The present invention relates to compositions which inhibit the binding of nerve growth factor to the p75NTR common neurotrophin receptor and methods of use thereof. In one embodiment, the compound which inhibits binding of nerve growth factor to p75NTR comprises, particularly when bound to nerve growth factor, at least two of the following: (1) a first electronegative atom or functional group positioned to interact with Lys34 of nerve growth factor; (2) a second electronegative atom or functional group positioned to interact with Lys95 of nerve growth factor; (3) a third electronegative atom or functional group positioned to interact with Lys88 of nerve growth factor; (4) a fourth electronegative atom or functional group positioned to interact with Lys32 of nerve growth factor; and (5) a hydrophobic moiety which interacts with the hydrophobic region formed by Ile31, Phe101 and Phe86 of nerve growth factor.
Design, Synthesis, and Biological Evaluation of New 5-HT<sub>4</sub> Receptor Agonists: Application as Amyloid Cascade Modulators and Potential Therapeutic Utility in Alzheimer’s Disease
based on the scaffold of ML10302, a highly specific and partial 5-HT4R agonist, were efficiently prepared by parallel supported synthesis and their binding affinities and agonist activities evaluated. Furthermore, we showed that, in vivo, the two best candidates exhibited neuroprotective activity by increasing the level of the soluble form of the amyloid precursor protein (sAPPα) in the cortex and hippocampus

Fluorescent scriptaid analogues with excellent HDAC6 selectivity (HDAC1/6 > 500) and potency (HDAC6 IC50 < 5 nM) have been synthesised and evaluated. The highly fluorescent nature of the compounds (up to Phi(F)= 0.83 in DMSO and 038 in aqueous buffer) makes them ideally suited for cellular imaging and visualisation of their cytoplasmic localisation was readily accomplished. Whole organism imaging in zebrafish confirmed both the vascular localisation of the new inhibitors and the impact of HDAC6 inhibition on in vivo development.
