Combinatorial synthesis of substituted 3-(2-indolyl)piperidines and 2-phenyl indoles as inhibitors of ZipA–FtsZ interaction
摘要:
The ZipA-FtsZ protein-protein interaction is a potential target for antibacterial therapy. The design and parallel synthesis of a combinatorial library of small molecules, which target the FtsZ binding area on ZipA are described. Compounds were demonstrated to bind to the FtsZ binding domain of ZipA by HSQC NMR and to inhibit cell division in a cell elongation assay. (C) 2004 Elsevier Ltd. All rights reserved.

Abstract Oximes, hydrazones, and semicarbazones can be converted to their corresponding carbonyl compounds in good to high yields by a combination of silica chloride and wet SiO2.
of a series of novel pyrazole–indanone hybrid analogs. The target compounds have been synthesized by the Claisen–Schmidt condensation of different 1,3-diphenyl-1H-pyrazole-4-carbaldehydes with 2,3-dihydro-1H-inden-1-one in the presence of potassium hydroxide. The compounds were characterized by IR, 1H and 13C NMR, and mass spectra and were found to exhibit potent antimicrobialactivity in vitro.

months. In this study, various pyrazolic chalcone analogous compounds were synthesized and evaluated as potential chemotherapeutic agents for the treatment of hepatocellular carcinoma (HCC). Modifying the central pyrazole ring at the C(3)-position with different heteroaryl rings and substituting the C(4)-position of pyrazole with differently substitutedchalcone moiety produced fouthy two variant compounds
The design, synthesis, structure–activity relationship, and biological activity of 2,4‐thiazolidinedione derivatives as peroxisome proliferator‐activated receptor‐γ (PPAR‐γ) modulators for antidiabetic activity are reported. Fifteen 2,4‐thiazolidinedione derivatives clubbed with pyrazole moiety were docked into the ligand binding domain of PPAR‐γ by the Glide XP module of Schrodinger. Eight derivatives
2,4-噻唑烷二酮衍生物作为过氧化物酶体增殖物激活受体-γ(PPAR-γ)调节剂的设计、合成、结构-活性关系和生物活性已被报道。通过薛定谔的 Glide XP 模块,15 种带有吡唑部分的 2,4-噻唑烷二酮衍生物对接在 PPAR-γ 的配体结合域中。与标准药物罗格列酮(Glide XP 评分 = -9.165)相比,Glide XP 评分 > -8 的八种衍生物(5a、5b、5d、5f、5i、5l、5n、5o)显示出与氨基的几乎相似的相互作用分子对接研究中的酸,如 HIS 449、TYR 473、TYR 327、HIS 323 和 SER 289。在链脲佐菌素诱导的糖尿病大鼠模型中,进一步筛选了这八种衍生物的 PPAR-γ 反式激活和体内血糖降低活性。与参考药物罗格列酮和吡格列酮相比,化合物 5o、5n、5a、5i 和 5b 的 PPAR-γ 反式激活分别为 52.06、51.30、48
Design, synthesis and biological evaluation of novel 1,3-diarylpyrazoles as cyclooxygenase inhibitors, antiplatelet and anticancer agents
With the aim of achieving new compounds possessing both anti-inflammatory and antiplatelet activities, we synthesized (E)-3-[3-(pyridin-3/4-yl)-1-(phenyl/sulfonylmethylphenyl)-1H-pyrazol-4-yl]acrylamides, and evaluated their COX-1 and COX-2 inhibitory and antiplatelet activities. Since COX-2 inhibitory and antiplatelet compounds have anticancer potential, we also screened their antiproliferative effects
