Antitumor Activity, Mechanisms of Action and Phytochemical Profiling of Sub-Fractions Obtained from Planch. (Fabaceae): A Medicinal Plant from Galicia (Spain).

The plant kingdom serves as a valuable resource for cancer drug development. This study explored the antitumor activity of different sub-fractions (hexane, dichloromethane and methanol) of (gorse) methanol extract in glioblastoma (U-87MG and U-373MG) and neuroblastoma (SH-SY5Y) cell lines, along with their phytochemical profiles. Cytotoxicity was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and lactate dehydrogenase (LDH) assays, and cell cycle arrest and apoptosis were assessed through flow cytometry and by measuring reactive oxygen species (ROS) and protein expression levels.

Phytochemical Analysis and Antiproliferative Activity of Planch. (Fabaceae), a Medicinal Plant from Galicia (Spain).

The genus comprises thirteen accepted species of perennial shrubs in the family Fabaceae. In Galicia (Spain) many of these are considered spontaneous colonizing species, which are easy to establish and maintain. Among them, Planch.

Antitumor activity of copper(II) complexes with Schiff bases derived from N'-tosylbenzene-1,2-diamine.

The electrochemical oxidation of anodic metal copper in a solution of the ligands N-[(5-tert-butyl-2-hydroxyphenyl)methylidine]-N'-tosylbenzene-1,2-diamine [HL] and N-[(3,5-di-tert-butyl-2-hydroxyphenyl)methylidine]-N'-tosylbenzene-1,2-diamine, [HL] afforded homoleptic [CuL] compounds or solvate [CuLS] complexes. The addition to the electrochemical cell of coligands (L') such as 2,2'-bipyridine (2-bpy), 4,4'-bipyridine(4-bpy) or 1,10-phenanthroline (phen) allowed the synthesis, in one step, of heteroleptic [CuLL'] compounds, namely [CuL(HO)] (1), [CuL(2,2'-bpy)]⋅CHCN (2), [CuL(phen)]·HO (3), [CuL(4,4'-bpy)] (4), [CuL(CHOH)] (5), [CuL(2,2'-bpy)] (6), [CuL(phen)] (7) and [CuL(4,4'-bpy)] (8). The crystal structures of both ligands, HL, HL, and those of the complexes (2), (4), (5), (6) and (7) have been determined by X-ray diffraction techniques.
