Description: BMH-21 is a potent small molecule DNA intercalator. BMH-21 binds ribosomal DNA and inhibits RNA polymerase I (Pol I) transcription. BMH-21 does not cause phosphorylation of H2AX, a key biomarker activated in DNA damage stress. BMH-21 effects on the nucleolar stress response were independent of major DNA damage associated PI3-kinase pathways, ATM, ATR and DNA-PKcs. BMH-21 is a chemically unique DNA intercalator that has high bioactivity towards Pol I inhibition without activation or dependence of DNA damage stress. The findings also show that interference with DNA and DNA metabolic processes can be exploited therapeutically without causing DNA damage.

Biological target: BMH-21 is a DNA intercalator that inhibits RNA polymerase I (Pol I) transcription and possesses anticancer activity.
In vitro activity: To evaluate the inhibitory effect of BMH-21 on SKOV3, Bel-7402 and HeLa cell viability, cells were treated with increasing doses of BMH-21 for 24 h and cell viability was determined by an MTT assay. BMH-21 treatment decreased the viability of SKOV3, Bel-7402 and HeLa cells in a dose-dependent manner (Fig. 1A, E and F). Based on MTT results, we treated SKOV3 cells with increasing doses of BMH-21 (1, 2 and 4 µM) for 24 h. The changes in SKOV3 cell morphology were examined using an inverted optical microscope. The cells treated with BMH-21 became fragmented and round when compared with control cells (Fig. 1B). To examine the distribution of cell cycle progression, the effect of BMH-21 in various cell cycle phases was confirmed using flow cytometry. BMH21 resulted in a marked increase in the percentage of cells blocked at G2/M phase (Fig. 1C and D). These findings indicated that BMH-21 effectively inhibited cancer cell viability and suggested that BMH-21 induced cell death.

In vivo activity: To further understand the role of BMH-21 in prostate tumorigenesis in another preclinical prostate cancer model, the Hoxb13MYC|Hoxb13-Cre|Ptenfl/fl (BMPC) mouse prostate cancer model in which the development of aggressive tumors is detected at 16 to 20 weeks of age was used The BMPC mice develop castration resistance and lose expression of AR around 20 weeks of age. As observed in Figure 7C, cells isolated from BMPC tumors31 had negligible AR expression. BMPC-1 cells were then treated with BMH-21 for 48 hours. A robust reduction in their growth (Figure 8A) was observed. To explore the potential of BMH-21 to repress tumor growth on these established tumors, treatments were initatied using an intraperitoneal administration of BMH-21 at 50 mg/kg at the age of 20 weeks and followed individual mice until the palpable tumor burden reached a euthanasia endpoint (Figure 8B). There was no statistical difference between the survival of vehicle and BMH-21 treated mice (Figure 8C). However, it was observed that BMH-21 treatment significantly reduced the tumor burden as measured by urogenital block size compared to vehicle control (Figure 8C). Histological analysis of the urogenital block also demonstrated a reduction in invasion compared to vehicle control (Figure 8D and 8E). The findings from this genetic mouse model suggest that BMH-21 may be a potential first-in-class molecule that is able to inhibit prostate tumorigenesis.
