Using the MTT test, these terpolymers were established to be low toxic for non-tumor Vero cells and HeLa tumor cells. Polymer compositions of hydrophobic dye methyl pheophorbide a (MPP) based on studied terpolymers and linear polyvinylpyrrolidone (PVP) were obtained and characterized in water solution. Quantum-chemical modeling of the MPP-copolymer structures was conducted, and the possibility of hydrogen bond formation between terpolymer units and the MPP molecule was shown. Using fluorescence microscopy, the accumulation and distribution of polymer particles in non-tumor (FetMSC) and tumor (HeLa) cells was studied, and an increase in the accumulation of MPP with both types of particles was found.<\/jats:p>","DOI":"10.3390\/ijms25158422","type":"journal-article","created":{"date-parts":[[2024,8,1]],"date-time":"2024-08-01T15:26:53Z","timestamp":1722526013000},"page":"8422","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["New Amphiphilic Terpolymers of N-Vinylpyrrolidone with Acrylic Acid and Triethylene Glycol Dimethacrylate as Promising Drug Delivery: Design, Synthesis and Biological Properties In Vitro"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8269-8630","authenticated-orcid":false,"given":"Svetlana V.","family":"Kurmaz","sequence":"first","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman I.","family":"Komendant","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgenia O.","family":"Perepelitsina","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3967-9631","authenticated-orcid":false,"given":"Vladimir A.","family":"Kurmaz","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7574-0140","authenticated-orcid":false,"given":"Igor I.","family":"Khodos","sequence":"additional","affiliation":[{"name":"Institute of Microelectronics Technology and High-Purity Materials, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0381-7695","authenticated-orcid":false,"given":"Nina S.","family":"Emelyanova","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia V.","family":"Filatova","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vera I.","family":"Amozova","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastasia A.","family":"Balakina","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2259-8184","authenticated-orcid":false,"given":"Alexey A.","family":"Terentyev","sequence":"additional","affiliation":[{"name":"Federal Research Center of Problems of Chemical Physics and Medicinal Chemistry, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"887","DOI":"10.1016\/j.progpolymsci.2011.01.001","article-title":"Polymer nanoparticles: Preparation techniques and size-control parameters","volume":"36","author":"Rao","year":"2011","journal-title":"Prog.
