产品描述

Concanamycin A是液泡型ATP酶(V-ATP酶)的特异性抑制剂,IC50值为10 nM [1]。

液泡型ATP酶(V-ATP酶)在透明细胞中表达,可以酸化附睾的内腔,这对于男性生育能力是必不可少的。更重要的是,它可以引起质子在细胞外基质的积累,这对于在酸性微环境中维持细胞内pH具有重要作用。有报道称,在几种恶性肿瘤中,V-ATP酶参与酸化实体瘤周围的微环境及诱导肿瘤浸润/多药耐药性 [2]。

Concanamycin A(CMA)是特异性的V-ATP酶抑制剂,与之前报道的V-ATP酶抑制剂SS33410不同。在口腔鳞状细胞癌(OSCC)细胞系(MRSK81-5、SAS和HSC-4)中,低浓度CMA诱导肿瘤细胞的凋亡 [3]。使用concanamycin A预处理结直肠癌细胞系可以通过阻断V-ATP酶诱导的内含体酸化,显著增强肿瘤坏死因子(TNF)相关凋亡诱导配体(TRAIL)诱导的细胞凋亡 [4]。Concanamycin A通过抑制前列腺癌细胞系C4-2B细胞中的V-ATP酶,可以减少80%肿瘤浸润 [5]。

研究表明,Concanamycin A 通过穿孔素介导的细胞毒性途径,可以有效抑制CTL细胞毒性 [6]。
