FBN33428, also known as Fmoc-​Phe-​Lys(Boc)​-​PAB; is a Hydrolyzable linker for making ADC conjugate. FBN33428 is useful for making hydrolyzable prodrugs for delivery of anticancer drugs to metastatic cells. FBN33428 was first reported in WO 9813059. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
