Synthesis and Quantitative Structure–Activity Relationship of Imidazotetrazine Prodrugs with Activity Independent of O6-Methylguanine-DNA-methyltransferase, DNA Mismatch Repair and p53. [PDF]

, 2013
The antitumor prodrug Temozolomide is compromised by its dependence for activity on DNA mismatch repair (MMR) and the repair of the chemosensitive DNA lesion, O6-methylguanine (O6-MeG), by O6-methylguanine-DNA-methyltransferase (EC 2.1.1.63, MGMT). Tumor

Systematic screening of different polyglycerin‐based dienophile macromonomers for efficient nanogel formation through IEDDA inverse nanoprecipitation [PDF]

, 2019
Alternatives for strain‐promoted azide–alkyne cycloaddition (SPAAC) chemistries are needed because of the employment of expensive and not easily scalable precursors such as bicyclo[6.1.0]non‐4‐yne (BCN).

Cross-coupling Reactions of Monosubstituted Tetrazines [PDF]

Organic Letters, 2021
A fast and mild method for the Pd-catalyzed cross-coupling reaction of monosubstituted 3-bromo-1,2,4,5-tetrazine is presented. Investigation of silver-based additives revealed that Ag2CO3 is the optimal mediator, enabling the process without the need for strong bases or high temperatures.
