18-Crown-6-ether 18C6; 1,4,7,10,13,16-Hexaoxacyclooctadecane	Bacterial	Infection
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 .

Macrocyclic Compound Library	448 compounds
Macrocycles, molecules containing 12-membered or larger rings, are receiving increased attention in small-molecule drug discovery. The reasons are several, including providing access to novel chemical space, challenging new protein targets, showing favorable ADME- and PK-properties. Macrocycles have demonstrated repeated success when addressing targets that have proved to be highly challenging for standard small-molecule drug discovery, especially in modulating macromolecular processes such as protein–protein interactions (PPI). Otherwise, the size and complexity of macrocyclic compounds make possible to ensure numerous and spatially distributed binding interactions, thereby increasing both binding affinity and selectivity. MCE offers a unique collection of 448 macrocyclic compounds which can be used for drug discovery for high throughput screening (HTS) and high content screening (HCS). MCE Macrocyclic Compound Library is a useful tool for discovering new drugs, especially for “undruggable” targets and protein–protein interactions.
