4A-BFA-11
4A-BFA-11 is a folate-targeted PEG-MMAE conjugate that exhibits specific binding affinity for the folate receptor α (FR-α) (KD = 106.7 nM). 4A-BFA-11 achieves tumor enrichment by combining PEG-mediated long circulation (EPR effect) and folate receptor targeting. 4A-BFA-11 undergoes enzymatic cleavage at the tumor site to release the active payload, enabling precise action. 4A-BFA-11 sefficiently carries, targets, and controls the release of MMAE in tumor tissues in a HeLa mouse model. 4A-BFA-11 can be used for cervical cancer, ovarian cancer, and lung cancer research.

Animal Model:BALB/c nude mice (5-6 weeks) inoculated with HeLa graft tumors in the right axilla[1]
-
Dosage:0.4 and 0.8 mg/kg
-
Administration:i.v., once weekly for 2 weeks
-
Result:Resulted in stronger antitumor effects with a tumor growth inhibition rate (T/C%) of 67.1% at 0.4 mg/kg.
Achieved pronounced antitumor effects with a T/C% of 95.9% at 0.8 mg/kg.
Showed no significant body weight loss and no significant changes in blood parameters.
Induced mild hepatitis at 0.4 mg/kg, characterized by trace inflammatory cell infiltration predominantly composed of lymphocytes and granulocytes.
Exhibited mild sinusoidal dilatation in the spleen, and the low-dose group showed slight adhesion of the white pulp.
