Researchers have developed a targeted co-delivery nanosystem combining methotrexate and curcumin using PAMAM dendrimer, significantly improving therapeutic efficacy against cervical cancer.
The study focuses on the creation of Cur-PAMAM-MTX nanocomplexes using PAMAM dendrimer for simultaneous delivery of methotrexate and curcumin, showing enhanced cytotoxicity against cervical cancer cells.
The research was conducted by Aghanejad, Kheiriabad, Ghaffari, and others at Tabriz University of Medical Sciences and supported by the National Natural Science Foundation of China.
The research findings were published on 2025-01-30.
The research was performed at Tabriz University of Medical Sciences, Iran.
The goal is to increase the efficiency of cancer treatment by reducing drug dosages and enhancing the targeting of cancer cells to minimize side effects.
The PAMAM dendrimer was modified to chemically bind methotrexate and encapsulate curcumin; particle size, drug release kinetics, and cytotoxicity were assessed using various laboratory techniques like FT-IR, MTT assays, and UV-vis spectroscopy.
The nanosystem improved the solubility and stability of curcumin and demonstrated controlled release under different pH conditions, mimicking the tumor environment.
"The co-delivery NC shows promise for additional in vitro investigations and possesses the capacity to function as an effective framework for the combined delivery of MTX and Cur in cervical cancer chemotherapy."
"Curcumin possesses the capacity to impact diverse cell signaling pathways, showcasing a multifaceted therapeutic impact in cancer treatment."
"The findings indicated the potential utility of Cur-PAMAM-MTX NC for delivering two anticancer agents."
