Bis(4-fluorophenyl) substituted oxazole (2,5-Oxz) and C2(5)-C2?(5?) linked bioxazole isomers (C2-C2?_BOxz, C2-C5?_BOxz and C5-C5?_BOxz) were concisely synthesized via palladium-catalyzed regioselective and sequential C[sbnd]H arylation in 1–3 reaction steps along with 20%–83% of total yields from oxazole and 4-bromofluorobenzene. The linking orientation plays a key role in the packing geometry and photophysical properties of C2-C2'_BOxz, C2-C5'_BOxz and C5-C5'_BOxz. These bioxazole isomers in solid state showed significant differences in photoluminescence quantum yields (PLQY) (0.33, 0.25 and 0.04, respectively), delayed fluorescence properties and powder X-ray diffraction (PXRD) patterns, suggesting the divergence in intermolecular interactions. The theoretically calculated gradient isosurfaces and complexation energies indicate the existence of intense π-π interactions between molecular layers, which are in good agreement with the variation trend of optical properties.

The present application provides novel pyridine compounds and pharmaceutically acceptable salts or prodrugs thereof. Also provided are methods for preparing these compounds. These compounds are useful in inhibiting CYP 17 activity by administering a therapeutically effective amount of one or more of the compounds to a patient. By doing so, these compounds are effective in treating conditions associated with CPY17 activity. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment, the disease is cancer, such as prostate cancer.
