Structure-based design of PDZ ligands as inhibitors of 5-HT2A Receptor/PSD-95 PDZ1 domain interaction possessing anti-hyperalgesic activity

Disrupting the interaction between the PDZ protein PSD-95 and the C-terminal domain of the 5-HT2A serotonin receptor has been shown to reduce hyperalgesia in a rodent model of neuropathic pain. Here, we designed and synthesized PDZ ligands capable of binding to the first PDZ domain (PDZ1) of the PSD-95 protein and evaluated their biological activity in vitro and in vivo. A series of substituted indoles was identified by docking simulations, and six novel analogues were synthesized. Three analogues displayed strong interactions with the first PDZ domain (PDZ1) of PDZ-95 in 1H-15N heteronuclear single-quantum coherence (HSQC) experiments and two of them were able to inhibit the interaction between PSD-95 and the 5-HT2A receptor in vitro. We identified compound 8b as the analogue able to significantly suppress mechanical hyperalgesia in an experimental model of traumatic neuropathic pain in the rat. This effect was suppressed by the coadministration of the 5-HT2A receptor antagonist M100907, consistent with an inhibitory effect upon 5-HT2A receptor/PSD-95 interaction. Finally, we determined an NMR-restraint driven model structure for the PSD95 PDZ1/8b complex, which confirms that indole 8b binds to the putative PDZ-ligand binding site.

Identification of (R)-6-(1-(4-cyano-3-methylphenyl)-5-cyclopentyl-4,5- dihydro-1H-pyrazol-3-yl)-2-methoxynicotinic acid, a highly potent and selective nonsteroidal mineralocorticoid receptor antagonist

A novel series of nonsteroidal mineralocorticoid receptor (MR) antagonists identified as part of our strategy to follow up on the clinical candidate PF-03882845 (2) is reported. Optimization departed from the previously described pyrazoline 3a and focused on improving the selectivity for MR versus the progesterone receptor (PR) as an approach to avoid potential sex-hormone-related adverse effects and improving biopharmaceutical properties. From this effort, (R)-14c was identified as a potent nonsteroidal MR antagonist (IC50 = 4.5 nM) with higher than 500-fold selectivity versus PR and other related nuclear hormone receptors, with improved solubility as compared to 2 and pharmacokinetic properties suitable for oral administration. (R)-14c was evaluated in vivo using the increase of urinary Na+/K+ ratio in rat as a mechanism biomarker of MR antagonism. Treatment with (R)-14c by oral administration resulted in significant increases in urinary Na +/K+ ratio and demonstrated this novel compound acts as an MR antagonist.
