This invention is directed to novel ether compounds of formula (I) ##STR1## which are of value in medicine in the palliation of haemoglobinopathies, in particular sickle-cell anemia, and also in the palliation of pulmonary dyefunction, protection from the effects of hypoxia and the radio-sensitization of tumours. The invention is also directed to methods for the preparation of the ether compounds, to pharmaceutical formulations containing them, the preparation of such formulations and the use of the compounds in human medicine. Also provided by the invention are intermediates of value in the preparation of the ether compounds, by the methods described, and the preparation of the intermediates.

An iron-catalyzed perezone-type [5 + 2] cycloaddition toward tricyclo[6.3.1.01,6]dodecane scaffolds is presented, furnishing cycloadducts with two new C–C bonds and three to four stereogenic centers generated with typically good yields and excellent diastereoselectivities. Two independent conditions, catalytic FeCl3/PhCO3tBu (0.5 equiv/1 equiv) and stoichiometric FeCl3(2 equiv), have been respectively

Herein we report the synthesis of 21 novel small molecules inspired by metronidazole and Schiffbasecompounds. The compounds were evaluated against Trichomonas vaginalis and cross-screened against other pathogenic protozoans of clinical relevance. Most of these compounds were potent against T. vaginalis, exhibiting IC50 values < 5 µM. Compound 20, the most active compound against T. vaginalis, exhibited
在这里,我们报告了 21 种受甲硝唑和席夫碱化合物启发的新型小分子的合成。这些化合物针对阴道毛滴虫进行了评估,并针对其他具有临床相关性的致病性原生动物进行了交叉筛选。大多数这些化合物对T. vaginalis有效,表现出 IC 50值 < 5 µM。化合物20是对抗阴道毛滴虫最具活性的化合物,其 IC 50值为 3.4 µM。一些化合物还表现出抗恶性疟原虫和布氏锥虫的活性,其中化合物6表现出 IC 50对恶性疟原虫的值为 0.7 µM ,化合物22对布氏结核菌的 IC 50值为 1.4 µM 。化合物22是一种广谱抗原生动物剂,显示出对所有三种正在研究的致病性原生动物的活性。
