System Specifications and Precautions on the Use of CzeekD ASP

  1. System Overview
    The system is referred as CzeekD and is oferred under ASP (Application Service Provider). It is a fragment-based de novo compound design system utilizing RECAP, CGBVS, PSO to generate optimized compound structures (the process is summarized in the figure below). The technology behind the CzeekD system has been recently granted a Japanese patent (Patent No. 5946045). In CGBVS, ChEMBL models are provided for the free use of CzeekD. To check the models available for use with CzeekD please follow this link. For the list of target protein covered by each model please check this link.
  2. ※ RECAP - Retrosynthetic Combinatorial Analysis Procedure
        CGBVS - Chemical Genomics-Based Virtual Screening
        PSO - Particle Swarm Optimization

    Below are screenshots of the settings and results window within the CzeekD ASP system.

  3. How to apply
    Those who would like to avail the use of CzeekD may register using this form after which a username and password will be provided. Applicants should agree to the terms of use in order to be able to apply. Once registered, accounts are generally effective until the end of June each year and should be renewed for continuous access of the service.

  4. Accessing the service
    Registered users can access the service using a web browser to login to the CzeekD server. Compatible browsers are listed below.
    1. Windows 10 (IE 11, Edge, Chrome) [32 and 64 bit]
    2. Mac OS X 10.11 (Firefox, Chrome, Safari) [64 bit]

  5. System configuration and important notes
    The system is composed of a job management server and a calculation server. Due to the calculation server limitation, only 1 job runs at a particular time. A user can only submit 3 jobs at a time, including a currently running job. If a user is found to have submitted more than that number of jobs, the excess job will be removed from the queue or stopped without prior notice. Stopped jobs can be resubmitted if the user does not exceed the allowed limit. Furthermore, if a particular running job is found not exhibiting signs of activity for a large amount of time, it will be aborted without prior notice. Aborted jobs can be resubmitted by first resetting the parameters of the job before submission in order to prevent possible reoccurrence of job "hanging".

  6. Saving calculation data
    After checking the results of calculation within CzeekD, the user can select desired compound structures then donwload them in sdf or csv format. Since we do not provide storage and backup of user data, it is recommended to download your data and delete copies from the server, at the latest, until the end of the current fiscal year. Files that still exist one(1) week into the succeeding fiscal year will be deleted without prior notice. Please take note that recovery of deleted data is not possible.

  7. Disclaimer
    Kyoto Constella Technologies is not responsible for, and expressly disclaims all liability for damages of any kind arising out of use of the service.
