JAMMING:- 3D Protein analysis

Although several approaches based on physics principles (e.g., electrostatics) have been reported to identify critical residues from the three dimensional structure of proteins (3), there is a limited accessibility to software aimed to identify critical residues from protein structures. Network analysis on the other hand has been recently shown to be succesfull and complementary to protein sequence-based approaches, JAMMING provides a means to identify critical residues from protein 3D structures Efficient identification of critical residues based only on protein structure by network analysis Cusack M, Thibert B, Bredesen DE and del Rio G. 2007.

Libint:- Functions to compute two body integrals

Libint library is used to evaluate the traditional (electron repulsion) and certain novel two-body matrix elements (integrals) over Cartesian Gaussian functions used in modern atomic and molecular theory. The idea of the library is to let computer write optimized code for computing such integrals. There are two primary advantages to this: much less human effort is required to write code for computing new integrals, and code can be optimized specifically for a particular computer architecture (e.g., vector processor).

Libint has been utilized to implement methods such as Hartree-Fock (HF) and Kohn-Sham density functional theory (KS DFT), second-order Moller-Plesset perturbation theory (MP2), coupled cluster singles and doubles (CCSD) method, as well as explicitly correlated R12 methods.
From the compilation notes:-
MacOS X (versions 10.1 and 10.2) seems to set stacksize limit too low for the library generators to run properly. Use unlimit to increase the limit and then proceed with compilation
On Intel Xeon and Pentium4 systems we obtain significantly higher performance with Intel C/C++ compilers. In the latest test we compared Intel C/C++ compiler (version 7.1) against GNU gcc compiler (versions 3.2 and 3.3). libint performs at least 10% better with the former compiler. The recommended compiler options are -O3 -xW -tpp7.

LiBMCS:- Clusters based on maximum common substructure

LibraryMCS clusters a set of chemical structures on a structural basis. Structures that share a common substructure are clustered together. The common substructure is identified by the clustering program, and it is always the largest one among all substructures found in the structure set. Such substructure is called the Maximum Common Substructure (MCS). No predefined fragments are applied in finding the MCS.

Ligand Scout:-

LigandScout is a software tool that allows to rapidly and transparently derive 3D pharmacophores from structural data of macromolecule/ligand complexes in a fully automated and convenient way.

LigBuilder: Build ligands for protein active sites

I recently came across a program called LigBuilder developed at the Molecular Design Laboratory, it is a multiple-purposed program written for structure-based drug design procedure. Based on the three-dimensional structure of the target protein, it can automatically build ligand molecules within the binding pocket and subsequently screen them.

To quote from the website:-

"(1) The program analyzes the binding pocket of the target protein and derives the key interaction sites. A pharmacophore model is suggested and it could be applied to 3D database searching.
(2) User can choose either growing strategy or linking strategy to develop ligand molecules.

(3) Molecules are constructed by using fragments as building blocks. Various kinds of structural manipulation are provided, such as growing, linking, and mutation. On-the-fly minimization of conformation is performed during the building-up procedure. While the target protein is kept rigid, flexibility of the ligand molecules is considered.

(4) Molecules are evolved by Genetic Algorithm. The fitness score of a molecule is evaluated by considering its chemical viability as well as binding affinity.

(5) Chemical rules for judging "drug-likeness" are applied to screen the resultant molecules. Chemical stability, synthesis feasibility, and toxicity can also be taken into account by defining "forbidden structure" libraries.

(6) All the input and output molecules are in popular format, i.e. protein in PDB format and ligand in Sybyl Mol2 format. The program is very easy to use and maintain."

LigBuilder is written in ANSI C++ language and has been tested on UNIX and LINUX but not MacOSX, I've downloaded the siource and with minor modificartions got it to run under MacOSX.

For more detailed description of LigBuilder, please refer to: Wang, R.; Gao, Y.; Lai, L. "LigBuilder: A Multiple-Purpose Program for Structure-Based Drug Design", J.Mol.Model., 2000, 6, 498-516.

Instructions for running LigBuilder under MacOSX.

