The rapid (7–45 s, depending on the polymer concentration) in situ solidifications of the hydrogel were evoked by the evolving Schiff-base bonds between the aldehyde groups of modified PVA (4-formyl benzoate PVA, PVA-CHO, 5.9 mol% functionalization degree) and the amino groups of 3-mercaptopropionate chitosan (CHIT-SH). The successful modification of the initial polymers was confirmed by both FTIR and NMR measurements; moreover, a new peak appeared in the FTIR spectrum of the 10% w/v PVA-CHO/CHIT-SH hydrogel at 1647 cm−1, indicating the formation of a Schiff base (–CH=N–) and confirming the interaction between the NH2 groups of CHIT–SH and the CHO groups of PVA-CHO for the formation of the dynamic hydrogel. The reaction between the NH2 and CHO groups of the modified biopolymers resulted in a significant increase in the hydrogel’s viscosity which was more than one thousand times greater (9800 mPa·s) than that of the used polymer solutions, which have a viscosity of only 4.6 and 5.8 mPa·s, respectively. Furthermore, the initial chitosan was modified with mercaptopropionic acid (thiol content = 201.85 ± 12 µmol/g) to increase the mucoadhesive properties of the hydrogel. The thiolated chitosan showed a significant increase (~600 mN/mm) in adhesion to the pig intestinal membrane compared to the initial one (~300 mN/mm). The in vitro release of tilorone from the hydrogel was controlled with the crosslinking density/concentration of the hydrogel; the 10% w/v PVA-CHO/CHIT-SH hydrogel had the slowest releasing (21.7 h−1/2) rate, while the 2% w/v PVA-CHO/CHIT-SH hydrogel had the fastest releasing rate (34.6 h−1/2). Due to the characteristics of these hydrogels, their future uses include tissue regeneration scaffolds, wound dressings for skin injuries, and injectable or in situ forming drug delivery systems. Eventually, we hope that the developed hydrogel will be useful in the local treatment of muscle atrophy, such as laryngotracheal atrophy.}, year = {2022}, eissn = {1999-4923}, orcid-numbers = {Abdelghafour, Mohamed M./0000-0002-7895-4555; Imre-Deák, Ágota/0000-0002-6781-1727; Kiss, Tamás/0000-0003-0011-0501; Budai-Szűcs, Mária/0000-0001-5187-5702; Katona, Gábor/0000-0003-1564-4813; Ambrus, Rita/0000-0001-5496-1710; Lőrinczi, Bálint/0000-0001-7773-0034; Keller-Pintér, Anikó/0000-0002-4105-8458; Szatmári, István/0000-0002-8571-5229; Rovó, László/0000-0003-1782-1756; Janovák, László/0000-0002-2066-319X} } @article{MTMT:32893726, title = {Use of Self-Assembled Colloidal Prodrug Nanoparticles for Controlled Drug Delivery of Anticancer, Antifibrotic and Antibacterial Mitomycin}, url = {https://m2.mtmt.hu/api/publication/32893726}, author = {Abdelghafour, Mohamed M. and Imre-Deák, Ágota and Szabó, Diána and Dékány, Imre and Rovó, László and Janovák, László}, doi = {10.3390/ijms23126807}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {23}, unique-id = {32893726}, issn = {1661-6596}, year = {2022}, eissn = {1422-0067}, orcid-numbers = {Abdelghafour, Mohamed M./0000-0002-7895-4555; Imre-Deák, Ágota/0000-0002-6781-1727; Dékány, Imre/0000-0001-5472-5355; Rovó, László/0000-0003-1782-1756; Janovák, László/0000-0002-2066-319X} } @article{MTMT:33003489, title = {Functionalized Mesoporous Silica Nanoparticles for Drug-Delivery to Multidrug-Resistant Cancer Cells}, url = {https://m2.mtmt.hu/api/publication/33003489}, author = {Igaz, Nóra and Bélteky, Péter and Kovács, Dávid and Papp, Csaba Gergő and Rónavári, Andrea and Szabó, Diána and Gácser, Attila and Kónya, Zoltán and Csontné Kiricsi, Mónika}, doi = {10.2147/IJN.S363952}, journal-iso = {INT J NANOMED}, journal = {INTERNATIONAL JOURNAL OF NANOMEDICINE}, volume = {17}, unique-id = {33003489}, issn = {1176-9114}, abstract = {Background: Multidrug resistance is a common reason behind the failure of chemotherapy. Even if the therapy is effective, serious adverse effects might develop due to the low specificity and selectivity of antineoplastic agents. Mesoporous silica nanoparticles (MSNs) are promising materials for tumor-targeting and drug-delivery due to their small size, relatively inert nature, and extremely large specific surfaces that can be functionalized by therapeutic and targeting entities. We aimed to create a fluorescently labeled MSN-based drug-delivery system and investigate their internalization and drug-releasing capability in drug-sensitive MCF-7 and P-glycoprotein-overexpressing multidrug-resistant MCF-7 KCR