描述 | 乳酸红霉素是一种由放线菌红霉素链霉菌产生的大环内酯类抗生素,具有广谱抗菌活性。乳糖酸红霉素结合细菌50S核糖体亚基,通过阻断转肽和/或易位反应抑制RNA依赖性蛋白质合成,而不影响核酸的合成[1][2]。乳糖酸红霉素在不同的研究领域也表现出抗肿瘤和神经保护作用[3][4]。 |

体外研究 | 乳糖酸红霉素抑制恶性疟原虫的生长,IC50和IC90值分别为58.2μM和104.0μM[1]。乳糖酸红霉素(10μM,100μM;24小时,72小时)具有抗氧化和抗炎作用,抑制4-HNE(p<0.01)和8-OHdG(p<1.01)的积累,显著降低Iba-1(p<2.01)及TNF-α(p<3.01)表达[4]。细胞存活率测定[4]细胞系:胚胎原代皮质神经元(来自17日龄Sprague-Dawley大鼠的大脑皮质)浓度:10,100μM孵育时间:24,72小时结果:在3小时缺氧-葡萄糖剥夺(OGD)后,提高了体外培养的神经元细胞的存活率。 |
体内研究 | 乳糖酸红霉素(胃插管;0.1-50 mg/kg;30-120天)可降低肿瘤生长,并延长小鼠的存活时间,剂量为5 mg/kg[3]。乳糖酸红霉素(胃插管;5 mg/kg)即使在接种后120天也能保护小鼠的存活,但50 mg/kg剂量可将荷瘤小鼠的平均存活时间缩短4-5天[3]。乳糖酸红霉素(i.h.单次注射;50 mg/kg)对大鼠脑缺血再灌注损伤模型具有保护作用[4]。动物模型:具有EAC细胞的雌性ddY小鼠(6周龄)或具有P388细胞的CDF小鼠(6周龄)[3]剂量:0.1mg/kg;0.5mg/kg;10mg/kg;30mg/kg;50mg/kg给药:胃插管;30-120天结果:从5mg/kg剂量开始,降低肿瘤生长并延长小鼠的平均生存时间,然而,50mg/kg剂量缩短了荷瘤小鼠的MST。动物模型:雄性Sprague-Dawley大鼠(8周龄,250-300 g)[4]剂量:50 mg/kg给药: |
