Amphotericin B Solution, 100X
Amphotericin B is a polyene antifungal agent for yeast, mold and mycoplasma. It was first isolated by Gold, et a., from Streptomyces nodosus in 1955. It is an amphoteric compound composed of a hydrophilic polyhydroxyl chain along one side and a lipophilic polyene hydrocarbon chain on the other. Amphotericin B is poorly soluble in water. Amphotericin B binds to sterols, preferentially to the primary fungal cell membrane sterol, ergosterol. This binding disrupts osmotic integrity of the fungal membrane, resulting in leakage of intracellular potassium, magnesium, sugars, and metabolites and then cellular death.Used in the preparation of baculoviral stocks.Amphotericin B Solution, 100X is composed of USP grade Amphotericin B in a High pH buffer (NaOH/Na+,H2O). The concentration of Amphotericin B in the final product is 0.25 g/L. Group: Biochemicals.

2,3-Oxidosqualene cyclase (OSC) is an important enzyme in the biosynthesis of animal, plant, and fungal sterols. BIBB 515 is a selective and potent inhibitor of 2,3-oxidosqualene cyclase (OSC) with an ED50 value of 0.2-0.5 and 0.36-33.3 mg/kg in rats and mice, respectively. It is concluded that the lipid-lowering effect of BIBB 515 is mainly the result of an inhibition of LDL production rather than due to an increase in LDL catabolism. OSC inhibitors may offer a novel approach for lipid-lowering therapy. Synonyms: BIBB-515; BIBB515. Grades: ≥98%. CAS No. 156635-05-1. Molecular formula: C22H21ClN2O2. Mole weight: 380.9.
