一般描述
一种具有细胞渗透性的对称二氢咪唑酰胺化合物，可作为N-SMase（中性鞘磷脂酶）的有效、特异性、非竞争性抑制剂[IC50 = ~ 1 µM，大鼠脑；鞘磷脂的Km ~13 µM]。即使在150 µM下，也不抑制人类A-SMase（酸性鞘磷脂酶）。弱抑制牛蛋白磷酸酶2A和哺乳动物lyso PAF PLC的活性，而未观察到细菌磷脂酰胆碱特异性PLC的抑制。据报道，在20 µM时，可完全保护MCF7乳腺癌细胞中TNF-α或二胺诱导的细胞死亡护。不改变细胞内谷胱甘肽水平或干扰TNF-α或二胺介导的信号传递效应。
一种细胞可渗透的对称二氢咪唑酰胺，可作为中性鞘磷脂酶（N-SMase）的有效性、特异和非竞争性抑制剂（IC50 = 1 µM，大鼠脑N-SMase）。据报道，可在MCF7细胞中抑制肿瘤坏死因子α（TNF-α）诱导的鞘磷脂水解（20 µM时100%抑制）和TNF-α-诱导的细胞死亡。不干扰其他TNF-α-介导的信号事件，如从头神经酰胺合成、NF-κB激活和核转位。对通常因TNF-α而降低的细胞谷胱甘肽水平没有影响。不抑制酸性鞘磷脂酶（A-SMase）或细菌磷脂酰胆碱特异性磷脂酶C（PC-PLC）。显示弱抑制牛蛋白磷酸酶2A (PP2A)和人lyso PAF PLC，一种在体外水解鞘磷脂的酶。

The identification and biological actions of pituitary-derived exosomes remain elusive. This work aimed to validate production of exosomes derived from human and rat pituitary and elucidate their actions.
