Progress Report: PHGDH ACT Domain — Lead Optimization for CNS-Penetrant AD Therapeutic (Cycle 8)
Executive Summary
New data was added this cycle, with updated rankings and key findings. The top-ranked compound, cc_c_ccn1c_cn2ccn_c__o_c, maintained its position with a total score of 0.96.
Research Progress
In this cycle, we continued to optimize the analog pool and refine the MCDA scores to identify the best candidates for CNS-penetrant AD therapeutic development. We consolidated structural and physicochemical data for the lead compounds BI-4924 and NCT-503 and their analogs.
