生物活性

CI-1020 (PD156707) is an orally active and selective antagonist targeting endothelin (ETA) with an IC50 value of 0.3 nM. CI-1020 blocks intimal hyperplasia in human saphenous veins completely in organ culture. CI 1020 inhibits hypoxic pulmonary hypertension and blocks ET-1-induced pressor responses following oral administration[1][2][3].

Animal Model: normal rats [2]
Dosage: 30 mg/kg
Administration: oral administration (p.o.)
Result: Inhibited the ET-A and has no significant effect on basal blood pressure in normotensive rats.
Animal Model: basal blood pressure in normotensive rats[4]
Dosage: 40 mg/kg/day
Administration: oral administration (p.o.)
Result: Reduced the increase in RV/LV+S and the percentage DEL induced by chronic hypoxia.
Lowered the increase in pulmonary resistance in isolated perfused lungs significantly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
