KR31173
KR31173 is an AT1 antagonist with an IC50 of 3.27 nM. KR31173 can be used as a positron emission tomography (PET) tracer after being labeled with 11C isotope. KR31173 shows promising biodistribution and pharmacological properties in mice. KR31173 selectively binds to organs known to contain a high density of AT1 angiotensin receptors in CD-1 mice.

-
Animal Model:Male CD-1 mice were injected via the tail vein with 19.1 MBq (517 μCi, 1.45 μg/kg) of [11C] KR31173 10 min after KR31173 administration[1].
-
Dosage:1 mg/kg
-
Administration:i.v., once and then collected blood sample, and measured organs weight and their radioactivity 60 min after [11C] KR31173 administration.
-
Result:Had high initial liver uptake which rapidly washes out over 30 minutes following by subsequent accumulation in adrenal glands and kidneys after 30 minutes, with tissue-to-blood ratios generally exceeding 10:1.
Significantly inhibited the uptake of [11C] KR31173 in the adrenal glands (91%), kidneys (90%), lungs (88%), heart (92%) and livers (50%).
