Antileukemia and Anticolorectal Cancer Activity of Janus Dendrimer Conjugates with Naproxen and Ibuprofen

Abstract

AbstractThe synthesis of a non‐steroidal anti‐inflammatory dendritic drug carrier, naproxen and ibuprofen‐based poly‐ester Janus dendrimer was carried out using a conventional azide‐alkyne click‐chemistry reaction. The corresponding dendron linkers contain naproxen and ibuprofen drug moieties on the surface and a stable [1,2,3]‐triazole as focal nucleus. The Janus dendrimer conjugate with four naproxen in one face and four ibuprofen on the other face was very active against human chronic myelogenous leukemia (K‐562) and human colorectal adenocarcinoma (HCT‐15) cells compared with cisplatin. This design provided an effective pathway for the synthesis of multiple drug carriers with two or more different end drugs in the structure.
