| Popis: | S)-Camptothecin (CPT)-conjugated dipep- tides are reported that preassemble into nanotubes with diameters ranging from 80-120 nm. These nanoassemblies maintain a high (~ 47 %) drug loading and exhibit greater drug stability (i.e., resistance to lactone hydrolysis), and consequently greater efficacy against several human cancer cells (HT-29, A549, H460, and H23) in vitro com- pared with the clinically used prodrug irinotecan. A key and defining feature of this system is the use of the CPT- conjugated dipeptide as both the drug and precursor to the nanostructured carrier, which simplifies the overall fabrication process. |
