    • Thermodynamic testing showed that 3 was a highly energetic substance with the potential for self-heating from 35 °C that could lead to explosion. This material should be used in small amounts and stored in a freezer. Solutions of 3 in methanol (1 M or less) were found to have reduced explosive potential and thus reactions at 23 °C were deemed to be of reduced risk. Nonetheless, appropriate safety procedures should be strictly observed when handling this compound.

    • The cdk5 homology model was built on in-house X-ray structures of cdk2-inhibitor complexes, and due to the high homology between the two, is very similar to the cdk2 X-ray structures themselves. Retrospectively, comparing the homology model to that of the reported cdk5-inhibitor complexes (Mapelli, M.; Massimiliano, L.; Crovace, C.; Seeliger, M. A.; Tsai, L.-H.; Meijer, L.; Musacchio, A. J. Med. Chem., 2005, 48, 671) reveals nearly identical residue-by-residue similarity.

    • cdk5 whole cell assay: A tetracycline-regulated expression system was used to produce a stable CHO cell line carrying inducible expression of human Cdk5, P25 and tau driven from modified pRevTRE Tet-Off vectors containing distinct antibiotic resistance genes. The cell line was maintained in the uninduced state in media containing doxycycline and then transgene induction was initiated by removal of doxycycline from the medium for 24 h. Following full induction of CDK5, P25, and tau, cells were incubated for 2 h with test compounds before lysis. Phosphorylated tau was measured in detergent-soluble extracts of cells using AlphaLISA (Perkin-Elmer). A capture antibody to total tau (HT7, Pierce) was conjugated to Acceptor beads, and a biotinylated phospho-epitope specific detection antibody (AT8, Pierce) was bound to streptavidin donor beads (Perkin-Elmer).
