Synthesis, Characterization, and Anticancer Activities of Pyrogallol-Based Arylspiroborates

Arylspiroborate salts derived from pyrogallol, gallic acid, and propyl gallate have been prepared and characterized fully, including an X-ray diffraction study for the tetrabutylammonium gallic acid complex 4. The tetrabutylammonium salts were examined for their potential anticancer activities against renal cell carcinoma (RCC) cell lines, using NBu4[Bcat(2)] (cat = catecholato) as a control.
