OPC-28326 is a selective peripheral vasodilator and an angatonist of α2-adrenergic receptor, with Ki of 2040, 285, and 55 nM for α2A-, α2B- and α2C-adrenoceptors, respectively.
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].
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 experiment: | 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. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
