Structure-Based Virtual Screening (SBVS) Service

Structure-based virtual screening (SBVS) is a computational method used in early drug discovery activities to search compound libraries for new biologically active molecules against specific drug targets. It uses the three-dimensional (3D) structure of the biological target obtained by computational models and other methods to dock a series of chemical compounds to the binding site, and selects a subset of these compounds based on the predicted binding for further biological evaluation.

Overall solutions

• Target design. Often these targets are closely related to a particular disease, and inhibiting or altering these targets will help treat the disease.
• Design and synthesis of a library of compounds containing a variety of small-molecule fragments of drugs. The ideal small molecule fragment should have a certain affinity for the active site of the target, such as the target protein or the targeting enzyme.
• Screening of small synthesized fragments using pre-designed targets.
• According to the results of the screening, molecular fragments with better activity can be obtained, and the lead compounds can be obtained by appropriately combining the fragments.
• The chemical structure of the obtained lead compound is further modified and further optimized to obtain a drug candidate for clinical research.

Structure-based Virtual Screening (SBVS) FAQS

• • Q: What binding site identification methods can be offered?

    • A:

      Static approach: Computational solvent mapping with chemical probes is applied.

      Dynamic approach: The probes and the protein evolve dynamically in time.

      Mixed approach: A chemical probe is used as in the static approach and in addition, the putative binding site is evaluated in terms of flexibility.
  • Q: What are the advantages of SBVS?

    • A: SBVS has the following advantages:

      Reduce the time and cost involved in the screening of millions of small molecules.

      Perform computationally before molecule being synthesized.

  • Q: What is the process of SBVS?

    • A:

      Protein Preparation
      We select and prepare proteins that are closely related to specific diseases.
      Binding site identification

      Compound database preparation
      We designed and synthesized a compound library containing various drug small molecule fragments. The small molecule fragments have an affinity for the active site of the target, such as the target protein or the target enzyme.

      Docking and Scoring
      We screened the synthesized small fragments using various methods such as molecular docking using pre-designed targets.

      Results analysis
      Based on the screening results, molecular fragments with good activity can be obtained, and lead compounds can also be obtained by combining the fragments appropriately.

      Modification and optimization
      The chemical structures of the obtained lead compounds are further modified and optimized to obtain drug candidates for clinical studies.
  • Q: What is the application of SBVS?

    • A:

      Investigate the pathways of interactions (e.g. kinetic of binding, unbinding event)

      Explore binding pockets and/or discover cryptic pockets

      Affinity prediction
  • Q: What are the SBVS service items?

    • A: The basic services of structure-based screening can be summarized as follows:

      Design targeted targets, one or more of these targeted targets will be designed.

      Design and synthesis of a library of compounds containing a variety of small-molecule fragments of drugs. The ideal small molecule fragment should have a certain affinity for the active site of the target, such as the target protein or the targeting enzyme.

      Screening of small fragments of synthesized fragments using pre-designed targeted targets.

      According to the results of the screening, molecular fragments with better activity can be obtained, and the lead compounds can be obtained by appropriately combining the fragments.

      The chemical structure of the lead compound that has been obtained is further modified and further optimized to obtain a drug candidate for clinical research.
