The crystal structure of the (4S,5R)-5-[3,5-bis(trifluoromethyl)phenyl]-4- methyl-1,3-oxazolidin-2-one has been determined by single crystal X-ray diffraction method. The compound crystallizes in the monoclinic system, space group P2(1) with a = 11.867(4) ?, b = 5.6968(19) ?, c = 20.258(7) ?, α = 90.00°, β = 91.866(4)°, γ = 90.00°, Z = 4, V = 1368.8(8) ?3, Dx = 1.520 Mg/m3, F (000) = 632, μ(MoKα) = 0.157 mm-1, R = 0.0562 and wR = 0.1744 for 3675 reflections with I > 2σ(I). X-Ray analysis reveals that the benzene and oxazolidin rings are non-coplanar. The oxazolidin ring displays a twist conformation. The two molecules interact with each other by two strong N-H···O hydrogen bonds. Herein, we report the synthesis and crystal structure of (4S,5R)-5-[3,5- bis(trifluoromethyl)phenyl]-4-methyl-1,3-oxazolidin-2-one.

We describe our optimization efforts to improve the physicochemical properties, solubility, and off-target profile of 1, an inhibitor of TarO, an early stage enzyme in the biosynthetic pathway for wall teichoic acid (WTA) synthesis. Compound 1 displayed a TarO IC50 of 125 nM in an enzyme assay and possessed very high lipophilicity (clogP = 7.1) with no measurable solubility in PBS buffer. Structure-activity relationship (SAR) studies resulted in a series of compounds with improved lipophilic ligand efficiency (LLE) consistent with the reduction of clogP. From these efforts, analog 9 was selected for our initial in vivo study, which in combination with subefficacious dose of imipenem (IPM) robustly lowered the bacterial burden in a neutropenic Staphylococci murine infection model. Concurrent with our in vivo optimization effort using 9, we further improved LLE as exemplified by a much more druglike analog 26.
