制备具有2-甲基,2-乙基,2-异丙基和2-叔丁基的噻吩和硫杂环戊烷衍生物,并通过各种立体选择性方法将其转化为顺式和反式亚硫亚胺和亚砜。顺式sulphilimines通过使用T-BuOCl和TsNH形成-在一个两阶段过程,而环状硫化物通过氯胺-T主要转化成反式- sulphilimines。通过不同的氧化方法获得了富含顺式和反式异构体的亚砜。通过hplc测量非对映异构产物分布,并通过13 C NMR光谱法确定非对映异构体的构型。通过分析13 C NMR和X射线数据确定了亚砜亚胺的优选构象。如图13所示在13 C NMR光谱中,亚硫亚胺和亚砜的构型是相似的。

The present invention provides compounds of formula I:
or a pharmaceutically acceptable salt thereof, wherein R
x
is as defined and described herein, compositions thereof, and methods of using the same.
The invention relates to novel substituted pyrimidine compounds of general formula (I)
in which the chemical groupings, substituents, variables and indices are as defined in the description, and to their use as medicaments, in particular as medicaments for the treatment of conditions and diseases that can be treated by inhibition of the PDE4 enzyme.
Provided is a SLC2A class I transporter inhibitor compound for use in medicine, which compound comprises the following formula:
wherein A and Z may be the same or different and are each independently selected from C, N, O and S; each X may be the same or different and is independently selected from C, N, O and S; R
1
and R
5
may be present or absent and may be the same or different and are each selected from H and a substituted or unsubstituted organic group; Z completes a ring with each X, each ring comprising from 3 to 8 ring atoms including the X, A, and Z, each ring atom being independently selected from C, N, O and S, and each ring atom being unsubstituted or independently substituted with H or a substituted or unsubstituted organic group; and wherein the bonds between all of the atoms in the rings including the X, A, and Z may independently be single bonds or double bonds, provided that when X or a ring atom is O or S the bonds to X are single bonds.
The disclosure relates to cannabinoid derivative compounds, pharmaceutical compositions made thereof, and methods for treating various diseases and disorders including cancer.
本公开涉及大麻素衍生物化合物、由其制成的药物组合物以及治疗包括癌症在内的各种疾病和失调的方法。
