Combination of click chemistry and sulfonamides to develop three-armed triazole compounds

Syntheses and Biological Activities of triazole-based Sulfonamides

:

The triazole and sulfonamide compounds are known as biologically active agents that were employed for medicinal applications. These compounds were obtained in different forms by a variety of techniques to vast ranges of applications. The broad biological properties of these compounds have encouraged researchers to design and synthesize triazole-based sulfonamide derivatives as compounds with potential biological activity. In this review, we summarized the synthetic procedures of triazole-based sulfonamide compounds together with their biological activities during the last two decades.

Chirality sensing of bioactive compounds with amino alcohol unit via circular dichroism

The aim of the present work was to test various chiroptical techniques, including in particular the in situ dirhodium methodology, to assign the absolute configuration of 1,2- and 1,3-amino alcohols. As models, we selected mainly compounds that have both an additional strongly absorbing and interfering chromophoric system and application in medicinal chemistry. Determination of the absolute configuration (AC) of the tested molecules such as cinchona alkaloids, Tamiflu, and others was carried out using a combination of electronic and vibrational circular dichroism (ECD, VCD) spectroscopy. It has been demonstrated that both 1,2- and 1,3-aminol moieties are subject to the same sector rule correlating stereostructure of formed Rh₂ -complex with chiroptical properties, and that the changes in the position of the stereogenic center do not affect its proper use.
