- Diversity-Oriented Synthesis of 1,2,4-Triazols, 1,3,4-Thiadiazols, and 1,3,4-Selenadiazoles from N-Tosylhydrazones
-
The diversity-oriented synthesis of 1,2,4-triazols, 1,3,4-thiadiazols, and 1,3,4-selenadiazoles from N-tosylhydrazones was developed, and the reactions were general for a wide range of substrates, in which NH2CN, KOCN, KSCN, and KSeCN were used as odorless sources. Two different pathways were proposed, and N-tosylhydrazonoyl chlorides were formed in situ in the presence of NCS.

- IMIDAZOLE DERIVATIVES AS CYP17 INHIBITORS FOR THE TREATMENT OF CANCER
-
The present application provides novel imidazole compounds and pharmaceutically acceptable salts 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.
