An octahydro-cyclopenta[c]pyrrole series of inhibitors of the type 1 glycine transporter
摘要:
We describe a novel series of inhibitors of the type 1 glycine transporter (GlyT1) as an approach to relieving the glutamatergic deficit that is thought to underlie schizophrenia. Synthesis and SAR follow-up of a series of octahydro-cyclopenta[c]pyrrole derivatives afforded potent in vitro inhibition of GlyT1 as well as in vivo activity in elevating CSF glycine. We also found that a 3-O(c-pentyl), 4-F substituent may serve as a surrogate for the widely used 3-trifluoromethoxy group, suggesting its application as an isostere for future medicinal chemistry studies.

Hydroformylation of fluorinatedalkenes is an efficient method for the preparation of fluorinated functionalized building blocks for the synthesis of biologically active target structures. In this article we summarize known hydroformylation reactions of fluorinatedolefins and we add new results from our research groups. Particular attention is paid to the remarkable influence of organofluorine substituents
The inhibition of PTPN2 and PTPN1 has emerged as an attractive approach to sensitize T cell anti-tumor immunity. Two small molecule inhibitors have been entered the clinic. Here we report the design and development of compound , a novel small molecule PTPN2/N1 inhibitor demonstrating nanomolar inhibitory potency, good oral bioavailability, and robust antitumor efficacy.
