Cariprazine is an antipsychotic medication that has been approved for the treatment of schizophrenia and manic or mixed episodes. Patients with tumors frequently develop psychiatric disorders, necessitating the combination of antitumor and antipsychotic drugs. The objective of the present study was to examine the inhibitory impacts of three antitumor drugs (olmutinib, napabucasin and ponatinib) on the metabolism of cariprazine, and the molecular docking of cariprazine and ponatinib in relation to CYP3A4 was also evaluated. As the results, the half-maximal inhibitory concentration (IC 50 ) values of ponatinib and olmutinib in vitro were < 10 μM, whereas napabucasin was >20 μM. Among these, ponatinib exhibited the smallest IC 50 value. The metabolic stability of cariprazine was observed in the presence or absence of ponatinib in rat liver microsomes (RLM). The IC 50 shift experiments demonstrated that the inhibition of cariprazine by ponatinib was non-time-dependent. In addition, ponatinib was shown to inhibit cariprazine in a mixed manner (RLM) and a competitive manner (HLM), respectively. In the in vivo study, the co-administration of ponatinib resulted in a significant 0.35-fold increase in both AUC (0-t) and AUC (0-∞) for cariprazine, accompanied by a significant 0.25-fold decrease in the CL z/F . Furthermore, the metabolites desmethyl-cariprazine (DCAR) and didesmethyl-cariprazine (DDCAR) exhibited disparate increases in both AUC (0-t) and AUC (0-∞) . Molecular docking studies had demonstrated that both cariprazine and ponatinib could engage in hydrophobic interactions with residue PHE-304 on CYP3A4. Consequently, when ponatinib is employed in conjunction with cariprazine in a clinical setting, it is imperative to assess the efficacy and adverse effects, and adjust the dosage to attain the optimal efficacy.

Background and purpose: Ponatinib, a tyrosine kinase inhibitor (TKI) leads to hypertension; however, the mechanisms remain elusive. We aimed to investigate whether lysine acetyltransferase 7 (KAT7), a key regulator of cellular senescence that is closely associated with cardiovascular diseases, involves in ponatinib-induced hypertension. Methods and results: After administering ponatinib to Sprague–Dawley (SD) rats for 8 days, we measured blood pressure, vasodilation, and endothelial function using tail-cuff plethysmography, isometric myography, and the Total NO Assay kit, respectively. The results indicated that ponatinib increased blood pressure, impaired endothelium-dependent relaxation (EDR), and caused injury to endothelial cells in SD rats. Furthermore, PCR and Western blot experiments demonstrated an upregulation of KAT7 expression in rat mesenteric artery endothelial cells (MAECs) following ponatinib treatment. To further study the role of KAT7 in ponatinib-induced hypertension, we divided the SD rats into four groups: control, ponatinib, WM-3835 (a KAT7 inhibitor), and ponatinib plus WM-3835. Notably, WM-3835 administration significantly improved ponatinib-induced hypertension and EDR dysfunction in SD rats. Mechanistically, over-expression of KAT7 (OE-KAT7) in MAECs led to cellular senescence and inflammation, phenomena that were also observed in the mesenteric arteries of ponatinib-treated rats and in MAECs exposed to ponatinib. However, WM-3835 mitigated these detrimental effects in both in vivo and in vitro experiments. Additionally, both OE-KAT7 and ponatinib treatment induced H3K14 acetylation (H3K14ac), with OE-KAT7 also elevating the recruitment of the H3K14ac to the p21 promoter. Moreover, BAY 11-7085, a nuclear factor (NF)-κB inhibitor, potently alleviated the accumulation of IL-6 and IL-8, as well as endothelial cell senescence induced by ponatinib and KAT7 overexpression. Conclusion: Our data indicate that ponatinib-induced elevation of KAT7 led to endothelial cells senescence and inflammatory responses through H3K14 acetylation and NF-κB signaling pathway, subsequently caused vasotoxicity and hypertension.

Ethnopharmacological relevance Thrombus generation is one of the leading causes of death in human, and vascular endothelial dysfunction is a major contributor to thrombosis. Pheretima guillemi (Michaelsen), a traditional medicinal animal known as “Dilong”, has been utilized to cure thrombotic disorders for many years. DPf3, a group of functional proteins extracted from P. guillemi , has been characterized and identified to possess antithrombotic bioactivity via in vitro and ex vivo experiments. Aim of the study This study is aimed to investigate the vascular-protection activity and related mechanism of antithrombotic protein DPf3 purified from Pheretima guillelmi systematically. Materials and methods The antithrombotic activity and vascular endothelium protection effect of DPf3 was explored in vivo using ponatinib-induced vascular endothelial injury zebrafish thrombus model. Then, (hi) ox-LDL-induced HUVECs was applied to investigate the protection mechanism of DPf3 against the injury of vascular endothelium. In addition, TMT-based proteomics analysis was used to study the biomarkers, biological processes and signal pathways involved in the antithrombotic and vascular protective effects of DPf3 holistically. Results DPf3 exerted robust in vivo antithrombosis and vascular endothelial protection ability. DPf3 was identified to prevent HUVECs from damage by reducing ROS production, and to reduce monocyte adhesion by decreasing the protein content of adhesion factor VCAM 1. DPf3 was also observed to weaken the migration ability of injured cells and inhibit abnormal angiogenesis. The mechanism of DPf3's antithrombotic and vascular protective activity was mainly related to the regulation of lipid metabolism, energy metabolism, complement and coagulation system, ECM receptor interaction, MAPK signal pathway, etc. Conclusions This study demonstrates that DPf3 has strong antithrombotic and endothelial protective effects. The endothelial protective ability and related mechanisms of DPf3 provide a scientific reference for the traditional use of earthworms in the treatment of thrombosis.
