Experiment 1 Reporting the Activity Data of This PDC [1]
Indication Tumor
Efficacy Data Cell viability
15%
Administration Time 72 h
Administration Dosage 10 µM
Evaluation Method MTS assay
Description
The cytotoxicity data for the pHLIP-PAMAM-DOX conjugate mirrored quite closely that of the pHLIP-S-S-DOX conjugate, particularly at the higher concentrations (>1.25 μM). However, at lower pHLIP concentrations (0.16 μM-0.63 μM), the PAMAM conjugate exhibited higher cytotoxicity than the single DOX conjugate (˜up to 17% higher toxicity).
