Liquid Biopsy in Gynecological Cancers
2017
Gynecological cancers originate in woman’s reproductive organs, including ovarian, uterine or endometrial, cervical, vulvar, and vaginal cancers. These tumors are a leading health problem for women accounting for more than 20% of new cases and cancer-related deaths worldwide. Gynecological cancers are characterized by an aggressive biological behavior with a clinical presentation often in advanced stage of disease. This chapter will focus on the potential role of the novel molecular approaches based on liquid biopsy in detecting occult disease, monitoring the progression and identifying treatment-resistance in gynecological cancer patients. The ability to detect circulating tumor DNA (ct-DN…
Spectroscopic, crystal structural, theoretical and biological studies of phenylacetohydrazide Schiff base derivatives and their copper complexes
2020
Two phenylacetohydrazide Schiff base derivatives: N’-(1-(2-hydroxyphenyl)ethylidene)-2-phenylacetohydrazide, HL1, and N’-((1-hydroxynaphthalen-2-yl)methylene)-2-phenylacetohydrazide, HL2, were synthesized. HL1 dimerizes in presence of HCl, probably via radical mechanism to give (2,2’-((1E)-hydrazine-1,2-diylidenebis(ethan-1-yl-1-ylidene))diphenol (DIM). Thermal reactions of Cu(II) ions with the two Schiff base ligands resulted in formation of the binuclear complexes [(CuL1)2] and [(CuL2)2]. The stoichiometry and structures of the reported compounds were investigated by several spectroscopic and analytical techniques. The structure of the HL1 ligand and its complex [(CuL1)2] as well as the D…