Download LigBuilder

A folder called LigBuilderv1.2 will be created in 'Downloads' in that folder you should find


bin/ default working directory
pocket/ source codes of POCKET module
grow/ source codes of GROW module
link/ source codes of LINK module
process/ source codes of PROCESS module
parameter/ necessary parameters
example/ test examples
manual/ user manual in HTML
fragment.mdb/ building-block fragment library
forbidden.mdb/ forbidden substructure library
toxicity.mdb/ toxic substructure library

LigBuilder has four main modules, i.e. POCKET, GROW, LINK, and PROCESS. You need to compile them respectively. You can do this by simply entering each subdirectory, i.e. "pocket/", "grow/", "link/", and "process/", and typing "make" to run the Makefile scripts. The scripts will compile the source codes automatically and generate the executable codes. The default C++ compiler assigned in the Makefile script is SGI "CC" compiler. To compile under MacOSX you should open the "MakeFile" in a text editor (i used BBEdit) and modify the first line in the "Makefile" scripts as "CC = g++" before compiling. You need to do this in each of the POCKET, GROW, LINK, and PROCESS folders.

Now open a terminal window and cd to the LigBuilderv1.2 folder

>cd /Downloads/LigBuilderv1.2/

Now cd to each of the POCKET, GROW, LINK, and PROCESS folders in turn and run make and then copy the resulting executable to usr/local/bin, you will need the admin password.

LSD:- Logic for Structure Determination

Logic for Structure Determination (LSD) find all possible molecular structures of an organic compound that are compatible with its spectroscopic data.

Structure building relies on connectivity data found in 2D NMR spectra, without any reference to a chemical shift database. Molecular structures containing up to 50 non-hydrogen atoms were investigated by means of the LSD program.
The measurement protocol that is required by LSD includes the recording of 1D
1H and 13C as well as 2D COSY, HSQC and HMBC spectra. The status of each atom must be defined. It includes the atom symbol, the hybridization state (sp3, sp2 or sp), the number of attached hydrogen atoms, and the electric charge. This part of the data set is most often easily deduced by the user from elementary chemical shift knowledge. The status of the heteroatoms is deduced from the elemental molecular formula.
Carbon-carbon bonds are deduced from COSY and HSQC data while HMBC and HSQC data provide connectivity relationships through one or two bonds for non-hydrogen atom. The constraints imposed by atom status and 2D NMR data may be enforced by other atom neighborhood relationships. For example, it is possible to force a carbon atom to be bound only to carbon atoms. The user is responsible for such supplementary data. Contradictory constraints lead LSD to fail in the search of a solution structure.
The low resolution of HMBC and HSQC spectra in the C-13 chemical shift domain causes peak assignment ambiguities. It is possible to define groups of resonances and to assign a HMBC correlation peak to a group. This means that the correlation is caused by at least one member of the group.
The solutions may be selected using a substructure or a combination of substructures. Those violating Bredt's rule are also discarded.
The input to LSD is coded by the user as a text file, according to the instructions in the MANUAL_ENG.html document.

A program named OUTLSD reads the generated solutions and converts them into various formats: bonds lists, 2D coordinates, fancy 3D coordinates (fancy, due to the lack of stereochemical information), and SMILES chains. The 2D coordinates can be converted to Postscript drawings and to .mol (SDF) files.
Execution of the LSD program may be controlled by specific instructions for output formatting such as: single step execution, search of the biggest found fragment (for debgging purpose), report writing, verbosity level, substructure search.
Tens of structures were investigated by means of the LSD program, essentially in the field of natural product chemistry, and especially for terpenes and alkaloids.

Lumo:- Molecular Orbital Visualisation

Lumo accelerates the visualization of molecular orbitals from electronic structure calculations by harnessing the power of the graphics processing unit in modern macs. Lumo currently reads formatted checkpoint calculations from Gaussian03/09 calculations and there is preliminary support for Orca output files. Lumo was designed to speed up the slow part of looking at molecular orbitals and making molecular orbital diagrams. Lumo eliminates several steps along the process by reading in the output of programs like Gaussian, quickly visualizing the orbitals, and creating pictures of the essential orbitals in seconds.

