Difference between qsar and pharmacophore

-

QSAR (Quantitative Structure-Activity Relationship) and pharmacophore modeling are two different computational techniques used in drug discovery, but they have different focuses and applications.


QSAR is a technique that uses mathematical and statistical models to predict the biological activity or properties of a compound based on its chemical structure and related properties. QSAR models are generated using a set of molecular descriptors, which are numerical representations of a molecule's chemical and physical properties. QSAR models are useful for predicting the activity of compounds and for identifying potential drug candidates.


Pharmacophore modeling, on the other hand, is a technique that focuses on identifying the essential structural and chemical features of a ligand (a molecule that binds to a receptor) that are responsible for its biological activity. The goal of pharmacophore modeling is to generate a three-dimensional (3D) representation of the essential features of a ligand that are responsible for its binding to a target protein or receptor. Pharmacophore models are useful for identifying the key features of a ligand that are necessary for its activity and for designing new compounds that have similar activity.


In summary, QSAR is a technique used to predict the activity of a compound based on its chemical structure and related properties, while pharmacophore modeling is a technique used to identify the key features of a ligand that are necessary for its biological activity. Both techniques are important in drug discovery and development, but they have different focuses and applications.

Calculation of RMSD values between two ligand poses using web servers/tools

-
#Web servers for calculation of RMSD values between a ligand poses.  Please note: One pose should be a reference pose and another should be a query pose. PLDbench:  The RMSD value between two molecules can be calculated using PLDbench. There are four modules in this webserver. Single: This module's functionality is limited to calculating RMSD for the 57 complexes utilized in the benchmarking study. Users must submit the docked pose of a ligand that corresponds to one of the 57 PDB-IDs offered in the drop down option in this module. It accepts three file formats: '.pdb', '.mol2', and '.sdf'. Users can choose the type of RMSD they want to compute. Standard heavy-atom RMSD, Hungarian (symmetry-corrected) heavy-atom RMSD, and Minimum-distance heavy-atom RMSD can all be calculated using this module. As a result, the Hungarian (symmetry-corrected) heavy-atom RMSD value is returned by default.  Link for the server:https://webs.iiitd.edu.in/raghava/pldbench/single.p...

AMBER TUTORIAL-2: How to simulate a protein- ligand system: basic steps for md simulation in amber (AMBER 16)

-
BLOG #3  Hi Guys,           This is a new tutorial on how to simulate a protein-ligand system: basic steps using AMBER. Before we begin, I hope you have read our previous post on AMBER TUTORIAL-1, since I will only be providing additional information with the ligand here, rather than repeating the previous instructions. #To parameterize the ligand file, we start with Antechamber and then parmchck.  These are a series of tools for creating files for organic molecules and some protein metal centers, which can then be read into LEaP. Junmei Wang created the Antechamber suite, which is intended to be used in conjunction with the general AMBER force field (GAFF) (gaff.dat). This is the package's most crucial program. It can convert a variety of files and assign atomic charges and types to them as well. Sqm (or, alternatively, mopac or divcon), atomtype, am1bcc, bondtype, espgen, respgen, and prepgen are among the programs that antechamber runs in respo...

Python script to plot 3D FEL plots

-
Image
  # To plot FEL in 3D use this python script and run as python2.7 fel3d.py. Here the file uses gibbs.txt. therefore before running the script make sure u have the gibbs.txt in the same folder of this script or else provide the location of the script.  I have attached some images from my research article using the same script for 3D FEL plot These plots are published in  Interplay among Structural Stability, Plasticity, and Energetics Determined by Conformational Attuning of Flexible Loops in PD-1 The 2D FEL scripts are also mentioned in the next blog:  Python script to plot 2D FEL Another point to consider is: when u r plotting FEL plots for multiple systems, make sure your color bar/gradient should be same in all the plots. So u can  change the values in vmax,  ax.set_zlim(0, 18),  ticks=range(0, 21, 2)) in the script below.  Like in my case the highest value was 18 in gibbs free energy (the z axis) in all the axis. therefore i mentioned 18 there...
