The synthesis of 1,4,7,10-tetraazacyclododecanes with acetylsalicylic side arm as potential cobalt(II) fluorophores.
PublicationMonoacylowe pochodne 1,4,7,10-tetraazacyklododekanu otrzymano w bezpośredniej reakcji cyklenu z chlorkiem kwasu salicylowego, jak również przy użyciu trichronionego cyklenu. Monoacylową pochodną wykorzystano następnie w reakcji z fosforynem etylu otrzymując difunkcyjny związek. Otrzymane ligandy zbadano spektrofotometrycznie. Obydwa ligandy oddziaływują selektywnie z jonami Co(II), tworząc kompleksy o stechiometrii 2:1 i 1:1 (ligand:metal).

The potential interaction of environmental pollutants and circadian rhythm regulations that may cause leukemia
PublicationTumor suppressor genes are highly affected during the development of leukemia, including circadian clock genes. Circadian rhythms constitute an evolutionary molecular machinery involving many genes, such as BMAL1, CLOCK, CRY1, CRY2, PER1, PER2, REV-ERBa, and RORA, for tracking time and optimizing daily life during day-night cycles and seasonal changes. For circulating blood cells many of these genes coordinate their proliferation,...
