An Efficient Approach to 3-Bromo-6-chloro-phenanthrene-9,10-dione
摘要:
A practical and efficient synthesis of 3-bromo-6-chloro-phenanthrene-9,10-dione was developed and demonstrated on a large scale. The synthetic approach involves six chemical steps and two isolations in 73% overall yield. The key transformations feature an anionic cyclization for generation of the phenanthrene ring, followed by sequential tribromination and hydrolysis for the incorporation of the bromo-diketone functionality.

The invention encompasses novel compounds of Formula I
or pharmaceutically acceptable salts thereof. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and are therefore useful to treat pain and/or inflammation from a variety of diseases or conditions, such as osteoarthritis, rheumatoid arthritis and acute or chronic pain. Methods of treating diseases or conditions mediated by the mPGES-1 enzyme and pharmaceutical compositions are also encompassed.

The invention encompasses a method for making an amorphous solid of a water-insoluble pharmaceutical comprising: (1) dissolving the water-insoluble pharmaceutical in a water-miscible solvent, optionally with water, to make a solution; (2)(i) rapidly mixing the solution with an antisolvent, wherein the antisolvent is water, at low temperature to precipitate an amorphous solid of the water-insoluble pharmaceutical, or (ii) rapidly mixing the solution with an antisolvent, wherein the antisolvent is water, to precipitate an amorphous solid of the water-insoluble pharmaceutical and subsequently cooling to low temperature; and (3) isolating the amorphous solid of the water-insoluble pharmaceutical. In an embodiment of the invention, the rapid mixing is conducted using an impinging jet device.
The present invention is directed to a method for treating or preventing a neoplasia in a human patient in need of such treatment comprising administering to the patient a compound that inhibits microsomal prostaglandin E synthase-1 in an amount that is effective for treating or preventing the neoplasia.
