  Synthesis and evaluation of quinazoline derivatives as phosphodiesterase 7 inhibitors

  摘要：

  The latest scientific findings concerning PDE7 and PDE4 inhibition suggest that selective small-molecule inhibitors of both enzymes could provide a novel approach to treat a variety of immunological diseases. In this context, we describe a new series of quinazoline derivatives from quinazolin-4-thiones which include a substituted biphenyl fragment. Some of these compounds show inhibitory potencies at sub-micromolar levels against the catalytic domain of PDE7. (C) 2013 Elsevier Ltd. All rights reserved.

  Conversion of 2-Thioxo-2,3-dihydroquinazolin-4(1H)-ones to N(3)-Unsubstituted 2-(Het)Arylquinazolin-4(3H)-ones by Copper-Mediated Pd-Catalysed Cross-Coupling Reactions

  摘要：

  With the purpose of searching for new heterocyclic building blocks, a new method to access N(3)-unsubstituted 2-(het)arylquinazolin-4(3H)-ones from 2-thioxo-2,3-dihydroquinazolin-4(1H)-one derivatives was developed. The synthetic protocol was based on the copper-mediated palladium-catalysed cross-coupling reactions of 2-thioxo-2,3-dihydroquinazolin-4(1H)-ones with (het)arylstannanes or their S-benzylated derivatives with (het)arylboronic acids, using CuBr center dot Me2S and CuMeSal as promoters, respectively. A similar transformation was applied for the preparation of 2-aryl[ 1]benzothieno[3,2-d]pyrimidin-4(3H)-ones.

  The sulfonylation of quinazolin-4(3H)-ones and related tetrahydrobenzothieno[2,3-d]pyrimidin-4(3H)-ones with mesyl, tosyl, and p-cyanobenzenesulfonyl chloride was studied. A hydrogen substituent at 2-position directed the sulfonyl group to the N-3 position, while alkylsulfanyl or amino substituents led to sulfonylation of the carbonyl oxygen. The latter effect was attributed to steric influence and

  substituents in positions 2 and 4 of the previously synthesized but yet undisclosed 5-cyano-4-(methylthio)-2-arylpyrimidin-6-ones 4, ring closure, and further optimization led to the identification of the potent antitubercular 2-thio-substituted quinazolinone 26. Structure–activity relationship (SAR) studies indicated a crucial role for both meta-nitro substituents for antitubercular activity, while the introduction

  Reaction of 2-thioquinazolinone (1) with various alkylating agents like dimethyl sulphate, diethyl sulphate and benzyl chloride in the presence of K2CO3 as a mild base, by a simple physical grinding, microwave irradiation and PEG-600 under solvent-free conditions for 10-15 min at room temperature, followed by processing, gave respectively 2-methylsulfanyl-3H-quinazolin- 4-one (2a, i.e., R = CH3), 2-ethylsulfanyl-3H-quinazolin-4-one (2b, i.e., R = C2H5) and 2-benzyl sulfanyl-3H-quinazolin-4-one (2c, i.e., R = PhCH2Cl). It appears from this study that green syntheses such as solid phase synthesis (physical grinding) and microwave irradiation gives better yields, quality and in less reaction time the products over conventional methods involving green solvents like ethanol, PEG-600 etc. The entire sequences of reactions have been carried out using eco-friendly solvents and green conditions.

  In the present study, a series of fourteen 2-mercapto-4(3H)-quinazolinone derivatives was synthesised and evaluated as potential inhibitors of the human monoamine oxidase (MAO) enzymes. Quinazolinone is the oxidised form of quinazoline, and although this class has not yet been extensively explored as MAO inhibitors, it has been shown to possess a wide variety of biological activities. Among the quinazolinone

  在本研究中，合成了一系列十四个2-巯基-4（3 H）-喹唑啉酮衍生物，并将其评估为人单胺氧化酶（MAO）酶的潜在抑制剂。喹唑啉酮是喹唑啉的氧化形式，尽管该类作为MAO抑制剂尚未得到广泛研究，但已显示其具有多种生物学活性。在研究的喹唑啉酮衍生物中，有7种化合物（IC 50  <1 µM）被证明是有效的和特异性的MAO-B抑制剂，其中最有效的抑制剂是2-[（（3-碘苄基）硫代]喹唑啉-4（3 H）-一种显示的IC 50值为0.142μM。进一步的研究表明，该抑制剂是具有K的MAO-B的可逆和竞争性抑制剂。i值为0.068 µM。测试化合物均不是MAO-A抑制剂。对MAO-B抑制的构效关系（SAR）的分析表明，在喹唑啉酮的C2位上被在间位上带有Cl，Br或I的苄硫基部分取代，产生了该系列中最有效的抑制剂。相反，用未取代的苄硫基部分（IC 50  ＝3.03μM）取代导致对MAO-B的抑制活性明显
