    Article Title: Evaluation of the near infrared compound indocyanine green as a probe substrate of p-glycoprotein.
    Article Snippet: The efflux transporter P-glycoprotein (P-gp) affects the pharmacokinetics of many drugs.. Currently used methods for characterization of P-gp’s functional activity in vivo involve the use of radiolabeled substrates, are costly, and are technically demanding.. Our objective was to evaluate whether the FDA-approved near-infrared compound indocyanine green (ICG) can be used as a probe substrate of P-gp.

    Changes in P-glycoprotein (P-gp) transport activity in brain capillaries ( N = 15–20 per data point) from six rats treated with erastin. ( A ) Representative confocal fluorescent and DIC images of brain capillaries after a 60-min incubation with 2.0 μM NBD-CSA; note the high luminal fluorescence in the control capillary and ( B ) decreased luminal fluorescence in capillaries exposed to 10.0 μM <t>PSC833</t> (Scale bars, 10 μm). Representative confocal images of the luminal fluorescence (LF) from ( C ) male and female brain capillaries associated with P-glycoprotein (P-gp) transport activity at increasing doses of erastin in brain capillaries of SD rats. Bar graphs of P-glycoprotein transport activity determined by LF in ( D ) male and ( E ) female capillaries. Graphs of LF measuring P-glycoprotein (P-gp) transport activity in male ( F ) and female ( G ) capillaries (capillary N = 15–20 per experimental data point) exposed to 0.001 μM erastin over time. Dotted red line denotes multiple comparison. Significance is as compared to control unless otherwise specified: * p < 0.05, ** p < 0.01, *** p < 0.001.
