Фулеропиролидини са ортогонално флексибилним супституентима – синтеза и електрохемијске особине

A large series of disubstituted fulleropyrrolidines was synthesized and analyzed by cyclic voltammetry. The three main groups of target com­pounds differ by a flexible N-chain, while their further diversity was achieved by the introduction of various rigid, aryl substituents at the pyrrolidine carbon. Some dialkyl analogues were also designed for comparison, A standard [3+2]-cycloaddition of in situ generated azomethine ylides to C60 afforded a variety of disubstituted fulleropyrrolidines. Furthermore, a set of dumbbell-shaped di(fulleropyrrolidine) derivatives containing rigid fumaryl or isophthaloyl diamide platform was prepared with the aim of investigating a long-range effect of the second fulleropyrrolidine moiety on their electrochemical pro­perties. All compounds were fully characterized by comparative analysis of spectral data, while examination of electrochemical properties was performed on representative samples, distinguished by main structural subunits. All com­pounds expressed quite similar electron-accepting ability, lower than C60, but higher in comparison to structurally similar N-methylfulleropyrrolidine.Велика серија дисупституисаних фулеропиролидина је синтетисана и анализирана цикличном волтаметријом. Три главне групе циљних једињења разликују се по флекси- билном бочном низу на атому азота, а додатна диверсификација постигнута је увођењем различитих крутих, арил-супституената на пиролидинском атому угљеника. За поре- ђење су синтетисани и одређени диалкил-аналози. Сет дисупституисаних фулеропиро- лидина добијен је стандардном [3+2]-циклоадицијом ин ситу генерисаних азометинских илида на C60. Осим тога, у циљу испитивања даљинског утицаја фулеропиролидинске структуре на електрохемијске особине, синтетисани су и дифулеренски деривати код којих су терминално позициониране фулеренске подјединице премошћене фумарилном или изофталоилном крутом платформом. Сва једињења су у потпуности окарактерисана упоредном анализом спектралних података, док је сет одабраних једињења, са разли- кама у главним структурним подјединицама, искоришћен за испитивање електрохемиј- ских особина. Сва испитивана једињења показала су врло сличну способност прихватања електрона, нижу у односу на C60, а вишу од структурно сличног N-метилфулеропиро- лидина

Synthesis and determination of in vitro biological activity of novel fulleropyrrolidines containing phenol subunit

Willing to obtain novel fulleropyrrolidines with improved biological activity, we explored the synthesis of hybrid structures containing fullerene and phenol. The Prato reaction of the glycine derivative, aromatic aldehydes with phenol subunit and the fullerene C60 provided desired products in satisfactory yields (Figure 1). DPPH radical scavenging activity and β–carotene-linoleic acid bleaching assay were used to determinate antioxidant activity, while for evaluation of anti-inflammatory activity, ovalbumin (OVA) and bovine serum albumin (BSA) thermal denaturation inhibition assays were used. Obtained results indicated that performed synthesis gave rise to compounds with dual activity
