Flexibility and communication: A series of di- and polynitroxide amides possessing 2,2,5,5-tetramethyl-1-pyrrolidinyloxy (PROXYL) and/or 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO) units were synthesized and their properties were analyzed through multiple experimental techniques, including X- and Q-band EPR spectroscopy, X-ray diffraction, cyclic voltammetry, and DFT calculations (see figure). An assessment of their inhibitory activities against selected bacteria, yeasts, and filamentous fungi revealed the highest activity for TEMPO-derived tetraradicals.

聚自由基PROXYL / TEMPO衍生的酰胺：合成，物化研究，DFT计算和抗菌活性

灵活性和沟通性：一系列具有2,2,5,5-四甲基-1-吡咯烷氧基（PROXYL）和/或2,2,6,6-四甲基-1-哌啶基氧基（TEMPO）的二硝基和聚硝基酰胺是通过多种实验技术，包括X波段和Q波段EPR光谱，X射线衍射，循环伏安法和DFT计算，分析了它们的合成及其性质。对它们对所选细菌，酵母和丝状真菌的抑制活性的评估显示，TEMPO衍生的四基自由基的活性最高。
