NGI-1 (ML414) 是一种有效的寡糖基转移酶 (OST) 抑制剂,直接靶向和阻断 OST 催化亚基 STT3A 和 STT3B 的功能。NGI-1 是一种细胞渗透性抑制剂,可有效降低病毒感染性而不影响细胞活力。
生物活性 | NGI-1 (ML414) is a potentoligosaccharyltransferase (OST)inhibitor, directly targeting and blocking the function of the OST catalytic subunits STT3A and STT3B[1]. NGI-1 is a cell permeable inhibitor and can effectively reduce virus infectivity without affecting cell viability[2]. |

体外研究 (In Vitro) | NGI-1 inhibits the glycosylation of LASV GP mediated by STT3A-OST (in STT3B- and MAGT1-TUSC3- cells) or STT3B-OST (in STT3A- cells) and impaires its proteolytic cleavage in a dose-dependent manner[1]. NGI-1 blocks EGFR N-linked glycosylation in lung adenocarcinoma cells as assessed. In controls EGFR is biotinylated, consistent with its plasma membrane expression, but in NGI-1 treated cells the EGFR is predominantly found in the non-biotinylated intracellular fraction suggesting a change in cellular localization[2].
Western Blot Analysis[1] Cell Line: | STT3A-, STT3B- and MAGT1-TUSC3- cells | Concentration: | 1, 2, 5 μM | Incubation Time: | 36 hours | Result: | Inhibited the glycosylation of LASV GP mediated by STT3A-OST (in STT3B- and MAGT1-TUSC3- cells) or STT3B-OST (in STT3A- cells) and impaired its proteolytic cleavage in a dose-dependent manner. |
