Abstract Epigenetic regulation plays an important role in cell fate reprogramming. Here, we found that inhibitors of epigenetic modifiers, including VPA, TSA, and 5‐Aza‐2'‐deoxycytidine, can induce phenotypic transformation from Jurkat cells into B‐cell‐like cells. When Jurkat cells were treated with 5‐Aza combined with VPA, B cell and stem cell marker

Hypolipidemic influence of CETZ.2HCl‐(H1‐antihistamine) metal‐complexes on “C57Bl/6‐mice” fed high‐fat‐diet. ABSTRACT New Cd(II), Zn(II), and Cu(II) chelates with cetirizine.2HCl (CETZ.2HCl) in incidence of 1,10 phenanthroline monohydrate (Phen.H2O) were synthesized in search of new biologically active compounds.

Photoinduced Hydrogen Evolution Catalyzed by Co(II) Complexes of N5‐Donor Ligands
Cobalt(II) complexes of three related pentadentate ligands have been investigated as photoelectrochemical catalysts for proton reduction/hydrogen gas evolution in the presence of ruthenium, iridium, or copper‐based photosensitizers. Potential mechanisms for hydrogen evolution have been investigated by time‐resolved transient absorption spectroscopy and
