生物活性 | Benzethonium chloride 是有效的neuronal nicotinic acetylcholine receptors (nAChRs)(神经元烟碱型乙酰胆碱受体)抑制剂,抑制α4β2 nAChRs和α7 nAChRs,IC50分别为49 nM 和 122 nM。[1] |
In Vitro | Benzethonium chloride以混合竞争性和非竞争性的方式抑制α7 nAChRs中乙酰胆碱的应答,但这两种方式都不存在电压依赖响应或者使用依赖响应。[1] Benzethonium chloride降低细胞活性,其IC50在FaDu中为3.8 μM ,在NIH 3T3中为42.2 μM , 在C666-1中为5.3 μM , 而在GM05757中为 17.0 μM 。Benzethonium chloride (9 μM)在FaDu细胞中12小时后会诱导细胞凋亡,并且激活胱天蛋白酶。 [2] |
In Vivo | Benzethonium chloride (5 mg/kg)切断FaDu细胞肿瘤形成能力,延缓移植瘤的生长,并结合局部肿瘤放射疗法来治疗SCID小鼠体内的FaDu肿瘤。 [2] |

动物实验 | Briefly, FaDu cells were seeded (0.3 × 106?per T-25 flask), allowed to incubate for 1 day, and then treated with benzethonium chloride or vehicle alone (0.1% DMSO) as indicated. After 24 hours, all floating and adherent cells (using trypsin) were collected and resuspended in growth medium at a concentration of 106/mL. DiIC1(5) (40 nmol/L final concentration) and indo-1 AM (2 μmol/L final concentration) were added to the cell suspensions. The cells were incubated at 37°C for 25 minutes and propidium iodide (1 μg/mL) was then added. The cells were analyzed by flow cytometry using a Coulter Epics Elite [Beckman Coulter; DiIC1(5) excitation 633 nm, 675 ± 20 nm bandpass; indo-1 AM excitation 360 nm, emission ratio 405/525 nm].[2] |
细胞实验 | FaDu cells were injected into the left gastrocnemius muscle of SCID mice (2.5 × 105?in 100-μL growth medium per mouse). The leg diameter of a normal mouse was <7 mm. when the tumor-plus-leg diameter reached 7.25 mm, mice were randomized into one of following groups: (a) pbs, (b) benzethonium chloride, (c) radiation-plus-pbs, and (d) radiation-plus-benzethonium chloride. on days 1 to 5, given i.p. injection (100 μl bolus) daily either pbs or chloride (5 mg> |
