  Controlling the Pirouetting Motion in Rotaxanes by Counterion Exchange

  摘要：

  A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide rotaxanes. The present paper discusses the synthesis and the structural and dynamic characterizations of the first examples of anionic boron cluster-containing rotaxanes. To study the dynamic properties of such molecules, the pirouetting rate of the weakly coordinating boron cluster-containing rotaxanes with the more strongly coordinating trifluoroacetate anion (TFA(-)), which would form a close ion pair with the macrocycle, was measured using the exchange spectroscopy NMR technique. Our hypothesis was that the stronger the ion pair the lower the rate of rotation due to the presence of a bigger volume of solvent to be moved. The anion would act as an anchor for the pirouetting motion. Indeed, the results show the expected trend: the rotaxane with the closely coordinating TFA(-) anion pirouettes most slowly, and the most weakly coordinating hexabromoderivative of cobaltabisdicarbollide pirouettes the fastest.

It is envisaged to extend this range also sequentially by changing the metal from cobalt to iron. The last successful synthesis of the highest chlorinated derivatives of cobaltabis(dicarbollide) dates back to 1982, and since then, no more advances have occurred toward more substituted

  Metallacarboranes have been identified as promising pharmacophores and building blocks in drug designed as well as inhibitors of HIV. The aim of this study was to evaluate the putative antimicrobial properties in vitro of cobaltabisdicarbollide [3,3'-Co(1,2-C2B9H11)2](-), H[1], and its derivatives [3,3'-Co(8-R( CH2CH2O)(2)-1,2-C2B9H10)(1',2'-C2B9H11)](-) (R = -OOCCH3 (Na[3]); -OCH3 (Na[6]); -OCH2CH3 (Na[7])). Pure cultures of 16 pathogenic bacterial strains (isolated from animals and humans as well as control strains) and 3 strains of Candida spp. were applied in antimicrobial studies that were performed by the agar-diffusion method of Bauer-Kirby and the method of minimum inhibitory concentrations. The obtained results revealed that among the compounds examined Na[7] and Na[4] exhibited the highest antimicrobial activity that was equal or even higher than those of the commercially available broad-spectrum antibiotic thiamphenicol. The cobaltabisdicarbollide H[1] was shown to express comparatively lower antibacterial and antifungal properties as compared to its derivatives. From a practical point of view it is important to emphasize that the meticillin-resistant strain of Staphylococcus aureus (TSA MRSA), the poliresistant strains of Pseudomonas aeruginosa, as well as of Candida spp., are sensitive to the compounds Na[7] and Na[4].
