Pharmacophore-based Virtual Screening
Pharmacophore-based virtual screening is a powerful tool in the field of computer-aided drug design (CADD). It enables the identification and selection of potential drug candidates from large chemical libraries based on the common features and spatial arrangements of molecules that interact with a target receptor. At CD ComputaBio, we offer state-of-the-art pharmacophore-based virtual screening services to accelerate the drug discovery process.
Introduction to Pharmacophore-based Virtual Screening
Pharmacophore-based virtual screening is a computational technique centered on the concept of pharmacophores—the abstract representations of molecular features that are necessary for a compound to interact with a specific biological target. This methodology is distinctly advantageous in drug design, as it allows researchers to prioritize and screen large compound libraries without the need for extensive experimental validation in the early phases of research.

Our Service
Pharmacophore Model Development
Our team creates robust pharmacophore models tailored to specific target proteins, integrating data from existing ligands, receptor structures, and biological activity profiles. This foundational service sets the stage for successful virtual screening.
Large-Scale Virtual Screening
We offer comprehensive virtual screening against extensive compound libraries. Utilizing our proprietary algorithms, we ensure accurate identification of lead candidates that align with your pharmacophore model, enhancing hit selection efficiency.
Hit Identification and Validation
Following virtual screening, we perform extensive analysis to identify and validate hits. This process incorporates molecular docking studies and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) profiling to assess the drug-likeness of candidates.
Lead Optimization
Once promising candidates are identified, our lead optimization service provides iterative cycles of design, synthesis, and testing, improving compound efficacy and safety profiles through computational predictions and empirical validation.
The Processes of Bioavailability Assessment of PROTAC
Target Definition and Analysis - We start by understanding the properties and requirements of your drug target, including its structure, function, and known ligands.
01
Pharmacophore Hypothesis Generation - Based on the target analysis, we propose a pharmacophore hypothesis that captures the essential features for ligand binding.
02
Hit Selection and Ranking - The identified hits are ranked based on their fit to the pharmacophore and other relevant properties such as druglikeness and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) predictions.

Approaches to Pharmacophore-Based Virtual Screening
Ligand-Based Virtual Screening
This approach focuses on the characteristics of known active compounds. By analyzing their structures, we can derive a pharmacophore model that highlights essential features.
Structure-Based Virtual Screening
In this method, we utilize crystal structures of target proteins to design pharmacophore models based on the binding dynamics observed in the active sites.
Hybrid Virtual Screening
Combining both ligand- and structure-based methods, our hybrid approach offers superior results by utilizing all available data, thereby increasing the likelihood of discovering novel lead compounds.
