in a two-step reaction sequence from corresponding ketones. Some of the title compounds showed (partial) agonist activity at the histamine H3 receptor in vitro and in vivo. Diphenylmethyl carbamate 2 was identified as a new lead structure (ED50 = 5.3 +/- 2.6 mg/kg po, alpha = 1.0). Aromatic substitution in ortho- or para-positions of 2 led to a loss of agonist activity. meta-Substitution was tolerated
在寻找组胺H 3受体的新配体时,合成了新的氨基甲酸二芳基烷基酯(1-19)作为3-(1H-咪唑-4-基)丙醇和-乙醇的衍生物。氨基甲酸酯是通过异氰酸酯通过与双光气反应从相应的胺或从相关的羧酸/二苯基磷酰基叠氮化物和醇组分中生成的。由两步反应,由相应的酮制备受阻胺。在体外和体内,一些标题化合物对组胺H3受体显示(部分)激动剂活性。氨基甲酸二苯甲基酯2被鉴定为新的铅结构(ED50 = 5.3 +/- 2.6 mg / kg po,alpha = 1.0)。2的邻位或对位的芳香取代导致激动剂活性降低。元替代在一定程度上是可以容忍的。这些作用似乎是由取代基的空间特性而非电子特性引起的。对杂环中一个或两个苯基环被杂环交换的研究导致了高活性和选择性的噻吩衍生物18(ED50 3.4 +/- 1.4 mg / kg po,α= 1.0)。组胺H3受体的这些新的(部分)激动剂可以用作研究H3受体的分子方面

in which R1 to R7 have the meanings stated in the claims, act on the Kv1.5 potassium channel and inhibit a potassium current which is referred to as the ultra-rapidly activating delayed rectifier in the atrium of the human heart. They are therefore suitable as novel antiarrhythmic ingredients, such as for the treatment and prophylaxis of atrial arrhythmias, e.g. atrial fibrillation (AF) or atrial flutter.

The present invention is related to the development of therapeutics and prophylactics for the treatment and/or prevention of filovirus infection in humans and other mammals. A new class of small molecules is disclosed that inhibits the interaction of naturally processed (i.e., proteolytically cleaved) filovirus glycoprotein (GPCL) with its host receptor Niemann-Pick C 1 (NPCl) protein and thus block infection of host cells by filoviruses. Also disclosed are methods of using the small molecule inhibitors in the treatment/prevention of filovirus infection.

Azido-functionalized analogs of potently sweet guanidinoacetic acids have been synthesized for use as sweetener receptor photoaffinity labeling reagents. These compounds have been synthesized using readily available starting materials. One of the azido-labeled guanidinoacetic acids has been evaluated in an electrophysiological model in the Rhesus monkey. We found that the photoaffinity-labeling reagent
The catalytic asymmetricarylation of pyridylimines was developed. A range of pyridylimines reacted with arylboronic acids under rhodium catalysis to produce pyridine-incorporating chiral diarylmethylamines in 46% to 99% yield with 90:10 to 99.5:0.5 er, thus providing a method for the preparation of these important chiral pharmacophores.
