A structure-based virtual screening technique was applied to the study of the HCV NS3 helicase, with the aim to find novel inhibitors of the HCV replication. A library of ~450000 commercially available compounds was analysed in silico and 21 structures were selected for biological evaluation in the HCV replicon assay. One hit characterized by a substituted thieno-pyrimidine scaffold was found to inhibit the viral replication with an EC50value in the sub-micromolar range and a good selectivity index. Different series of novel thieno-pyrimidine derivatives were designed and synthesised; several new structures showed antiviral activity in the low or sub-micromolar range.

We recently described a structurally novel series of negative allosteric modulators (NAMs) of the dopamine D2 receptor (D2R) based on thieno[2,3-d]pyrimidine 1, showing it can be structurally simplified to reveal low molecular weight, fragment-like NAMs that retain robust negative cooperativity, such as 3. Herein, we report the synthesis and functional profiling of analogues of 3, placing specific emphasis on examining secondary and tertiary amino substituents at the 4-position, combined with a range of substituents at the 5/6-positions (e.g. aromatic/aliphatic carbocycles). We identify analogues with diverse pharmacology at the D2R including NAMs with sub-μM affinity (9h) and, surprisingly, low efficacy partial agonists (9d and 9i).

In an attempt to discover a new class of antibacterial agents with improved efficacy and to overcome the drug-resistant problems, some novel 4-substituted thieno[2,3-d]pyrimidines have been synthesized via microwave-assisted methodology and evaluated for their in vitro antibacterial activity against various pathogenic bacterial strains. Compounds 12b and 13c showed the promising inhibitory potencies against Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Escherichia coli with MICs ranging from 2 to 10?μg/ml. Compound 13c was also found to be highly potent against methicillin-resistant S. aureus (MRSA) with MIC value of 4?μg/ml. Docking simulation studies have been performed to unravel the mode of action and association study indicate the binding of potent compounds with DHPS enzyme. In silico ADME studies suggest the drug-like characteristics of the potent compounds.
