First Metal-Containing Histamine H3 Receptor Ligands
摘要:
Iron-containing ligands targeting the human histamine H-3 receptor (hH(3)R) were prepared. The compounds contain ferrocene sandwich complexes coupled via different linkers to a basic hH(3)R antagonist/inverse agonist pharmacophore. In a click chemistry approach, a triazole was successfully inserted as a new linking element. Two ferrocenylmethylamines and a ferrocenyltriazole were the most affine hH(3)R ligands within this series, showing receptor binding in the nano- and subnanomolar concentration range.

of multitarget‐directed drugs (MTDs). Novel indole derivatives with inhibitory activity towards acetyl/butyrylcholinesterases and monoamine oxidases A/B as well as the histamineH3receptor (H3R) were obtained by optimization of the neuroprotectant ASS234 by incorporating generally accepted H3R pharmacophore motifs. These small‐molecule hits demonstrated balanced activities at the targets, mostly in
复杂的神经退行性疾病的治疗需要开发多靶标定向药物(MTD)。通过掺入普遍接受的H3R药效基团来优化神经保护剂ASS234,可获得对乙酰基/丁酰胆碱酯酶和单胺氧化酶A / B以及组胺H 3受体(H3R)具有抑制活性的新型吲哚衍生物。这些小分子命中物显示了在靶标上的平衡活性,主要是在纳摩尔浓度范围内。其他体外研究显示抗氧化神经保护作用以及穿透血脑屏障的能力。有了这种有前途的体外研究,辅助剂(1 mg kg -1 ip)可以显着改善脂多糖引起的认知功能障碍。

A novel class of indole ligands for estrogen receptor alpha have been discovered which exhibit potent affinity and high selectivity. Substitution of the bazedoxifene skeleton to the linker present in the HTS lead 1a provided 22b which was found to be 130-fold alpha-selective and acted as an antagonist of estradiol activity in uterine tissue and MCF-7 cancer cells.
