Computer-Aided Drug Design (CADD)

INQUIRY

As a modern computational technique, CADD technology comprises a broad range of theoretical approaches and in silico methodologies including molecular modeling and design, quantitative structure-activity relationships studies and so on. CADD enables to minimize the synthetic and biological experiments efforts by using modelling techniques and data analysis. In CADD, scientists use designed algorithms to calculate and analyze the relationship between drug molecules and receptor macromolecule to identify and develop a potential lead compound.

Advantages of CADD

  • Compared to HTS, CADD can deliver multiple promising candidates requiring minimal compound.

  • CADD guides the development of huge virtual compound collections and thousands of compounds are allowed be screened at once in a short time.

  • A large number of drug candidates with undesired bioactivity can be filtered by CADD before entering experimental testing, which helps to save research time.

  • CADD provides comprehensive approaches to determine the structure of the receptor and pharmacophore of the ligand, giving rational guidance on the lead design.

  • A diversity of pharmaceutical properties of a potential drug are investigated, supporting the optimization process.

  • Once a functional molecule is determined, it can be grown into a new chemotypes by using CADD and a novel compound can be quickly designed in silico.

  • Development time and costs can be reduced significantly since there's no need of animal and human models.

Our Services

Our computational chemistry team is proficient in diverse disciplines including artificial intelligence, theoretical calculations, cloud computing and biochemistry. BOC Sciences is committed to offer a broad range of CADD services.

Quantum mechanics is applied to determine the structure of proteins and study molecular mechanics. Scientists use this powerful tool to understand the reactions involving proteins with high accuracy and perform the ligand optimization. At BOC Sciences, we provide different and high quality QM calculation services to comprehensively describe the protein system including protein-ligand interactions and structures.

SBVS is an important computational approach widely used in searching for new bioactive molecules against a certain target protein. It covers molecule collections screening, modeling and other computational methodologies. Our teams perform the SBVS by quickly conducting a large-scale searching of compound libraries, docking procedure and finally evaluating their binding affinity.

Unlike SBVS, LBVS dose not use the structural information of a biological target and it conducts the hit searching based on the information of the known ligand. In LBVS, we conduct searching of compounds that are ranked on the basis of similarity to the ligand and deliver compounds exhibiting similar biological properties.

De novo drug design is an efficient method for the discovery of a variety of different biological target classes. It aims to generate new chemical molecules with desired properties in a more time-saving and cost-effective way. At BOC Sciences, we have established both structure-based and ligand-based approaches to accelerate drug discovery process and we are also equipped with a diversity of advanced computational tools and mathematical software.

Absorption, distribution, metabolism and excretion (ADME) properties and various toxicities (T) cover many pharmacokinetic issues that determine whether a drug candidate can interact to target protein and have a effect in human's bodies. Prediction and evaluation of the ADMET are carried out to accelerate the research process and increase the success rate. We perform various assays to investigate parameters including membrane permeability, metabolic stability and toxicity, and we also conduct a rapid and accurate prediction from the structures of the molecule.
