- Discovery and Development of N-[4-(1-Cyclobutylpiperidin-4-yloxy)phenyl]-2-(morpholin-4-yl)acetamide Dihydrochloride (SUVN-G3031): A Novel, Potent, Selective, and Orally Active Histamine H3 Receptor Inverse Agonist with Robust Wake-Promoting Activity
-
A series of chemical optimizations guided by in vitro affinity at a histamine H3 receptor (H3R), physicochemical properties, and pharmacokinetics in rats resulted in identification of N-[4-(1-cyclobutyl-piperidin-4-yloxy)phenyl]-2-(morpholin-4-yl)acetamide dihydrochloride (17v, SUVN-G3031) as a clinical candidate. Compound 17v is a potent (hH3R Ki = 8.73 nM) inverse agonist at H3R with selectivity over other 70 targets, Compound 17v has adequate oral exposures and favorable elimination half-lives both in rats and dogs. It demonstrated high receptor occupancy and marked wake-promoting effects with decreased rapid-eye-movement sleep in orexin-B saporin lesioned rats supporting its potential therapeutic utility in treating human sleep disorders. It had no effect on the locomotor activity at doses several fold higher than its efficacious dose. It is devoid of hERG and phospholipidosis issues. Phase-1 evaluation for safety, tolerability, and pharmacokinetics, and long-term safety studies in animals have been successfully completed without any concern for further development.

- Benzamide capped peptidomimetics as non-ATP competitive inhibitors of CDK2 using the REPLACE strategy
-
Inhibition of cyclin dependent kinase 2 (CDK2) in complex with cyclin A in G1/S phase of the cell cycle has been shown to promote selective apoptosis of cancer cells through the E2F1 pathway. An alternative approach to catalytic inhibition is to target the substrate recruitment site also known as the cyclin binding groove (CBG) to generate selective non-ATP competitive inhibitors. The REPLACE strategy has been applied to identify fragment alternatives and substituted benzoic acid derivatives were evaluated as a promising scaffold to present appropriate functionality to mimic key peptide determinants. Fragment Ligated Inhibitory Peptides (FLIPs) are described which potently inhibit both CDK2/cyclin A and CDK4/cyclin D1 and have preliminary anti-tumor activity. A structural rationale for binding was obtained through molecular modeling further demonstrating their potential for further development as next generation non ATP competitive CDK inhibitors.

- Synthesis and evaluation of 2′-substituted 4-(4′-carboxy- or 4′-carboxymethylbenzylidene)-N-acylpiperidines: Highly potent and in vivo active steroid 5α-reductase type 2 inhibitors
-
Sixteen compounds derived from N-acyl-4-benzylidenepiperidine-4′-carboxylic acids were synthesized and evaluated for inhibition of rat and human steroid 5α-reductase isozymes types 1 and 2. In the dicyclohexylacetyl series, fluorination in the 2-position of the benzene nucleus (15), exchange of the carboxy group by a carboxymethyl moiety (20), and combination of both structural modifications (25) led to highly active inhibitors of the human type 2 isozyme (IC50 values: 15, 11 nM; 20, 6 nM; 25, 7 nM; finasteride, 5 nM). In vivo all compounds tested markedly reduced the prostate weights in castrated testosterone-treated rats. Oral activity was shown for compound 7. From the finding that compound 15 is active in the rat, although it is a rather poor inhibitor of the rat enzyme and is a strong inhibitor of the human enzyme, it is concluded that it should be highly potent in men.