cancer cells.Methods and Results: To track the uptake and subcellular distribution of MSNs, particles with covalently coupled red fluorescent Rhodamine B (RhoB) were produced (RhoB@MSNs). Both MCF-7 and MCF-7 KCR cells accumulated a significant amount of RhoB@MSNs. The intracellular RhoB@MSN concentrations did not differ between sensitive and multidrug-resistant cells and were kept at the same level even after cessation of RhoB@MSN exposure. Although most RhoB@MSNs resided in the cytoplasm, significantly more RhoB@MSNs co-localized with lysosomes in multidrug-resistant cells compared to sensitive counterparts. To examine the drug-delivery capability of these particles, RhoB@Rho123@MSNs were established, where RhoB-functionalized nanoparticles carried green fluorescent Rhodamine 123 (Rho123) -a P-glycoprotein substrate - as cargo within mesopores. Significantly higher Rho123 fluorescence intensity was detected in RhoB@Rho123@MSN-treated multidrug-resistant cells than in free Rho123-exposed counterparts. The exceptional drug-delivery potential of MSNs was further verified using Mitomycin C (MMC)-loaded RhoB@MSNs (RhoB@MMC@MSNs). Exposures to RhoB@MMC@MSNs significantly decreased the viability not only of drug-sensitive but of multidrug-resistant cells and the elimination of MDR cells was significantly more robust than upon free MMC treatments.Conclusion: The efficient delivery of Rho123 and MMC to multidrug-resistant cells via MSNs, the amplified and presumably prolonged intracellular drug concentration, and the consequently enhanced cytotoxic effects envision the enormous potential of MSNs to defeat multidrug-resistant cancer.}, year = {2022}, eissn = {1178-2013}, pages = {3079-3096}, orcid-numbers = {Igaz, Nóra/0000-0003-1580-4397; Papp, Csaba Gergő/0000-0003-4450-0667; Rónavári, Andrea/0000-0001-7054-0975; Kónya, Zoltán/0000-0002-9406-8596; Csontné Kiricsi, Mónika/0000-0002-8416-2052} } @article{MTMT:31794441, title = {Reversal of multidrug resistance and antitumor promoting activity of 3-oxo-6β-hydroxy- β-amyrin isolated from Pistacia integerrima}, url = {https://m2.mtmt.hu/api/publication/31794441}, author = {ABDUR, RAUF and SAUD, BAWAZEER and MUSLIM, RAZA and EMAN, EL-SHARKAWY and MD., HABIBUR RAHMAN and MOHAMED, A.

Resistance to one drug carries over resistance to unrelated anticancer drugs leading to multidrug resistance (MDR). A major factor of MDR is P-glycoprotein (P-gp) mediated ABC transport found in many eukaryotic cells. P-gp acts as a drug eMux pump. The mdr1 gene involved in P-gp 170 protein production is localized in the human chromosome 7 band p2 1.0-21.1. Point mutations after cross-resistance patterns. A variety of stimuli increase the expression of the mdr1 gene: lowered extracellular pH, heat shock, arsenite, cytotoxic agents, anticancer drugs, transfection with oncogenes, HIV-I, and UV-irradiation. An alternative hypothesis to the efflux pump claims that P-gp modifies the intracellular environment to reduce accumulation of anticancer drugs in cancer cells by creating ionic or proton gradients. Chemosensitizers that block P-gp drug extrusion are generally lipid-soluble at physiological pH, possess a basic nitrogen atom and at least two co-planar rings. P-gp blocking does not depend on drug chirality. This opens the way of treating P-gp related MDR with chiral versions of drugs relatively harmless in terms of side-effects.

The TFP-V(IV) complex was effective at a lower concentration than TFP alone. The inhibitory effect of some metal coordinating complexes (TFP-Cu(II) and TFP- V(IV)) exceeded the action of TFP alone on efflux pumps. We propose that these compounds can form a complex with the regulatory protein or DNA resulting in the inhibition of SOS response and inhibit the mdr function by inactivating the P-glycoprotein as well.}, keywords = {Animals; MICE; Drug Resistance, Multiple/*genetics; Mitomycin/pharmacology; SOS Response (Genetics)/*drug effects; Phenothiazines/chemistry/*pharmacology; P-Glycoprotein/biosynthesis; Metals/chemistry/*pharmacology; Megacins/biosynthesis; Lymphoma, T-Cell/metabolism; Gene Expression Regulation, Bacterial/*drug effects; DNA, Neoplasm/drug effects/metabolism; DNA, Bacterial/drug effects/metabolism; Bacillus megaterium/drug effects/metabolism; Antibiotics, Antineoplastic/pharmacology}, year = {1998}, eissn = {1791-7530}, pages = {3093-3098}, orcid-numbers = {Ocsovszki, Imre/0000-0003-1290-996X} }
