产品描述
醋酸卡泊芬净(Caspofungin Acetate),CAS NO.179463-17-3,最早分离自G.
lozoyensis的一种棘白菌素类抗真菌剂,是纽莫康定 B0(Pneumocandin
B0,Cat#:MS0112)的衍生物[1]。卡泊芬净有效作用于3959株临床分离的念珠菌(MIC90= 1 µg/ml),包括耐氟康唑或伊曲康唑的分离物;以及38株临床分离的曲霉,包括黄曲霉(A. flavus)、烟曲霉(A.
fumigatus)、黑曲霉(A. niger)和土曲霉(A. Terreus)(MICs
= <0.25-64 µg/ml)[2-3]。卡泊芬净抑制1,3-β-D-葡聚糖合成酶的活性(白色念珠菌膜制备物的IC50=0.6nM)[4]。播散性念珠菌病或曲霉菌病小鼠模型中,卡泊芬净提高存活率[5]。

体外研究(细胞水平):
细胞类型(Cell Type):C. albicans
and C. auris biofilm cells
配制方法(Formulation):Caspofungin dissolved in 5% glucose
water
实验方法(Assay):For antifungal treatment, 100 μL of antifungal solutions
(caspofungin, micafungin, and amphotericin B dissolved in 5% glucose water,
0.9% NaCl, and RPMI-1640, respectively) were added to each well and incubated
at 37 °C for 5 min, 30 min, or 60 min. A maximum concentration was selected
for each drug according to the clinical dose indicated for fungal infections:
500 mg/L for caspofungin (50 mg/body weight diluted with
100 mL or 250 mL solution);

体内研究(动物模型):
动物模型(Animal Model):Juvenile
DBA/2N mice infected with Candida albicans MY1055
配制方法(Formulation):Caspofungin acetate was solubilized and serially diluted in
sterile distilled water.
实验方法(Assay):Antifungal
therapy was initiated at 30 h after infectious challenge andwas given by intraperitoneal (i.p.) injection once
daily for 7 days. Mice were treated with caspofungin at 1, 2, 4, or 8
mg/kg/day, amphotericin B at 1 mg/kg/day, or vehicle control (VC; sterile
distilled water).
