Abstract
Photodynamic therapy (PDT) has emerged as a non-invasive modality where photosensitizer (PS) plays an indispensable role for treating tumors. This study proposes a novel Zein nanoparticle (ZP) encapsulating Zinc phthalocyanine (ZnPc) that targets tumor through intravenous delivery. The ZPs were prepared by phase separation process. Modification of ZPs were realized through encapsulation of polydopamine (PDA) and hyaluronic acid (HA) in order to maintain photothermal, pH-responsive, and tumor-targeting properties. The physiochemical properties, in vitro release, and in vitro evaluation of photothermal and photodynamic effects were studied. The biosafety was analyzed through cytotoxicity assay using human lung cancer cell line A549 as model. The excellent biosafety and significant anti-tumor effect demonstrated that the novel ZPs can be potential candidates for the alternative treatment of cancer.
期刊介绍：
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
