The poor prognosis of Glioblastoma Multiforme (GBM) is due to a high resistance to conventional treatments and to the presence of a subpopulation of glioma stem cells (GSCs). Combination therapies targeting survival/self-renewal signals of GBM and GSCs are emerging as useful tools to improve GBM treatment. In this context, the hyperactivated AKT/mammalian(More)
Aggressive behavior and diffuse infiltrative growth are the main features of Glioblastoma multiforme (GBM), together with the high degree of resistance and recurrence. Evidence indicate that GBM-derived stem cells (GSCs), endowed with unlimited proliferative potential, play a critical role in tumor development and maintenance. Among the many signaling(More)
A small library of arylthioamides 1-12 was easily synthesized, and their H2S-releasing properties were evaluated both in the absence or in the presence of an organic thiol such as l-cysteine. A number of arylthioamides (1-3 and 7) showed a slow and l-cysteine-dependent H2S-releasing mechanism, similar to that exhibited by the reference slow H2S-releasing(More)
Starting from the previously developed P-gp ligands 1a and 1b (EC₅₀ = 0.25 μM and 0.65 μM, respectively), new arylmethyloxyphenyl derivatives have been synthesized as P-gp modulators in order to investigate: (i) the effect of small electron-donor groups (OMe) (5-11), (ii) the effect of the replacement of methoxy groups with an electron-withdrawal(More)
A series of rivastigmine-caffeic acid and rivastigmine-ferulic acid hybrids were designed, synthesized, and evaluated as multifunctional agents for Alzheimer's disease (AD) in vitro. The new compounds exerted antioxidant neuroprotective properties and good cholinesterases (ChE) inhibitory activities. Some of them also inhibited amyloid protein (Aβ)(More)
This study was aimed at investigating the antitumor activity of novel 2-oxindole derivatives against a well-characterized human nonsmall cell lung cancer (NSCLC) cell line. Test compounds produced an antiproliferative activity in the low micromolar/submicromolar range of concentrations and significantly induced typical apoptotic morphology with cell(More)
Alzheimer diseases (AD) is a multifactorial pathology characterized by a complex etiology. The hallmarks of AD, such as Aβ deposits in senile plaque and neurofibrillary tangles (NFT), are strongly intertwined with reactive oxygen species (ROS)production and oxidative stress (OS),which are considered the common effectors of the cascade of degenerative(More)
The infections caused by Group B Streptococci (GBS) are particularly serious in newborns. Colonized mothers are responsible for the infection's transmission at delivery. The aim of our work has been to estimate the number of carriers of GBS among women recovered at the Hospital of Pistoia.
