How to use

In Vitro:

DRF-1042 demonstrates superior lactone stability and good in vitro anticancer activity against a panel of human cancer cell lines including multi-drug resistance (MDR) phenotype.

In Vivo:

In clonogenic assay against murine, canine and human bone marrow cells, DRF-1042 treatment shows less mylosupression that supports the possibility of protracted dose schedule in both experimental and clinical studies.
