Design, Synthesis and Evaluation of 2,5-Diketopiperazines as Inhibitors of the MDM2-p53 Interaction.
... hydrophobic residues: Phe19, Trp23, and Leu26. Several inhibitors which target the MDM2-p53 interaction have been published . These inhibitors can be divided into three groups: type I, II and III . Type I inhibitors are peptide oligomers designed to mimic the α-helical topography. Type II inhibitors are based on scaffolds that place substituents ... compounds showed no activity. Re-evaluation of the design was therefore performed, aiming for type II inhibitors. Design of type II inhibitors During our studies with type III inhibitors, new crystal structures of MDM2 co-crystallised with highly potent type II inhibitors were published [15,35–37]. Analysis of these as well as previously published crystal ... design, synthesis, and biological evaluation of 2,5-DKP derivatives as potential MDM2-p53 inhibitors. Results and Discussion Design of type III inhibitors It was anticipated that spiro-DKPs (Fig 2A) would be a suitable starting point for the development of novel type III inhibitors, as these shape-programmable scaffolds can project functional groups into
Small molecule inhibitors of the LEDGF site of human immunodeficiency virus integrase identified by fragment screening and structure based design.
... directed IN inhibitors. In conclusion, we have studied the LEDGF binding pocket of HIV IN by using a series of synthetic compounds based on initial hits from a fragment based screen and have identified low micromolar inhibitors based on in vitro biochemical, biophysical and cellular assays. These compounds represent new scaffolds for the design of inhibitors ... containing LEDGF were pooled, dialysed against 25 mM Tris-Cl pH 7.0, 0.5 M NaCl, 5 mM DTT, 5% (v/v) making it a tantalizing target for inhibitors [11,14,18,19]. While our study was underway, several groups reported small molecule inhibitors that bind to this site in HIV IN [8,25–28]. One group used a pharmacophore based on the interactions of the residues ... preventing this step can reduce viral replication and viral load. Current IN inhibitors, such as raltegravir (IsentressTM), bind at the catalytic site of IN and resistance is developed rapidly in the clinic even under optimized HAART . We therefore set out to develop small molecule inhibitors of HIV IN that did not target the catalytic site. Our approach
Selectivity Profiling and Biological Activity of Novel β-Carbolines as Potent and Selective DYRK1 Kinase Inhibitors.

HeLa cells were transiently transfected with a GFP-SF3B1 expression vector and treated with three of the new β-carbolines (AnnH31, AnnH43, AnnH75) in parallel with three established DYRK1A inhibitors (harmine, L41, INDY). Western blot analysis showed that the new inhibitors reduced the phosphorylation ... β-carbolines were examined for selectivity against kinases that are typical targets of other DYRK1A inhibitors, i.e. DYRK1B, DYRK2, HIPK2 and CLK1. Overall, most compounds showed a similar selectivity profile towards these kinases (Fig 1). The more potent DYRK1A inhibitors also inhibited DYRK1B, although slightly less efficiently than DYRK1A.

General amyloid inhibitors? A critical examination of the inhibition of IAPP amyloid formation by inositol stereoisomers.
... and development of islet amyloid inhibitors compared to that invested in studies of Ab inhibitors.

None of the existing IAPP inhibitors have been clinically ... conformational change in IAPP and are ineffective inhibitors of IAPP amyloid formation, although some do lead to modest apparent changes in IAPP amyloid fibril morphology. Thus not all classes of Ab inhibitors are effective against IAPP. This work provides a basis of comparison to work on polyphenol based inhibitors of IAPP amyloid formation and helps ... states and share some common characteristics. Comparatively little effort has been expended on the design of IAPP amyloid inhibitors, thus it is natural to inquire if Ab inhibitors are effective against IAPP, especially since no IAPP inhibitors have been clinically approved.

Cyclophilin inhibitors (CypI) represent the most advanced HTAs in the treatment of HCV-infected patients. The CypI, alisporivir (ALV), provided high efficacy as HTA treatment with or without IFN in phase II and III studies [8–10]. IFN-free ALV treatment is highly effective in GT2 and 3 patients . This is significant since NS3i, NS5Ai and NS5Bi inhibitors
