一般描述

嘌呤霉素，也称杆菌肽或嘌啉霉素盐酸盐，是一种氨基核酸酶抗生素和蛋白质合成抑制剂。它是由土壤放线菌白黑链霉菌（Streptomyces alboniger）通过一系列酶促反应合成。嘌呤霉素有效抑制原核和真核细胞，其作用原理是干扰RNA功能，从而抑制蛋白质合成。它也充当氨基肽酶和脑啡肽酶的抑制剂。嘌呤霉素可以使细菌、原生动物、水藻和哺乳动物细胞的生长迅速停止，但是含pac基因的细胞有耐药性。 pac基因的基因产物是嘌呤霉素-N-乙酰基转移酶，这种酶通过乙酰化反应使嘌呤霉素失活。

嘌呤霉素与tRNA的含氨基末端结构相似，这一特性令其在蛋白质合成过程中进入核糖体，结合新生多肽链，并使链的延长停止。嘌呤霉素广泛用于细胞培养，可作为以耐嘌呤霉素基因转化的细胞的选择剂。

应用

嘌呤霉素是一种氨基核苷酸抗生素，衍生自白黑链霉菌。 它可以选择包含抗性基因嘌呤霉素 N-乙酰基转移酶（PAC）的细胞。 它被用在兔模型中，研究处理后的血管平滑肌细胞的生存能力。 嘌呤霉素用在体细胞克隆和胚胎移植后产生增强的绿色荧光蛋白（EGFP）转基因仔猪。

生化/生理作用

作用机制：嘌呤霉素通过提前终止链来抑制蛋白质合成，作为氨基酰基-tRNA 的 3′ 末端的类似物起作用。嘌呤霉素还可作为二肽基肽酶 II（丝氨酸肽酶）和胞质溶胶丙氨酰氨基肽酶的可逆抑制剂起作用。

耐药性机制：嘌呤霉素乙酰转移酶是有效的抗性基因。

抗菌谱：该产品对革兰氏阳性微生物有活性，对耐酸杆菌的活性较低，对革兰氏阴性微生物的活性更低。 嘌呤霉素可以防止细菌、原生动物、藻类和哺乳动物细胞的生长，并且起效迅速，可在 2 天内杀死 99％ 的细胞。

特点和优势

  • 适用于多种研究应用的优质抗生素
  • 抗生素和蛋白质合成抑制剂
  • 有效抑制原核和真核细胞
  • 通过干扰RNA功能抑制蛋白质合成
  • 常用作细胞生物学研究中的选择剂

制备说明

将该产物以 10 mg/mL 的浓度浓缩在水中。已在转染了 pac 耐药基因的 HeLa 细胞上测试了其生长抑制和细胞选择的能力。
