Green by Design: Convergent Synthesis, Computational Analyses, and Activity Evaluation of New FXa Inhibitors Bearing Peptide Triazole Linking Units

Rodriguez, Diego F. ; Duran-Osorio, Francisca ; Duarte, Yorley ; Olivares, Pedro ; Moglie, Yanina ; Dua, Kamal , et al.

DOI: 10.3390/pharmaceutics14010033 PubMed ID: 35056929 Pharmaceutics,2022,14(1),33.

Abstract: Green chemistry implementation has led to promising results in waste reduction in the pharmaceutical industry. However, the early sustainable development of pharmaceutically active compounds and ingredients remains a considerable challenge. Herein, we wish to report a green synthesis of new pharmaceutically active peptide triazoles as potent factor Xa inhibitors, an important drug target associated with the treatment of diverse cardiovascular diseases. The new inhibitors were synthesized in three steps, featuring cycloaddition reactions (high atom economy), microwave-assisted organic synthesis (energy efficiency), and copper nanoparticle catalysis, thus featuring Earth-abundant metals. The molecules obtained showed FXa inhibition, with IC50-values as low as 17.2 μM and no associated cytotoxicity in HEK293 and HeLa cells. These results showcase the environmental potential and chemical implications of the applied methodologies for the development of new molecules with pharmacological potential.

Transition Metal‐Free Catalytic C− H Silylation of Terminal Alkynes with bis (Trimethylsilyl) acetylene Initiated by KHMDS

Krzysztof Kuciński ; Grzegorz Hreczycho ;

DOI: 10.1002/cctc.202200794 ChemCatChem,2022,14(18):e202200794.

Abstract: Commercially available and inexpensive potassium bis(trimethylsilyl)amide (KHMDS) serves as an efficient transition metal-free catalyst for the catalytic sp C−H silylation of several terminal alkynes including two pharmaceuticals. Overall, the presented system allows the synthesis of various attractive silylacetylenes under mild conditions, making this approach an environmentally benign and sustainable alternative to existing synthetic solutions.
