TATE-DA-I
TATE-DA-I is a somatostatin receptor 2 (SSTR2) ligand with an IC50 of 25.3 nM. TATE-DA-I binds to albumin to prolong its circulation retention time and also exhibits enhanced tumor accumulation capacity. TATE-DA-I enables clear visualization of SSTR2-positive tumors in SPECT/CT imaging. TATE-DA-I can be used in cancer-related research.

TATE-DA-I inhibits SSTR2 binding on AR42J cells with an IC50 of 25.3 nM, and its potency is significantly lower than that of DOTA-TATE (HY-106244)[1].
TATE-DA-I radiolabeled derivative [111In]In-TATE-DA-I shows high in vitro stability in mouse plasma and human plasma after incubation at 37 °C for 24 h[1].[1].
TATE-DA-I radiolabeled derivative [111In]In-TATE-DA-I specifically binds to somatostatin receptor 2 (SSTR2) on AR42J cells[1].
TATE-DA-I radiolabeled derivative [111In]In-TATE-DA-I displays the highest relative binding activity to human serum albumin among all tested radioligands, and its binding rate rises as HSA concentration increases[1].
