Biological Activity
Atrimustine (Bestrabucil), a conjugate of chlorambucil and β-estradiol benzoate, has high affinity for tumor cells and enhances the antitumor activity of chlorambucil[1].The effect of Atrimustine (Bestrabucil), a benzoate of an estradiol-chlorambucil conjugate, is examined on the production of growth factor(s) by Shionogi carcinoma 115 (SC-115) cells, an androgen-responsive cultured cancer cell line. At Atrimustine concentrations of 100 nM-10 μM, concentration-dependent inhibition of growth factor production by SC-115 cells can be demonstrated by 3H-thymidine uptake assay[2].

Protocol
In the culture system containing 10 nM Testosterone, Atrimustine (Bestrabucil) exhibits a statistically significant inhibition of SC-115 cell growth at concentrations of 10 μM and 1 μM. Mixtures of Estradiol and Chlorambucil also significantly inhibit the growth of SC- 115 cells at concentrations of 1 μM and 100 nM. The inhibitory effect at day 7 of culture is regarded as similar for 10 μM Atrimustine and 1 μM of the mixture. At 10 μM, Atrimustine inhibits the growth of SC-115 cells to the sarve degree as the control culture without Testosterone and this concentration of Atrimustine is taken as the IC50. Thus, in experiment 2, 10 μM Atrimustine is used in the CM of SC-115 cells to study the inhibition of growth by Atrimustine [2].
