N6-[(Hetero)aryl/(cyclo)alkyl-carbamoyl-methoxy-phenyl]-(2-chloro)-5′-N-ethylcarboxamido-adenosines: The first example of adenosine-related structures with potent agonist activity at the human A2B adenosine receptor
摘要:
A new series of N-6-[(hetero)aryl/(cyclo)alkyl-carbamoyl-methoxy-phenyl]-(2-chloro)-5'-N-ethylcarboxamido-adenosines (24-43) has been synthesised and tested in binding assays at hA(1), hA(2A) and hA(3) adenosine receptors, and in a functional assay at the hA(2B) subtype. The examined compounds displayed high potency in activating A(2B) receptors with good selectivity versus A(2A) subtypes. The introduction of an unsubstituted 4-[(phenylcarbamoyl)-methoxyl-phenyI chain at the N-6 position of 5'-N-ethylcarboxamido -adenosine led us to the recognition of compound 24 as a full agonist displaying the highest efficacy of the series (EC50 hA(2B) = 7.3 nM). These compounds represent the first report about adenosine-related structures capable of activating hA2B subtype in the low nanomolar range. (c) 2007 Elsevier Ltd. All rights reserved.

with mild anticanceractivity. In this paper we report the synthesis of new chrysin derivatives alkylated with N-phenylchloroacetamides in position 7. A novel method was developed for the preparation of 7-aminochrysin derivatives via the Smiles rearrangement, resulting in diphenylamine-type compounds. In silico studies of the Smiles rearrangement were performed. We also present the in vitro antiproliferative

of iodinated quinazolinones carrying benzenesulfonamide moiety as carbonicanhydrase (CA, EC 4.2.1.1) inhibitors. The target compounds showed promising inhibitory activity against the four examined human (h) CA isoforms; I, II, IX and XII. Compounds 4-18 displayed variable inhibition constants, ranging as follows: 7.6–782.8 nM for hCA I, 34.4–412.1 nM for hCA II, 29.1–2225.3 nM for hCA IX and 8.8–429
在本工作中,我们报告了一组设计和合成的碘化喹唑啉酮类化合物,它们带有苯磺酰胺部分作为碳酸酐酶(CA,EC 4.2.1.1)抑制剂。目标化合物对四种被检测的人(h)CA同工型均显示出有希望的抑制活性。I,II,IX和XII。化合物4-18显示出可变的抑制常数,范围如下:hCA I为7.6–782.8 nM,hCA II为34.4–412.1 nM,hCA IX为29.1–2225.3 nM,hCA XII为8.8–429.4 nM。化合物9是最有效的抗肿瘤特异性CA IX / CA XII(K I = 29.1和8.8 nM)的化合物,有可能在体外评估其对HepG-2,HCT-116和MCF-7癌细胞的细胞毒性和选择性线。化合物9对肿瘤细胞系具有显着的细胞毒性(分别为IC 50 = 1.78、1.94和3.07μM),对WI38正常细胞系的毒性相对较低。在接受单剂量的8 Gyγ射线照

effective and safe anticancer drug, we synthesized a novel series of quinazoline containing biologically active substituted-sulfonamide moiety at 3- position 4a–n. The structure of the newly prepared compounds was proved by microanalysis, IR, 1H-NMR, 13C-NMR and mass spectral data. All the synthesized compounds were evaluated for their in vitro cytotoxic activity in numerous cancercelllines including A549
