BOD-Tz-TMR is a fluorescent probe used for nitric oxide (NO) detection and atherosclerotic plaque imaging.BOD-Tz-TMR has a detection limit of 31 nM for NO. BOD-Tz-TMR functions via Förster resonance energy transfer (FRET) and bioorthogonal reactions, in which the tetrazine linker quenches fluorescence through the energy transfer to dark state (ETDS) mechanism. The interaction of BOD-Tz-TMR with NO triggers a ratiometric shift in fluorescence from BODIPY (Ex/Em: 488 nm/512 nm, green channel) to TMR (Em: 592 nm, red channel). BOD-Tz-TMR labels macrophages through a bioorthogonal reaction with BCN, enabling its targeted accumulation at atherosclerotic plaque sites to detect endogenous NO associated with lesion progression. BOD-Tz-TMR can be used in studies related to atherosclerosis.

Tz-Thalidomide is a tetrazine-tagged Thalidomide (HY-14658), an E3 ligase ligand. Tz-Thalidomide self-assembles with TCO-labeled target protein inhibitors, forming a CLIP-TAC (targeted protein degradation chimera) via click chemistry. This chimera recruits the E3 ubiquitin ligase CRBN to the target protein, thereby inducing ubiquitination and subsequent degradation of the target protein. When used in combination with JQ1-TCO (HY-148864), Tz-Thalidomide induces concentration-dependent degradation of BRD4 in cells. When combined with ERK-targeting protein inhibitors, Tz-Thalidomide induces degradation of ERK1/2 in cells. Tz-Thalidomide can be used in cancer-related research.
