We aimed to investigate the effect of a third-generation TKI, ponatinib on platelet functions. Materials and Methods: Collagen-induced platelet aggregation and coated-platelet formation were examined using in vitro and in ex vivo samples of patients on ponatinib therapy. Results: In platelet rich plasma of healthy volunteers, ponatinib at a supra- therapeutic concentration (1,000 nM) significantly impaired collagen induced platelet aggregation (p <= 0.01) and reduced the formation of coated-platelets at 150 nM ponatinib concentration ( p <= 0.05). In addition, upon glycoprotein VI (GPVI) receptor activation, a significantly lower percentage of PAC1 binding platelets (p <= 0.05) was observed at 1,000 nM final concentration of ponatinib. Platelets, isolated from patients on ponatinib therapy showed impaired collagen elicited aggregation response, already in pre-dose samples compared to healthy donors. Conclusion: The therapeutic concentration of ponatinib impairs platelet activation processes elicited by GPVI receptor agonists.}, keywords = {Platelet function; Laboratory testing; Ponatinib therapy}, year = {2021}, eissn = {1791-7530}, pages = {4867-4874} } @article{MTMT:32285360, title = {A krónikus myeloid leukaemia tirozin-kináz-gátló kezelésének mellékhatásai és azok gyakorlati ellátása = Practical management of side effects of tyrosine kinase inhibitor therapy in chronic myeloid leukemia}, url = {https://m2.mtmt.hu/api/publication/32285360}, author = {Mezei, Gabriella and Illés, Árpád and Batár, Péter}, doi = {10.1556/650.2021.32177}, journal-iso = {ORV HETIL}, journal = {ORVOSI HETILAP}, volume = {162}, unique-id = {32285360}, issn = {0030-6002}, year = {2021}, eissn = {1788-6120}, pages = {1198-1207} } @article{MTMT:31385279, title = {Imidazo[1,2-b]pyrazole-7-Carboxamide Derivative Induces Differentiation-Coupled Apoptosis of Immature Myeloid Cells Such as Acute Myeloid Leukemia and Myeloid-Derived Suppressor Cells}, url = {https://m2.mtmt.hu/api/publication/31385279}, author = {Kotogány, Edit and Balog, József Ágoston and Nagy, Lajos I. and Alföldi, Róbert and Bertagnolo, Valeria and Brugnoli, Federica and Demjén, András and Kovács, Anita Kármen and Batár, Péter and Mezei, Gabriella and Szabó, Renáta and Kanizsai, Iván and Varga, Csaba and Puskás, László and Szebeni, Gábor}, doi = {10.3390/ijms21145135}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31385279}, issn = {1661-6596}, year = {2020}, eissn = {1422-0067}, orcid-numbers = {Kovács, Anita Kármen/0000-0001-9805-1647; Varga, Csaba/0000-0002-2678-665X; Szebeni, Gábor/0000-0002-6998-5632} } @article{MTMT:32005205, title = {Dasatinib inhibits coated-platelet generation in patients with chronic myeloid leukemia}, url = {https://m2.mtmt.hu/api/publication/32005205}, author = {Mezei, Gabriella and Bekéné Debreceni, Ildikó and Kerenyi, Adrienne and Reményi, Gyula and Szász, Róbert and Illés, Árpád and Kappelmayer, János and Batár, Péter}, doi = {10.1080/09537104.2018.1501470}, journal-iso = {PLATELETS}, journal = {PLATELETS}, volume = {30}, unique-id = {32005205}, issn = {0953-7104}, year = {2019}, eissn = {1369-1635}, pages = {836-843}, orcid-numbers = {Szász, Róbert/0000-0003-1343-6017} } @article{MTMT:31189289, title = {Dasatinib Inhibits Procoagulant and Clot Retracting Activities of Human Platelets}, url = {https://m2.mtmt.hu/api/publication/31189289}, author = {Bekéné Debreceni, Ildikó and Mezei, Gabriella and Batár, Péter and Illés, Árpád and Kappelmayer, János}, doi = {10.3390/ijms20215430}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {20}, unique-id = {31189289}, issn = {1661-6596}, year = {2019}, eissn = {1422-0067} } @article{MTMT:30319060, title = {Imidazo[1,2-b]pyrazole-7-carboxamides Induce Apoptosis in Human Leukemia Cells at Nanomolar Concentrations.}, url = {https://m2.mtmt.hu/api/publication/30319060}, author = {Szebeni, Gábor and Balog, József Ágoston and Demjén, András and Alföldi, Róbert and Végi, Vanessza L and Fehér, Z.

Eight imidazo[1,2-b]pyrazole-7-carboxamides have been tested for cytotoxic activity against five leukemia cell lines: Acute promyelocytic leukemia (HL-60), acute monocytic leukemia (THP-1), acute T-lymphoblastic leukemia (MOLT-4), biphenotypic B myelomonocytic leukemia (MV-4-11), and erythroleukemia (K-562) cells in vitro. Imidazo[1,2-b]pyrazole-7-carboxamides hampered the viability of all five leukemia cell lines with different potential. Optimization through structure activity relationship resulted in the following IC50 values for the most effective lead compound DU385: 16.54 nM, 27.24 nM, and 32.25 nM on HL-60, MOLT-4, MV-4-11 cells, respectively. Human primary fibroblasts were much less sensitive in the applied concentration range. Both monolayer or spheroid cultures of murine 4T1 and human MCF7 breast cancer cells were less sensitive to treatment with 1.5⁻10.8 μM IC50 values. Flow cytometry confirmed the absence of necrosis and revealed 60% late apoptotic population for MV-4-11, and 50% early apoptotic population for HL-60. MOLT-4 cells showed only about 30% of total apoptotic population. Toxicogenomic study of DU385 on the most sensitive MV-4-11 cells revealed altered expression of sixteen genes as early (6 h), midterm (12 h), and late response (24 h) genes upon treatment. Changes in ALOX5AP, TXN, and SOD1 expression suggested that DU385 causes oxidative stress, which was confirmed by depletion of cellular glutathione and mitochondrial membrane depolarization induction.
