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)
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.
Activation of the Smoothened (Smo) receptor mediates Hedgehog (Hh) signaling. Hh inhibitors are in clinical trials for cancer, and small-molecule Smo agonists may have therapeutic interests in regenerative medicine. Here, we have generated and validated a pharmacophoric model for Smo agonists and used this model for the virtual screening of a library of(More)
The two members of the LIM domain kinase family (LIMK1 and LIMK2) represent crucial keys in the signaling pathways that modulate the structure and activity of actin cytoskeleton. They maintain the optimal balance between phosphorylated and unphosphorylated cofilin that in turn acts by severing filamentous actin into globular actin and ensures actin turnover(More)
A hit optimization protocol applied to the first nonnucleoside inhibitor of the ATPase activity of human DEAD-box RNA helicase DDX3 led to the design and synthesis of second-generation rhodanine derivatives with better inhibitory activity toward cellular DDX3 and HIV-1 replication. Additional DDX3 inhibitors were identified among triazine compounds.(More)
The 1,5-diarylpyrrole derivative BM212 was previously shown to be active against multidrug-resistant clinical isolates and Mycobacterium tuberculosis residing within macrophages as well as against Mycobacterium avium and other atypical mycobacteria. To determine its mechanism of action, we identified the cellular target. Spontaneous Mycobacterium smegmatis,(More)
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)
