Spatial Tumour Tissue Distribution Dynamics of a Bicycle Peptide-MMAE Toxin Conjugate Profiled by Targeted Mass Spectrometry
Start here
Laser capture microdissection coupled to targeted LC-PRM mass spectrometry maps the spatial distribution of MMAE released from the NECTIN-4-binding Bicycle Drug Conjugate zelenectide pevedotin (BT8009) at sub-tissue resolution in mice. The method showed progressive accumulation and sustained retention of MMAE in tumour tissues over 24 h, while levels in plasma, liver and muscle declined after early exposure, and revealed heterogeneous MMAE distribution between tumour cell-rich and stroma-rich regions with distinct temporal patterns.
