| 包装规格: | 2mg 5mg 10mg 25mg 50mg 100mg in glass bottle |
| 产品简介: | ICA-121431 是一种纳摩尔级别强效广谱电压门控钠通道 (Nav) 阻滞剂,对人 Nav1.1 和 Nav1.3 亚型具有等效选择性,IC50 值分别为 13 nM 和 23 nM。ICA-121431 对Nav1.2 的抑制作用较弱 (IC50=240 nM),对 Nav1.4、Nav1.6、抗TTX 的人 Nav1.5、Nav1.8 通道表现出大于 1000 倍的选择性(IC50s >10 µM)。 |
| 溶解性: | 溶于DMSO ( ≥44 mg/mL) |
| 储备液保存: | -80°C, 2 years -20°C, 1 year |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% saline Solubility: ≥ 2.5 mg/mL (5.56 mM); Clear solution 此方案可获得 ≥ 2.5 mg/mL (5.56 mM,饱和度未知) 的澄清溶液。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;向上述体系中加入50 μL Tween-80,混合均匀;然后继续加入 450 μL生理盐水定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% (20% SBE-β-CD in saline) Solubility: 2.5 mg/mL (5.56 mM); Suspended solution; Need ultrasonic 此方案可获得 2.5 mg/mL (5.56 mM) 的均匀悬浊液,悬浊液可用于口服和腹腔注射。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中,混合均匀。 3、请依序添加每种溶剂: 10% DMSO→90% corn oil Solubility: ≥ 2.5 mg/mL (5.56 mM); Clear solution 此方案可获得 ≥ 2.5 mg/mL (5.56 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。 以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |

| 体外研究: | ICA-121431 interacts with human Nav1.3 and the amino acid residues that may define selectivity for this channel over other related Nav channels, including Nav1.7 and Nav 1.5. Data generated using conventional patch clamp electrophysiological recording using a pulse protocol whereby a 20-ms test pulse is preceded by an 8-s step to a voltage that inactivated half of the channels. ICA-121431 is against Wild type hNav1.3 hNav1.5 hNav1.7 with IC50s of 0.013 µM, >30 µM, 12 µM, respectively. ICA-121431 is against hNav channels with point mutations,shows hNav1.3 M1 (S1510Y), hNav1.3 M2 (R1511W), hNav1.3 M3 (E1559D), hNav1.3 M1,3 (S1510Y/E1559D), hNav1.3 M2, 3 (R1511W/E1559D), hNav1.3 M1, 2, 3 (S1510Y/R1511W/E1559D), and hNav1.7 M1, 2, 3 (Y1537S/W1538R/D1586E) with IC50 values of 0.1 µM, 0.37 µM, 1.1 µM, 1.3 µM, 1.9 µM, 11.6 µM, 0.032 µM, respectively. ICA-121431 is against hNav channels with point mutations,shows hNav1.3/hNav1.5 S1-S4, hNav1.3/hNav1.5 S3-S4, hNav1.3/hNav1.5 S5-S6, hNav1.3/hNav1.7 S1, hNav1.3/hNav1.7 S2, hNav1.3/hNav1.7 S3-S4, and hNav1.3/hNav1.7 S5-S6 with IC50 values of 0.083 µM, 1.2 µM, 11 µM, 2.0 µM, 0.045 µM, 0.030 µM, 0.30 µM, 1.0 µM, and 0.024 µM, respectively. |
