一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
2-APB是Ins(1,4,5)P3诱导Ca2+释放的拮抗剂,其IC50值为42 μM[1]。
Myo-Ins(1,4,5)P3受体(IP3R)介导内部Ca2+动员。IP3R参与钙波和钙振荡的产生。
2-APB是Ins(1,4,5)P3诱导Ca2+释放的拮抗剂。2-APB抑制Ins(1,4,5)P3诱导的大鼠小脑微粒体Ca2+释放,其IC50值为42 μM。在人类血小板和中性粒细胞中,将2-APB加入到细胞外液中可以抑制凝血酶诱导的细胞内Ca2+增加。此外,2APB抑制血管紧张素Ⅱ(AⅡ)诱导的胸主动脉收缩[1]。在HEK-293细胞中,细胞外的2-APB阻断人TRPC5通道,其IC50值为20 μM。此外,2-APB阻断TRPC6和TRPC3通道。在过度表达TRPC5的细胞中,2-APB抑制细胞增殖[2]。在小鼠胰腺腺泡细胞中,低浓度的2-APB可以显著抑制钙库调控的钙内流。在透化的腺泡细胞中,高浓度的2-APB抑制直接刺激的Ca2+释放和InsP3诱导的Ca2+释放[3]。
在I/R引起睾丸损伤的大鼠中,2-APB显著增加超氧化物歧化酶(SOD)、总抗氧化能力(TAC)和谷胱甘肽(GSH),同时减少丙二醛(MDA)和DNA片段,这表明2-APR具有抗凋亡和抗氧化作用[4]。

Cell experiment:[1] | |
Cell lines | Mouse pancreatic acinar cells |
Reaction Conditions | 10 ~ 100 μM 2-APB |
Applications | In mouse pancreatic acinar cells, 2-APB significantly inhibited store-operated Ca2+(SOC) channel-mediated Ca2+entry at low concentrations (~ 30 μM). At higher concentrations (~ 100 μM), 2-APB exerted multiple paradoxical effects including inhibition of InsP3-induced Ca2+release and direct stimulation of Ca2+release. |
Animal experiment:[2] | |
Animal models | Adult male Sprague-Dawley rats, 250 ~ 300 g |
Dosage form | 2 or 4 mg/kg Administered intraperitoneally |
Applications | In rats with ischemia-reperfusion (I/R) induced testicular injury, 2-APB significantly increased mean levels of superoxide dismutase, total antioxidant capacity and glutathione, and reduced mean malondialdehyde and DNA fragmentation levels, which suggested the antiapoptotic and antioxidative effects of 2-APB. |
