Pharmaceutical patents and the right to access to medicines in Central America
2020
El vínculo entre la propiedad intelectual y el derecho a la salud se ha convertido en un tema de debate central desde la conferencia ministerial de la Organización Mundial del Comercio (OMC) en 2001. En efecto, a pesar del amplio reconocimiento del derecho a la salud en la escena internacional, la cuestión de la protección efectiva y la aplicación del derecho en cuestión es tema de un debate constante. El objetivo de las patentes farmacéuticas, es proporcionar al inventor un conjunto de derechos exclusivos durante un período de tiempo determinado a cambio de la divulgación pública del medicamento recién protegido. El régimen de monopolio establecido conduce a un aumento significativo de los…
Novel 1H‑Pyrrolo[2,3‑b]pyridine Derivative Nortopsentin Analogues: Synthesis and Antitumor Activity in Peritoneal Mesothelioma Experimental Models
2013
In this study, we describe the synthesis of new nortopsentin analogues, 1H-pyrrolo[2,3-b]pyridine derivatives and their biological effects in experimental models of diffuse malignant peritoneal mesothelioma (DMPM), a rare and rapidly fatal disease, poorly responsive to conventional therapies. The three most active compounds, 1f (3-[2-(5-fluoro-1-methyl-1H-indol-3- yl)-1,3-thiazol-4-yl]-1H-pyrrolo[2,3-b]pyridine), 3f (3-[2-(1H-indol-3-yl)-1,3- thiazol-4-yl]-1-methyl-1H-pyrrolo[2,3-b]pyridine), and 1l (3-[2-(5-fluoro-1- methyl-1H-indol-3-yl)-1,3-thiazol-4-yl]-1-methyl-1H-pyrrolo[2,3-b] pyridine), which were shown to act as cyclin-dependent kinase 1 inhibitors, consistently reduced DMPM cell p…
SYNTHESIS AND BIOLOGICAL EVALUATION OF NOVEL SMALL MOLECULES AS PROMISING ALTERNATIVE AGENTS TO COUNTERACT DRUG RESISTANCE IN CANCER AND MICROBIAL IN…

Il cancro rimane un grave problema di salute pubblica, rappresentando la seconda principale causa di morte in tutto il mondo. Tra le diverse tipologie di tumori, l'adenocarcinoma duttale pancreatico (PDAC) è una delle forme più letali nell'uomo, a causa della diagnosi tardiva e delle limitate possibilità di trattamento. Pertanto, lo studio di nuove strategie terapeutiche per i pazienti affetti da PDAC è altamente necessario. Allo stesso modo, il mesotelioma rappresenta una malattia rara ma aggressiva, difficile da diagnosticare per il lungo periodo di latenza prima dei segni clinici. Gli approcci terapeutici standard includono la chirurgia, la chemioterapia e la radioterapia. Tuttavia, la s…

Studio del ruolo delle mutazioni “gatekeeper” V654A e T670I di c-kit kinase nell’interazione con inibitori attraverso un approccio misto Dinamica Mol…

La sovraespressione del proto-oncogene c-kit è stata riscontrata nelle cellule ematopoietiche, nel cancro a piccole cellule del polmone e nei tumori stromali gastrointestinali1-3. L’importanza clinica dell’espressione di c-kit nei tumori ha indirizzato la ricerca verso inibitori di questa tirosina chinasi. Imatinib (Gleevec®) (in figura) è stato il primo farmaco utilizzato in terapia, ma la comparsa di mutazioni su c-kit ha portato ad una riduzione dell’efficacia o a completa resistenza a questo trattamento. In alternativa, altri composti si sono mostrati attivi anche nei confronti dei mutanti come ad esempio Sunitinib (Sutent®)4, ma la necessità di nuovi e più efficaci inibitori contro i m…
4,5,6,9-TETRAHYDROPYRROLO[2',3'-3,4]CYCLOEPTA[1,2-d]ISOSSAZOLE, PROCESS FOR THEIR PRODUCTION AND THEIR USES AS ANTITUMOR AGENTS
2016
The present invention concerns the synthesis of compounds bearing the PYRROLO[2',3'-3,4]CYCLOEPTA[1,2-d]ISOSSAZOLE structure, and their use for the treatment of pathologies having hyperproliferative features included those having neoplastic nature.
Hand-made paper obtained by green procedure of cladode waste of Opuntia ficus indica (L.) Mill. from Sicily
2019
Cellulosic fibres have been obtained by green procedures from the cladodes of Opuntia ficus indica (L.) Mill., constituting a large agro industrial waste in our territory. The materials have been analysed for its relative composition, applying, IR and TG methodologies and it was characterised by the absence of lignin. The fibrous material allowed the manufacture of a handmade paper obtaining an ecological material suitable for packaging purposes. The authors evidenced that the simple protocol based on hot water treatment was able to decrease the amount of hemicellulose in the final material.
The new iodoacetamidobenzofuran derivative TR120 decreases STAT5 expression and induces antitumor effects in imatinib-sensitive and imatinib-resistan…

The identification of novel compounds modulating the expression/activity of molecular targets downstream to BCR-ABL could be a new approach in the treatment of chronic myeloid leukemias (CMLs) resistant to imatinib or other BCR-ABL-targeted molecules. Recently, we synthesized a new class of substituted 2-(3,4,5-trimethoxybenzoyl)-2-N,N-dimethylamino-benzo[b]furans, and among these 3-iodoacetylamino-6-methoxybenzofuran-2-yl(3,5-trimethoxyphenyl)methanone (TR120) showed marked cytotoxic activity in BCR-ABL-expressing cells. Interestingly, TR120 was more potent than imatinib in cell growth inhibition and apoptosis induction in both BCR-ABL-expressing K562 and KCL22 cells. Moreover, it showed a…
