Research Areas:
Mal-amide-PEG8-Val-Cit-PAB-OH is a cleavable ADC linker featuring a maleimide, a hydrophilic PEG spacer, a Val-Cit dipeptide, and a PAB functional group. Maleimide is used to covalently bind free thiols on the cysteine residues of proteins. The Val-Cit dipeptide is cleaved by cellular proteases within the cell to allow for efficient payload delivery with the help of the PAB structure.

Pt-Luc is a bioluminescent probe used for real-time, non-invasive monitoring of Pt (IV) prodrug reduction in living cells and animal models. The detection mechanism of Pt-Luc relies on the intracellular reduction mediated by active cysteine residues in proteins. Pt-Luc can penetrate the membrane of living cells; after entering cells, active cysteine thiolates in high-molecular-weight protein components reduce the Pt (IV) complex, thereby cleaving the caged aminoluciferin substrate. The released free aminoluciferin is then oxidized by luciferase in the presence of ATP to generate a bioluminescent signal, whose intensity is directly correlated with the reduction degree of Pt (IV) .

CMTDP is a Fluorescent probe for detecting local polarity changes around the Cys34 domain of bovine serum albumin during pH-induced N→B conformational transition. It is a thiol-specific and polarity-sensitive probe; it covalently labels the free cysteine residue at position 34 (Cys34) of bovine serum albumin, and its fluorescence maximum emission wavelength shifts in response to solvent polarity, but not to pH and temperature. When labeled to BSA, as the local polarity around the Cys34 domain increases with rising pH, the probe shows a bathchromic shift in fluorescence emission wavelength and a decrease in fluorescence intensity, which allows quantification of the local polarity change via the relationship between emission wavelength shift and dielectric constant. CMTDP itself has absorption peaks at ~392 and 508 nm, and CMTDP-labeled BSA has excitation maxima at 376 and 470 nm at pH 6.0, with the shorter-wavelength excitation peak red-shifting as pH increases while the longer one remains stable; when excited at 470 nm, the fluorescence emission maximum shifts from 570 nm at pH 6.0 to 577 nm at pH 9.1, while free CMTDP at pH 7.4 has an emission maximum at 621 nm. The excitation/emission wavelengths for CMTDP-labeled BSA are Ex/Em = 376/570 nm at pH 6.0, Ex/Em = ~376+/573 nm at pH 7.4, Ex/Em = ~376+/575 nm at pH 8.0, Ex/Em = ~376+/577 nm at pH 9.1, and for free CMTDP at pH 7.4, Ex/Em (when excited at 470 nm) = 470/621 nm[1].
