    CDD Vault Update (February 2024): New Models for LogD and LogP, Similarity Scores in Deep Learning, and Updated GET Users Call

    New LogP and LogD Models

    The models used for calculating the LogP and LogD scores based on the chemical structures registered in a Vault have been updated with an extended set of training data. The values for LogP and LogD in CDD Vault might change based on these updated models. (For example, the dataset used in the new LogD models was increased considerably by incorporating data aggregated from ChEMBL by Wang et al. (2023, ChEMBL) and by reviewing and adding new data from PubChem. Additional effort was made to add logD values for peptides.)

    Similarity Scores in Deep Learning Search Results 

    CDD’s proprietary machine learning technology can rapidly search ChEMBL to suggest similar chemical structures for the compounds registered in your proprietary Vault. The Deep Learning algorithm now reports a similarity score for each ChEMBL compound returned. The score will appear below each structure (complete with a hover pop-up description) and is included in the exported file.

    Read more about the Deep Learning feature set in this Release Note, and/or watch a recording of a webinar showcasing this technology.

    Email Addresses in GET Users

    Email addresses are now included in the GET Users API call. Remember, for security purposes, this API command is only available for Vault Administrators.

    The JSON returned now includes a section resembling this:

            "id": 1234,
            "first_name": "Charlie",
            "last_name": "Weatherall",
            "email": "charlie@collaborativedrug.com",
            "role_name": "vault admin",
            "can_witness_eln": true,
            "projects": [
                    "name": "CharlieW Project",
                    "id": 8745,
                    "can_manage_project": true,
                    "can_edit_data": true,
                    "hidden": false
