Photoantibacterial Poly(vinyl)chloride Films Applying Curcumin Derivatives as B...

Rodrigues, Fábio M. S.; Tavares, Iúri; Aroso, Rafael T.; Dias, Lucas D.; Domingos, Carolina V.; de Faria, Clara M. G.; Piccirillo, Giusi

Herein we describe the design of natural curcumin ester and ether derivatives and their application as potential bioplasticizers, to prepare photosensitive phthalate-free PVC-based materials. The preparation of PVC-based films incorporating several loadings of newly synthesized curcumin derivatives along with their standard solid-state characterization is also described. Remarkably, the plasticizing effect of t...


Carbon Monoxide as C1 Building Block in Fine Chemical Synthesis†

Carrilho, Rui M. B.; Calvete, Mário J. F.; Mikle, Gábor; Kollár, László; Pereira, Mariette M.

Carbon monoxide (CO) has become one of the most relevant and versatile renewable C1 building blocks for chemical synthesis, e s- pecially in the fine chemicals industry, due to the development of efficient and selective catalysts for its activation. In t his review, we present a c omprehensive critical analysis of the last 10 years literature on the use of CO as a renewable feedstock for fine chemicals producti...



Stereoisomeric Tris-BINOL-Menthol Bulky Monophosphites: Synthesis, Characterisa...

Felgueiras, Alexandre P.; Rodrigues, Fábio M. S.; Carrilho, Rui M. B.; Cruz, Pedro F.; Rodrigues, Vítor H.; Kégl, Tamás; Kollár, László

Four stereoisomeric monoether derivatives, based on axially chiral (R)- or (S)-BINOL bearing a chiral (+)- or (-)-neomenthyloxy group were synthesised and fully characterised by NMR spectroscopy and X-ray crystallography. The respective tris-monophosphites were thereof prepared and fully characterised. The coordination ability of the new bulky phosphites with Rh(CO)2(acac), was attested by 31P NMR, which presen...


Synthesis of Computationally Designed 2,5(6)-Benzimidazole Derivatives via Pd-C...

Aroso, Rafael T.; Guedes, Rita C.; Pereira, Mariette M.

A pharmacophore model for inhibitors of Escherichia coli's DNA Gyrase B was developed, using computer-aided drug design. Subsequently, docking studies showed that 2,5(6)-substituted benzimidazole derivatives are promising molecules, as they possess key hydrogen bond donor/acceptor groups for an efficient interaction with this bacterial target. Furthermore, 5(6)-bromo-2-(2-nitrophenyl)-1H-benzimidazole, selected...


Transport and photophysical studies on porphyrin-containing sulfonated poly(eth...

Sousa, Joana F. M.; Pina, João; Gomes, Carla; Dias, Lucas D.; Pereira, Mariette M.; Murtinho, Dina; Dias, Paula; Azevedo, João; Mendes, Adélio

The development of efficient and reliable membranes for redox flow batteries (RFBs) with high ionic conductivity and selectivity is challenging. Aiming the development of better membranes, we have synthesized porphyrin-containing sulfonated poly(etheretherketone) (SPEEK). In particular, the effect of water soluble 5,10,15,20-tetrakis(N-methyl-4-pyridinyl)porphyrin iodide (TMePyPI4) and its Cu(II) complex, 5,10,...


Immobilization of Rh(I)-N-Xantphos and Fe(II)-C-Scorpionate onto Magnetic Nanop...

Rodrigues, Fábio M. S.; Dias, Lucas D.; Calvete, Mário; Maria, Teresa M. R.; Rossi, Liane M.; Pombeiro, Armando J. L.; Martins, Luísa M. D. R. S.

Two heterogeneous catalysts, MNP@SiO2-N-Xantphos/Rh(I) and MNP@SiO2-NH-Cscorpionate/ Fe(II), were prepared by reaction of chloro-functionalized MNP@SiO2 with N-Xantphos and amino-functionalized MNP@SiO2 with iron(II)/C-allyl-scorpionate through nucleophilic substitution and hydroaminomethylation reactions, respectively. All catalysts were characterized using standard spectroscopic means, transmission electron m...


Oxidative Degradation of Pharmaceuticals: The Role of Tetrapyrrole-Based Catalysts

Piccirillo, Giusi; Aroso, Rafael T.; Rodrigues, Fábio M.S.; Carrilho, Rui M. B.; Pinto, Sara M. A.; Calvete, Mário J. F.; Pereira, Mariette M.

Nowadays, society’s widespread consumption of pharmaceutical drugs and the consequent accumulation of such compounds or their metabolites in effluents requires the development of efficient strategies and systems that lead to their effective degradation. This can be done through oxidative processes, in which tetrapyrrolic macrocycles (porphyrins, phthalocyanines) deserve special attention since they are among th...


Advances in the automated synthesis of 6-[18F]Fluoro-L-DOPA

Neves, Ângela C. B.; Hrynchak, Ivanna; Fonseca, Inês; Alves, Vítor H. P.; Pereira, Mariette M.; Falcão, Amílcar; Abrunhosa, Antero J.

The neurotracer 6-[18F] FDOPA has been, for many years, a powerful tool in PET imaging of neuropsychiatric diseases, movement disorders and brain malignancies. More recently, it also demonstrated good results in the diagnosis of other malignancies such as neuroendocrine tumours, pheochromocytoma or pancreatic adenocarcinoma.The multiple clinical applications of this tracer fostered a very strong interest in the...
