Description: XQN70430, also known as MC-​Ala-​Ala-​Asn(Trt)​-​PAB, is a hetero bifunctional cross-linker, useful in antibody drug conjugation (ADC). XQN70430 is a fissionable linker which is specifically activated in a tumor microenvironment. XQN70430 was reported in patent WO 2016026458. This product has no formal name at the moment. For the convenience of communication, a temporal code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
