Lipophilicity profiling of anthracycline antibiotics by microemulsion electrokinetic chromatography–effects on cardiotoxicity and endotheliotoxicity

Abstract

Accurate profiling of the lipophilicity of amphoteric compounds might be complex and laborious. In the present work the lipophilicity of 12 anthracycline antibiotics–four parent drugs: doxorubicin, daunorubicin, epidoxorubicin, and epidaunorubicin and eight novel formamidyne derivatives with attached morpholine, hexamethylenoimine or piperidine rings–was determined based on novel approach using MEEKC. In the second stage, lipophilicity was correlated with anthracycline toxicity towards two cell lines. In rat cardiomyoblast cell line (h9c2) a significant correlation between the logP and toxicity was found. The anthracycline lipophilicity was not correlated with toxicity towards the endothelial hybrid cell line (EAhy.926). In conclusion, the lipophilicity of anthracyclines seems to determine their toxicity towards cardiomyoblasts but not on endothelial cells, suggesting a different mechanism of anthracyclines intercellular transport or extrusion in cardiomyoblast and endothelial cells.

Translational Proteomics Analysis of Anthracycline-Induced Cardiotoxicity From Cardiac Microtissues to Human Heart Biopsies

“…The lipophilic ability could be an underlying factor that leads to the differences in protein profiles, in which IDA has higher lipophilicity than its parent molecule, daunorubicin ( Matyszewska, 2020 ), while daunorubicin has higher lipophilicity than DOX ( Matyjaszczyk-Gwarda et al, 2019 ). Specially, a rat cardiomyoblast study showed the inverse correlation between the lipophilicity of ANT analogs and their toxicity ( Matyjaszczyk-Gwarda et al, 2019 ).…”

The way forward in multi-omics data analyses

“…The lipophilic ability could be an underlying factor that leads to the differences in protein profiles, in which IDA has higher lipophilicity than its parent molecule, daunorubicin [77], while daunorubicin has higher lipophilicity than DOX [78]. Interestingly, a rat cardiomyoblast study showed the inverse correlation between the lipophilicity of ANT analogs and their toxicity [78].…”
