The invention relates to a method for removing phorbol esters from Jatropha curcas seed oil by extraction. The method comprises drying Jatropha curcas seed oil meal obtained from pre-squeezing and leaching processes, grinding into powder, mixing with industrial methanol at a weight ratio of 3.5:1.1 at 30 DEG C for more than 20 min, filtering to separate oil meal and methanol phase, collecting the oil meal and heating to remove residual methanol in the oil meal to obtain detoxicated plant protein; and concentrating the separated methanol phase to obtain phorbol ester product. After removing phorbol esters by methanol extraction, the content of phorbol esters in the oil meal is reduced from 1.78% to 0.014%, so that the oil meal can be used in preparing feed proteins.

The present invention provides an inhibitor of NF-κB, guggulsterone and its analogs. Guggulsterone suppresses NF-κB activation induced by TNF, phorbol ester, okadaic acid, cigarette smoke, H₂O₂ and IL-1β, as well as constitutive NF-κB activation expressed in most tumor cells. One mechanism by which guggulsterone inhibits activation of NF-κB is through suppression of IκBα phosphorylation and IκBα degradation. NF-κB-dependent gene transcription is modulated by guggulsterone and its analogs. In particular, induction by TNF, TNFR1, TRADD, TRAF2, NIK and IKK, is modulated by guggulsterone and its analogs. In addition, guggulsterone decreased the expression of genes involved in anti-apoptosis (IAP1, XIAP, Bfl-1/A1, bcl-2, cFLIP, survivin), proliferation (cyclin D1, c-myc) and metastasis (MMP-9, COX2 and VEGF).

The invention provides a novel purpose of triptolide and a triptolide derivative. The triptolide can obviously inhibit the GFP fluorescent protein and P24 antigen rise effect in a phorbol ester activated lymphocyte model. When the concentration of the lymphocyte concentration is higher, the GFP positive cell percentage and the P24 antigen concentration are lower; the negative dosage-effect relationship exists. Even when the concentration of the methylprednisolone is as high as 400 uM, the inhibition effect cannot reach the inhibition effect of the triptolide with the concentration being 0.02 uM; the cell apoptosis proportion obviously exceeds the triptolide with the concentration being 0.02 uM. According to the principle, the triptolide inhibits the G0/G1 period cell proportion rise and S period cell proportion descending due to PMA; the cell period is promoted to be stopped in the unactivated state; the triptolide achieves the effect of inhibiting the lymphocyte cell proliferation and activation through regulating the cell period; meanwhile, the effect of inhibiting the virus replication is also achieved. The triptolide and the triptolide derivative can replace glucocorticoid analogues or can be combined with the glucocorticoid analogues to be used, and are used for treating and/or preventing lung injury diseases.
