Usage And Synthesis

Description

ONO-RS-082 (99754-06-0) is a reversible inhibitor of Ca2+-independent phospholipase A2(PLA2), IC50=7 μM for guinea pig lung PLA2.1Inhibits epinephrine-induced thromboxane production in platelets.1Inhibition of PLA2by ONO-RS-032 disrupts endosome tubule formation and maintenance of the Golgi complex.2-4Prevents Xenopus oocyte maturation at stage V.5

Uses

ONO-RS-082 is a potent PLA2 and epinephrine inhibitor.ONO-RS-082 is a phospholipase inhibitor.

in vitro

previous study found that human platelets stimulated by epinephrine led to enhanced turnover of phosphatidylinositol 4,5-bisphosphate, accumulated inositol trisphosphate, diacylglycerol, and phosphatidic acid, indicating stimulation of phospholipase c. it was shown that these responses could be completely blocked by inhibitors of alpha 2-adrenergic receptors including ono-rs-082 or removal of fibrinogen. in addition, epinephrine could evoked an increased turnover of ester-linked arachidonic acid in aspirin treated platelets that was inhibited by ono-rs-082 or the absence of fibrinogen. moreover, it was found that ono-rs-082 at 3.5 μm was able to inhibit epinephrine-stimulated thromboxane production in human platelets. ono-rs-082 could also disrupt endosome tubule formation and maintenance of the golgi complex [1].

in vivo

In vivo long-term activation of KCNK3 by ONO-RS-082 (50 mg/kg/day; preventive treatment, day 0 to day 21) reduces the development of PH in the MCT-PH model^[4].
In contrast, in vivo short-term KCNK3 activation by ONO-RS-082 (curative treatment) fails to reduce PH symptoms, which is attributed to the complete loss of KCNK3 expression in MCT-PH rats at days 14 to 21^[4].

Animal Model:	MCT- pulmonary hypertension (PH) rat model^[4]
Dosage:	50 mg/kg/day
Administration:
Result:	Reduced the development of PH in the MCT-PH model for long-term.