Lumo requires Mac OS 10.6 or higher, 64-bit processor, and an OpenCL capable compute device. Lumo is routinely run on MacBook Pros and MacBook Airs. For analysis of larger systems, it is recommended to have at least 4GB of system RAM.

There is a movie of Lumo in action on the website

Once there, all the data will be available for comparison, arbitrary calculations like, say : "this list of m/z values should be applied the following mass increase" or "this list of m/z values should be appplied this reaction: -H+Na". The possibilities should be infinite.

Millsian:- Molecular Modeling

Millsian a new approach to molecular modeling

According to Millsian theory, atoms and bonds are made up of discrete surfaces of negative charge, not probability-density clouds. This gives Millsian the ability to calculate and render the exact charge distribution profiles for molecules of any size and complexity.


Further, electrons are localized in molecules to specific regions, i.e. functional groups which act as building blocks, or independent units, in larger structures. Using two basic equations, Millsian has solved the important functional groups of chemistry, allowing molecules of arbitrary size and complexity to be modeled trivially and almost instantly on a personal computer.
To learn about how Millsian translates the underlying theory into a molecular modeling product, please consult the papers:

Molecula Numerica:- Molecular Dynamics

Molecula Numerica is a software categorized in Molecular Dynamics Simulator. The software is produced to give priority to the visualization of the atoms/molecules. You can see what happened in the atomic world in a REAL-TIME sense. Of course the actual time scale of the phenomena in atomic world is pretty small, we mean you can see the computation results in REAL-TIME.
The software simulates not only translating motions but also rotational motions of atoms/molecules. Multi-atom molecules are dealt as a rigid body. So the software has a limitation coming from which High frequency vibration of the bonding is neglected. But the time integration is effectively fast by the simple model. To solve the rotational motion the simulator adopts
quaternion based rotational equation. As for the scheme for time stepping, a Leap-Frog is adopted.

Virtual Grid support is built into Molegro Virtual Docker: for instance, to dock a library of compounds against a receptor, simply setup a compound data source, and select 'start job on Virtual Grid' in the Docking Wizard.
Molegro Virtual Grid is multi-core aware and can be installed on any platform: Linux, Windows, and Mac. The machines in the grid do not need to run the same operating system.

Molecules:- A molecular viewer for the iPhone and iPod Touch

Molecules is an application from Sunset Lake Software for the iPhone and iPod Touch that allows you to view three-dimensional renderings of molecules and manipulate them using your fingers. The molecules can be downloaded from the Protein Data Bank (http://www.rcsb.org/pdb). You can rotate the molecules by moving your finger across the display, zoom in or out by using two-finger pinch gestures, or pan the molecule by moving two fingers across the screen at once. Molecules is free and its source code is available under the BSD license.

MolPro:- Ab initio calculations

Molpro is a complete system of ab initio programs for molecular electronic structure calculations, designed and maintained by H.-J. Werner and P. J. Knowles, and containing contributions from a number of other authors. As distinct from other commonly used quantum chemistry packages, the emphasis is on highly accurate computations, with extensive treatment of the electron correlation problem through the multiconfiguration-reference CI, coupled cluster and associated methods. The recently developed explicitly correlated coupled-cluster methods yield CCSD(T) results with near basis set limit accuracy already with double-ζ or triple-ζ basis sets, thus reducing the computational effort for calculations of this quality by two orders of magnitude. Using local electron correlation methods, which significantly reduce the increase of the computational cost with molecular size, accurate ab initio calculations can be performed for much larger molecules than with most other programs.

Moscito:- simulation software for molecular dynamics (MD) simulation.

Moscito simulation software for molecular dynamics (MD) simulation.
Moscito is designed for condensed phase and gas phase MD simulations of molecular aggregates. Standard molecular mechanics force-fields such as AMBER, OPLS, CHARMM and GROMOS can be employed. Simulations can be carried out in different ensembles such as NVE, NVT or NPT using the weak coupling scheme. (Smooth Particle Mesh) Ewald summation is used for long range electrostatic interactions.

Moscito is quite fast on Intel/AMD architectures since some essential code has been written in assembler.
A parallel version (MPI) of the MD code is part of the distribution.
The distribution comes with a number of tools for setting up and analysing MD simulation runs.
