Reported Iron-Core CO-Releasing Module Broadens ADC Payload Design
Crossref metadata verifies the primary paper's title, authorship, journal, DOI, and publication record. The detailed construct is reported as combining an Fe(CO)3 CO-releasing molecule, a Val-Cit-PABC trigger, and thiol conjugation to trastuzumab after interchain disulfide reduction.
A Preprint Maps siRNA 5′-Phosphate Chemistry for AGO2 Anchoring
The siRNA guide-strand 5′-phosphate is a recognition element for engagement with the AGO2 MID domain. The preprint examines a different way to modify that terminus: installing an organic substituent on a nonbridging phosphate oxygen while retaining a phosphate-centered anchoring group.
Reported PBD Dimer Chemistry for ADC Linker–Payload Design
Pyrrolobenzodiazepine (PBD) dimers join two PBD units to create a bifunctional DNA-reactive scaffold. For ADC development, the useful question is not which free payload appears most potent in an isolated assay. It is how electrophile state, linker architecture, hydrophilicity, conjugation level, release behavior, and analytical control work together in the complete linker–payload and conjugate.
GLP-1 Peptide Lipidation: Chain, Linker, and Attachment Design
Fatty-acid-derived modification can introduce an albumin-binding handle, but the chain alone does not define the conjugate. Functional group identity, linker composition, attachment position, and the peptide sequence all influence what must be synthesized, purified, and measured.
CycDockAssem: A Reported Fragment Workflow for Cyclic Peptide Design
The paper describes a de novo workflow built around four structural fragments: two are positioned at selected regions of a protein surface, and two are used to connect the docked segments into a closed backbone. Candidate scaffolds then move through geometry-based ranking, fixed-backbone sequence redesign, and molecular-dynamics-based prioritization.
ADC Payload and Linker Design: A Chemistry Review Framework
ADC linker–payload design is a coupled optimization problem: payload function sets physicochemical and analytical demands, while the linker determines attachment, stability, and the chemical form released. A 2026 review by Samson Gebretnsae describes options ranging from established cytotoxic classes to emerging immune-stimulating, degradation, metabolic, and photoactivated concepts. For R&D teams, the useful output is not a rank order of modalities but a matrix of testable material attributes.
