體外研究
(In Vitro)

Crisaborole (AN-2728) 抑制 PDE4、TNF-α、IL-2、IFN-γ、IL-5 和 IL-10,IC50 值為 0.49、0.54、0.61、0.83、2.4 和 5.3 μM。Crisaborole (AN-2728) 顯示出對(duì) PDE4 催化結(jié)構(gòu)域最有效的活性,但它也顯示出對(duì) PDE1A3、PDE3Cat 和 PDE7A1 的抑制作用。Crisaborole (AN-2728) 抑制 PDE 同工酶 PDE1A3、PDE3Cat、PDE4Cat 和 PDE7A1,IC50 值為 6.1、6.4、0.11 和 0.73 μM[1]。晶體學(xué)表明,苯并氧雜硼與 PDE4 催化結(jié)構(gòu)域中的疏水口袋的相互作用增加了它們對(duì) PDE4 的親和力。這些苯并氧雜硼化合物強(qiáng)烈抑制與 Ps 和 AD[2] 相關(guān)的細(xì)胞因子的分泌。Crisaborole (AN-2728) 是一種局部給藥的含硼抗炎化合物,可抑制 PDE4 活性,從而抑制 TNFalpha、IL-12、IL-23 和其他細(xì)胞因子的釋放[3]

(In Vivo)

Crisaborole (AN-2728) 以 1 mg/耳×2 給藥后,對(duì)佛波醇酯引起的耳水腫有顯著抑制作用 (分別為 78% 和 68%)。療效與地塞米松相當(dāng),表明 Crisaborole (AN-2728) 具有良好的抗炎活性和皮膚滲透性[1]。據(jù)報(bào)道,Crisaborole (AN-2728) 具有良好的耐受性,并證明對(duì)療效標(biāo)志物有顯著影響,其結(jié)果與臨床試驗(yàn)中的陽(yáng)性對(duì)照相當(dāng)[3]。

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.
