  2,3-Dihydro-dithiin and -dithiepine-1,1,4,4-tetroxides: small molecule non-peptide antagonists of the human galanin hGAL-1 receptor

  摘要：

  The neuropeptide galanin modulates several physiological functions such as cognition, learning, feeding behavior, and depression, probably via the galanin 1 receptor(GAL-R1). Using an HTS assay based on I-125-human galanin binding to the human galanin-l receptor (hGAL-R1), we discovered a series of 1,4-dithiin and dithiipine-1,1,4,4-tetroxides that exhibited binding affinity IC50's to hGAL-R1 ranging from 190 to 2700 nM. Two of the dithiepin analogues, 7 and 23, behaved pharmacologically as hGAL-R1 antagonists in secondary assays involving adenylate cyclase activity and GTP binding to G-proteins. Analogues 7 and 23 were also active in functional assays involving galanin, reversing the inhibitory effect of galanin on acetylcholine (ACh) release in rat brain hippocampal slices and electrically-stimulated guinea pig ileum twitch.

  and ketones by β‐amino alcohol‐derived Schiff base ligands with two stereogenic centers was investigated. Using aqueous hydrogen peroxide as the oxidant and the Schiff base 3b as a chiral ligand, a variety of 1,3‐dithianes derived from aldehydes were easily converted into the corresponding mono‐sulfoxides in good yields (81–88%) with excellent enantioselectivities (up to 99% ee). Additionally, 99% ee

  研究了由β-氨基醇衍生的席夫碱配体与两个立体生成中心的不对称钒催化醛和酮催化的1,3-二硫杂环丁烷的氧化。使用过氧化氢水溶液作为氧化剂和席夫碱3b作为手性配体，可以将各种衍生自醛的1,3-二硫杂环丁烷以良好的对映选择性（81-88％）轻松转化为相应的单亚砜（高达99％ee）。此外，ee为99％可以通过对映体钒催化从酮中衍生的1,3-二硫杂环丁烷进行氧化。当在醛衍生的1,3-二噻吩类化合物的氧化过程中使用较高比例的过氧化氢时，而在酮衍生的1,3-二噻吩类化合物中，则没有发现动力学分解。

  A facile method for deblocking of dithianes is described. Diacetoxyiodobenzene was used as a cheaper variant of bis(trifluoroacetoxy)iodobenzene for the regeneration of carbonyl compounds from dithianes.
