NS-1619 是 Ca2+激活的 K+(BK) 通道的激活剂。 NS-1619 是一种高效的松弛剂,在血管和其他组织的几个平滑肌中的 EC50约为 10 – 30 μM。NS1619抑制A2780卵巢癌细胞增殖并诱导细胞凋亡 (apoptosis)。
生物活性 | NS-1619 is an opener of large conductance Ca2+-activated K+(BK) channel. NS-1619 is a highly effective relaxant with an EC50of about 10 – 30 μM in several smooth muscles of blood vessels and other tissues[1]. NS1619 inhibits proliferation and inducesapoptosisin A2780 ovariancancercells[2]. |
体外研究 (In Vitro) | NS1619 (5, 10, 30, 50, and 100 μM) inhibits the proliferation of A2780 cells in a dosage and time dependent manner IC50=31.1 μM for 48 h pretreatment[2]. NS1619 (30 μM) exhibits augmenting effect on whole cell IKin human ovarian cancer cells A2780[2]. NS1619 (10, 30, 50, and 100 μM) increases levels of p53, p21Cip1and Bax proteins in A2780 cells[2]. DNA content of A2780 cells was significantly decreased after 36 and 48 h of pretreatment. The breakdown of DNA results in death of the tumor cells[2].
Cell Viability Assay[2] Cell Line: | The human ovarian cancer cell line A2780 | Concentration: | 5, 10, 30, 50, and 100 μM | Incubation Time: | 48 hours | Result: | Inhibited cell growth in a time and concentration-dependent manner, IC50=31.1 μM. Proliferation was significantly inhibited at concentrations of NS1619 higher than 10 μM. |
Western Blot Analysis[2] Cell Line: | A2780 cells | Concentration: | 0, 5, 10, 30, 50, and 100 μM | Incubation Time: | 48 hours | Result: | Expression of p53, p21, and Bax in A2780 cells was significantly increased in comparison with control. |
Western Blot Analysis[2] Cell Line: | A2780 cells | Concentration: | 30 μM | Incubation Time: | 36 and 48 hours | Result: | DNA content of A2780 cells was significantly decreased after 36 and 48 h of pretreatment. The breakdown of DNA results in death of the tumor cells. |

体内研究 (In Vivo) | Opening of KCachannels with NS-1619 (1 mg/kg; i.p.) can delay protection in mouse hearts[3].
Animal Model: | Adult male outbred ICR mice[3] | Dosage: | 1 mg/kg | Administration: | Pretreated i.p. 24 h before I/R | Result: | Pretreatment induced delayed protection 24 h later. Resulted in significant cardioprotection 24 h later, i.e., infarct size was reduced from 38.8 ± 3.7% to 19.8 ± 2.9%. |
