Bisoxazoline (BOX)-catalyzed asym. nucleophilic addition of di-Et zinc to fluorinated alkyl ketones successfully afforded enantioenriched fluorinated alkyl tertiary alcs. The effect of the size of the substituent on the oxazoline ring on the stereoselectivity of the reaction was investigated. Furthermore, the enantioselectivity could be reversed by altering the BOX bridge structure while retaining the C-4 substituent on the oxazoline ring.

Sameshima, Tomoya published the artcileDiscovery of an Irreversible and Cell-Active BCL6 Inhibitor Selectively Targeting Cys53 Located at the Protein-Protein Interaction Interface, Recommanded Product: 3-Chloro-4-fluoronitrobenzene, the publication is Biochemistry (2018), 57(8), 1369-1379, database is CAplus and MEDLINE.

B-cell lymphoma 6 (BCL6) is the most frequently involved oncogene in diffuse large B-cell lymphomas (DLBCLs). BCL6 shows potent transcriptional repressor activity through interactions with its corepressors, such as BCL6 corepressor (BCOR). The inhibition of the protein-protein interaction (PPI) between BCL6 and its corepressors suppresses the growth of BCL6-dependent DLBCLs, thus making BCL6 an attractive drug target for lymphoma treatments. However, potent small-mol. PPI inhibitor identification remains challenging because of the lack of deep cavities at PPI interfaces. This paper reports the discovery of a potent, cell-active, small-mol. BCL6 inhibitor, BCL6-i (8), that operates through irreversible inhibition. First, we synthesized an irreversible lead compound 4, which targets Cys53 in a cavity on the BCL6 BTB domain dimer by introducing an irreversible warhead to a high-throughput screening hit compound 1. Further chem. optimization of 4 based on kinact/KI evaluation produced BCL6-i with a kinact/KI value of 1.9 × 104 M-1s-1, corresponding to a 670-fold improvement in potency compared to 4. By exploiting the property of irreversible inhibition, engagement of BCL6-i to intracellular BCL6 was confirmed. BCL6-i showed intracellular PPI inhibitory activity between BCL6 and its corepressors, thus resulting in BCL6-dependent DLBCL cell-growth inhibition. BCL6-i is a cell-active chem. probe with the most potent BCL6 inhibitory activity reported to date. The discovery process of BCL6-i illustrates the utility of irreversible inhibition for identifying potent chem. probes for intractable target proteins.

Retinoic acid receptor related orphan receptor γt (RORγt), has been identified as the master regulator of T_H17-cell function and development, making it an attractive target for the treatment of autoimmune diseases by a small-mol. approach. Herein, we describe our investigations on a series of 4-aryl-thienyl acetamides, which were guided by insights from X-ray cocrystal structures. Efforts in targeting the cofactor-recruitment site from the 4-aryl group on the thiophene led to a series of potent binders with nanomolar activity in a primary human-T_H17-cell assay. The observation of a DMSO mol. binding in a subpocket outside the LBD inspired the introduction of an acetamide into the benzylic position of these compounds Hereby, a hydrogen-bond interaction of the introduced acetamide oxygen with the backbone amide of Glu379 was established. This greatly enhanced the cellular activity of previously weakly cell-active compounds The best compounds combined potent inhibition of IL-17 release with favorable PK in rodents, with compound 32 representing a promising starting point for future investigations.

P2Y₁₂ antagonists are widely used as antiplatelet agents for the prevention and treatment of arterial thrombosis. Based on the scaffold of a known P2Y₁₂ antagonist AZD1283 (I), a series of novel bicyclic pyridine derivatives were designed and synthesized. The cyclization of the ester substituent on the pyridine ring to the ortho-Me group led to lactone analogs of AZD1283 that showed significantly enhanced metabolic stability in subsequent structure-pharmacokinetic relationship studies. The metabolic stability was further enhanced by adding a 4-Me substituent to the piperidinyl moiety. Compound II displayed potent inhibition of platelet aggregation in vitro as well as antithrombotic efficacy in a rat ferric chloride model. Moreover, II showed a safety profile that was superior to what was observed for clopidogrel in a rat tail-bleeding model. These results support the further evaluation of compound II as a promising drug candidate.
