Resumen
The reduction of parasitism tissue upon treatment with two lignano lactones, namely (-)- cubebin (CUB) and (-)-hinokinin (HNK), was evaluated in the chronic phase of Chagas` disease by quantifying the enzyme beta-galactosidase expressed by the CL B5 clone strain of Trypanosoma cruzi. Tissue karyometry was also performed. Treatment with the assessed lignans led to a larger reduction in parasitism tissue in all evaluated organs, compared with benznidazole (BZN). Oral treatment with CUB or HNK was more effective. Karyometry results demonstrated that the infected control animals had increased nuclear area compared with uninfected controls, indicating cellular hypertrophy. Results also revealed that use of CUB or HNK was able to significantly prevent this increase, and a slight decrease in the nuclear area was observed, compared with mice treated with BZN. Taken together, these data demonstrate that CUB and HNK could be considered as potential compounds for the development of new drugs for treatment of Chagas` disease.
