Part-III Drug designing softwares
INTRODUCTION
Drug discovery and designing is an expensive process due to the high costs of R&D and human
clinical tests. The average total cost per drug development varies from US$ 897 million to US$
1.9 billion. The typical development time is 10-15 years. R&D of a new drug involves the
identification of a target (e.g. protein) and the discovery of some suitable drug candidates that
can block or activate the target. Clinical testing is the most extensive and expensive phase in
drug development and is done in order to obtain the necessary governmental approvals. In the
US drugs must be approved by the Food and Drug Administration (FDA).Computer aided drug
design CADD or the Computer assisted drug design or the Computer assisted Molecular-
designing CAMD involve all the computer-assisted techniques used to design, discover and
optimize biologically active compounds. CADD contributes not only to the design of potential
compounds but also to many of the steps of going from an “Idea to Drug”. It helps in finding out
new leads and also optimizing them. The recent advances in CADD are now finding out the
ligands that will interact with the receptor that is present at the target site or the site of action.
Binding of a ligand to the receptor involves various types of interactions like the hydrophobic,
electrostatic and hydrogen bonding interactions. Additionally, solvation energies of the ligand
and receptor site are also important because for the binding to take place, partial to complete
deslovation of the molecule is necessary. This approach to CADD optimizes the fit of a ligand in
a receptor site. The approach of CADD is dependent on the quantity of data that is available on
the ligand and the receptor. Three-dimensional structural information of the receptor and the
receptor ligand complex are obtained from techniques like the X-Ray Diffraction studies and
NMR spectral analysis. Drug design is a process which involves the identification of a
compound that displays a biological profile and ends when the biological profile and chemical
synthesis of the new chemical entity are optimized. Drug designing is otherwise known as
rational drug design and it is a method of finding new medications based on the biological
receptors and target molecules. It involves the designing of small molecules which is
complementary to the biological receptor to which they bind and interact to cause the
pharmacological actions. Computer aided drug design CADD or the Computer assisted drug
, Design or the Computer assisted Molecular-designing CAMD involve all the computer-assisted
techniques used to design, discover and optimize biologically active compounds.
DRUG DESIGNING SOFTWARES
A computer needs software for its functions such as programs. This software makes our work
simpler and faster. Various companies such as Accelrys, Schrodinger, Auto Dock and Argus Lab
offering drug designing softwares.
Accelrys
Accelrys is a software company with its headquarters in US, along with its organization in
Europe and Japan. It provides softwares especially for drug discovery and materials science.
Their products and technologies create solutions for several stages in the drug discovery and
developmental process. The different softwares produced by Accelrys are:
• Insight II
• Pipeline Pilot
• Discovery Studio
• Materials Studio
• Accord
Insight II
Insight II is a graphical molecular modeling program. Using this software we can build and
manipulate virtually any class of molecules or molecular systems. Some of these insight II
computational engines have the capacity to restart calculations from informations in the saved
files.
Pipeline Pilot
Pipeline Pilot datas are based on powerful client server platform that leads to construct graphical
workflows for data retrieval, filtering, analysis, and re-porting. Data modeling in this software is
done by modeling tools, statistical filters and clustering components optimized for large real-
world data sets. One can create additional components using various technologies such as Perl,
Java, SOAP and basic command line access. This software is used for sequence analysis, gene
