Porfirinas e terapia fotodinâmica em neoplasias [PDF]
, 2014 As porfirinas demonstraram já as suas potencialidades em vários campos científicos, com principal destaque para aplicações medicinais como a Terapia Fotodinâmica (TFD). Esta terapia emprega a combinação de oxigénio e substâncias ativadas pela luz (fotossensibilizadores) na geração de radicais livres.

Fotokatalitičke oksigenacije organskih supstrata upotrebom metaliranih porfirina
2013U svrhu sinteze novih funkcionaliziranih derivata koji sadrže [3.2.1]-bicikličku strukturu, priređeni su prethodno opisani furanski i tiofenski derivati o-divinilbenzena 15-17. Navedeni spojevi dobiveni su Wittigovom reakcijom u obliku smjese geometrijskih izomera te su dalje podvrgnuti fotokemijskim reakcijama, čime su priređeni furanski i tiofenski ...

Konjugati porfirina i peptida za fotodinamičku terapiju
2017Karcinom je i dalje vodeći uzrok smrti na globalnoj razini, bez obzira na napredak u liječenju i detekciji istih. Konvencionalni kemoterapeutski agensi korišteni u liječenju tumora su nespecifične toksičnosti te osim tumorskih, napadaju i zdrave stanice što dovodi do raznih nuspojava.

Sinteza i supramolekulske interakcije polinorbornanskih bis-porfirina
2015Within the scope of the thesis new bis-porphyrin called "molecular tweezers" has been synthesised, which due to the weak noncovalent interactions acts as a molecular receptor for a variety of organic substrates. "Molecular tweezers" consists of a rigid norbornane bridge that connects porphyrin rings metalated with zinc.

Fotokatalitička oskidacija furo- i tienostilbena upotrebom mangan-porfirina u mikroreaktoru
2021Photochemistry refers to processes in which light, in conjunction with photocatalysts, allows the synthesis of diverse photochemical compounds. The use of porphyrin complexes with specific metals as catalysts yields promising results, and manganese porphyrins, which can be cationic or anionic, are the most widely utilized in diverse chemical processes.
