包装规格:10mg 250mg in glass bottle
产品简介:一种内源性代谢产物。 Mercaptobenzothiazole is an organosulfuric compound used in rubber vulcanization. It has been classified as a human carcinogen.
溶解性:DMSO:100 mg/mL (597.91 mM; 超声助溶)
储备液保存:-80°C, 6 months; -20°C, 1 month。
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 (14.95 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(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;再向上述体系中加入50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→ 90% Corn Oil Solubility: ≥ 2.5 mg/mL (14.95 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。 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。 注:工作液建议您现用现配,当天使用。 <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。
靶点:Human Endogenous Metabolite
体外研究:2-Mercaptobenzothiazole (1,5,25 μM; 24h) 使 AhR 激活,AhR,CYP1A1,CYP1B1 和细胞转移标志物 MMP1 的 mRNA 和蛋白表达上 调 (qPCR, WB) ,促进 T24 细胞侵袭 (细胞侵袭实验)。 2-Mercaptobenzothiazole (10-5M, 5 x 10-6M) 非竞争性抑制多巴胺 β-羟化酶的百分率为72% 和47%。
体内研究:2-Mercaptobenzothiazole (500, 250, 125, 62.5, 31 g/L) 在非洲爪蟾幼虫中抑制甲状腺激素合成引起甲状腺滤泡细胞肥大、增生和弥漫性肥大等组织学反应延缓变质发育。 2-Mercaptobenzothiazole (750 和 1,500 mg/kg; 一周五次; 103 周; 灌胃) 对雄性F344/N 大鼠具有致癌活性,表现为单核细胞白血病、胰腺腺泡细胞腺瘤、肾上腺嗜铬细胞瘤和包皮腺腺瘤或癌发病率增加。对雌性 F344/N 大鼠具有致癌活性,表现为肾上腺嗜铬细胞瘤和垂体腺瘤发病率增加。2-Mercaptobenzothiazole (300 mg/kg, i.p.) 有效阻断大鼠心肌中外源性多巴胺转化为去甲肾上腺素,进而抑制其合成。
细胞实验:Cell Invasion Assay Cell Line:T24 Concentration:1, 5, 25 μM; 1 μM AhR antagonist (SR1) co-incubation as MMP1 control. Incubation Time:24 h Result: Increased the cell invasion rate, which was decreased after co-incubation with SR1. Western Blot Analysis Cell Line:T24 Concentration:1, 5, 25 μM; 1 μM SR1 co-incubation as MMP1 control. Incubation Time:24 h Result:Increased protein expression of AhR, CYP1A1, CYP1B1 and cell metastasis marker MMP1. Real Time qPCR Cell Line:T24 Concentration:1, 5, 25 μM Incubation Time:24 h Result:Increased mRNA expression of AhR, CYP1A1, CYP1B1 and cell metastasis marker MMP1.
动物实验:Animal Model: NF51, NF54 (Xenopus laevis larvae) Dosage:500, 250, 125, 62.5, and 31 g/L,continuously exposed, 21days for NF51; 500, 250, 125, 62.5,and 31 g/L, continuously exposed, 7 days for NF54. Administration:Exposure Result:Delayed the development of the 21-day group but did not affect the 7-day group. Caused thyroid histological changes, including hypertrophy, proliferation, and colloid depletion of follicular cells in a concentration-dependent manner; increased thyroid iodine levels; and increased NIS gene expression in thyroid tissue in a concentration-dependent manner. Animal Model: F344/N rats and B6C3F1 mice Dosage:750 and 1,500 mg/kg, 13 weeks; 0,375 and 750 mg/kg for mice and male rats, 0, 188 or 375mg/kg for female rats, 5 days a week, 103 weeks. Administration:i.g. Result:Caused cancer in rats, and even low doses caused cancer in male mice. Animal Model: CF-1 male mice, Upjohn Sprague-Dawley male rats. Dosage:300 mg/kg Administration:Intraperitoneal injection (i.p.) Result:Caused the mice to have a depression state after 1 and 2 hours, when norepinephrine levels dropped to about 60% of the control group. Blocked the conversion of dopamine to newly synthesized noradrenaline and physical activity decreased in rats.
