Abstract: Aim: LK (B-lymphocyte kinase) is a protein from the family SRC (Proto-oncogene tyrosine-protein kinase), an important cell signaling molecule that influences cellular response. The BLK kinase has been potential target for cancer therapy. As result, this could be initial step toward development of novel inhibitors to fight cancer. Materials and Methods: A homology model human tyrosine ...

The dopamine 3 (D3) receptor is a promising therapeutic target for the treatment of nervous system disorders, such as Parkinson's disease, and current research interests primarily focus on the discovery/design of potent D3 agonists. Herein, a well-designed computational protocol, which combines pharmacophore identification, homology modeling, molecular docking, and molecular dynamics (MD) simul...

Cdc2-like kinase 4 (Clk4) and dual specificity tyrosine-phosphorylation-regulated kinase 1A (Dyrk1A) are protein kinases that are promising targets for treatment of diseases caused by abnormal gene splicing. 6-Arylquinazolin-4-amines have been recently identified as potent Clk4 and Dyrk1A inhibitors. In order to understand the structure-activity correlation of these analogs, we have applied lig...

The computational modeling and high throughput screening techniques have been used to identify small molecules that specifically target functional surface sites of the androgen receptor in Prostate cancer. Pharmacophore modeling, Virtual screening, docking based analyses is used for development of new chemical entities. The purpose of the current work is to establish pharmacophore model for the...

A detection of the three-dimensional binding mode between a protein and a chemical compound is valuable to optimize drug candidates for high-throughput screening. Pharmacophore models are essential functional groups of atoms in the proper three-dimensional position to interact with a given receptor, and widely used for drug design. Recent pharmacophore models can be classified into two categori...

In an effort to develop a quantitative ligand-binding model for the receptor tyrosine kinases, a pharmacophore search was first used to identify structural features that are common in two novel sets of 12 molecules of the 3-substituted indolin-2-ones and 19 compounds of the benzylidene malononitriles with low-to-high affinity for HER2, a kind of receptor tyrosine kinase. The common pharmacophor...

A combined ligand and structure-based drug design approach provides a synergistic advantage over either methods performed individually. Present work bestows a good assembly of ligand and structure-based pharmacophore generation concept. Ligand-oriented study was accomplished by employing the HypoGen module of Catalyst in which we have translated the experimental findings into 3-D pharmacophore ...
