Structure-Activity Study of Nitazoxanide Derivatives as Novel STAT3 Pathway Inhibitors

We identified nitazoxanide (NTZ) as a moderate STAT3 pathway inhibitor through immunoblot analysis and a cell-based IL-6/JAK/STAT3 pathway activation assay. A series of thiazolide derivatives were designed and synthesized to further validate the thiazolide scaffold as STAT3 inhibitors. Eight out of 25 derivatives displayed potencies greater than that of NTZ, and their STAT3 pathway inhibitory activities were found to be significantly correlated with their antiproliferative activities in HeLa cells. Derivatives 15 and 24 were observed to be more potent than the positive control WP1066, which is under phase I clinical trials. Compared with NTZ, 15 also exhibited much improved in vivo pharmacokinetic parameters in rats and efficacies against proliferations in multiple cancer cell lines, indicating a broad-spectrum effect of these thiazolides as antitumor agents targeted on STAT3.

Design, synthesis, biological evaluation and pharmacophore model analysis of novel tetrahydropyrrolo[3,4-c]pyrazol derivatives as potential TRKs inhibitors

The tropomyosin receptor kinases TRKs are responsible for different tumor types which caused by NTRK gene fusion, and have been identified as a successful target for anticancer therapeutics. Herein, we report a potent and selectivity TRKs inhibitor 19m through rational drug design strategy from a micromolar potency hit 17a. Compound 19m significantly inhibits the proliferation of TRK-dependent cell lines (Km-12), while it has no inhibitory effect on TRK-independent cell lines (A549 and THLE-2). Furthermore, kinases selectivity profiling showed that in addition to TRKs, compound 19m only displayed relatively strong inhibitory activity on ALK. These data may indicate that compound 19m has a good drug safety. Partial ADME properties were evaluated in vitro and in vivo. Compound 19m exhibited a good AUC values and volume of distribution and low clearance in the pharmacokinetics experiment of rats. Finally, a pharmacophore model guided by experimental results is proposed. We hope this theoretical model can help researchers find type I TRK inhibitors more efficiently.

Synthesis, Identification, and Structure-Activity Relationship Analysis of GATA4 and NKX2-5 Protein-Protein Interaction Modulators

Transcription factors GATA4 and NKX2-5 directly interact and synergistically activate several cardiac genes and stretch-induced cardiomyocyte hypertrophy. Previously, we identified phenylisoxazole carboxamide 1 as a hit compound, which inhibited the GATA4-NKX2-5 transcriptional synergy. Here, the chemical space around the molecular structure of 1 was explored by synthesizing and characterizing 220 derivatives and structurally related compounds. In addition to the synergistic transcriptional activation, selected compounds were evaluated for their effects on transcriptional activities of GATA4 and NKX2-5 individually as well as potential cytotoxicity. The structure-activity relationship (SAR) analysis revealed that the aromatic isoxazole substituent in the southern part regulates the inhibition of GATA4-NKX2-5 transcriptional synergy. Moreover, inhibition of GATA4 transcriptional activity correlated with the reduced cell viability. In summary, comprehensive SAR analysis accompanied by data analysis successfully identified potent and selective inhibitors of GATA4-NKX2-5 transcriptional synergy and revealed structural features important for it.

Ni-Catalyzed cross-coupling reactions of N-acylpyrrole-type amides with organoboron reagents

The catalytic conversion of amides to ketones is highly desirable yet challenging in organic synthesis. We herein report the first Ni/bis-NHC-catalyzed cross-coupling of N-acylpyrrole-type amides with arylboronic esters to obtain diarylketones. This method is facilitated by a new chelating bis-NHC ligand. The reaction tolerates diverse functional groups on both arylamide and arylboronic ester partners including sensitive ester and ketone groups.
