Antibiotics

Calcimycin (Standard) is the analytical standard of Calcimycin. This product is used for research and analytical applications. Calcimycin is an antibiotic and a unique divalent cation ionophore, such as calcium ions and magnesium ions. Calcimycin induces Ca²⁺ -dependent cell death by increasing the intracellular calcium concentration. Calcimycin inhibits the growth of Gram-positive bacteria and some fungi, and also inhibits the activity of ATPase and uncouples the oxidative phosphorylation (OXPHOS) of mammalian cells, inducing apoptosis and autophagy.

Valinomycin (Standard) is the analytical standard of Valinomycin (HY-N6693). This product is intended for research and analytical applications. Valinomycin is a potassium-specific ionophore, the valinomycin-K⁺ complex can be incorporated into biological bilayer membranes with the hydrophobic surface of valinomycin, destroys the normal K⁺ gradient across the membrane, and as a result K_ills the cells, incorporating into liposomes can significantly reduces the cytotoxicity and enhances the targeting effect. Valinomycin exhibits antibiotic, antifungal, antiviral, antitumor and insecticidal efficacy, thus can be used for relevant research.

Filipin III (Standard) is the analytical standard of Filipin III (HY-N6718). This product is intended for research and analytical applications. Filipin III is the major component of Filipin, a 28-membered ring pentaene macrolide antifungal antibiotic produced by S. filipinensis, S. avermitilis and S. miharaensis. Filipin interacts with membrane sterols causing the alteration of membrane structure.

(±)-Nornicotine (Standard) is the analytical standard of (±)-Nornicotine. This product is intended for research and analytical applications. (±)-Nornicotine is the primary metabolite of nicotine that is formed through demethylation of nicotine in the genus Nicotiana tabacum L. (±)-Nornicotine is a precursor of tobacco-specific nitrosamine N-nitrosonornicotine. (±)-Nornicotine has detrimental effects to human health.

Mupirocin (calcium hydrate) (Standard) is the analytical standard of Mupirocin (calcium hydrate). This product is intended for research and analytical applications. Mupirocin (BRL-4910A, Pseudomonic acid) calcium hydrate is an orally active antibiotic isolated from Pseudomonas fluorescens. Mupirocin calcium hydrate apparently exerts its antimicrobial activity by reversibly inhibiting isoleucyl-transfer RNA, thereby inhibiting bacterial protein and RNA synthesis.

Chloramphenicol succinate sodium (Standard) is the analytical standard of Chloramphenicol succinate sodium. This product is intended for research and analytical applications. Chloramphenicol succinate sodium is a prodrug of Chloramphenicol (HY-B0239), acting as a P2Y14R inhibitor with an IC₅₀ of 1.585 nM. Chloramphenicol succinate sodium serves as a competitive substrate and inhibitor of succinate dehydrogenase (SDH), which may account for its toxicity. Chloramphenicol succinate sodium exerts a significant inhibitory effect on colitis. Chloramphenicol succinate sodium can be used in research related to myelosuppression, gray baby syndrome, aplastic anemia, bacterial meningitis and inflammatory bowel disease.

Spiramycin I (Standard) is the analytical standard of Spiramycin I. This product is intended for research and analytical applications. Spiramycin I is a macrolide antibiotic and antiparasitic.
