Bezisterim
Based on 1 Customer Validation
Bezisterim (HE 3286; NE-3107) is a synthetic derivative of a natural anti-inflammatory steroid, β-AET. Bezisterim is an orally active partial NF-κB inhibitor. HE3286 reduces proinflammatory signals, including IL-6 and matrix metallopeptidase 3. Bezisterim freely penetrates the blood brain barrier in mice. Bezisterim can be used for the research of the ulcerative colitis, arthritis, experimental autoimmune encephalomyelitis. Bezisterim is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Biological Activity
NF-κB[3]
Bezisterim attenuates NF-κB phosphorylation, but not influences IκB phosphorylation of LPS-induces (100 ng/mL; 0-2 hours) murine macrophages[3].
Bezisterim (100 nM, overnight) partially blocks the activation of IKK, JNK, p38, and ERK of LPS-induces (100 ng/mL; 0-2 hours) murine macrophages[3].

Bezisterim (40 mg/kg; intraperitoneal injection; daily for 40 days) suppresses inflammation, reduces demyelination and axonal loss, and promotes RGC survival during experimental optic neuritis of experimental autoimmune encephalomyelitis mice[2].
Bezisterim (80?mg/kg; 0-24h) freely penetrates the BBB in male CD-1 mice[4].
Bezisterim (40 mg/kg; gavage; twice-daily for 4 days) increases the numbers of tyrosine hydroxylase-positive cells and decreases the numbers of damaged neurons in Parkinson's disease mice[4].
