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.

Zinc oxide, <100 nm particle size is a nitrate reductase modulator and growth promoter with plant stress resistance activity and oral toxicity. Zinc oxide, <100 nm particle size acts as a nutrient source for maize plants. By enhancing nitrate reductase activity and reducing free proline levels, it significantly improves plant height, root length and dry matter weight of maize, and its growth-promoting effect is comparable to that of traditional zinc sulfate fertilizer. Zinc oxide, <100 nm particle size induces anemia-related and persistent tissue inflammatory damage, leading to obvious histopathological adverse reactions in the stomach, pancreas, eyes and prostate of rats. Zinc oxide, <100 nm particle size acts as a non-toxic antibacterial agent and selective cytotoxin against multiple bacteria, fungi and spores .

18-Crown-6-ether

18C6; 1,4,7,10,13,16-Hexaoxacyclooctadecane

Biochemical Assay Reagents

18-Crown-6-ether is a type of crown ether compound and a specific structure dissociating agent. 18-Crown-6-ether can compete with K ⁺ for binding to G-quadruplexes, disrupting their stable structure to regulate the functions of related systems. 18-Crown-6-ether combines with K ⁺ and other metal ions to achieve precise ion transmembrane transport. 18-Crown-6-ether can act as an "susceptibility substrate" for the multi-drug efflux pump EmrE (a bacterial multidrug resistance transporter), ultimately inhibiting bacterial growth. 18-Crown-6-ether can be used in microcapsule controlled release and the research on developing antibacterial enhancers .

D-Phenylalanine	Microorganisms Classification of Application Fields Ketones, Aldehydes, Acids Other Diseases Endogenous metabolite Disease Research Fields Source Classification	Endogenous Metabolite
D-Phenylalanine is an atypical D-amino acid and an inhibitor of bacterial biofilm formation. D-Phenylalanine mainly replaces D-alanine (D-Ala) by incorporating into the fourth and fifth positions of bacterial peptidoglycan (PG), changing the cell wall structure, enhancing bacterial acid resistance and affecting biofilm formation. D-Phenylalanine may promote the secretion of peptide tyrosine tyrosine (PYY) in mammals by activating the intestinal GPR109B receptor. D-Phenylalanine can inhibit the maturation of microbial biofilms and promote the release of specific hormones. It can be used for antibacterial preservation, improving the yield of probiotics in the food industry, and studying appetite regulation and blood sugar control in metabolic diseases such as diabetes .
