产品介绍
Eplontersen 是一种三触角的、N-乙酰半乳糖胺 (GalNAc3)-缀合的反义寡核苷酸,能够靶向 甲状腺素运载蛋白 TTR 的 mRNA,抑制变体和野生型 TTR 产生。错误折叠的 TTR 诱导心脏和周围神经的淀粉样原纤维形成,并介导淀粉样 TTR (ATTR) 蛋白变性疾病。
生物活性

Eplontersen is a triantennary N-acetyl galactosamine (GalNAc3-7a)-conjugated antisense oligonucleotide targetingtransthyretin (TTR)mRNA to inhibit production of both variant and wild-type TTR protein. Misfolded TTR induces amyloid fibrils formation in the heart and peripheral nerves, leads to amyloid TTR (ATTR) amyloidosis diseases[1][2][3].

IC50& Target

TTR[1], asialoglycoprotein receptor[3]

体外研究
(In Vitro)

Eplontersen mediates N-acetylgalactosamine moiety targeting the oligonucleotide to cells bearing an asialoglycoprotein receptor[3].

体内研究
(In Vivo)

Eplontersen (682884) (0.6, 2, 6 mg/kg; s.c.; once a week for 3 weeks) inhibits TTR protein expression in a dose-dependent manner in vivo, without affecting normal growth in transgenic C57BL/6 mice expressing human transthyretin (TTR)[3].

Animal Model:Transgenic C57BL/6 mice expressing human transthyretin (TTR) (8-week-old)[3]
Dosage:0.6, 2, 6 mg/kg
Administration:Subcutaneous injection; once a week for 3 weeks; performed tail bleeds at various time point; sacrificed mice 72 h following the final administration
Result:Decreased TTR mRNA level to 15%, and reduced plasma TTR protein levels to 21% at 6 mg/kg on day 17 after injection.
Showed no significant effect on plasma ALT and AST level, no inhibition on body weight, organ weight, spleen weight, and kidney weight as well.
