Description of Forsythoside B

Forsythoside B는 전통 중국 의학 식물인 Forsythia suspensa의 잎에서 분리된 페닐에탄올 글리코사이드입니다. 이 물질은 여러 가지 생물학적 활성을 가지고 있고 염증성 질환을 치료하고 혈액 순환을 촉진하는 데 사용할 수 있다. Forsythoside B는 폐렴볼린을 표적으로 삼아 폐렴쌍구균의 독성을 줄일 수 있다[2]. Forsythoside B는 아쿠아시스균과 아나토박터 파스퇴리균에 대해 효과적인 항균 활성을 보인다[3].

체외 실험에서 Forsythoside B(1, 2.5µM)로 전처리된 BV-2 세포를 3시간 동안 처리하면 LPS로 인한 세포 내 IL-6, TNF-α, iNOs, NO 및 IL-1β의 증가를 현저하게 억제한다[4]. Forsythoside B(40, 80, 160μg/mL)로 전처리된 RAW 264.7 대식 세포를 1시간 동안 처리하면 LPS로 인한 세포 내 PGE2, COX-2, 아초산염 및 iNOS의 증가를 크게 억제한다[5].

체내 실험에서 Forsythoside B(40mg/kg)를 맹장 결찰및 천공(CLP)으로 유도된 패혈증을 가진 쥐에게 정맥 주사 투여했을 때 혈청 TNF-α, IL-6, HMGB1, 골수세포에 발현된 유발 수용체(TREM-1), 내독소 수준을 감소시키고 IL-10 수준을 상향 조절하고 폐, 간, 소장에서 과산화물 농도를 감소시켰다[6]. Forsythoside B(10, 40mg/kg)를 척수 손상(SCI)을 가진 쥐에게 복강 주사 투여했을 때 염증 인자 수준을 유의하게 감소시키고 별세포 섬유화를 억제하고 신경세포 사멸과 조직 결손을 줄이고 운동 기능 회복을 촉진했다[7].

Protocol of Forsythoside B

세포 실험 [1]:

세포 라인

BV-2 세포

제조 방법

96웰 판에 종자BV-2 세포를 1μM과 2.5μM Forsythoside B 또는 PBS로 3시간 동안 전 저리한 후 DMEM에 녹인 1μg/mL LPS와 함께 24시간 동안 공동 배양했습니다.

반응 조건

1, 2.5µM; 3시간 동안

응용 분야

BV-2 세포에서 LPS로 유도된 IL-6, TNF-α, iNOs, NO 및 IL-1β의 증가는 Forsythoside B의 사전 배양에 의해 강력히 억제되었습니다.

동물 실험 [2]:

동물 모형

Sprague-Dawley 쥐

제조 방법

맹장 결찰 및 천공(CLP)을 받은 쥐 40마리를 4개의 소그룹으로 나누었고 각 그룹당 10마리씩 분류되었습니다: (i) CLP(모델 그룹); (ii) Forsythoside B 40mg/kg 그룹; (iii) Imipenem 20mg/kg 그룹; (iv) Imipenem 20mg/kg + Forsythoside B 40mg/kg 그룹. 모든 쥐는 CLP 후 1시간과 13시간에 정맥 주사(i.v.)로 Forsythoside B를 2회만 투여받았고 CLP 후 20시간에 소장, 간, 폐를 채취하고 생화학 분석을 위해 사용되었습니다.

제형

40mg/kg; i.v.

응용 분야

Forsythoside B는 혈청 TNF-α, IL-6, HMGB1, 골수세포에 발현된 유발 수용체(TREM-1) 및 내독소 수준을 감소시킬 수 있고 혈청 IL-10 수준은 상향 조절되고 폐, 간 및 소장에서 미숫물 과산화효소(MPO) 농도가 감소합니다.
