| 生物活性 | MEDI3726 (ADCT-401) exhibits potent, specific cytotoxicity in PSMA-expressing prostate cancer cell lines, with greatly reduced activity in PSMA-negative prostate cancer cell lines [3]. MEDI3726 (0.2 ug/mL; 1 h) cross-reacts with human and cynomolgus monkey soluble PSMA with similar potency, but does not cross-react with rat soluble PSMA [4]. MEDI3726 (up to 7 days) remains stable and active at 37°C in PBS, human plasma, or cynomolgus monkey plasma [4]. MEDI3726 (5-7 days) potently and specifically kills PSMA-positive human prostate cancer cell lines LNCaP (IC 50 = 0.02 nM), LNCaP C4-2 (IC 50 = 0.06 nM), MDA PCa 2b (IC 50 = 0.002 nM), and CWR22Rv1 (IC 50 = 0.29 nM), but shows no targeted cytotoxicity in PSMA-negative PC-3 (IC 50 = 29.3 nM) and DU145 cell lines (IC 50 = 44.9 nM) [4]. MEDI3726 (24 h) is specifically internalized and trafficked to lysosomes in PSMA-positive LNCaP cells, but not in PSMA-negative PC-3 cells [4]. MEDI3726 (6 nM; 2 h treatment) induces persistent DNA interstrand crosslinks in PSMA-positive LNCaP cells, but does not induce significant DNA crosslinking in PSMA-negative PC-3 cells [4]. catabolism primarily via heavy-light chain dissociation, with minimal warhead deconjugation. MEDI3726 can be used for the research of metastatic castration-resistant prostate cancer and prostate cancers [1] [2] [3] [4]. |

| 背景 | Glutamate carboxypeptidase 2 (FOLH1/PSMA) is a ~84 kDa protein. Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Involved in prostate tumor progression. |
