概述
存在于卫矛科植物雷公藤、南蛇藤等中的抗癌活性成分。该化合物结构载于2006年5月份Cancer Research杂志封面，并证实南蛇藤素通过抑制蛋白酶体活性进而诱发癌细胞凋亡，是有效的蛋白酶体抑制剂，其显著抑制了裸鼠身上前列腺癌的增生。因此，在癌症的预防和治疗方面，南蛇藤素是具有巨大开发潜力的天然蛋白酶体抑制剂。雷公藤红素是一种强力抗氧化，抗发炎剂。它是一种新型的HSP90的抑制剂（扰乱Hsp90/Cdc37复合物），抗癌（抗血管生成 - 抑制VEGFR的表达）;抗氧化剂（抑制脂质过氧化反应）和抗发炎活性（抑制iNOS及炎性细胞因子的生产）。
Information
Celastrol (NSC 70931, Tripterine) is a potentproteasomeinhibitor for the chymotrypsin-like activity of a purified 20S proteasome withIC50of 2.5 μM. Celastrol inducesapoptosisandautophagyvia the ROS/JNK signaling pathway. Celastrol inhibits dopaminergic ne
In vitro
Celastrol at 5 μM inhibits the chymotrypsin-like, PGPH-like, and trypsin-like activities of the purified 20S proteasome by 80%, 5%, and <1%, respectively, whereas at 10 μM, it inhibits these three proteasomal activities by ∼90%, 15%, and <1%, respectively. Celastrol significantly inhibits the proteasomal chymotrypsin activity in PC-3 cells in a concentration-dependent manner. Celastrol at 2.5 μM to 5 μM induces caspase-3 activity by 4.7-fold to 5.5-fold in PC-3 cells. Celastrol (5 μM) treated cells, the levels of the proteasome target proteins, IκB-α and Bax, are increased after 1 hour and further increased to its peak for 4 hours to 12 hours. Celastrol (2.5 μM) treatment induces proteasome inhibition by 40%, as shown by the decreased levels of chymotrypsin-like activity and increased accumulation of ubiquitinated proteins in LNCaP cells. Celastrol (2.5 μM) induces apoptosis in the Celastrol-treated LNCaP cells, as shown by increased levels of caspase-3 activity (up to 3.5-fold), PARP cleavage, and apoptotic morphology. Celastrol (300 nM) is found to suppress LPS-induced production of TNF-alpha and IL-1beta by human monocytes and macrophages. Celastrol (100 nM) also decreases LPS-induced expression of class II MHC molecules by microglia. Celastrol strongly inhibits LPS and IFN-y-induced NO production with IC50 of 200 nM in macrophage lineage cells. Celastrol strongly inhibits TNF-α and IFN-γ-induced NO production with IC50 of 200 nM in endothelial cells. Celastrol (2.5 μM) potentiates the apoptosis induced by TNF and chemotherapeutic agents and inhibits invasion, both regulated by NF-kappaB activation, in KBM-5 cells. Celastrol (2.5 μM) suppresses the expression of TNF induced the expression of gene products involved in antiapoptosis (IAP1, IAP2, Bcl-2, Bcl-XL, c-FLIP, and survivin), proliferation (cyclin D1 and COX-2), invasion (MMP-9), and angiogenesis (VEGF) in KBM-5 cells. Celastrol (5 μM) is found to inhibit the TNF-induced activation of IkappaBalpha kinase, IkappaBalpha phosphorylation, IkappaBalpha degradation, p65 nuclear translocation and phosphorylation, and NF-kappaB-mediated reporter gene expression. Celastrol inhibits proliferating of RPMI 8226, KATOIII, UM-SCC1, U251MG and MDA-MB-231 cells with IC50 of 0.52 μM, 0.54 μM, 0.76 μM, 0.69 μM and 0.67 μM, respectively. Celastrol (1 μM) inhibits growth of RPMI 8226 with a decrease in the levels of cyclin D1 and cyclin E, but concomitant increase in the levels of p21 and p27. Celastrol induces apoptosis in RPMI-8226 cells indicated by the activation of caspase-8, bid cleavage, caspase-9 activation, caspase-3 activation, PARP cleavage and through the down regulation of anti-apoptototic proteins. Celastrol (1 μM) suppresses Akt pathway and activates JNK kinase in RPMI-8226 cells.
In vivo
Celastrol (3 mg/kg) results in significant inhibition (up to 70%) of tumor growth in male nude mice bearing PC-3 tumors, associated with increased p27 levels and Bax level. Celastrol (3 mg/kg) results more apoptotic tumor cells with the appearance of various PARP cleavage fragments in tumor of male nude mice bearing PC-3 tumors. Celastrol (3 mg/kg) causes 35% of tumor inhibition, associated with decreased proteasome activity and decreased expression of AR protein in nude mice bearing C4-2B tumors. Celastrol (3 mg/kg) is found to suppress strongly joint swelling and other manifestations of adjuvant arthritis in mice. Celastrol (0.2 mg/kg) significantly improves the performance in memory, learning and psychomotor activity tests in rats.
