This study will examine the effectiveness of 28 days of triple combination therapy including SCY-635 with peginterferon alfa 2a and ribavirin in reducing serum HCV RNA levels. An additional 20 weeks of treatment with the currently approved standard of care will be offered to all participants. The Week 24 visit will be the last on-study visit. After the Week 24 visit, all subjects with undetectable HCV RNA will be given the option to continue treatment with standard of care for an additional 24 weeks (out to Week 48) under the care of their Principal Investigator.

AbstractINTRODUCTIONBlood phosphorylated tau at threonine 217 (tau‐PT217) is a newly established biomarker for Alzheimer's disease and postoperative delirium in patients. However, the mechanisms and consequences of acute changes in blood tau‐PT217 remain largely unknown.METHODSWe investigated the effects of anesthesia/surgery on blood tau‐PT217 in aged mice, and evaluated the associated changes in B cell populations, neuronal excitability in anterior cingulate cortex, and delirium‐like behavior using positron emission tomography imaging, nanoneedle technology, flow cytometry, electrophysiology, and behavioral tests.RESULTSAnesthesia/surgery induced acute increases in blood tau‐PT217 via enhanced generation in the lungs and release from B cells. Tau‐PT217 might cross the blood–brain barrier, increasing neuronal excitability and inducing delirium‐like behavior. B cell transfer and WS635, a mitochondrial function enhancer, mitigated the anesthesia/surgery‐induced changes.DISCUSSIONAcute increases in blood tau‐PT217 may contribute to brain dysfunction and postoperative delirium. Targeting B cells or mitochondrial function may have therapeutic potential for preventing or treating these conditions.

A multifunctional cross-validation high-throughput screening protocol enabling the discovery of new SHP2 inhibitors

Q1 · CHEMISTRY

Author: Yu, Bin ; Wu, Yahong ; Liu, Hong-Min ; Zhao, Min ; Song, Yihui

The protein tyrosine phosphatase Src homology phosphotyrosyl phosphatase 2 (SHP2) is implicated in various cancers, and targeting SHP2 has become a promising therapeutic approach. We herein described a robust cross-validation high-throughput screening protocol that combined the fluorescence-based enzyme assay and the conformation-dependent thermal shift assay for the discovery of SHP2 inhibitors. The established method can effectively exclude the false positive SHP2 inhibitors with fluorescence interference and was also successfully employed to identify new protein tyrosine phosphatase domain of SHP2 (SHP2-PTP) and allosteric inhibitors. Of note, this protocol showed potential for identifying SHP2 inhibitors against cancer-associated SHP2 mutation SHP2-E76A. After initial screening of our in-house compound library (∼2300 compounds), we identified 4 new SHP2-PTP inhibitors (0.17% hit rate) and 28 novel allosteric SHP2 inhibitors (1.22% hit rate), of which SYK-85 and WS-635 effectively inhibited SHP2-PTP (SYK-85: IC₅₀ = 0.32 μmol/L; WS-635: IC₅₀ = 4.13 μmol/L) and thus represent novel scaffolds for designing new SHP2-PTP inhibitors. TK-147, an allosteric inhibitor, inhibited SHP2 potently (IC₅₀ = 0.25 μmol/L). In structure, TK-147 could be regarded as a bioisostere of the well characterized SHP2 inhibitor SHP-099, highlighting the essential structural elements for allosteric inhibition of SHP2. The principle underlying the cross-validation protocol is potentially feasible to identify allosteric inhibitors or those inactivating mutants of other proteins.
