Continuous optimization of benzylic substituents on 1-(4-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)piperazin-1-yl)-2-phenylethan-1-one structure as Akt inhibitors was described in this paper. Particularly, compounds 8 and 14g exhibited high enzymatic potency against all Akt isoforms and antiproliferative effects in mantle cell lymphoma cell lines, as well as favorable cytotoxicities in patient primary cancer cells. Low micromolar doses of both 8 and 14g dose-dependently induced cell apoptosis and G2/M cell cycle arrest, also suppressed the phosphorylation level of Akt downstream targets GSK3β and S6.

Nuclear factor erythroid 2-related factor 2 (NRF2) is a pleiotropic transcription factor which regulates the constitutive and inducible transcription of a wide array of genes and confers protection against a variety of pathologies. Directly disrupting Kelch-like ECH-associated protein 1 (KEAP1)-NRF2 protein-protein interaction (PPI) has been explored as a promising strategy to activate NRF2. We reported here the first identification of a series of 2-oxy-2-phenylacetic acid substituted naphthalene sulfonamide derivatives as potent KEAP1-NRF2 inhibitors. Our efforts led to the potent small molecule KEAP1-NRF2 inhibitor, 20c, which exhibited a Kd of 24 nM to KEAP1 and an IC50 of 75 nM in disrupting KEAP1-NRF2 interaction. Subsequent biological studies provided consistent evidence across mouse macrophage cell-based and in vivo models that 20c induced NRF2 target gene expression and enhanced downstream antioxidant and anti-inflammatory activities. Our study not only demonstrated that small molecule KEAP1-NRF2 PPI inhibitors can be potential preventive and therapeutic agents for diseases and conditions involving oxidative stress and inflammation but also enriched the chemical diversity of the KEAP1-NRF2 inhibitors.

A diastereo- and enantioselective propargylic substitution reaction between propargylic carbonates and α-substituted nitroacetates catalyzed by a Cu-pybox complex is described. This method allows the preparation of a series of non-proteinogenic quaternary α-amino acid precursors featuring two contiguous stereogenic centers and a terminal alkyne moiety in high yields with good to excellent diastereo- and enantioselectivities in most cases. The propargylated adducts were elaborated into a diverse set of quaternary α-amino acid derivatives.

New 4-aryl-1,3,2-oxathiazolylium-5-olates: Chemical synthesis and photochemical stability of a novel series of S-nitrosothiols

S-nitrosothiols (RSNOs) remain one of the most popular classes of NO-donating compounds due to their ability to release nitric oxide (NO) under non-enzymatic means whilst producing an inert disulphide by-product. However, alligning these compounds to the different biological fields of NO research has proved to be problematic due to the inherent instability of such compounds under a variety of conditions including heat, light and the presence of copper ions. 1,3,2-Oxathiazolylium-5-olates (OZOs) represent an interesting subclass of S-nitrosothiols that lock the –SNO moiety into a five membered heterocyclic ring in an attempt to improve the compound's overall stability. The synthesis of a novel series of halogen-containing OZOs was comprehensively studied resulting in a seven-step route and overall yields ranging between 21 and 37%. The photochemical stability of these compounds was assessed to determine if S-nitrosothiols locked within these mesoionic ring systems can offer greater stability and thereby release NO in a more controllable fashion than their non-cyclic counterparts.

We herein describe the results of further evolution of glycogen synthase kinase (GSK)-3β inhibitors from our promising compounds containing a 2-phenylmorpholine moiety. Transformation of the morpholine moiety into a piperazine moiety resulted in potent GSK-3β inhibitors. SAR studies focused on the phenyl moiety revealed that a 4-fluoro-2-methoxy group afforded potent inhibitory activity toward GSK-3β. Based on docking studies, new hydrogen bonding between the nitrogen atom of the piperazine moiety and the oxygen atom of the main chain of Gln185 has been indicated, which may contribute to increased activity compared with that of the corresponding phenylmorpholine analogues. Effect of the stereochemistry of the phenylpiperazine moiety is also discussed.
