Celastrol, Celastrus scandens -CAS 34157-83-0-Calbiochem

产品说明

一般描述

A cell-permeable dienone-phenolic triterpene compound with antioxidant and anti-inflammatory properties. It suppresses LPS-induced release of pro-inflammatory cytokines in macrophages and monocytes (IC₅₀ = 40 nM for IL-1β and IL-1α, 80 nM for IL-6, 110 nM for PEG₂, and 210 nM for IL-8 and TNF-α). Also suppresses LPS-induced NF-κB activation (IC₅₀ = 270 nM) and NO production (IC₅₀ = 230 nM) in RAW264.7 cells. Preferentially inhibits chymotrypsin-like activity of 20S proteasome with an IC₅₀ of 2.5 µM. Shown to inhibit lipid peroxidation induced by ADP and Fe²⁺ in rat liver mitochondria (IC₅₀ = 7 µM). Improves performance in memory, learning, and psychomotor activity in rats. May be useful in minimizing inflammation in Alzheimer′s disease animal models.

Has also been shown to inhibit lipid peroxidation induced by ADP and Fe²⁺ in rat liver mitochondria (IC₅₀ = 7 µM). Significantly improves the performance in memory, learning, and psychomotor activity in rats. May be useful to minimize inflammation in Alzheimer′s disease (AD).
