NMDA receptors are glutamate-gated ion channels (iGluRs) that are involved in several important physiological functions such as neuronal development, synaptic plasticity, learning, and memory. Among iGluRs, NMDA receptors have been perhaps the most actively investigated for their role in chronic neurodegeneration such as Alzheimer's, Parkinson's, and(More)
Here, we report the design of new analogues of spirooxoindolepyrrolidine nucleus as modulators of p53 activity. Compounds (3R,7aR)-6-(4-chlorobenzyl)-1H-spiro[imidazo[1,5-c]thiazole-3,3'-indoline]-2',5,7(6H,7aH)-trione (9c) and (3R,7aR)-5'-methyl-6-(3,4,5-trimethoxybenzyl)-1H-spiro[imidazo[1,5-c]thiazole-3,3'-indoline]-2',5,7(6H,7aH)-trione (10d) are the(More)
The design, synthesis, and antiplasmodial activity of antimalarial heterodimers based on the 1,4-bis(3-aminopropyl)piperazine linker is reported. In this series key structural elements derived from quinoline antimalarials were coupled to fragments capable of coordinating metal ions. Biological evaluation included determination of activity against(More)
Cancer development and chemo-resistance are often due to impaired functioning of the p53 tumor suppressor through genetic mutation or sequestration by other proteins. In glioblastoma multiforme (GBM), p53 availability is frequently reduced because it binds to the Murine Double Minute-2 (MDM2) oncoprotein, which accumulates at high concentrations in tumor(More)
Analogues of the previously described spiro[imidazo[1,5-c]thiazole-3,3'-indoline]-2',5,7(6H,7aH)-trione p53 modulators were prepared to explore new structural requirements at the thiazolidine domain for the antiproliferative activity and p53 modulation. In cell, antiproliferative activity was evaluated against two human tumor cell lines. Derivative(More)
In the attempt to identify a new lead compound able to modify the conformational preferences of the beta-amyloid peptides, a set of new compounds characterized by a thiazolidine ring linked to several different aryl moieties were synthesized. The ability of these compounds to prevent the beta-amyloid aggregation was evaluated using circular dichroism and(More)
A small library of 2,3-dihydroxybenzamide- and N-(2,3-dihydroxyphenyl)-4-sulfonamide-based microsomal prostaglandin E2 synthase-1 (mPGES-1) inhibitors was identified following a step-by-step optimization of small aromatic fragments selected to interact in focused regions in the active site of mPGES-1. During the virtual optimization process, the(More)
Deposition of senile plaques composed of fibrillar aggregates of Abeta-amyloid peptide is a characteristic hallmark of Alzheimer's disease. A widely employed approach in the study of anti-Alzheimer agents involves the identification of substances able to prevent amyloid aggregation, or to disaggregate the amyloid fibrils through a direct structural(More)
PTPRJ is a receptor protein tyrosine phosphatase involved in both physiological and oncogenic pathways. We previously reported that its expression is strongly reduced in the majority of explored cancer cell lines and tumor samples; moreover, its restoration blocks in vitro cancer cell proliferation and in vivo tumor formation. By means of a phage display(More)
CaMKs are a widely distributed family of kinases with multiple and often cell specific effects on intracellular signal transduction pathway. In endothelial cells, it has been recognized a role for CamKII in several pathways such as eNOS activation and nitric oxide production. It is not clear though, whether CaMKII interfere with other endothelial cell(More)
