Sample solution is provided at 25 µL, 10mM.

Description

Bestatin is known to be an inhibitor of Aminopeptidase N (APN/CD13), which has the IC50 values of 14.9±3.4μM[1]. Bestatin can also inhibits aminopeptidase B and LTA4 hydrolase[2, 3]. Bestatin was shown to enhance antibody-dependent cell mediated cytotoxicity and natural killer cell activity[4].

Bestatin (10μM; 24h) significantly reduced melflufen (125 or 250nM; 24h) induced cytotoxicity in AMOaBTZ cells[5]. Bestatin (0.25mM; 24h) can inhibit the migration and proliferation of breast cancer cells[6].

Bestatin (30mg/kg; i.p. ; 15min) alleviated the acute lung injury in one-lung ventilation model rats[7]. Bestatin (0.1 or 1 or 10mg/kg; i.p. ; 5 or 10 times at 24h intervals) potentiated the humoral response to sheep erythrocytes (SRBC; i.p. ) suspension in mice, resulting in an increased number of plaque-forming cells[8].

Bestatin是氨基肽酶N(APN/CD13)抑制剂,其IC50值为14.9±3.4μM[1]。Bestatin还能抑制氨基肽酶B和LTA4水解酶[2,3]。Bestatin可增强抗体依赖细胞介导的细胞毒性和自然杀伤细胞活性[4]

Bestatin(10μM; 24h)显著削弱了melflufen(125 or 250nM; 24h)诱导的AMOaBTZ细胞毒性[5]。Bestatin(0.25mM; 24h)可抑制乳腺癌细胞的迁移和增殖[6]

使用Bestatin(30mg/kg; i.p. ; 15min)处理单肺通气模型大鼠,Bestatin可减轻大鼠急性肺损伤[7]。使用Bestatin(0.1 or 1 or 10mg/kg; i.p. ; 5 or 10 times at 24h intervals)处理使用SRBC(sheep erythrocytes,绵羊红细胞;i.p.)悬液免疫的小鼠,Bestatin增强了小鼠对SRBC悬液的体液免疫反应,产生更多的空斑形成细胞[8]

实验参考方法

Cell experiment [1]:

Cell lines

Mammary breast cancer cell lines SKRB3

Preparation Method

SKRB3 were cultured in McCoy’s 5A supplemented with 10% fetal bovine serum at 37°C in a humidified 5% CO2 atmosphere. Cells were cultured until they were 70% confluent in 6‑well plate, then a wound was drawn by a sterile 200μl pipette tip. Subsequently, cells were cultured in fresh serum-free medium with/without 0.25mM Bestatin for 24h.

Reaction Conditions

0.25mM; 24h

Applications

Bestatin can inhibit the migration and proliferation of breast cancer cells.
Animal experiment [2]:

Animal models

male and female Balb/c mice

Preparation Method

The mice were immunized intraperitoneally with 0.2ml of 10% SRBC suspension (4×108 cells per mouse). The blood was taken from the jugular vein of cross-bred clinically healthy sheep. The sheep blood was collected in sterile manner into Alsever’s solution containing glucose (2.05%), sodium citrate (0.8%), sodium chloride (0.42%), and citric acid (0.055%) and kept there at 4℃ for at least 3 days. The SRBC suspension was prepared extempore in phosphate-buffered saline (PBS). Bestatin was dissolved in PBS. The agent (doses of 10, 1, and 0.1mg/kg) was injected i.p. to mice, 5 or 10 times at 24h intervals before SRBC immunization. The mice were immunized 24h after the last dose of bestatin.
Anti-SRBC hemagglutinin titre was determined on days 4, 7, and 14 after SRBC immunization. The blood samples were taken from retro-ocular arteria of halothane anesthetized mice. The sera were obtained by blood centrifugation and inactivated at 56℃ for 30min. The total and 2-mercaptoethanol-resistant serum agglutination titers were defined by active hemagglutination test carried out on microplates.

Dosage form

0.1 or 1 or 10mg/kg; i.p. ; 5 or 10 times at 24h intervals

Applications

Bestatin potentiated the humoral response to sheep erythrocytes in mice, resulting in an increased number of plaque-forming cells and 2-mercaptoethanol-resistant anti-SRBC hemagglutinations.
