NTCP Substrate pharmacophore

What is it about?

We developed a common feature pharmacophore for human NTCP from 18 native bile acids and 2 bile acid conjugates. This was used to show FDA approved drugs could map to it. The modeling was combined with experimental work to show in vitro transport for Irbesartan and Losartan.

Why is it important?

NTCP is a target for hepatitis B virus entry, inhibition can prevent infection. In this study we focused on deriving a substrate pharmacophore. This was demonstrated to reliably predict FDA drugs that could map to it and were substrates in vitro. This could be used for selecting compounds with improved uptake by targeting this transporter.

A useful example of how a small training set can be put to use for prediction and model validation. This provides a foundation for future model development and efforts to understand the SAR of NTCP.
