Tankyrases 1 and 2 are central biotargets in the WNT/闁?catenin signaling and Hippo signaling pathways. We have previously developed tankyrase inhibitors bearing a 1,2,4-triazole moiety and binding predominantly to the adenosine binding site of the tankyrase catalytic domain. Here we describe a systematic structure-guided lead optimization approach of these tankyrase inhibitors. The central 1,2,4-triazole template and trans-cyclobutyl linker of the lead compound 1 (I) were left unchanged, while side-group East, West, and South moieties were altered by introducing different building blocks defined as point mutations. The systematic study provided a novel series of compounds reaching picomolar IC50 inhibition in WNT/闁?catenin signaling cellular reporter assay. The novel optimized lead 13 (II) resolves previous atropisomerism, solubility, and Caco-2 efflux liabilities. 13 Shows a favorable ADME profile, including improved Caco-2 permeability and oral bioavailability in mice, and exhibits antiproliferative efficacy in the colon cancer cell line COLO 320DM in vitro. In the experiment, the researchers used many compounds, for example, 1H-Pyrrolo[2,3-b]pyridine-6-carboxylic acid (cas: 898746-35-5HPLC of Formula: 898746-35-5).
1H-Pyrrolo[2,3-b]pyridine-6-carboxylic acid (cas: 898746-35-5) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. In addition to indole, the strain-release chemistry worked for numerous substrates including amines, alcohols, thiols, carboxylic acids, imidazoles, and pyrazoles.HPLC of Formula: 898746-35-5
