ABCG2-IN-4 (Compound K31) is an orally active ABCG2 inhibitor that reduces the release of Protoporphyrin IX (PPIX) from red blood cells into the plasma and prevents phototoxicity. In mouse models, ABCG2-IN-4 also demonstrates anti-inflammatory and antioxidant properties.

ABCG2-IN-1 (compound K2), an analog of Ko143, is an orally active inhibitor of ABCG2 with an IC50 of 0.13 μM, demonstrating favorable oral pharmacokinetics in mice and showing promise for further research [1].

ABCG2-IN-2 is a potent inhibitor of ABCG2, showing favorable oral pharmacokinetic profiles in mice, and is applicable for investigating tumor multidrug resistance (MDR) and erythropoietic protoporphyria (EPP) [1].
