The short stragglers "over there" are getting noticeably jittery.

Based on current activity, I believe serious discussions have taken place with at least one potential partner for Prurisol. Cellceutix seems to be checking off a list of items that are required to satisfy said partner. When you have three drugs (in totally different areas) to chose from, you go to these medical conferences and gauge the interest. It seems obvious to me that someone showed significant interest in Prurisol and that's why it has been pushed to the forefront.
