Apexbio Technology LLC Linezolid(Synonyms: Zyvox, Zyvoxid, U-100766, PNU-100766, U-100766E, PNU100766, Linezolide), 10mM (in 1mL DMSO), CAS: 165800-03-3.
Linezolid (CAS 165800-03-3) is a synthetic oxazolidinone antimicrobial compound with broad-spectrum activity primarily against Gram-positive bacteria including multi-drug resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) vancomycin-resistant Enterococcus (VRE) and penicillin-resistant Streptococcus pneumoniae Linezolid inhibits bacterial protein synthesis by binding to the 23S ribosomal RNA of the 50S subunit thereby preventing formation of the functional 70S initiation complex In cell-free transcription-translation assays using E coli linezolid demonstrates an IC50 of approximately 1 8 mM Due to its pharmacokinetics and high oral bioavailability linezolid is widely utilized in clinical research related to complicated skin infections and bacterial pneumonia
Apexbio Technology LLC SB 203580 hydrochloride 869185-85-3 10mM (in 1mL DMSO)
SB 203580 hydrochloride (CAS 869185-85-3) is a selective inhibitor targeting the p38 mitogen-activated protein kinases (MAPKs) specifically isoforms p38-MAPK and p38-MAPK It prevents the downstream phosphorylation and activation of MAP kinase-activated protein kinase 2 (MAPKAPK2) exhibiting an IC50 around 70 nM in neonatal myocytes Additionally SB 203580 hydrochloride inhibits MAPKAPK2 activation and heat shock protein 27 (HSP27) phosphorylation induced by IL-1 osmotic stress or arsenite in KB cells with IC50 values below 1 M It also reduces JNK-mediated activation of c-Jun in neonatal rat cardiac myocytes This compound is widely utilized in research into cellular stress responses inflammation pathways and cardiac signal transduction
