The cullin-RING ubiquitin ligases (CRLs) are ubiquitin E3 enzymes that play a key role in controlling proteasomal degradation and are activated by neddylation. We previously reported inhibitors that target CRL activation by disrupting the interaction of defective in cullin neddylation 1 (DCN1), a CRL neddylation co-E3, and UBE2M, a neddylation E2. Our first-generation inhibitors possessed poor oral bioavailability and fairly rapid clearance that hindered the study of acute inhibition of DCN-controlled CRL activity in vivo. Herein, we report studies to improve the pharmacokinetic performance of the pyrazolo-pyridone inhibitors. The current best inhibitor, 40, inhibits the interaction of DCN1 and UBE2M, blocks NEDD8 transfer in biochemical assays, thermally stabilizes cellular DCN1, and inhibits anchorage-independent growth in a DCN1 amplified squamous cell carcinoma cell line. Additionally, we demonstrate that a single oral 50 mg/kg dose sustains plasma exposures above the biochemical IC90 for 24 h in mice.

A series of 4-anilinopyrazolopyridine derivatives were synthesized and biologically evaluated as inhibitors of phosphodiesterase (PDE4). Chemical modification of 3, a structurally new chemical lead that was found in our in-house library, was focused on 1- and 3-substituents. Full details of the discovery of a new orally active chemical lead 5 are presented. Structure-activity relationship data, pharmacological evaluation, and the subtype selectivity study are also presented.

A series of novel (1,3-dialkyl-5-amino-1H-pyrazol-4-yl)arylmethanones was synthesized. Pharmacological evaluation of these compounds demonstrated central nervous system depressant activity, potential anticonvulsant properties, and a low order of acute toxicity. In addition, selected compounds showed potential antipsychotic effects. This report focuses on the synthesis and structure-activity relationships of these compounds. (5-Amino-1-ethyl-3-methyl-1H-pyrazol-4-yl)(2-chlorophenyl)methanone was the most active compound against pentylene-tetrazole-induced convulsions. (5-Amino-1,3-dimethyl-1H-pyrazol-4-yl)(3-chlorophenyl)methanone also has a favorable anticonvulsant depression ratio. (5-Amino-1,3-dimethyl-1H-pyrazol-4-yl)(3-trifluoromethylphenyl)methanone, (5-amino-1,3-dimethyl-1H-pyrazol-4-yl)(3-thienyl)methanone and (5-amino-3-ethyl-1-methyl-1H-pyrazol-4-yl)phenylmethanone are very potent depressants. (5-Amino-1,3-dimethyl-1H-pyrazol-4-yl)(2-thienyl)methanone possessed marked central depressant activity without anticonvulsant activity and without impairment of motor functioning. (5-Amino-1,3-dimethyl-1H-pyrazol-4-yl)(2-fluorophenyl)methanone has a behavioral profile suggestive of antipsychotic activity and gave a positive Ames test result.
