| In Vitro | OPC-28326 enhances endothelial tube formation and promotes microvessel growth. OPC-28326 induces phosphorylation of eNOS and Akt in HAECs in a dose dependent-manner, while it does not affect total amounts of eNOS and Akt[1]. OPC-28326 (1-100 μM) and yohimbine (10-1000 nM) causes a rightward shift in the concentration-response curve of clonidine[2]. |
| In Vivo | OPC-28326 augments blood flow recovery in murine hindlimb ischemia. OPC-28326 significantly increases the number of histologically detectable capillaries in the ischemic leg. OPC-28326 has no beneficial effects on blood flow recovery in eNOS−/− mice[1]. OPC-28326 (3-30 mg/kg, i.v.) and yohimbine causes dose-dependent rightward shift in the pressor dose-response curve induced by B-HT 920. OPC-28326 does not affect on the mydriasis in rats[2]. |
| Animal Admin | Unilateral hindlimb ischemia is induced in 30- to 35-week-old male mice by resecting the right femoral and saphenous arteries. The mice are fed on regular chow (Ctrl), chow containing 0.02% (OPC(L)) or 0.05% (OPC(H)) OPC-28326, starting one week before the surgery (n = 10 for each group). Hindlimb blood perfusion is measured using a laser Doppler perfusion imager (LDPI) system. Excess hairs are removed from the limbs using depilatory cream before imaging, and mice are placed on a heating plate at 40°C. To avoid the influence of ambient light and temperature, the results are expressed as the ratio of perfusion in the right (ischemic) versus left (untreated) limb. The thigh muscles are harvested at 4 weeks and stained for CD31 (clone MEC13.1) to detect endothelial cells. Capillaries are identified by positive staining for CD31 and their morphology. Ten different fields from each tissue preparation are randomly selected and capillaries are counted. Capillary density is expressed as the number of capillaries per square millimeter. |
