  针对 SARS-CoV-2 的氯硝柳胺类似物的设计、合成和生物学评价

  摘要：

  氯硝柳胺是一种广泛使用的驱虫药，通过TMEM16F抑制和自噬诱导复制来抑制SARS-CoV-2病毒进入，但相对较高的细胞毒性和较差的口服生物利用度限制了其应用。我们合成了 22 种氯硝柳胺类似物，其中发现化合物5具有最佳的抗 SARS-CoV-2 功效（IC 50  = 0.057 μM)和化合物6、10和11（IC 50 = 0.39、0.38 和 0.49 μM，分别）显示出与氯硝柳胺相当的功效。另一方面，化合物5、6、11在人血浆和肝脏S9酶测定中比氯硝柳胺具有更高的稳定性，口服给药时可以提高生物利用度和半衰期。荧光显微镜显示，与氯硝柳胺相比，化合物5在减少磷脂酰丝氨酸外化方面表现出更好的活性，这与 TMEM16F 抑制有关。应用人工智能预测的人TMEM16F蛋白结构进行分子对接，揭示5的4′-NO 2与Arg809形成氢键，而氯硝柳胺则被2′-Cl阻断。

  Antagonists for the ATP-gated ion channel receptor P2X1 have potential as antithrombotics and for treating hyperactive bladder and inflammation. In this study, salicylanilide derivatives were synthesized based on a screening hit. P2X1 antagonistic potency was assessed in 1321N1 astrocytoma cells stably transfected with the human P2X1 receptor by measuring inhibition of the ATP-induced calcium influx. Structure-activity relationships were analyzed, and selectivity versus other P2X receptor subtypes was assessed. The most potent compounds, N-[3,5-bis(trifluoromethyl)phenyl]-5-chloro-2-hydroxybenzamide (1, IC50 0.0192 mu M) and N-[3,5-bis(trifluoromethyl)phenyl]-4-chloro-2-hydroxybenzamide (14, IC50 0.0231 mu M), displayed >500-fold selectivity versus P2X2 and P2X3, and 10-fold selectivity versus P2X4 and P2X7 receptors, and inhibited collagen-induced platelet aggregation. They behaved as negative allosteric modulators, and molecular modeling studies suggested an extracellular binding site. Besides selective P2X1 antagonists, compounds with ancillary P2X4 and/or P2X7 receptor inhibition were discovered. These compounds represent the first potent, non-acidic, allosteric P2X1 receptor antagonists reported to date.
• Identification and synthesis of low-molecular weight cholecystokinin B receptor (CCKBR) agonists as mediators of long-term synaptic potentiation

  Recently, He et al. reported that CCKB receptors located in the neocortex of the brain when bound to their bound natural ligand, CCK peptides, enhance memory, bringing up the possibility that agonists targeting the CCKB receptor may act as therapeutic agents in diseases in which memory loss is marked as observed in dementia and Alzheimer's. In this report, we describe the synthesis of novel low-molecular weight benzoamine CCKB receptor agonists. The compounds made in this series were determined to be mostly partial agonists, although some antagonists were identified, as well, capable of triggering calcium release in a cell line that overexpresses the CCKB receptor. Compound 35 demonstrated an EC50 of 0.15 mu M in the cell-based assay, but more importantly, several of the compounds, including 35, demonstrated a physiological effect, inducing long-term potentiation in rat brains comparable to the CCK-8 peptide albeit at much higher concentrations. Based on these findings, benzoamines may be the basis for a new series of CCKB receptor agonists in drug-discovery efforts that seek to develop therapeutics to prevent memory loss.

  The Wnt signal transduction pathway is dysregulated in many highly prevalent diseases, including cancer. Unfortunately, drug discovery efforts have been hampered by the paucity of targets and drug-like lead molecules amenable to drug discovery. Recently, we reported the FDA-approved anthelmintic drug Niclosamide inhibits Wnt/beta-catenin signaling by a unique mechanism, though the target responsible remains unknown. We interrogated the mechanism and structure-activity relationships to understand drivers of potency and to assist target identification efforts. We found inhibition of Wnt signaling by Niclosamide appears unique among the structurally-related anthelmintic agents tested and found the potency and functional response was dependent on small changes in the chemical structure of Niclosamide. Overall, these findings support efforts to identify the target of Niclosamide inhibition of Wnt/beta-catenin signaling And the discovery of potent and selective modulators to treat human disease.
