Medchemexpress LLC Natamycin | 7681-93-8 | 99.5% | 5 MG

Natamycin (Pimaricin) is a macrolide antibiotic agent produced by several *Streptomyces* strains. It inhibits fungal growth by preventing amino acid and glucose transport across the plasma membrane. Natamycin is used as a food preservative, an antifungal agent in agriculture, and for fungal keratitis research. It serves as an analytical standard for qualitative, quantitative, and methodological research experiments such as HPLC, GC, and MS.

Enzo Life Sciences Leptomycin B (100µg). CAS: 87081-35-4

A potent and specific nuclear export inhibitor. Leptomycin B alkylates and inhibits CRM1/exportin 1, a protein required for nuclear export of proteins containing a nuclear export sequence (NES). In addition to antifungal and antibacterial activities, blocks the cell cycle and is a potent anti-tumor agent. At low nM concentrations, blocks the nuclear export of many proteins including HIV-1 Rev, MAPK/ERK, and NF-κB/IκB and it stabilizes the expression of p53. Other proteins that are influenced by leptomycin B are actin, c-Abl, cyclin B1, MDM2/p53, Iκb, MPF and PKA. Leptomycin B also inhibits the export and translation of many RNAs, including COX-2 and c-Fos mRNAs, by inhibiting export of ribonucleoproteins. Alternative name: LMB. Formulation: Solution in 100% ethanol. Purity: ≥96% (HPLC). Appearance: Liquid. Solubility: Soluble in methanol or 100% ethanol; insoluble in water. Unstable in DMSO. Long Term Storage: -20°C.
