合成了五个系列的吡咯并[3,2- d ]嘧啶,并评估了其与多药耐药相关蛋白1(MRP1,ABCC1)的效力和选择性。该转运蛋白是克服癌症患者多药耐药性的主要靶标。我们在钙黄绿素AM和柔红霉素细胞蓄积试验中,使用选定的阿霉素和过表达MRP1的小细胞肺癌细胞株H69 AR,研究了不同取代的吡咯并嘧啶类化合物。鉴定出具有高效力和选择性的新化合物。位置4的哌嗪残基带有大的苯基烷基侧链,被证明对MRP1抑制是有益的。其被氨基取代导致活性降低。位置5和6的脂族和脂族-芳族变异揭示了具有IC的化合物高纳摩尔范围内有50个值。所有研究的化合物对P-糖蛋白(P-gp,ABCB1)均具有低亲和力。具有小的取代基的吡咯并嘧啶显示出对乳腺癌抗性蛋白(BCRP,ABCG2)的中等抑制作用。

The present invention relates to pyrrole and pyrazole compounds of formula (I) and their pharmaceutically acceptable salts, and further relates to their use in treating schizophrenia, cognitive deficits associated with schizophrenia, Alzheimer's disease, dementia of the Alzheimer's type, mild cognitive impairment, or depression. The compounds act as potentiators on glutamate receptors, in particular AMPA and the GluR family.

Abstract We prepared a series of substituted aminocyanopyrroles and another of aminocynaothiophenes. We describe an efficient new one-step synthetic strategy via the condensation of an alkyl sarcosinate and ethoxymethylenemalononitrile, through a Gewald-like reaction. The UV–visibleabsorption and steady-state and time resolved fluorescence properties of some representative compounds, as well as their

N-Aryl and alkylaminomethylene cyanacetic acid derivatives 1 react with alpha-halogencarbonyl compounds 2 in the presence of potassium carbonate/sodium ethoxide to yield the substituted 3-amino-pyrroles 6. Using the same principle of cyclization pyrrole derivatives 6 can also be obtained by reaction of beta-chloro- and beta-alkoxymethylenemalononitriles 4 with beta-aminocarbonyl compounds 5. From the malononitrile derivatives 1 containing the methylthio group in the beta-position, and alpha-halogen ketones 7, the 2-dicyanomethylene oxazolines 8 arise which undergo alkoholysis by treatment with sodium alkoxide to form the 3-amino-5-alkoxy-pyrrole derivatives 9.
