Alloc-Val-Ala-OH - CAS 330970-70-2

Alloc-Val-Ala-OH (((Allyloxy) carbonyl) -L-valyl-L-alanine) serves as a building block in the synthesis of Tesirine, which is a clinical antibody-drug conjugate (ADC) featuring a pyrrolobenzodiazepine (PBD) dimer payload. The Val-Ala sequence is cleaved specifically by cathepsin B. The Alloc group is stable towards piperidine and TFA, yet can be easily removed under mild conditions via palladium-catalyzed allyl transfer.
