1.One goal in our studies is the synthesis of new {5-deaza-and8-deazapteridines} as folate antagonists. 2.b-dicarbonyl derivatives or a,b-unsaturated aldehydes, were cyclocondensated with different {1,3-bisnucleophiles} , e.g., cyanacetamide(7)or pyrimidine-2,4,6-triamine(14). 3.12was than treated with dimethylformamideand phosphoroxychloride under mild conditions and furtherwithN,N-dimethylammoniumperchlorate to yield the {trime-thinium perchlorate} 13, representing a reactive derivative ofmalondialdehyde[19]. 4.Recently an alternative preparation of Nor-PTX(3)has been published by condensation14and { bromomalondialdehyde} ,followed by protection of amino groups and Pd-mediated coupling with 2,5-dimethoxybenzyl zinc chloride and final deprotection of the pivaloylated aminogroups[16](Fig. 3) 5. Treatment with dimethylformamide, phos-phoroxychloride and crystallisation with {N,N-dimethyl am-monium per chlorate} gave { trimethinium }salt24 6.{Before methotrexate can act as an antitumor agent, an active transport mechanisms into the cell and polyglutamation by the enzyme folypoly-glutamate synthase is necessary.} 7.{Pneumocystis cariniiandToxoplasma gondii} 意思大括號的詞或句,每個編號都是一句話,為了更清楚的看到要翻譯的詞,所以斷開。 感謝 |

1、5-deaza-and 8-deazapteridines:5 - 脫氮和8 - 脫氮蝶啶 2、1,3-bisnucleophiles:1,3- 雙核試劑 3、trime-thinium perchlorate:三亞甲高氯酸鹽 4、bromomalondialdehyde:溴丙二醛 5、N,N-dimethyl ammonium:N,N- 二甲基銨; per chlorate:每(分子)氯酸鹽(多為氯化鈉);trimethinium:三亞甲 6、Before methotrexate can act as an antitumor agent, an active transport mechanisms into the cell and polyglutamation by the enzyme folypoly-glutamate synthase is necessary:在可以作為抗腫瘤劑之前,氨甲蝶呤必需通過一種主動運(yùn)輸機(jī)制進(jìn)入細(xì)胞內(nèi),并在葉酰聚谷氨酸合酶作用生成聚谷氨酸。 有源傳輸機(jī)制成通過酶folypolyglutamate合酶的細(xì)胞和polyglutamation是必要 7、Pneumocystis carinii and Toxoplasma gondii:卡氏肺囊蟲和弓形蟲 |
