Design, synthesis, and anti-breast cancer activity evaluation of novel 3-cyanopyridine derivatives as PIM-1 inhibitors.

A novel series of cyanopyridines 7a-j were synthesized via a one-pot multicomponent reaction of arylidene 4 with ammonium acetate 5 and respective methylaryl/heterylketones 6a-j in ethanol using vanillin as a natural starting material. Moreover, the regioselective alkylation reaction was studied by the treatment of cyanopyridines 7a-f and 7j with CHI in the presence of KCO in DMF to afford O-methylcyanopyridines 8a-g (major) and N-methylcyanopyridines 9a-g (minor), whereas bipyridine 7h gave bipyridinium iodide salt 10. All of the designed cyanopyridines were evaluated as anti-breast cancer (MCF-7) cell lines via PIM Kinase inhibitory activity, and the results displayed that some of them showed high activities, especially compounds 7h and 8f, which showed excellent activities against MCF-7 with IC values of 1.

XRD/DFT, Hirshfeld surface analysis and molecular modelling simulations for unfolding reactivity of newly synthesized vanillin derivatives: excellent optical, NLO and protein binding efficiency.

New vanillin derivatives, namely, ethyl (4-formyl-2-methoxyphenoxy)acetate and 2-(4-formyl-2-methoxyphenoxy)--phenylacetamide , respectively, were synthesized and characterized by NMR (H and C), IR, mass spectra and confirmed by single-crystal X-ray analysis. Hirshfeld surface (HS) analysis was performed to probe intra- and intermolecular interactions and surface reactivity. 2D fingerprint plots (FP) were used to study the nature and percentage contribution of intermolecular interactions leading to the formation of the crystal unit.

Ketorolac-fluconazole: A New Combination Reverting Resistance in from Acute Myeloid Leukemia Patients on Induction Chemotherapy: In vitro Study.

Background And Objectives: is a significant source of morbidity and mortality for patients with acute myeloid leukemia (AML). Prolonged use of fluconazole as empirical antifungal prophylaxis in AML patients leads to overexpression of efflux pump genes that resulted in the emergence of azole-resistant species. Consequently, the introduction of a new strategy to improve the management of infections is an urgent need.

Tissue-based long non-coding RNAs "PVT1, TUG1 and MEG3" signature predicts Cisplatin resistance in ovarian Cancer.

Objectives: The current study aimed to investigate the potentiality of three lncRNAs "Plasmacytoma variant translocation 1(lnc-PVT1), Taurine upregulated gene type 1(lnc-TUG1) and Maternally expressed gene 3 (lnc-MEG-3)", to predict Cisplatin resistance in ovarian cancer (OC), in addition, to access their prognostic significance.

Methods: The expression level of lncRNAs were measured in 100 formalin-fixed paraffin-embedded tissue (FFET) samples of OC patients who were treated by Cisplatin-based chemotherapy using qPCR.

Results: The results showed that lnc_PVT1 was significantly upregulated by 2.

Pfeifferinella sp. (Pfeifferinellidae, Apicomplexa) infecting the fresh water snail Pirenella conica light and electron microscope studies.

Coccidian oocysts were proved to be found in 70 of 100 collected Pirenella conica snails, with a natural infection of 70%. It was observed that, Pfeifferinella sp. was transferred between hepatopancreas and small intestine of snail.
