Methyl 12-methyltridecanoate ((R)-betaxolol hydrochloride), a biosurfactant derived from Brevibacterium casei LS14, enhances the biocompatibility of functionalized silver nanoparticles in vivo [1].

Methyl 12-methyltridecanoate ((R)-betaxolol hydrochloride) (最高浓度100 μg/ml，作用时间72小时) 能有效降低纳米银引起的斑马鱼胚胎死亡及其他生理异常现象[1]。同一条件下，该化合物还能减缓纳米银在斑马鱼胚胎中引发的ROS介导的氧化应激响应和细胞凋亡过程[1]。
