BMS-135-L-Lys TFA is a dual-cation prodrug derived from CK2 inhibitor BMS-135 (HY-181022) through esterification with L-lysine using a secondary alcohol. BMS-135-L-Lys TFA achieves enhanced solubility by maintaining protonation of the ε-amino group of the Lys side chain at intestinal pH. BMS-135-L-Lys TFA is released in situ by intestinal wall esterase from the parent drug, significantly increasing the oral bioavailability of the parent drug and overcoming the non-linear pharmacokinetic problem when the dose of the parent drug is increased. BMS-135-L-Lys TFA can be used in related research on colon cancer and lung cancer .

Infection

Cefamandole (sodium) (Standard) is the analytical standard of Cefamandole (sodium). This product is intended for research and analytical applications. Cefamandole (Cephamandole) sodium is a semi-synthetic second-generation cephalosporin antibiotic with broad-spectrum antimicrobial activity. Cefamandole sodium is resistant to hydrolysis by β-lactamases produced by some Gram-negative bacteria. Cefamandole sodium kills Gram-positive cocci and various Gram-negative bacilli mainly by inhibiting cell wall synthesis, but it is inactive against Pseudomonas, Proteus vulgaris and Providencia stuartii, and its efficacy is affected by inoculum size. The plasma elimination half-life of Cefamandole sodium in rats is only 0.4 h, it is mainly excreted in urine in biologically active form, and it hardly penetrates the non-inflamed blood-brain barrier. Cefamandole sodium is widely used in studies related to bacterial infections .

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 1,994 compounds with validated antibacterial activities. MCE antibacterial compound library is an effective tool for drug repurposing screening, combination screening and biological investigation.

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

Cefuroxime axetil is an orally effective broad-spectrum β-lactam antibiotic that targets bacterial penicillin-binding proteins (PBPs, such as PBP3 and PBP1). Cefuroxime axetil inhibits cell wall synthesis, leading to bacterial lysis and death, with a minimum inhibitory concentration (MIC) of 0.12-4 mg/L for non-typeable Haemophilus influenzae (NTHi). Cefuroxime axetil is hydrolyzed by esterase to the active ingredient Cefuroxime (HY-B1256A) after oral absorption. Topical administration of Cefuroxime via bioadhesive nanoparticles (BNPs) can prolong the drug's retention time in the middle ear (≥7 days). Cefuroxime axetil can be used in the study of otitis media (especially NTHi infection). Cefuroxime axetil can achieve precise antibacterial effects through oral or topical nano-delivery systems, reducing systemic exposure and the risk of antibiotic resistance .
