The rattans of Spatholobus suberectus Dunn are a traditional Chinese medicine activating blood circulation and removing stasis. They have often been used for the traditional Chinese medicinal treatment of breast cancer in modern China. In this study, four novel isoflavanes (1–3 and 5) and four known analogues (4 and 6–8) were isolated from an ethanolic extract of the rattans of S. suberectus. Their structures were elucidated by extensive spectroscopic analyses and electronic circular dichroism studies. MCF-7 and MDA-MB-231 human breast cancer cell lines were used to evaluate the cytotoxic effects of the isolates. Interestingly, compounds 1 and 2 only inhibited the proliferation of MCF-7 cells, while compound 6 showed a selective cytotoxicity against MDA-MB-231 cells. However, compound 4 had significant cytotoxicity against both MCF-7 and MDA-MB-231 cell lines.

Two human breast cancer cell lines (MCF 7 and T 47D) possess calcitonin-responsive adenylate cyclase systems. Suspended cells of both lines specifically bound 125I-labelled salmon calcitonin with mean dissociation constants of 1.7 nM (MCF 7) and 1.4 nM (T 47D); mean receptor numbers were 5300 and 24400 per cell respectively. Measurement of specific binding to MCF 7 cells was obscured by rapid and substantial degradation of the labelled hormone. Degradation of 125I-labelled salmon calcitonin: (i) was of high capacity; (ii) lacked the specificity displayed by 125I-labelled salmon calcitonin binding to the same cells; and (iii) was not related to binding since cell incubation supernatants retained full degrading activity. The degrading activity was inhibited by corticotropin (1-24)-tetracosapeptide, insulin and bacitracin. Inclusion of bacitracin in the incubation resulted in apparently fewer numbers of lower affinity receptors on MCF 7 cells, whereas these parameters were identical to T 47D cells incubated in the presence or absence of bacitracin. Eel [2-aminosuberic acid 1,7]-calcitonin was resistant to proteolysis in the presence of either cell line. Analysis of hormone-receptor interactions with calcitonin-responsive cells should take account of potent calcitonin-degrading activities in some cell lines.
