Abstract
![]()
MMV390048 (1) is a clinical compound under investigation
for antimalarial activity. A new synthetic route was developed which
couples two aromatic fragments while forming the central pyridine
ring over two steps. This sequence takes advantage of raw materials
used in the existing etoricoxib supply chain and eliminates the need
for palladium catalysts, which were projected to be major cost-drivers.

Abstract
The effects of the CF2H moiety on H-bond (HB) acidity and lipophilicity of various compounds, when attached directly to an aromatic ring or to other functions like alkyls, ethers/thioethers, or electron-withdrawing groups, are discussed. It was found that the CF2H group acts as a HB donor with a strong dependence on the attached functional group ( A = 0.035-0.165). Regarding lipophilicity, the CF2H group may act as a more lipophilic bioisostere of OH but as a similar or less lipophilic bioisostere of SH and CH3, respectively, when attached to Ar or alkyl. In addition, the lipophilicity of ethers, sulfoxides, and sulfones is dramatically increased upon CH3/CF2H exchange at the α position. Interestingly, this exchange significantly affects not only the polarity and the volume of the solutes but also their HB-accepting ability, the main factors influencing log Poct. Accordingly, this study may be helpful in the rational design of drugs containing this moiety.
