MIP-1072
MIP-1072 is a competitive prostate-specific membrane antigen (PSMA) inhibitor with a Ki value of 4.6 nM. MIP-1072 specifically binds to PSMA and is internalized into PSMA-expressing prostate cancer cells. MIP-1072 accumulates in PSMA-expressing prostate cancer xenografts. MIP-1072 specifically blocks the uptake of 68Ga-NOTA-GUL by PSMA-positive prostate cancer xenografts. When radiolabeled with 123I, MIP-1072 functions as a SPECT/CT molecular imaging agent. MIP-1072 can be used in prostate cancer-related research.

MIP-1072 (1-10000 nM; 30 min) potently inhibits the NAALAD enzymatic activity of PSMA in prostate cancer LNCaP cell lysates, with a Ki value of 4.6 nM[1].
[123I]MIP-1072 (3 nM; 1 h) binds specifically to PSMA-positive prostate cancer LNCaP cells, but does not bind to PSMA-negative prostate cancer PC3 cells; this binding is inhibited by non-radioactively labeled MIP-1072 (10 µM; 1 h)[1].
[123I]MIP-1072 (100 nM; 0-2 h) undergoes internalization into prostate cancer LNCaP cells in a temperature- and time-dependent manner at 37 °C[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
123I-MIP-1072 (74 kBq/mouse; i.v.; single bolus injection) tumor uptake is directly proportional to tumor mass (overall R2 = 0.7605; combined treatment groups R2 = 0.7066), enabling tracking of changes in tumor size in response to paclitaxel therapy in LNCaP xenograft-bearing mice[2].
MIP-1072 (50 mg/kg; single co-injection with 68Ga-NOTA-GUL) specifically blocks 68Ga-NOTA-GUL uptake in PSMA-positive prostate cancer xenografts in BALB/c nude mice, reducing tumor SUVmean to 0.098[3].

Animal Model:Fox Chase SCID (male, xenograft model via implantation of LNCaP, PC-3 PIP, or PC-3 flu cells, used when tumors reached 5-7 mm in diameter)[1]
-
Dosage:1 mCi/mouse
-
Administration:i.v.; single dose
-
Result:Showed high, selective uptake in PSMA-expressing LNCaP tumors and kidneys at 4 hours post-injection via SPECT/CT imaging.
Detected PSMA-positive PC-3 PIP tumors but showed no uptake in PSMA-negative PC-3 flu tumors at 2 hours post-injection via SPECT/CT imaging.
-
Animal Model:NCr-nu/nu (male, athymic, LNCaP human prostate cancer xenograft)[2]
-
Dosage:~74 kBq/mouse
-
Administration:i.v.; single bolus injection
-
Result:Showed an overall linear correlation with tumor mass (R2 = 0.7605).
Increased from 2.17 %ID on day 2 to 3.93 %ID on day 23 in vehicle-treated mice, corresponding to increased tumor growth (mean tumor mass increased from 222 mg to 415 mg).
Reached 2.34 %ID on day 23 in paclitaxel-treated mice, not significantly different from day 2 vehicle-treated mice, consistent with inhibited tumor growth (mean tumor mass 161 mg).
Reached 10.0 %ID/g (day 2 vehicle), 9.8 %ID/g (day 23 vehicle), and 13.3 %ID/g (day 23 paclitaxel).
Showed a linear correlation with tumor mass in combined treatment groups (R2 = 0.7066).
