産品描述

醋酸卡泊芬淨(Caspofungin Acetate),CAS NO.179463-17-3,最早分離自(zì)G. lozoyensis的一(yī)種棘白(bái)菌素類抗真菌劑,是紐莫康定 B0(Pneumocandin B0,Cat#:MS0112)的衍生(shēng)物(wù)[1]。卡泊芬淨有效作用于3959株臨床分離的念珠菌(MIC90= 1 µg/ml),包括耐氟康唑或伊曲康唑的分離物(wù);以及38株臨床分離的曲黴,包括黃曲黴(A. flavus)、煙(yān)曲黴(A. fumigatus)、黑(hēi)曲黴(A. niger)和土(tǔ)曲黴(A. Terreus)(MICs = <0.25-64 µg/ml)[2-3]。卡泊芬淨抑制1,3-β-D-葡聚糖合成酶的活性(白(bái)色念珠菌膜制備物(wù)的IC50=0.6nM)[4]。播散性念珠菌病或曲黴菌病小(xiǎo)鼠模型中,卡泊芬淨提高(gāo)存活率[5]。

體外研究(細胞水(shuǐ)平):

細胞類型(Cell Type):C. albicans and C. auris biofilm cells

配制方法(Formulation):Caspofungin dissolved in 5% glucose water

實驗方法(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);

體内研究(動物(wù)模型):

動物(wù)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.

實驗方法(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).
