MLC as an effective tool in the prediction of human intestinal absorption

stimation of human intestinal absorption is very important especially for orally administered pharmaceutical compounds
with poor solubility. Therefore in pre-formulation studies the extent of drug absorption must be determined for new drug
entities (NDE). The use of animals has been the most abundant method used in pre-formulation studies for determination
of pharmacokinetics, especially, the rate and extent of intestinal absorption of pharmaceutical compounds. In this work the
use of biodetergent based micellization with a form of chromatography known as micellar liquid chromatography (MLC)
has been successful in the determination of human intestinal absorption. Bile salts were used as a mobile phase in the MLC
chromatographic method to provide an environment more closely simulating the human intestinal environment. In this
method intestinal absorption was successfully predicted by the use of a group of model compounds through measurement
and calculation of the partition coefficient, P
mw
. A series of model drugs were prepared in the corresponding mobile phase
concentration and injected into the chromatographic system with capacity factors obtained by analysis of the retention data
recorded for the model drugs used. Experimentally determined partition coefficients were used alongside other molecular
descriptors in the modeling of human intestinal absorption (% HIA) using multiple linear regression. The obtained model
confirmed the ability of MLC to predict human intestinal absorption (% HIA) (R2=0.86 and R2Pred.=0.75).
