It came up in a search on Google scholar, I was hoping that the findings that Tanzi alluded to in the shareholders letter (see below) might have been published somewhere, which might explain the interest

We have been using Alzheimer’s-in-a-Dish to find drugs that will slow or halt plaque and tangle formation. Among those that are being tested is PBT2. Studies of PBT2 are still in progress and once confirmed, will be submitted for publication. So far, the preliminary findings show that PBT2 has the following effects in Alzheimer’s-in-a-Dish: 1. A trend in the direction of attenuation of the aggregation and fibrillization of the Abeta peptide into betaamyloid, 2. significantly reduced tangle formation, and 3. significantly increased cell viability. Once these results are confirmed, PBT2 would become the only compound tested in Alzheimer’s-in-a-Dish to achieve all three of these effects on AD pathology.
