A silver-mediated synthesis of α-amino ketones via the oxidative deconstruction of azetidinols has been developed using a readily scalable protocol with isolated yields up to 80percent. The azetidinols are easily synthesized in one step and can act as protecting groups for these pharmaceutically relevant synthons. Furthermore, mechanistic insights are presented and these data have revealed that the transformation is likely to proceed through the β-scission of an alkoxy radical, followed by oxidation and C-N cleavage of the resulting α-amido radical.

A series of β-azole-phenylacetone derivatives with novel structures were designed and synthesized to combat the increasing incidence of susceptible fungal infections and drug-resistant fungal infections. The antifungal activity of the synthesized compounds was assessed against five susceptible strains and five fluconazole-resistant strains. Antifungal activity tests showed that most of the compounds exhibited excellent antifungal activities against five pathogenic strains with MIC values in the range of 0.03–1 μg/mL. Compounds with R1 = 3-F substituted and 15o and 15ae exhibited moderate antifungal activities against fluconazole-resistant strains 17# and CaR with MIC values in the range of 1–8 μg/mL. Compounds with R1 = H or 2-F (such as 15a, 15o, 15p) displayed moderate to good antifungal activity against fluconazole-resistant strains 632, 901 and 904 with MIC values in the range of 0.125–4 μg/mL. Notably, 15o and 15ae exhibited antifungal activity against five susceptible strains and five fluconazole-resistant strains. Preliminary mechanistic studies showed that the potent antifungal activity of compound 15ae stemmed from inhibition of C. albicans CYP51. Compounds 15o, 15z and 15ae were nearly nontoxic to mammalian A549 cells.

The discovery and optimization of Δ-5 desaturase (D5D) inhibitors are described. Investigation of the 1,3-oxazolidin-2-one scaffold was inspired by a pharmacophore model constructed from the common features of several hit compounds, resulting in the identification of 3,5-diphenyl-1,3-oxazolidin-2-one 5h as a novel lead showing potent in vitro activity. Subsequent optimization focused on the modification of two metabolic sites, which provided (4S,5S)-5i, a derivative with improved metabolic stability. Moreover, adding a substituent into the upper phenyl moiety further enhanced the intrinsic activity, which led to the discovery of 5-[(4S,5S)-5-(4fluorophenyl)-4-methyl-2-oxo-1,3-oxazolidin-3-yl]benzene-1,3-dicarbonitrile (4S,5S)-5n, endowed with excellent D5D binding affinity, cellular activity, and high oral bioavailability in a mouse. It exhibited robust in vivo hepatic arachidonic acid/dihomo-γ-linolenic acid ratio reduction (a target engagement marker) in an atherosclerosis mouse model. Finally, an asymmetric synthetic procedure for this compound was established.

Inhibition of sphingosine-1-phosphate lyase has recently been proposed as a potential treatment option for inflammatory disorders such as multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease. In this report we describe our hit-to-lead evaluation of the isoxazolecarboxamide 6, a high-throughput screening hit (in vitro IC50 = 1.0 μM, cell IC50 = 1.8 μM), as a novel S1P lyase inhibitor. We were able to establish basic structure-activity relationships around 6 and succeeded in obtaining X-ray structural information which enabled structure-based design. With the discovery of 28, enzyme activity was quickly improved to IC50 = 120 nM and cell potency to IC50 = 230 nM. The main liability in the established isoxazolecarboxamide hit series was determined to be metabolic stability. In particular we identified that future lead-optimization efforts to overcome this problem should focus on blocking the N-dealkylation on the secondary amine.
