Apamine

产品介绍

Apamin (Apamine) 是在蜂毒素中发现的一种 18 个氨基酸的肽类神经毒素，是一种Ca²⁺激活的K⁺(SK) 通道的特异性和选择性的阻断剂，具有抗炎和抗纤维化的作用。

生物活性

Apamin (Apamine) is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom), is known as a specifically selective blocker ofCa²⁺-activatedK⁺(SK) channels and exhibits anti-inflammatory and anti-fibrotic activity^[1].

IC₅₀& Target

K⁺channel^[1]

体外研究
(In Vitro)

Apamin (0.5-2 μg/mL; 24 hours; HSC-T6 cells) treatment markedly reduces the expression of α-SMA in the TGF-β1-induced HSC-T6 cells. Apamin treatment abrogats the activation of p-Smad2/3 and Smad4 induced by TGF-β1^[1].

Western Blot Analysis^[1]

Cell Line:	HSC-T6 cells
Concentration:	0.5 μg/mL, 1 μg/mL and 2 μg/mL
Incubation Time:	24 hours
Result:	Markedly reduced the expression of α-SMA in the TGF-β1-induced HSC-T6 cells. Abrogated the activation of p-Smad2/3 and Smad4 induced by TGF-β1.

体内研究
(In Vivo)

Apamin (0.1 mg/kg; intraperitoneal injection; twice a week; for 4 weeks; C57BL/6 male mice) treatment results in decreased liver injury and proinflammatory cytokine levels. Apamin suppresses the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-fed mice^[1].

Animal Model:	8-week-old C57BL/6 male mice (20-25 g) with DDC feeding^[1]
Dosage:	0.1 mg/kg
Administration:	Intraperitoneal injection; twice a week; for 4 weeks
Result:	Resulted in decreased liver injury and proinflammatory cytokine levels. Suppressed the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the DDC-fed mice.
