The present invention relates to the use of a compound containing a moiety of formula (I) as a reagent for linking a compound of formula R1—H which comprises a first functional moiety of formula F1 to a second functional moiety of formula F2
wherein X, X′, Y, R1, F1 and F2 are as defined herein. The present invention also provides related processes and products. The present invention is useful for creating functional conjugate compounds, and specifically conjugates in which at least one of the constituent molecules carries a thiol group.
is shown to be stable to serum protein albumin but unstable in intracellular conditions. A derivatised analogue underwent self-immolative degradation in cellular thiol conditions as evidenced by LC-MS/release of a turn-on fluorescence fluorophore; versatility of the thiol-pyridazinedione is demonstrated through synthesis of SMDC precursors that contain three different functional groups on the same central

Herein we report a thiol-labile cysteine protectinggroup based on an unsaturated pyridazinedione (PD) scaffold. We establish compatibility of the PD in conventional solidphasepeptidesynthesis (SPPS), showcasing this in the on-resin synthesis of biologically relevant oxytocin. Furthermore, we establish the applicability of the PD protectinggroup towards both microwave-assisted SPPS and native chemical
