Software for Chemical Structure
Understanding chemical behavior of molecules through chemical structures is an integral part of drug discovery process. However, chemical structure drawing and application of various computational techniques are time-challenging. Siri has capabilities to develop software for chemical structure drawing process. Siri can help you unify various data formats through enhanced database interfaces. We can also develop a number of computational tools that facilitate faster lead identification and optimization.

  • Chemical Nomenclature: Our services help you generate structures from systemic and trivial names, SMILES and Molecular Formula and vise-versa. Siri could also help you handle other data formats with respective to chemical structures.

    Generate Structures from Systemic and Trivial names
    Generate Systematic names from Structures
    Generate SMILES from Structure
    Generate Structure from SMILES
    Generate Structure from Molecular Formula
  • Database Interfaces: Global pharmaceutical R&D would need enhanced database interface to chemical information with access permission controls. This would call for centralized storage, intelligent distribution across the network, unification of various file formats and user friendly interfaces. Siri can help you develop the following solutions:

Structure Drawing/Visualization/Editor: This solution helps you draw chemical structure,import and view structures,  customize visualization and optimize data storage
Chemistry Data Cartridge: This solution helps you build and operate very large databases based on Relational Chemical Gateway data model.This sits between the application APIs and centralized data to enhance your data consistency, accuracy and unify various data formats 
Browser for Chemical Structure Databases: This solution helps you make complex database queries across your global network. This can be empowered with advanced query builder for structures, reactions, generate reports and develop  advanced sorting options and cross database identifier look up

Computational Tools
The attrition in drug development is very high - from several thousand hits identified to a single molecule released into market. The much quoted research facts are that it takes $800 million to bring out a drug to the market after spending 10-12 years. The advent of computational techniques has accelerated drug development at reduced costs. However, Siri recognizes the need to develop custom computational tools to enable faster in-silico screening.

Siri’s custom computational tools are focused on deriving most value out of your combinatorial and traditional chemistry towards lead identification and lead optimization processes. Siri recognizes that the solutions in these processes are most critical to save time and R&D budgets. Siri has identified some of the computational tools that can be custom built to suit the needs of the clients.

Combinatorial Library Enumerator
The need to expand and explore chemistry space, from a prospective scaffold to all possible permutations and combinations with wide range of functional groups attached to it, is very critical. This combinatorial chemical library building is best done by exploiting the power of computational techniques.

Combinatorial Library Enumerator builds all possible structures for a scaffold with desired functional groups. This enables you to build a very large in-silico chemical database in shorter time duration. This chemical database can further be screened to expedite lead identification and lead optimization.

Physico-Chemical Property Calculator
In-silico screening techniques need to be designed to decrease the load on the actual number of wet-lab experiments to be conducted. While Combinatorial Chemical Library Enumerator generates a very large in-silico chemical database, this would need to filtered using multiple criteria. Physico-Chemical property, such as Lipinski, is one of the most used filters and Siri can build a custom computational tool with advanced techniques.

ADME/Toxicity Property Calculator
Most of the hits identified during lead identification/optimization phase get rejected for their unsuitability for human body. However, in-silico screening based on known ADME/Toxicity knowledge base would further decrease the attrition even before virtual screening and synthesis. This would further reduce the load on pre-clinical and clinical trials. With an expert team of chemists and mathematicians, Siri has strong capability to build advanced ADME/Toxicity Property Calculator.

Salt Stripping Tool
In order to analyze pharmacokinetic properties of a parent molecule that binds the target, scientists prefer to understand the chemical behavior with/without salt mixtures. Siri recognizes the need to custom build salt stripping computational tool that can enable faster in-silico screening, modeling and chemical database building.
