Table 1.

Relationship between charge state, lipophilicity and hERG inhibition

Target upper limits of logD7.4 and ClogP to estimate >70% of compounds achieve a hERG IC50 of greater than 10 μM
Acids Bases Neutrals Zwitterions
logD7.4 >4 1.4 3.3 2.3
ClogP >9 1.9 1.9 4.4

From ref 36. logD7.4 and ClogP upper limits to avoid hERG inhibition for various charge states.
