Biological Activity
[177Lu]Lu-PSMA-1-DOTA (111 MBq total, 4 doses of 27.75 MBq over 2 days; 111 MBq single dose; i.v.) effectively inhibits tumor growth in PC3pip xenograft mice for 24 days[1].
[68Ga]Ga-PSMA-1-DOTA (7.4 MBq; i.v.) targets PC3pip tumors with minimal non-target uptake in kidneys and salivary glands in xenograft mice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:athymic nude [Foxn1/nu/Foxn1/nu] (male, 6-8 weeks old, PC3pip subcutaneous xenograft model)[1]
-
Dosage:111 MBq (3 mCi) total, 4 doses of 27.75 MBq each over 2 days; 111 MBq (3 mCi) single dose
-
Administration:i.v.; 4 doses over 2 days (day 0); single dose (day 13)

Animal Model:athymic nude [Foxn1/nu/Foxn1/nu] (male, PC3pip subcutaneous xenograft model)[1]
-
Dosage:7.4 MBq (200 μCi)
-
Administration:i.v.
-
Result:Showed significantly lower kidney and salivary gland uptake compared to [⁶⁸Ga]Ga-PSMA-11 and [⁶⁸Ga]Ga-PSMA I&T; reached tumor-to-left salivary gland ratio of 13.45 at 30 minutes and 27.43 at 1 hour post-injection.

Animal Model:NMRI (male, 8 weeks old)[1]
-
Dosage:1.4 mg/kg
-
Administration:i.v.; single dose
-
Result:Observed no mortality, significant body weight changes, or abnormal clinical signs; detected no significant changes in clinical chemistry parameters on day 2 or day 15; identified test item-related histopathological changes in spleen, bone marrow, and inguinal lymph nodes (present after 14-day recovery).
