METHODS The inhibition effect of IC to Suso cells in vivo was evaluated by the tumor weight of the mice bearing tumorand the tumor inhibition rate. The effects on spleen and thymus were also observed. Long term carcinogenesis model was induced byN-methyl-N-nitro-N-nitrosoguanidine( MNNG). The in vitro anticancer effect was studied by MTT assay. RESULTSobtained that HeLa cells were obviously inhibited by the influence of IC in vitro. And there was positive correlation between thetory effect and IC concentration. Furthermore, the IC also had the anticancer activity to the Suso cells of the mice bearing tumor. Thedeclining of spleen and thymus index indicated that IC had the effect of immunosuppressant. IC can reduce the precancerous affectionsand cancer ratio in long term carcinogenesis experiments. coNclusion IC has some effect on inhibition of tumor.Key words: Indole-3-carbinol; Antitumor; GlucosinolateCLC number: R96Document code: AArticle n:1006-0103(2008)01-004硫代葡萄糖苷(硫苷)是一類廣泛存在于十字素(深圳華藥南方制藥有限公司,批號(hào):NO60502);花科植物根、莖、果實(shí)中的糖苷類混合物,特別是蕓甲硝基亞硝基胍(MNNG,日本東京化成試劑);小鼠苔屬 brassica植物,包括各種卷心菜、椰菜、花椰菜肉瘤細(xì)胞株(S3,華中科技大學(xué)同濟(jì)醫(yī)學(xué)院藥學(xué)和布魯塞爾苗芽。至今已發(fā)現(xiàn)120多種硫苷,在十院);人宮頸癌HeIa細(xì)胞(華中科技大學(xué)光電國(guó)家字花科植物中已鑒定出27種。根據(jù)側(cè)鏈基團(tuán)的重點(diǎn)實(shí)驗(yàn)室傳代保株)。SF級(jí)昆明種小鼠[湖北省氨基酸來(lái)源不同,可將硫苷分為脂肪族、芳香族、吲實(shí)驗(yàn)研究中心,許可證號(hào):SCXK(鄂)2003-0007哚族硫苷。硫苷本身是一種較為穩(wěn)定的化合物,但♀♂兼用,體重18-22g。在芥子酶或胃腸道中的細(xì)菌酶的催化作用下,會(huì)發(fā)1.2方法與結(jié)果生降解并生成多種降解產(chǎn)物2。文獻(xiàn)報(bào)道吲哚1.2.1IC對(duì)同種移植性腫瘤的作用取接種于昆族硫苷中的3-吲哚甲基硫苷的降解產(chǎn)物3-吲哚明小鼠約7-10d的S1m腫瘤,無(wú)菌條件操作,剔除甲醇(C)可預(yù)防癌癥的發(fā)生(圖1)。作者研究了包膜和壞死部分,選取完好的瘤塊,置玻璃勻漿器IC的體內(nèi)體外的抗腫瘤作用以探討其用于治療內(nèi)加入適量生理鹽水配制成瘤細(xì)胞懸液細(xì)胞數(shù)癌癥的可能性。為1×107-2×10·ml-,接種于同種異體小鼠前肢/ s-b-D glucosecH。-c腋皮下,每只小鼠注射0.2ml。之后動(dòng)物隨機(jī)分組s一 B-D glucose分籠飼養(yǎng)。制成實(shí)體型荷瘤模型。治療組謳供試N-OSO3Indole-3-ylmethyl glucosinolate液,qd;陰性對(duì)照組用水;陽(yáng)性對(duì)照組用環(huán)磷酰胺(CⅨX),隔日p給藥1次。S1荷瘤小鼠連續(xù)給藥10d,停藥次日,脫頸處死動(dòng)物,剝?nèi)×鲶w組織、脾、胸腺稱重,計(jì)算腫瘤系數(shù)、抑瘤率及臟器系數(shù)。采用組間t檢驗(yàn)及方差分析,應(yīng)用SPSS12.0統(tǒng)圖1化合物的結(jié)構(gòu)計(jì)軟件包進(jìn)行統(tǒng)計(jì)學(xué)分析。對(duì)S1颱荷瘤小鼠的抑瘤Fig 1 Structures of compounds作用和脾臟、胸腺重量的影響見(jiàn)表1實(shí)驗(yàn)結(jié)果顯示,IC對(duì)♂小鼠S1有顯著抑制作1實(shí)驗(yàn)部分用,大小劑量的抑瘤率分別為36.92%34.73%;陽(yáng)1.1儀器、試藥與動(dòng)物性藥物環(huán)磷酰胺可明顯抑制腫瘤的生長(zhǎng),抑瘤率為二氧化碳培養(yǎng)箱(美國(guó) NuAire);倒置顯微鏡51.5%。環(huán)磷酰胺具有免疫抑制作用,與陰性對(duì)照(cOIC);酶標(biāo)儀(芬蘭 Wallac)。3-吲哚甲醇(LC,組相比,可使脾臟和胸腺系數(shù)降低,而大小劑量的Sigma公司,純度99%,批號(hào):122190050);環(huán)磷酰胺C也能使臟器系數(shù)降低,其中大劑量C對(duì)脾臟的江蘇恒瑞醫(yī)藥股份有限公司,批號(hào):06090521);溴抑制作用稍強(qiáng)于環(huán)磷酰胺。由于♀♂個(gè)體差異,在化二甲噻唑二苯四氮唑(MT, Amresco公司分裝);♀荷瘤中國(guó)煤化工相差較大,大劑DMEM培養(yǎng)基(Gb公司);新生牛血清(杭州四季量的抑♀小鼠免疫器青生物工程材料有限公司,批號(hào):00201);二甲基亞官具有CNMH腺也有極顯著砜(DMSO,天津市大茂化學(xué)試劑廠);青霉素鈉(華的抑制作用。北制藥股份有限公司,批號(hào):S0509301);硫酸鏈霉L.22對(duì)化學(xué)物質(zhì)誘發(fā)性動(dòng)物腫瘤的作用取華西藥學(xué)雜志第23卷豪1IC對(duì)小鼠S1m腫瘤和免疫器官的影響(mgkg1,舞=8Table 1 Influence of IC on 8Sm sarcom mouse and immune organs( mg.kg", m=)aSIa sarcom mouse♀S1 RAnCOmGroupsmg.kg-1 Tc/) Ir/% Oe spleenControl14.4±3.0-12.481±6.821.954±0.4819.3±4.712.173±0.933.568±0.7294±2.6·34.739.861±2.221.881±1.0916.0±4.317.229.958±2.443.160±0.12928.403±1.531.897±04±4.8·41.1311.852±2.06L.841±0.56Compared with control group: P<0. 05,.
