- Drug discovery is the initial stage of drug research and development. Through early research, the genetic functions and targets of target diseases are selected and confirmed, the lead compounds are screened and optimized, and the druggability studies such as early safety screening and drug modification are carried out to obtain druggability candidate compounds.Medicilon’s drug discovery service is divided into two departments: Chemistry and Biology, with chemical and biological laboratories, equipped with SFC, Biacore 8K, microplate reader, LC-MS, HPLC and other instruments, including protein purification labs, cell culture labs, protein crystal labs and drug discovery and screening platforms.Medicilon’s Advantages:Flexible service models, including FTE and FFS, to meet diverse needs and priorities;Innovative technologies to meet novel R&D demands: AI-aided drug design, structure-based drug discovery (SBDD), fragment-based drug discovery (FBDD), DNA-encoded chemical library (DEL) technology, PROTAC, etc.Best overall value: strong expertise and capability, rapid turnaround time, full regulatory compliance;Accumulating a lot of customer cooperation experience: to maintain long -term cooperative relationships with many domestic and foreign large pharmaceutical companies and innovative new drug research and development companies.Well-developed biology sharing service platform: 10+ years of cooperation with Shanghai Synchrotron Radiation Facility (SSRF), protein free rooms, purification rooms, cell culture rooms, and BSL-2 laboratories.
