毒理性
Alpha-Chaconine在体外对肺腺癌细胞转移具有抑制作用。Alpha-chaconine可以抑制c-Jun N末端激酶(JNK)和Akt的磷酸化,而它并没有影响细胞外信号调节激酶(ERK)和p38的磷酸化。此外,alpha-chaconine显著降低了核因子kappa B(NF-_B)的核水平和NF-_B的结合能力。因此,alpha-chaconine通过减少基质金属蛋白酶-2(MMP-2)和基质金属蛋白酶-9(MMP-9)的活性,涉及磷脂酰肌醇3激酶/Akt/NF-_B(PI3K/Akt/NF-_B)信号通路的抑制,从而抑制A549细胞的转移。Alpha-chaconine对人皮肤、肝脏、前列腺、乳腺和结肠起源的癌细胞生长表现出抗增殖和促凋亡作用。除了在各种癌细胞中的细胞毒性外,R-chaconine在Chang、正常人肝细胞中诱导显著的细胞毒性。(A15417)
Alpha-Chaconine has inhibitory effect on lung adenocarcinoma cell metastasis in vitro. Alpha-chaconine could inhibit phosphorylation of c-Jun N-terminal kinase (JNK) and Akt, whereas it did not affected phosphorylation of extracellular signal regulating kinase (ERK) and p38. In addition, alpha-chaconine significantly decreased the nuclear level of nuclear factor kappa B (NF-_B) and the binding ability of NF-_B. Therefore, alpha-chaconine inhibited A549 cell metastasis by a reduction of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) activities involving suppression of phosphoinositide 3-kinase/Akt/NF-_B (PI3K/Akt/NF-_B) signaling pathway. Alpha-chaconine has exhibited its antiproliferative and apoptotic effects on the growth of cancer cells originating from human skin, liver, prostate, breast, and colon. In addition to the cytotoxicity in various cancer cells, R-chaconine induces significant cytotoxicity in Chang, normal human liver cells. (A15417)
