Abstract
An effective one-pot strategy was developed for the synthesis of 4-arylpyrazolo[3,4-b]pyridin-6-ones from pyrazolo[3,4-b]pyridin-6-ones, obtained by reacting 5-aminopyrazoles with 4-arylidene-2-phenyloxazol-5(4H)-ones (azlactones) under solvent-free conditions, through subsequent elimination of a benzamide molecule in a superbasic medium (t-BuOK/DMSO). The fluorescent properties of the synthesized compounds were studied. 4-Arylpyrazolo[3,4-b]pyridin-6-ones luminesce in the region of 409-440 nm with a quantum yield of 0.09-0.23 when irradiated with UV light.

Abstract
![]()
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.

Abstract
Chemical control of cullin neddylation is attracting increased attention based largely on the successes of the NEDD8-activating enzyme (E1) inhibitor pevonedistat. Recently reported chemical probes enable selective and time-dependent inhibition of downstream members of the neddylation trienzymatic cascade including the co-E3, DCN1. In this work, we report the optimization of a novel class of small molecule inhibitors of the DCN1-UBE2M interaction. Rational X-ray co-structure enabled optimization afforded a 25-fold improvement in potency relative to the initial screening hit. The potency gains are largely attributed to additional hydrophobic interactions mimicking the N-terminal acetyl group that drives binding of UBE2M to DCN1. The compounds inhibit the protein-protein interaction, block NEDD8 transfer in biochemical assays, engage DCN1 in cells, and selectively reduce the steady-state neddylation of Cul1 and Cul3 in two squamous carcinoma cell lines harboring DCN1 amplification.
