Abstract
Malignant gliomas are common and aggressive brain tumours in adults. The rapid proliferation and diffuse brain migration are the main obstacles to successful treatment. Here, we show 25(R)-spirostan-3beta,5alpha,6beta,19-tetrol, a polyhydroxy steroid, is capable of suppressing proliferation and migration of C6 malignant glioma cells in a concentration-dependent manner. The compound 25(R)-spirostan-3beta,5alpha,6beta,19-tetrol was synthesised by seven steps starting from diosgenin in 8.55% overall yield. The structures of the synthetic compounds were characterised by infrared (IR), (1)H nuclear magnetic resonance (NMR), (13)C NMR spectra and EA.
