophthora capsici .

HY-W012669S

Phthalaldehyde-d4

Phthalaldehyde-d₄ (Phthaldialdehyde-d₄) is the deuterium labeled Phthalaldehyde (HY-W012669). Phthalaldehyde reacts with proteins containing primary amines and blocked amino-terminal peptides of amino acids. Phthalaldehyde stabilizes bacterial outer membranes and cell walls, increases the optical density of bacterial cell suspensions, and inhibits bacterial lysis induced by ethylenediaminetetraacetic acid and sodium dodecyl sulfate. Phthalaldehyde exhibits bactericidal activity against Gram-negative vegetative bacteria.
