HIV-1 reverse transcriptase (RT) inhibitors currently used in antiretroviral therapy can be divided into two classes: (i) nucleoside analog RT inhibitors (NRTIs), which compete with natural nucleoside substrates and act as terminators of proviral DNA synthesis, and (ii) non-nucleoside RT inhibitors (NNRTIs), which bind to a hydrophobic pocket close to the(More)
Targeting cellular cofactors instead of viral enzymes represents a new strategy to combat infectious diseases, which should help to overcome the problem of viral resistance. Recently, it has been revealed that the cellular ATPase/RNA helicase X-linked DEAD-box polypeptide 3 (DDX3) is an essential host factor for the replication of several viruses such as(More)
A structure-based molecular modeling approach was performed to identify novel structural characteristics and scaffolds that might represent new classes of HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs). The software LigandScout was used for identification and visualization of protein-ligand interaction sites and pharmacophore model(More)
BACKGROUND The non-receptor tyrosine kinases c-Abl and c-Src are overexpressed in various solid human tumours. Inhibition of their hyperactivity represents a molecular rationale in the combat of cancerous diseases. Here we examined the effects of a new family of pyrazolo [3,4-d] pyrimidines on a panel of 11 different murine lung tumour progenitor cell(More)
