Opis

Opis ogólny

A cell-permeable 2′-benzyloxy griseofulvin derivative that displays enhanced mammalian cancer-selective toxicity (IC₅₀ ≤2, ≤4, ≤12, and ≥30 µM against panels of leukemia, myeloma, solid tumors, and non-malignant cell lines, respectively), but little antifungal activity, by activating spindle-assembly-checkpoint (Pos. vs. Neg. RubR1 staining of metaphase PC-3 kinetophores with or without 24 h 0.75 µM GF-15 treatment) without affecting microtubule kinetochore attachment (Neg. Mad2 staining of metaphase PC-3 kinetophores with or without GF-15). Cancer cells are reported to undergo multipolar (MP) mitosis with normal or supernumerary centrosomes (Aberrant vs. declustered, respectively) in the presence of GF-15 (%Declustered / %Aberrant MP mitotic cells among all anaphase cells = 5.6/&lt0.5, 10/3.9, 16/18, 28/30, respectively, in PC-3 cultures treated with 0, 0.375, 0.75, or 1.5 µM GF-15 for 24 h), resulting in subsequent apoptotic cell death. Shown to retard OPM2 myeloma- and HT29 colon cancer-derived tumor expansion in mice (by 49% and 56%, respectively at the end of 2-wk treatment; 10 i.p. dosages at 20 mg/kg/day in 2 weeks) in vivo. Based on stability data obtained with its p-iodobenzyl analogue, GF-15 half-life is expected to be least 48 h in cultures.
