- 產(chǎn)品描述: ANA-12 是一種選擇性 TrkB 拮抗劑,對(duì)高親和位點(diǎn)和低親和位點(diǎn)的Kd 分別為10 nM 和 12 μM
- 靶點(diǎn): TrkB:10 nM(Kd);Trkreceptor
- 體外研究:
ANA-12可選擇性直接與TrkB受體結(jié)合,抑制TrkB下游通路,而不改變TrkA和TrkC功能。在nnr5 PC12-TrkB細(xì)胞中,10 nM的 ANA-12可防止腦源性神經(jīng)營(yíng)養(yǎng)因子(BDNF)介導(dǎo)的神經(jīng)突增生。在DRG神經(jīng)元中,ANA-12可消除BDNF增加內(nèi)向電流的作用
- 體內(nèi)研究:
在成年C57BL6/129SveV F1s小鼠中,ANA-12 (0.5 毫克/千克,腹腔注射)降低腦部TrkB活性,減輕焦慮和抑郁相關(guān)行為,而不影響神經(jīng)元的存活。在雄性C57BL/6小鼠體內(nèi),ANA-12 (0.5 毫克/千克,腹腔注射)對(duì)脂多糖誘導(dǎo)的抑郁行為顯示出抗抑郁作用。在雄性Sprague-Dawley大鼠中,ANA-12 (3微克/劑) 阻斷孤束內(nèi)側(cè)亞核(mNTS) BDNF減少進(jìn)食的作用。在雄性野生型小鼠中,ANA-12逆轉(zhuǎn)酒精攝入,下調(diào)D3受體表達(dá),但在D3R-/-型小鼠中是無(wú)效的。在雄性CocSired大鼠,腹腔注射ANA-12(0.5 毫克/千克)逆轉(zhuǎn)減弱的可卡因自身給藥
- 細(xì)胞實(shí)驗(yàn): Cell lines: nnr5 PC12–TrkA,nnr5 PC12–TrkB,和 nnr5 PC12–TrkC 細(xì)胞 Concentrations: ~100 μM Incubation Time: ~3 天 Method: 分別經(jīng)BDNF (1 nM)、NGF (2 nM)和NT-3 (10 nM)處理后的nnr5 PC12–TrkB、–TrkA和–TrkC細(xì)胞用于分子對(duì)神經(jīng)突增生調(diào)節(jié)的評(píng)估。每個(gè)計(jì)數(shù)區(qū)域中,突觸長(zhǎng)度大于2倍細(xì)胞直徑的細(xì)胞的數(shù)量通過(guò)顯微鏡觀察(每孔兩個(gè)視野,每組三孔)測(cè)定。每24 h計(jì)數(shù)一次,進(jìn)行三天
- 動(dòng)物實(shí)驗(yàn): Animal Models: 成年 C57BL6/129SveV F1s 小鼠 Dosages: 0.5 毫克/千克 Administration: 腹腔注射
