We performed a screening program to identify telomerase inhibitors from our drug source obtained from fungus fermentations, and found that two compounds, CRM646-A and thielavin B, inhibited telomerase activity at doses of 3.2 and 32 microM, respectively. These compounds also inhibited the activity of viral reverse transcriptase at almost the same dose levels which inhibited telomerase activity.
