  摘要：

  Optimisation of a screening hit incorporating both TRPV1 activity and solubility was conducted. Substitution of the isoxazole-3-carboxamide with the bespoke 1S, 3R-3-aminocyclohexanol motif afforded the requisite balance of potency and solubility. Compounds 32 and 40 were found to have antihyperalgesic effects in the rat CFA Hg assay and induce a mechanism based hyperthermia. (C) 2010 Elsevier Ltd. All rights reserved.

  结合有芳基哌嗪部分作为抗癌剂的新型异恶唑衍生物的合成和细胞生物活性。

  摘要：

  在我们努力开发有效的抗癌疗法的过程中，合成了一系列新的异恶唑-哌嗪杂种，并评估了它们对人肝（Huh7和Mahlavu）和乳腺癌（MCF-7）癌细胞系的细胞毒活性。在系列中，化合物5l-o在所有细胞系中显示出最强的细胞毒性，IC50值在0.3-3.7μM的范围内。为了探究观察到的活性的基本机制，对肝癌细胞中5m和5o进行了进一步的生物学研究。我们已经证明5m和5o在足够的PTEN Huh7和PTEN不足的Mahlavu人肝癌细胞中诱导氧化应激，导致细胞凋亡和细胞周期停滞在不同阶段。

• Discovery of 3-aryl-5-acylpiperazinyl-pyrazoles as antagonists to the NK3 receptor

  A series of 3-aryl-5-acylpiperazinyl-pyrazoles (e.g., 3a-b) initially identified through a high-throughput screening campaign using the aequorin Ca2+ bioluminescence assay as novel, potent small molecule antagonists of the G protein-coupled human tachykinin NK3 receptor (hNK3-R) is described. Preliminary profiling revealed poor plasma and metabolic stability for these structures in rodents. Further optimization efforts resulted in analogs with improved potency, stability, and pharmacokinetic properties as well as good brain permeability, for example, compounds 26 and 42. Unexpected cytotoxicity was observed in such N-Me pyrazole structures as compounds 41-42. (C) 2011 Elsevier Ltd. All rights reserved.

  In our endeavour towards the development of effective anticancer therapeutics, a novel series of isoxazole-piperazine hybrids were synthesized and evaluated for their cytotoxic activities against human liver (Huh7 and Mahlavu) and breast (MCF-7) cancer cell lines. Within series, compounds 5l-o showed the most potent cytotoxicity on all cell lines with IC50 values in the range of 0.3-3.7 μM. To explore
