We have investigated the effect of dexamethasone (DEX) on the apoptosis induced by TRAIL (tumour necrosis factor-related apoptosis inducing ligand) in follicular undifferentiated thyroid (FRO) cancer cells. Apoptosis was measured by percent hypodiploid nuclei, caspase-3 and -8 activation, and mitochondrial membrane depolarisation. DEX nearly abolished(More)
We investigated the expression of annexin-1 (ANXA1) in thyroid carcinoma cell lines and in thyroid cancers with a different degree of differentiation. The highest level of ANXA1 expression examined by Western blotting was detected in the papillary carcinoma cells (NPA) and in the follicular cells (WRO). On the other hand, the most undifferentiated thyroid(More)
Five new 14,15-secopregnane derivatives, named argelosides K-O (1-5), have been isolated from Solenostemma argel leaves. Their structures were established by a detailed spectroscopic analysis. In particular, argeloside N (1) showed in the sugar portion an unusual 3-O-methyl-2,6-dideoxyhexopyranose unit characterized by the occurrence of a Delta3 double(More)
In this work, the production of dexametasone and dexametasone acetate microparticles is proposed using supercritical-assisted atomization (SAA). This process is based on the solubilization of supercritical carbon dioxide in a liquid solution containing the drug; then, the ternary mixture is sprayed through a nozzle and submicroparticles are formed as a(More)
As a part of our drug discovery efforts we developed a series of simplified derivatives of bolinaquinone (BLQ), a hydroxyquinone marine metabolite, showing potent anti-inflammatory activity. Thirteen new hydroxyquinone derivatives closely related to BLQ were synthesized and tested on mouse macrophage-like RAW 264.7 cell line in order to investigate their(More)
Annexin-1 (ANXA1, lipocortin-1) is the first characterized member of the annexin superfamily of proteins, so called since their main property is to bind (i.e. to annex) to cellular membranes in a Ca2þ -dependent manner. Originally described as a phospholipase A2-inhibitory protein, ANXA1 can affect many components of the inflammatory reaction besides the(More)
