MK-571 sodium (L-660711 sodium salt) is a selective, orally active antagonist of the CysLT1 receptor. MK-571 sodium is a multidrug resistance protein-2 (ABCC2, Mrp2) inhibitor used to demonstrate the role of Mrp2 in the cellular efflux of drugs, xenobiotics, and their conjugates. MK-571 sodium can inhibit the synthesis of K-4′-O-GlcA (19.7 μM). MK571 dose-dependently inhibits the intracellular biosynthesis of all flavonol sulphates and glucuronides by Caco-2 cells. MK-571 sodium significantly inhibits phase-2 conjugation of kaempferol by cell-free extracts of Caco-2, and production of kaempferol-4′-O-glucuronide was competitively inhibited. In addition to inhibiting MRP2, MK571 is a potent inhibitor of enterocyte phase-2 conjugation.

Ibutilide Fumarate (U70226E) is the fumarate salt form of ibutilide, a class III antiarrhythmic agent.

This results in prolongation of atrial and ventricular action potential duration and refractory periods. Ibutilide slightly decreases the sinus rate and atrioventricular (AV) conduction and produces a dose-related prolongation of the QT interval.

Becatecarin is a water-soluble, diethylaminoethyl analog of the antineoplastic antibiotic rebeccamycin. It intercalates into DNA, stabilizing the DNA-topoisomerase complex. This results in the potent catalytic inhibition of both topoisomerases I and II, initiating DNA cleavage and apoptosis. Becatecarin, alone or in combination with other compounds, has anti-cancer as well as myelosuppressive effects in vivo. It is also a transport substrate of the ATP-binding cassette (ABC) transporter ABCG2.

MsbA-IN-6 is a potent antibiotic and inhibitor of the gram-negative ATP-binding cassette (ABC) transporter MsbA, an essential protein for transporting lipopolysaccharide across the inner bacterial membrane. It exerts a bactericidal effect on Escherichia coli by inhibiting the ATPase and transport activity of MsbA, while retaining efficacy against multidrug-resistant clinical strains [1] [2].

st-Ht31, a cell-permeable stearated peptide derived from the amphipathic helix domain of A-kinase anchoring proteins (AKAPs), effectively binds protein kinase A (PKA), impacting PKA's cellular interactions without altering its activity.
