BV6 is an antagonist of cIAP1 and XIAP, members of the inhibitors of apoptosis (IAP) family.
体外研究
HCC193 has an IC50 of 7.2 μM in MTS assays, while H460 cells are not reduced to 50% viability even with 30 μM BV6 treatment. Administration of 1 μM BV6 to HCC193 cells induces complete depletion of cIAP1 levels at 1 hour post-treatment, while a decrease in XIAP levels is not seen until 24 hours following addition of drug. Similarly, 5 μM BV6 fully depletes cIAP1 at 1 hour and begin to reduce XIAP at 24 hours in H460 cells. In parallel findings, cIAP1 levels are decreased in response to a small dose of 0.25 μM BV6 in both cell lines, whereas trace amounts of XIAP are still present at 5μM BV6. HCC193 cells demonstrates noticeable cleaved caspase-3 levels beginning 12 hours post-incubation with 1μM BV6, and cleaved caspase-3 levels continued to increase in a time-dependent manner over 48 hours. Treatment of HCC193 cells with 1 μM BV6 for 24 hours causes a significant survival curve shift in HCC193 cells relative to DMSO-treated cells, with a DER=1.38 (p<0.05). BV6 (2 and 5 µM) significantly represses BrdU incorporation in ectopic and eutopic (disease-free and myomas) ESCs. An ~30% decrease of BrdU incorporation is observed in both groups after treatment with 5 µM BV6.

Murine cIAP-1, cIAP-2 and XIAP expressions are clearly observed in the cytoplasm of both epithelial and stromal cells of implants, whereas Survivin is mainly expressed in the nuclei BV6 treatment for 4 weeks attenuated the intensity of IAPs expression. The size of lesions range from ~2 to 7 mm in diameter. The monolayer epithelial cell lining of the cyst is shown. After immunohistochemical staining, cytokeratin and vimentin are positively stained, whereas calretinin is negative. After BV6 treatment for 4 weeks, the total number of lesions (4.6 versus 2.8/mouse), the average weight (78.1 versus 32.0 mg/mouse) and the surface area (44.5 versus 24.6 mm/mouse) of lesions are significantly less than in the controls. In the endometrial gland epithelia or stroma, the percentage of Ki67-positive cells decreases after BV6 treatment.
