[体外研究]

Bestatin增强ATRA诱导的分化并抑制ATRA驱动的ATRA敏感的APL NB4细胞中p38 MAPK的磷酸化。 Bestatin不能逆转ATRA抗性APL MR2细胞中的分化阻滞。 CD13与抗CD13抗体WM-15结合导致p38 MAPK磷酸化,降低Bestatin对p38 MAPK磷酸化的抑制作用,并完全消除了Bestatin对ATRA诱导NB4细胞分化的增强作用[2]。由于细胞生长速率降低和细胞分裂频率降低,Bestatin(600μM)处理的细胞在细胞周期中进展缓慢。 Bestatin抑制D. discoideum中有丝分裂的频率和固有的多核,并且在0-600μM时对D. discoideum细胞没有细胞毒性。 Bestatin抑制PsaA-GFP和GFP表达细胞裂解液中的氨肽酶活性分别为对照的69.39％±10.5％和39.93％±18.7％[4]。

[体内研究]

与糖尿病载体治疗的小鼠相比,Bestatin(20μM)显着降低糖尿病小鼠中的CD13表达并导致MMP-9特异性凝胶分解带密度的显着抑制。 Bestatin治疗显着抑制糖尿病小鼠中VEGF和乙酰肝素酶的表达。玻璃体腔内bestatin治疗显着下调糖尿病小鼠视网膜中HIF-1α和VEGF的表达。此外,玻璃体内bestatin治疗显着抑制了糖尿病小鼠视网膜中乙酰肝素酶的上调表达[1]。在对SRBC的抗原强化的体液应答之前,Bestatin(10,1和0.1mg/kg,ip)处理导致产生溶血性抗SRBC抗体(PFC)和2-ME抗性血清血凝素滴度的脾细胞数量增加。 (剂量为0.1 mg/kg)。注射环磷酰胺后隔天给小鼠服用5次Bestatin(1和0.1 mg/kg)不会改变药物对PFC数量的抑制作用,甚至导致剂量下总抗SRBC血凝素的进一步减少抗原刺激后第7天1 mg/kg [3]。

[激酶实验]

收获细胞，洗涤并在NP-40裂解缓冲液（50mM Tris-HCl [pH 7.5]，150mM NaCl，0.5％NP-40）中裂解。使用Bradford测定法定量总细胞蛋白质，并制备1mg / mL蛋白质等分试样。将10微升总细胞蛋白与290μL底物溶液（0.1mg / mL二硫苏糖醇[DTT]，0.1mg / mL白蛋白和1mM丙氨酸-β-萘酰胺）混合。在15和30分钟后进行荧光测量（340nm激发，400nm发射）。 15和30分钟测量之间的线的斜率用于表示氨肽酶活性。在荧光氨基肽酶测定之前，将总细胞蛋白与bestatin，amastatin，嘌呤霉素，EDTA和/或ZnCl2一起预孵育20分钟。

[细胞实验]

将生长的细胞（1×10 6至2×10 6个细胞/ mL）稀释至1.0×10 3个细胞/ mL，并转移（3mL）到12孔多孔板（2.5cm直径/孔）中的孔中。用0,10,50,100,300或600μMBidatin处理细胞，并使其在21℃下以180rpm振荡培养48小时。血细胞计数器用于在0,24和48小时后测量细胞密度。

[动物实验]

将Bestatin溶解在PBS中。在SRBC免疫之前，将药剂（10,1和0.1mg / kg的剂量）腹膜内注射到非环磷酰胺处理的小鼠中，以24小时间隔注射5或10次。在最后一剂bestatin后24小时免疫小鼠。在SRBC免疫前12天，以350mg / kg的剂量单次腹膜内注射环磷酰胺诱导药理学免疫抑制。在SRBC免疫前，将剂量为1和0.1mg / kg的Bestatin以48小时间隔腹膜内注射环磷酰胺免疫抑制小鼠5次，或以24小时间隔注射10次。在环磷酰胺后24小时施用第一剂bestatin，而在SRBC免疫前24小时注射最后一剂药物。
