Fmoc-Gly-NH-CH2-O-Cyclopropane-CH2COOH

Fmoc-Gly-NH-CH2-O-Cyclopropane-CH2COOH serves as an intermediate for ADC linker synthesis. This linker, which includes Benzyl 2-cyclopropyl-2-hydroxyacetate, is capable of being coupled to Exatecan and subsequently linked with antibodies (such as antibody hu2F7) [1].
