The present invention relates to novel retinoid-related orphan receptor gamma (RORγ) modulators and their use in the treatment of diseases mediated by RORy.
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

Of 38 hosts, most of them new, designed on the ‘wheel-and-axle’ model, 24 formed clathratecomplexes with small molecules; 95 new host/guest combinations are described (Table 6). Selectivitystudies (Table 7) show, in some instances, substantial discrimination between guests with similar structures.
stereodivergent synthesis of styrylglycine nitriles has also been accomplished by using racemic and enantioenriched 2‐methylbenzhydrylamine. Thus, accompanied with a small rearrangement of the common substrate from achiral toward chiral, the present reactions induce an enhancement of chirality, and expands the concept of stereoselective synthesis to increase the opportunity to access highly enantioenriched compounds
