Imipenem (hydrate) Artikelnummer: Cay16039-100
Imipenem is an intravenous beta-lactam antibiotic effective against a wide range of Gram-positive and Gram-negative bacteria (MICs range from 0.5-2 µg/ml for E. cloacae and P. aeruginosa), including several multi-drug resistant bacterial species. Imipenem acts by interfering with bacterial cell wall synthesis.

NADPH, tetrasodium salt Artikelnummer: 16156.1
Nicotinamide adenine dinucleotide phosphate, abbreviated NADP+ or, in older notation, TPN (triphosphopyridine nucleotide), is a coenzyme used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent. NADPH is the reduced form of NADP+. NADP+ differs from NAD+ in the...

Tamoxifen Artikelnummer: Cay13258-1
There are two homologous nuclear receptors for the hormone 17beta-estradiol (estrogen), commonly called ERalpha and ERbeta. Receptor activation leads to the formation of homo- and hetero-dimers, which in turn interact with accessory proteins to regulate gene transcription. Tamoxifen is a selective estrogen receptor...
