CDIBA

CDIBA is a cytosolic phospholipase A2 (cPLA2) inhibitor. CDIBA inhibits the activation of cPLA2 in rat diaphragm tissue. CDIBA reduces the level of mitochondrial reactive oxygen species in rat diaphragm tissue after prolonged mechanical ventilation. CDIBA attenuates protein degradation, muscle atrophy and decreased muscle strength in the diaphragm of rats after prolonged mechanical ventilation. CDIBA can be used in studies related to ventilator-induced diaphragmatic dysfunction.

In Vivo

CDIBA (30 mg/kg; i.p.; single injection at ventilation onset; 5 mg/kg/h; i.v.; continuous infusion; 12 hours) attenuates ventilator-induced diaphragm dysfunction in rats by reducing cPLA2 activation, mitochondrial ROS production, calpain activity, muscle atrophy, and improving diaphragm contractile force^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Wistar rats (adult male, SPF level, 450-550 g, ventilator-induced diaphragm dysfunction model)^[1]
Dosage:

30 mg/kg (i.p. injection); 5 mg/kg/h (continuous i.v. infusion)
Administration:

i.p. (single injection at ventilation onset); i.v. (continuous infusion; 12 hours)
Result:

Significantly reduced cPLA2 activation in the diaphragm.
Decreased mitochondrial H₂O₂ production in the diaphragm.
Downregulated diaphragm calpain activity.
Reduced the expression of atrophy-related genes Atrogin-1 and MuRF-1 in the diaphragm.
Increased the cross-sectional area of slow-twitch and fast-twitch diaphragm muscle fibers.
Improved diaphragm contractile function, including increased maximal tetanic forces, elevated force-frequency curve responses, and enhanced fatigue tolerance, compared to untreated ventilated rats.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
