Cys-LT7
Based on 1 Customer Validation
Cys-LT7 is a transferrin receptor (TfR)-targeting peptide ligand. Cys-LT7 binds to a TfR site distinct from endogenous transferrin, mediates conjugated Doxorubicin (HY-15142A) delivery to TfR-overexpressed tumor cells, and exhibits low toxicity to TfR-low-expressed normal cells. Cys-LT7 is an L-configuration peptide susceptible to proteolytic enzymes, leading to poor biostability in peptide-drug conjugates. Cys-LT7 can be used for the research of glioblastoma, hepatocellular carcinoma, lung carcinoma.

Biological Activity
Cys-LT7 conjugated with Doxorubicin exhibits poor serum stability in mouse serum, with a half-life of 0.37 h and nearly complete degradation by 1 h[1].
Cys-LT7 conjugated with Doxorubicin undergoes rapid reduction-triggered degradation in 5 mM GSH (complete degradation by 1 h, T1/2 = 0.26 h) and slower degradation in 5 µM GSH (71.4% intact after 24 h)[1].
Cys-LT7 conjugated with Doxorubicin is selectively taken up into the cytoplasm of TfR-overexpressed A549, HepG2, and U87 tumor cells (with time-dependent uptake) but shows minimal uptake into TfR-low-expressed LO2 normal cells[1].
Cys-LT7 conjugated with Doxorubicin exhibits weak in vitro antiproliferative activity against TfR-overexpressed U87, HepG2, and A549 tumor cells, with higher cell viability maintained even at an equivalent Doxorubicin concentration of 40 µM after 48 h of incubation[1].
