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)
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)
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)
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)
It is well known that resveratrol (RSV) displayed cancer-preventing and anticancer properties but its clinical application is limited because of a low bioavailability and a rapid clearance from the circulation. Aim of this work was to synthesize pharmacologically active resveratrol analogs with an enhanced structural rigidity and bioavailability. In(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)
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)
Analogs of potent CaMKinase II inhibitor, CaM-KNtide, were prepared to explore new structural requirements for the inhibitory activity. The full potency of CaMKII inhibition by CaM-KIINα is contained within a minimal region of 19 amino acids. Here, analysis of the homologous CaM-KIINβ showed that a 17 mer peptide (CN17β) was the shortest sequence that still(More)
