Abstract:
Zelenectide pevedotin is a Nectin-4 targeting Bicycle drug conjugate® (BDC®) that has fast track designation for the treatment of bladder, breast, and lung cancers. Its structure is highly complex and comprises a Bicycle connected to microtubule inhibitor monomethyl aurostatin-E (MMAE) via a molecular spacer and a cleavable linker. This provides a unique challenge in structural elucidation, and this report shows a strategy to overcome this using an incremental, nuclear magnetic resonance spectroscopy-based approach, which may be applied to complex structures of a similar nature.

Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied...
Structure of Conjugated Dienes
Conjugated dienes are compounds characterized by the presence of alternating double and single bonds. In a conjugated system like 1,3-butadiene, the unhybridized 2p orbital on each carbon overlaps continuously, allowing the π electrons to be delocalized across the entire molecule. In contrast, this type of overlap does not occur in cumulated and isolated dienes, such as 2,3-pentadiene and 1,4-pentadiene, respectively. Instead, the π electrons remain localized between the double...
