Microtubule-stabilising agents laulimalide and peloruside have been compared with tubulin-interacting drugs paclitaxel and colchicine by different computational approaches. Docking and QSAR-based programs point to a favourable interaction with the beta tubulin paclitaxel binding site, although an additional, preferred binding site has been found at the(More)
Fibroblast growth factors (FGFs) are members of a family of polypeptides synthesized by a variety of cell types during the processes of embryonic development and in adult tissues. FGFs have been detected in normal and malignant cells and show a biological profile that includes mitogenic and angiogenic activity with a consequent crucial role in cell(More)
Maize polyamine oxidase (MPAO), the only member of the polyamine oxidase (PAO) family whose three-dimensional structure is known, is characterized by a 30 A long U-shaped catalytic tunnel located between the substrate binding domain and the FAD. To shed light on the MPAO ligand binding mode, we studied the inhibition properties of linear diamines, agmatine,(More)
Compounds currently used for the treatment of HIV-1 Infections are targeted to viral proteins. However, the high intrinsic mutation and replication rates of HIV-1 often lead to the emergence of drug resistant strains and consequent therapeutic failure. On this basis, cellular cofactors represent attractive new targets for HIV-1 chemotherapy, since targeting(More)
A series of new pyridazin-3(2H)-one derivatives (3 and 4) were evaluated for their in vitro affinity toward both alpha(1)- and alpha(2)-adrenoceptors by radioligand receptor binding assays. All target compounds showed good affinities for the alpha(1)-adrenoceptor, with K(i) values in the low nanomolar range. The polymethylene chain constituting the spacer(More)
Nonnucleoside reverse transcriptase inhibitors (NNRTIs) have, in addition to the nucleoside reverse transcriptase inhibitors (NRTIs) and protease inhibitors (PIs), a definitive role in the treatment of HIV-1 infections. Since the appearance of HEPT and TIBO, more than 30 structurally different classes of compounds have been reported as NNRTIs, which are(More)
The LIM kinases 1 and 2 (LIMK1 and LIMK2) are dual specificity (serine/threonine and tyrosine) kinases. Although they show significant structural similarity, LIMK1 and LIMK2 show different expression, subcellular localization, and functions. They are involved in many cellular functions, such as migration, cycle, and neuronal differentiation and also have a(More)
An in silico structure-based ligand design approach resulted in the identification of the first non-peptidic small molecule able to inhibit protein-protein interactions between 14-3-3 and c-Abl. This compound shows an anti-proliferative effect on human leukemia cells either sensitive or resistant to Imatinib, in consequence of the T315I mutation. It also(More)
Novel 1,4,6-trisubstituted pyrazolo[3,4-d]pyrimidines are reported with preliminary in vitro activity data indicating that several of them are potent inhibitors (better than the reference compound) of Src phosphorylation of the breast cancer cells 8701-BC, known to overexpress Src. The ability of such compounds to significantly reduce 8701-BC cell(More)
A series of novel enantiomerically pure azole derivatives was synthesized. The new compounds, bearing both an imidazole as well as a triazole moiety, were evaluated as antimycobacterial agents. One of them proved to have activity against Mycobaterium tuberculosis comparable to those of the classical antibacterial/antifungal drugs Econazole and Clotrimazole.
