N-Aminofluorescein is a fluorescein hydrazide with spiro form, a highly selective and sensitive fluorescence probe for Cu 2+. N-Aminofluorescein has no selective fluorescence response to other common metal ions, can be used for direct detection of Cu 2+ in biological systems with λex/em=495/516 nm . N-Aminofluorescein can be used to measure the concentration of copper ions in cells .

closed-HMRG is an HMRG (HY-D2379) with a closed spiro-ring structure. HMRG is a fluorescent dye, which serves as the fluorescent active product generated by enzyme-activated fluorescent probes targeting proteases and glycosidases. Its detection mechanism relies on the intramolecular spirocyclization equilibrium: HMRG itself exists in an open non-spirocyclic structure under physiological pH, which maintains a conjugated π system and produces strong fluorescence; whereas its probe precursors (such as Leu-HMRG, Ac-GlyPro-HMRG and βGal-HMRG) exist in a closed spirocyclic form and show no fluorescence due to the disruption of the π-conjugated system; when the target enzyme cleaves the substrate fragment linked to the probe precursor, the closed spirocyclic structure converts to the open structure of HMRG, restoring the conjugated system and generating a strong fluorescent signal. Its detection wavelength is Ex/Em = 501/524 nm .

Spiro-duocarmycin is a DNA minor groove N3-adenine alkylating agent. Spiro-duocarmycin exerts cytotoxic effects via DNA alkylation. Spiro-duocarmycin is the active spirocyclized form of seco-DUBA, which is incorporated as an inactive prodrug into the linker-drug construct of antibody-drug conjugates (ADCs). DUBA serves as an ADC payload that can be conjugated with monoclonal antibodies to synthesize antibody-drug conjugates (ADCs) .
