    摘要:
    乙酰胆碱酯酶(AChE)是主要的药物靶标,其抑制剂已在对症治疗阿尔茨海默氏病(AD)中显示出功能。在这项研究中,设计了一系列新颖的AChE抑制剂,并使用20种已知化合物的训练集进行了二维定量结构-活性关系(QSAR)研究,评估了其抑制活性,这些化合物先前已确定了IC 50值。QSAR模型是基于七个唯一描述符来计算的。模型验证是通过预测来确定IC 50个值的测试组20种独立化合物与测量IC 50值。进行了相关分析,比较了测得的IC 50的统计数据具有预测值的值。这些决定选择性的描述符通过主成分分析(PCA)进行了图形化解释。还根据训练集的活动创建了3D药效团模型。此外,还确定了吸收,分布,代谢和排泄(ADME)指标,以评估其药代动力学特性。最后,这些新型分子与AChE结合域的分子对接表明,与已知的标准药物多奈哌齐相比,三个分子(6c,7c和7h)应具有显着更高的亲和力和溶剂化能。2 H-噻唑并[3

    A class of compounds with a common thiazolo[3,2‐a]pyrimidinone motif has been developed as general inhibitors of Bcl‐2 family proteins. The lead compound was originally identified in a random screening of a small compound library using a fluorescence polarization‐based competitive binding assay. Its binding to the Bcl‐xL protein was further confirmed by 15N‐HSQC NMR experiments. Structural modifications
    一类具有常见的噻唑并[3,2- a ]嘧啶酮基序的化合物已被开发为Bcl-2家族蛋白的一般抑制剂。最初使用基于荧光偏振的竞争结合测定法对小型化合物库进行随机筛选来鉴定先导化合物。15 N-HSQC NMR实验进一步证实了其与Bcl-x L蛋白的结合。分子模型研究的结果指导了对先导化合物的结构修饰。与先导化合物相比,在获得的42种化合物中,许多化合物与Bcl-2家族蛋白的结合亲和力大大提高。最有效的化合物BCL‐LZH‐ 40抑制BH3肽与Bcl‐x L的结合和Bcl-2和Mcl-1的与抑制常数(ķ我)的17,534和200N的中号,分别。

    The compounds, 7-methyl-3,5-diphenyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylic acid ethyl ester (1), 3-amino-2-cyano-7-methyl-5-phenyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylic acid methyl ester (2), 2-dimethylaminomethylene-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidine-6-carboxylic acid ethyl ester (3), 2-(3-cyano-benzylidene)-5-(4-hydroxy-phenyl)-7-methyl-3-oxo-2,3-dihydro-5H-thiazolo[3,2-a]pyrimidine-6-carboxylic acid methyl ester; with N,N-dimethyl-formamide (4) and 3-ethoxycarbonylmethyl-5-(4-hydroxy-3-methoxy-phenyl)-7-methyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxylic acid methyl ester (5) have been synthesized and their structures evaluated crystallographically. Compound 1 crystallizes in the space group Pı̄ with Z=8, with four molecules in the asymmetric unit. Compound 2 also crystallizes in the space group Pı̄ with Z=4 wherein asymmetric unit accommodates two molecules. Compound 3 belongs to P21/c with Z=4, compound 4 crystallizes in Pbc2 1 with Z=4 and compound 5 belongs to Pı̄ with Z=2. In all the above compounds, the aryl ring positioned at C5 of thiazolopyrimidine ring is almost perpendicular. In the case of compounds with substituted phenyl ring, aryl group-up conformation predominates. However, for compounds with unsubstituted phenyl ring, aryl group-down conformation is adopted. By varying the substituents at positions C2, C3, C6 and on the aryl at C5 in the main molecular scaffold of (1-5), we have observed significant differences in the intermolecular interaction patterns. The packing features of the compounds are controlled by C-H…O, C-H…N, N-H…N O-H…N, C-H…π and π…π weak interactions.
