生物活性

ML351 is a potent and highly specific 15-LOX-1 inhibitor with an IC50 of 200 nM. ML351 shows excellent selectivity (>250-fold) versus the related isozymes, 5-LOX, platelet 12-LOX, 15-LOX-2, ovine COX-1, and human COX-2[1].?ML351 prevents dysglycemia and reduces β-cell oxidative stress in nonobese diabetic mouse model of T1D[2].

ML351 (0-48 mg/kg;在 STZ 系列開始之前和最后一次 STZ 劑量后 5 天結(jié)束) 在 STZ β 細(xì)胞損傷模型中防止糖尿病發(fā)展。與對照組相比,24 mg/kg (M24) + STZ 的 ML351 顯示出顯著更少的體重減輕。M24 顯示幾乎完全防止高血糖。但到研究的第 9 天,M48 和 M0 表現(xiàn)出明顯的高血糖癥并且 GTT 顯著受損[2]。
ML351 (腹膜內(nèi)注射;0-24 mg/kg;每日一次,持續(xù) 2 周) 導(dǎo)致改善血糖控制并顯著減少胰島炎。NOD 小鼠中 β 細(xì)胞死亡的減少被認(rèn)為可以減少胰島炎,這可能是通過減輕垂死的 β 細(xì)胞釋放的趨化信號來實現(xiàn)的。與 NOD + M0 動物相比,NOD + M24 動物表現(xiàn)出更好的血糖控制[2]。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
