基督教聖經之智慧書導讀 :	Chronic hepatitis B remains a major global health burden with an unmet medical need, resulting in greater than one million annual deaths due to hepatitis B virus (HBV) associated liver complications, such as liver cancer and failure. Current treatment with nucleos(t)ide analogs suppresses viremia in most patients, but treatment cessation often results in viremia reoccurrence. As such, the development of novel anti-HBV therapies with new targets is required. We have identified the HBV ribonuclease H (RNase H) domain as an attractive drug target and previous work has determined RNase H inhibitors have sub-micromolar efficacy against HBV replication, but they lack the pharmacological evaluation that is required in preclinical studies for the identification of lead candidates. Previous work allowed us to eliminate compounds from the HID subgroup from lead candidate identification and here I evaluated the biological and pharmacological properties of compounds from the HPD, α-HT, and HNO chemotypes. I concluded due to a lack of improved efficacy and poor passive permeabilities of the HNOs, they should be excluded from the lead candidate identification. Additionally, after carrying 36 α-HTs through an in-depth, in vitro, drug discovery testing funnel, I concluded that they should be excluded from our drug discovery campaign because they are likely to cause drug-drug interactions and off-target effects at concentrations required to inhibit HBV replication. Finally, after assessing the anti-HBV efficacy and cytotoxicity of greater than 150 oxime HPDs, I evaluated 29 of them in an early- and late-stage drug discovery testing funnel. Notably, I identified two oxime HPDs, 1618 and 1620, that are safe, effective, and exhibit pharmacological properties similar to drugs on the market. As such, they warrant further in vivo evaluation as novel HBV RNase H inhibitors. Importantly, my in-depth evaluation of HBV RNase H inhibitors provided critical knowledge as we continue our efforts to identify compounds that could contribute to a functional cure for chronic hepatitis B.
