Based on 1 Customer Validation

Drpitor1a is an orally active DRP1 GTPase inhibitor. Drpitor1a blocks mitochondrial fission, inhibits DRP1 GTPase activity, and reduces ROS levels. Drpitor1a induces mitochondrial fusion and mitochondria-dependent apoptosis by elevating Bak and Smac/Diablo and inhibiting Bcl-2. Drpitor1a inhibits proliferation in pulmonary arterial hypertension hPASMC and induces necrosis and autophagy mediators. Drpitor1a causes regression of non-small cell lung cancer tumors in mouse xenograft models and exhibits higher accumulation and efficacy in females. Drpitor1a can be used in research related to non-small cell lung cancer, myocardial ischemia-reperfusion injury, and pulmonary arterial hypertension.

Anti-cancer

Regulation of Cardiac Pump Function

Drpitor1a is an inhibitor of DRP1 GTPase activity, exhibits cardioprotective properties in cardiac I/R injury, and has antiproliferative effects in lung cancer cells^[1].

Mitochondrial Function

Drpitor1a fused the mitochondrial network in A549 cells expressing wild-type Drp1; moreover, it had no effect on the already fused mitochondrial network in A549 cells expressing the loss-of-function Drp1 K38A mutant^[2].
Drpitor1a effectively inhibits mitochondrial fragmentation in A549 cancer cells, with an IC₅₀ of 0.057 μM^[2].
Drpitor1a directly inhibits the GTPase activity of recombinant and endogenous Drp1 from PAH hPASMCs^[4].
Drpitor1a (0.1 μM; 4-5 h) inhibits mitochondrial fission in PAH hPASMCs but does not alter mitochondrial morphology in normal hPASMCs; it reverses the fragmented mitochondrial network in PAH BOECs but does not change mitochondrial morphology in control human BOECs^[4].

Others

Drpitor1a (1 μM; 48 h) inhibits the proliferation of PAH hPASMCs, but has no significant effect on the proliferation of normal hPASMCs^[4].

Apoptosis

Drpitor1a (5 μM; 48 h) induces apoptosis in PAH hPASMCs through a mitochondria-dependent apoptotic pathway^[4].

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

Immunofluorescence^[4]

Cell Line:

PAH hPASMC, normal hPASMC
Concentration:

0.1 μM
Incubation Time:

5 hours
Result:

Increased the accumulation of endogenous Drp1 on mitochondria in PAH hPASMC.
Did not alter total Drp1 expression in PAH hPASMC.\nIncreased the accumulation of exogenous Drp1 on mitochondria in PAH hPASMC.

Cell Proliferation Assay^[4]

Cell Line:

PAH hPASMC, normal hPASMC
Concentration:

1 μM
Incubation Time:

48 hours
Result:

Reduced cell proliferation in PAH hPASMC without significantly reducing the much lower proliferation rate of control hPASMC.

Apoptosis Analysis^[4]

Cell Line:

PAH hPASMC
Concentration:

5 μM
Incubation Time:

48 hours
Result:

Increased unstimulated apoptosis in 2 of 3 PAH hPASMC cell lines, with an accompanying significant increase in the expression of the apoptosis mediators Bak, Smac/Diablo, and suppression of the anti-apoptosis mediator, Bcl-2.
Slightly increased the expression of receptor-interacting protein and the LC3B II/I ratio.

Oxidative Stress

Cardiovascular Regulation

Drpitor1a inhibits mitochondrial fission and reduces ROS levels in a rat myocardial ischemia-reperfusion injury model^[3].

Cardiovascular Regulation

Regulation of Cardiac Pump Function

Drpitor1a (1 mg/kg; intravenous injection; once every 48 hours; from day 17 to day 27) regressed Monocrotaline (HY-N0750)-induced PAH in female rats by reversing adverse pulmonary vascular remodeling and RV hypertrophy, improved right heart function, and had no systemic vascular effects or toxicity^[4].

Others

Drpitor1a (0.1-1.0 mg/kg; i.v.; every 48 hours) showed a trend toward efficacy in female but not male MCT-PAH rats^[4].

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.
