Synthetic scorpiand-like azamacrocycles selectively inhibit SOD and TR enzymes of Trypanosoma cruzi in mice causing death of the parasites and increasing the mouse survival rate after infection and treatment.

the same conditions. An evenly distribution of catalytic centres was obtained on the MWCNTs surface. Catalytic properties of these materials were assessed toward the Cu-free Sonogashira cross-coupling, leading to significant improvements in terms of yields and reactionconditions, especially when considering the possibility to maintain yields of 90%, or above, in a feasible amount of time (2 h), while
The detection of nucleotides is of crucial importance because they are the basic building blocks of nucleic acids. Scorpiand‐based polyamine receptors functionalized with pyridine or anthracene units are able to form stable complexes with nucleotides in water, based on coulombic, π–π stacking, and hydrogen‐bonding interactions. This behavior has been rationalized by means of an exploration with NMR
DNA interaction with scorpiand azamacrocycles has been achieved through modulation of their binding affinities. Studies performed with different experimental techniques provided evidence that pH or metal-driven molecular reorganizations of these ligands regulate their ability to interact with calf thymus DNA (ctDNA) through an intercalative mode. Interestingly enough, metal-driven molecular reorganizations serve to increase or decrease the biological activities of these compounds significantly.

Compuestos macrocíclicos de tipo escorpiando y su uso como antiparasitarios. La presente invención hace referencia a compuestos macrocíclicos de tipo escorpiando, los cuales adquieren dicha nomenclatura debido a la particular forma de su estructura química formada por un cuerpo macrocíclico y un brazo colgante donde pueden sustituirse diferentes radicales. La presente invención además comprende el uso de dichos compuestos como medicamentos, particularmente en el tratamiento de enfermedades causadas por parásitos, preferentemente por los parásitos Trypanosoma cruzi o Leishmania spp, como por ejemplo la enfermedad de Chagas o la Leishmaniasis.
