Study of the antitumor activity of 2-(1,1-dimethyl-1H-benzo[e]indolin-2-yl)-5,6,7-trichloro-1,3-tropolone in combination with temozolomide on the U87 glioblastoma model in vivo

Abstract

This study is aimed to evaluate the antitumor efficacy of 2-(1,1-dimethyl-1H-benzo[e]indolin-2-yl)-5,6,7-trichloro-1,3-tropolone in combination with temozolomide (TMZ) in subcutaneous xenografts of U87 glioblastoma cells in Balb/c Nude mouse line. The findings revealed that combination therapy resulted in a greater reduction in tumor volume and relative tumor mass compared to TMZ monotherapy, with TGI rates of 70.27% versus 66.72%, respectively. Histological analysis confirmed marked cellular dystrophic changes in tumors subjected to combination therapy. These results suggest a potential synergistic interaction between tropolone and temozolomide, which may enhance the efficacy of glioblastoma treatment.
