Abstract
Benign prostatic hypertrophy (BPH) is an intractable chronic inflammatory disease. We studied the efficacy of two ellagitannins, namely camptothin B (1) and cornusiin A (2) that were isolated from Cornus alba (CA) for the treatment of BPH, which is a common health issue in older men. The ellagitannins (1 and 2) were evaluated on its inhibitory activities of the enzyme 5α-reductase and tumor necrosis factor (TNF)-α, its interleukin (IL)-1β, IL-6, and IL-8 production, and its anti-proliferation and apoptosis induction in prostate cells that show hypertrophy (RWPE-1 cell). In inhibition of 5α-reductase, the ellagitannins (1 and 2) showed potential effects, compared to the positive control, finasteride. In the case of IL-1β, IL-6, IL-8, and TNF-α, 1 and 2 showed good inhibitory effects as compared to the control group treated with LPS. The ellagitannins (1 and 2) were also shown to inhibit proliferation of, and induce apoptosis in, the RWPE-1 cell. These results suggest that the ellagitannins (1 and 2) may be good candidates for the treatment of BPH.
