Apan (PPI-1019) is the lead compound of a series of β-amyloid-derived peptides designed by Praecis Pharmaceuticals in the US to interact with β-amyloid peptide, facilitating its clearance. Apan is derived from the D-enantiomeric Cholyl-LVFFA-NH2. Apan is developed by Praecis Pharmaceuticals to treat Alzheimer's Disease. Apan inhibits the aggregation of beta-amyloid and its associated nerve cell toxicity. In addition, Apan reaches the brain in quantities that are sufficient to block the aggregation of beta-amyloid molecules and alter the course of the disease. PPI-1019 completed phase I and II clinical trials and was found to be safe, well tolerated and amenable to cross bbb. After peptide administration, levels of Aβ1-40 in the CSF increased, which might be discussed as a sign for Aβ clearance out of the brain. PI-1019 had been in phase I/II clinical trials by Praecis Pharmaceuticals (acquired by GlaxoSmithKline in 2007) for the treatment of Alzheimer's disease(AD). However, this study had been discontinued.

PRIMARY | PPI-1019 (Apan) inhibits the aggregation of beta-amyloid and its associated nerve cell toxicity. In addition, Apan reaches the brain in quantities that are sufficient to block the aggregation of beta-amyloid molecules and alter the course of the disease. Accumulation of beta-amyloid in the brain is often thought of as a defect in the ability to clear beta-amyloid from the brain through the cerebral spinal fluid (CSF). Both humans and transgenic mice with Alzheimer's disease plaques show increased levels of beta-amyloid in the brain and decreased levels in the CSF. Transgenic mice treated with Apan show significant increases in beta-amyloid levels in the CSF, indicating that Apan is able to mobilize beta-amyloid in the brain and may be facilitating its clearance. | ||

ACTIVE MOIETY |
Unfortunately, PPI-368 was proteolysed in plasma, precluding therapeutic use. However, several all-D amino-acid-containing peptides based on Abeta residues 1721 were also found to be effective aggregation inhibitors, including PPI-1019 (compound 11), which is now a candidate for clinical studies.
