Anticancer potential of poly(2-aminobenzoic acid)-blend-Aloe vera against the human breast cancer cell line MDA-MB-231

Breast cancer in women is amongst the most significant concerns from time immemorial in the field of oncology. This study proposes an anticancerous polymeric material based on an electroactive substituted polyaniline blend, poly(2-aminobenzoic acid)-blend-Aloe vera (PABA/AV) synthesized by the emulsion polymerization method. The structural, thermal, and morphological characteristics determined using FT-IR and UV-Visible Spectroscopy, XRD, TGA, DTA, and SEM-EDX validated the thermally stable, semi-crystalline, emeraldine salt structure. The material is semi-conducting, and the electrical conductivity measured is 1.86 × 10−3 S/cm. It shows bactericidal efficacy against Enterococcus faecalis at a minimum inhibitory and minimum bactericidal concentration of 50 μg/mL. The radical cations in the emeraldine polymer chain reduce the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical and exhibit a significant % of DPPH scavenging (89.85%) at 20 μL. The polymer blend is active against the human breast cancer cell line MDA-MB-231 and causes 78.65% cytotoxicity at a concentration of 125 μg/mL. The synergistic effect of the ancient healing Aloe vera plant and the electroactive biocompatible poly(2-aminobenzoic acid) certainly opens up new developments in the field of cancer therapy.
