Cat. No.: HY-W051199
CAS No.: 4210-66-6
Synonyms: o-Phosphohomoserine
O-Phosphono-L-homoserine (o-Phosphohomoserine) is an intermediate in threonine synthesis in bacteria and plants, and can also be hijacked by MetM in some Streptomyces species to enter a novel methionine synthesis pathway. O-Phosphono-L-homoserine acts as a weak antagonist of the NMDA receptor. O-Phosphono-L-homoserine can be used as a substrate for studies on amino acid metabolism of the aspartate family, a control for mechanism studies of PLP enzymes, and a reference for structure-activity relationship studies of NMDA receptor ligands .

(2-Sulfanylethyl)phosphonic acid (compound 2) is a thiol-containing alkylphosphonic acid inhibitor of purple acid phosphatase (PAP), which inhibits PAP derived from red kidney beans with an IC50 of 3000 μM. The phosphonic acid group of (2-Sulfanylethyl)phosphonic acid acts as a non-hydrolyzable phosphate substrate mimic, and the terminal thiol is designed to enhance interactions with the dinuclear metal active center of PAP. (2-Sulfanylethyl)phosphonic acid can be used in studies related to PAP inhibitors and the structure-activity relationships of dinuclear metal phosphatase inhibition .

Endocrinology

Tyr-Ala-N-(1,3-dimethylbutyl)glycinamide is a μ/δ opioid receptor ligand with high μ opioid receptor selectivity and agonist activity. Tyr-Ala-N-(1,3-dimethylbutyl)glycinamide has an IC50 of 237 nM for μ receptors and 1050 nM for δ receptors. Tyr-Ala-N-(1,3-dimethylbutyl)glycinamide shows Ki values of 17 nM for μ receptors and 480 nM for δ receptors. Tyr-Ala-N-(1,3-dimethylbutyl)glycinamide inhibits electrically evoked contractions of guinea pig ileum and mouse vas deferens. Tyr-Ala-N-(1,3-dimethylbutyl)glycinamide serves as a starting compound for structure-activity relationship investigations of μ receptor recognition .

370 compounds

Peptidomimetics are compounds whose essential elements (pharmacophore) mimic a natural peptide or protein in 3D space and which retain the ability to interact with the biological target and produce the same biological effect. Peptidomimetics are designed to circumvent some of the problems associated with a natural peptide: e.g. stability against proteolysis (duration of activity) and poor bioavailability. Certain other properties, such as receptor selectivity or potency, often can be substantially improved. The design and synthesis of peptidomimetics are most important because of the dominant position peptide and protein-protein interactions play in molecular recognition and signaling, especially in living systems. Hence mimics have great potential in drug discovery.

MCE Peptidomimetic Library contains 370 compounds including peptoid, α-helix mimetics, β-turn/sheets mimetics, etc. This library is an indispensable tool of structure-activity relationships in drug discovery.

2,256 compounds

At the forefront of innovative drug discovery, every medicinal chemist faces the challenge of rapidly identifying high-quality hit compounds from vast repositories of chemical resources.

The MCE Natural Product Diversity Scaffold Library is the result of a streamlined optimization process built upon our existing natural product collection. Adhering to the rigorous selection principle of "retaining only one representative compound per BMS scaffold", we have concentrated the diversity of thousands of compounds into a high-value, low-redundancy core set containing 2,256 compounds. All compounds are derived from natural sources, inheriting their inherent advantages of structural complexity and drug-likeness. By eliminating redundancy, the library size is significantly reduced without any compromise to chemical diversity. This approach effectively lowers the cost and time required for primary screening while simplifying downstream data analysis and structure-activity relationship (SAR) studies.

Synonyms: 4-Hydroxy-N-methyltryptamine; 4-HO-NMT
Norpsilocin (4-hydroxy-N-methyltrypt amine; 4-HO-NMT) is a natural tryptamine alkaloid isolated from the hallucinogenic mushroom Psilocybe cubensis. Norpsilocin activates human 5-HT2 receptors (5-HT2A: EC50 = 8.4 nM; 5-HT2B = 12.8 nM; 5-HT2C = 39.6 nM) and displays binding affinity toward 5-HT1 receptors (5-HT1B: Ki = 212 nM; 5-HT1D = 48.9 nM; 5-HT1E = 81.7 nM). Norpsilocin induces β-arrestin recruitment at the 5-HT1B receptor. Norpsilocin fails to produce psychedelic-like effects in mice, whereas high doses can induce hypothermia in vivo. Norpsilocin acts as an important research tool for exploring the structure–activity relationship of tryptamine hallucinogens and the pharmacology of serotonin receptors .

10855 compounds

The rising prevalence of multidrug-resistant and extensively drug-resistant bacteria, combined with emerging resistance mechanisms and the limitations of existing antibacterial drugs, creates an urgent need for novel antibacterial agents. Antibacterial compound libraries serve as key tools to support antibacterial drug screening and development.

This library features structurally diverse compounds, including small-molecule scaffolds and natural product derivatives, and exhibits diverse antibacterial mechanisms of action. For example, these compounds exert antibacterial effects by disrupting bacterial cell structures, interfering with bacterial metabolic processes, and inhibiting nucleic acid synthesis. The derivation of scaffold structures enhances their activity against drug-resistant bacteria and their selectivity against different types of bacteria. This library can be used for the high-throughput screening of novel antibacterial drug candidates and the identification of potent compounds against drug-resistant and multidrug-resistant bacteria. Additionally, it provides a reference for compound structural modification, enabling further in-depth research on the structure-activity relationships(SARs) of antibacterial drugs. It can also be applied to the exploration of bacterial resistance mechanisms and reversal strategies, as well as the discovery of antibacterial molecules that inhibit efflux pumps and restore drug susceptibility.

The library contains 10855 structurally diverse drug-like compounds. Its core compound sources include analogs of known antifungal active moleculeswith a similarity score of ≥ 0.6. MCE has collected more than 1900 antibacterial molecules. All screened compounds conform to lead-like physicochemical properties, providing valuable support for the research and development of novel antibacterial drugs.
