N-Nonanoyl-L-homoserine lactone

Biochemical Assay Reagents

Quorum sensing is a regulatory system used by bacteria to control gene expression in response to increased cell density. This regulatory process manifests itself in a variety of phenotypes, including biofilm formation and virulence factor production. Coordinated gene expression is achieved through the production, release and detection of small diffusible signaling molecules called autoinducers. N-acylated homoserine lactones (AHLs) comprise a class of such autoinducers, each of which generally consists of a fatty acid coupled to a homoserine lactone (HSL). Modulation of bacterial quorum-sensing signaling systems to suppress pathogenesis represents a new approach to antimicrobial research for infectious diseases. AHLs differ in acyl length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signaling specificity through the affinity of the LuxR family of transcriptional regulators. C9-HSL is a rare odd-numbered acyl carbon chain produced by wild-type Erwinia carotovora strain SCC 3193 grown in nutrient-rich Luria-Bertani broth (LB) medium.

These differences confer signaling specificity through the affinity of the LuxR family of transcriptional regulators. C18-HSL, one of four lipophilic long acyl side chain AHLs produced by the LuxI AHL synthase homolog SinI, is involved in quorum-sensing signaling in strains of Rhizobium meliloti (a nitrogen-fixing bacterial symbiont of the legume M. sativa) . C18-HSL and other hydrophobic AHLs tend to localize in the relatively lipophilic environment of bacterial cells and cannot diffuse freely across the cell membrane. Long-chain N-acyl homoserine lactones can be exported from cells by efflux pumps, or can be transported between communicating cells by extracellular outer membrane vesicles.

Parthenin acts as an antifeedant against the 6th instar larvae of the tobacco cutworm (Spodoptera litura). Parthenin shows insecticidal activity against adult cowpea weevils (Callosobruchus maculatus). Parthenin inhibits seed germination and seedling growth of sicklepod (Cassia tora). Parthenin possesses nematicidal activity against the 2nd instar larvae of the southern root-knot nematode (Meloidogyne incognita). Parthenin serves as a research agent for studies related to cancer, malaria, amoebiasis, inflammatory diseases, and bacterial infections .

Spermine-d8 tetrahydrochloride

Spermine-d₈ (tetrahydrochloride) is the deuterium labeled Spermine tetrahydrochloride. Spermine tetrahydrochloride is a polyamine nitric oxide donor that can provide nitric oxide to platelets and inhibit platelet activation to a certain extent concentration-dependently. Spermine tetrahydrochloride occurs in mammalian tissues, plants, bacteria, ribosomes and bacteriophage. Spermine tetrahydrochloride inhibits primary human embryo lung fibroblasts in vitro. Spermine is a natural antioxidant and anti-inflammatory agent. Spermine is known to inhibit some bacterial cultures, especially strains of Staphylococcus aureus. Spermine induces neurotoxicity in the striarum dose-dependently. Spermine can reversibly inhibits DNA synthetic response, mixed lymphocyte response and the induction of cytolytic lymphocyte response in primary cultures of murine spleen cells .

HY-B0960S

Sulfabenzamide-d4

Sulfabenzamide (N-Sulfanilylbenzamide)-d₄ is the deuterium labeled Sulfabenzamide (HY-B0960). Sulfabenzamide is a sulfonamide antibacterial agent. Sulfabenzamide exhibit antibacterial activity against Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 8739). Sulfabenzamide can promote autophagic cell autophagy in breast cancer cells through p53/ DRAM pathway. Sulfabenzamide increases caspase-3 activity, deactivates PARP1 and DNA-PK, downregulates AKT1 and AKT2. Sulfabenzamide can be used for the researches of breast cancer and bacterial infections .

HY-Y1010S

Oxiran-2-ylmethanol-d5

Oxiran-2-ylmethanol-d₅ is the deuterium labeled Oxiran-2-ylmethanol (Glycidol) (HY-Y1010). Oxiran-2-ylmethanol is an ester product. Oxiran-2-ylmethanol induces base pair point mutations in bacterial strains and structural chromosome aberrations in cultured cells. Oxiran-2-ylmethanol forms N-(2,3-dihydroxypropyl)valine hemoglobin adducts. Oxiran-2-ylmethanol acts as an animal carcinogen but does not significantly induce micronucleated immature erythrocytes in animal bone marrow. Oxiran-2-ylmethanol enables anionic polymerization to produce linear poly(glycidol). Oxiran-2-ylmethanol can be used for cancer-related research .

HY-D0024S1

Azidocillin		Azide
Azidocillin, a semi-synthetic Penicillin, is an orally active β-lactam antibiotic. Azidocillin bears an azide functionality and retains on-target activity within bacteria. Azidocillin can be used to research osteitis caused by dental surgery, otitis media, enterococcal septicemia and other bacterial infectious diseases . Azidocillin is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

HY-151738

Fmoc-Aeg(N3)-OH		Azide
Fmoc-Aeg(N3)-OH is a click chemistry reagent containing an Azide. Alkylating the Nitrogen of an amide bond results in peptoid structures, which leads to conformational restrains, like N-methylation and allows backbone derivatisation. Altering cytotoxicity, bacterial cell selectivity and receptor pharmacology through formation of peptoid derivatives have been published for Cilengitide, Piscidin 1, and MC3, MC4 and MC5 receptor agonist. This building block enables design of macrocycles through intermolecular crosslinking or backbone stabilization through intermolecular ring-closure. This compound is a potential building block for the construction of (customized) peptide nucleic acids (PNAs) and for peptoid synthesis . Fmoc-Aeg(N3)-OH is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
