The Nature of Nanodisc Lipids Influences Fragment‐Based Drug Discovery Results

Chemical Biology and Drug Design

Fragment-based drug discovery (FBDD) was applied to cytochrome P450 3A4 reconstituted in Nanodiscs (NDs) with various lipid compositions. The choice of ND lipid influenced drug membrane interactions and fragment hit rates, demonstrating the critical role of the membrane environment in fragment screening for membrane proteins.

Advancements in hit identification for membrane protein drug discovery

Drug Target Review

Fragment-based screening (FBS) has emerged as a powerful tool for discovering novel lead compounds, especially for challenging targets like the Adenosine A2a receptor. The Adenosine A2a receptor was expressed in insect cells using a baculoviral expression system. References Sun D, et al.

COVID-19 stuff

Molecular Design

I’m currently in Trinidad so I’ll share a photo from Berwick-on-Sea, on Trinidad's north coast (and the correspondence address for a two [ K2017 | K2019 ] of my more controversial articles). Martin and I wrote a short article which we uploaded to figshare and Martin also did a blog post.

SARS-CoV-2 main protease. Crowdsourcing, peptidomimetics and fragments

Molecular Design

The binding mode observed for 1 is shown below in Figure 1 and it’s likely that the groove region will need to be more fully exploited (this article will give you an idea of the sort of thing I have in mind) in order to achieve acceptable potency if the aldehyde warhead is replaced by nitrile. by forming a ring). by forming a ring).

Tom Lehrer's guide to design of SARS-CoV-3 main protease inhibitors for treatment of COVID-32

Molecular Design

In the fourth of his rules for air fighting , ‘Sailor’ Malan (readers may also be interested in his insights into fragment screening library design ) asserts that “height gives you the initiative” which can be adapted for drug design as “affinity gives you the initiative”.

SARS-CoV-2 Protease Inhibitors: An Attractive Approach for Treating COVID-19

PerkinElmer

The second virtual screen focused on optimization of a hit from a previous crystallographic fragment screen. Fragment-to-lead optimization was guided by searches in a library of millions of compounds combined with docking screens to select the best candidate.

Why fragments?

Molecular Design

Paramin panorama Crystallographic fragment screens have been run recently against the main protease (at Diamond ) and the Nsp3 macrodomain (at UCSF and Diamond ) of SARS-Cov-2 and I thought that it might be of interest to take a closer look at why we screen fragments.
