    • 10e Their values of VCR accumulation with 1 were 419% of control and 147% of verapamil at 1 μg/mL and smaller than the values reported by us probably because of the purity of their sample.

    • 12,13 Effective concentration is high enough and differential growth is recognized. Since the results of COMPARE of 1 are negative, 1 is suggested to be a new type of anticancer agent.

    • 1H NMR spectrum of 11 showed that the configurations of 13β- and 5α-hydroxyl groups were equatorial (dd, J = 9.5 and 3.5 Hz) and axial (br t, J = 2.5 Hz), respectively. The 5α(ax)-hydroxyl group is more hindered than the 13β(eq)-hydroxyl group.
