In vitro anti-inflammatory potential and QSAR analysis of oxazolo/thiazolo pyrimidine derivatives
摘要:
Twenty-six different benzylidene oxazolo/thiazolo (3,2-a)-pyrimidine-6-carboxamide derivatives were synthesized and evaluated for their anti-inflammatory potential by protein denaturation method. The structures of title compounds were characterized by IR and NMR spectral data. The SAR studies reveal that compounds containing electron withdrawing polar group at para position of 5-phenyl ring and electron withdrawing non-polar group at para position of 2-benzylidene moiety of thiazolo pyrimidine nucleus have better anti-inflammatory potential. The 2D-QSAR studies were performed on VLife MDS software which reveals that anti-inflammatory potential of benzylidene-3-oxo-5H-oxazolo/thiazolo (3,2-a)-pyrimidine-6-carboxamides is dependent on estate contribution, alignment independent, individual and path count descriptors.
A class of compounds with a common thiazolo[3,2‐a]pyrimidinone motif has been developed as generalinhibitors of Bcl‐2 familyproteins. 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。

Efficient Synthesis of 5-Carboxanilide-Dihydropyrimidinones Using Cobalt(II) Nitrate Hexahydrate
5‐Carboxanilide‐dihydropyrimidinone derivatives were synthesized in good yield in a three‐component and efficient process by the condensation reaction of acetoacetanilide, aldehyde and urea/thiourea in the presence of cobalt(II) nitrate hexahydrate as catalyst in ethanol at ambient condition.
