Customer Review

Based on 1 Customer Validation

trans-2-Nonenal (trans-2-Nonen-1-al) is an endogenous peroxidation product of polyunsaturated fatty acids, acting as an inhibitor of COX and 12-LOX, as well as an inducer of apoptosis. trans-2-Nonenal is also a malodorous compound secreted by the human body, and its content gradually increases with aging. trans-2-Nonenal inhibits the activities of multiple enzymes such as platelet membrane-bound PTPase, preferentially covalently modifies proteins at lysine residues to form immunogenic adducts, and regulates platelet Arachidonic acid (HY-109590) metabolism. trans-2-Nonenal also exhibits significant cytotoxicity, reduces the viability of keratinocytes, promotes their apoptosis, and effectively decreases the thickness of epidermal models and the number of proliferating cells. trans-2-Nonenal is commonly used in studies of thrombotic, atherosclerotic diseases, renal adenocarcinoma, etc..

Biological Activity

Description

IC₅₀ & Target

12-LOX

All COX Isoforms :

All Lipoxygenase Isoforms :

In Vitro

trans-2-Nonenal (0.25-2 μM; 5 min) potently inhibits COX and 12-LOX activities in washed rabbit platelets, with an IC₅₀ of approximately 0.25 μM for suppressing the production of TXB₂, HHT and 12-HETE from exogenous arachidonic acid^[1].
trans-2-Nonenal (200 mM; 72 h) reacts with Nα-acetyl-L-lysine in vitro, producing two novel pyridinium-containing adducts, cis- and trans-Nα-acetyl-HHP-lysine, at a ratio of 1:1.4^[2].
trans-2-Nonenal (5-50 μM; 24 h) reduces the viability of normal human epidermal keratinocytes (NHEKs) derived from neonatal foreskins in a dose-dependent manner^[3].
trans-2-Nonenal (5-50 μM; 6 h) promotes apoptosis in normal human epidermal keratinocytes (NHEKs) derived from neonatal foreskin. Specifically, concentrations of 5 μM and 25 μM induce apoptosis, while 50 μM induces late apoptosis or necrosis^[3].

Apoptosis Analysis^[3]

Cell Line:

normal human epidermal keratinocytes (NHEKs) from neonatal foreskin
Concentration:

5 μM, 25 μM, 50 μM
Incubation Time:

6 h
Result:

Increased the rate of apoptosis relative to control at 5 μM and 25 μM.
Did not increase necrosis rate relative to control at 5 μM and 25 μM.
Increased the rate of late apoptosis or necrosis relative to control at 50 μM.

In Vivo

trans-2-Nonenal covalently binds to renal proximal tubular cell proteins to form detectable HHP-lysine adducts in Fe³⁺-NTA-induced oxidative renal injury in male Wistar rats, with immunoreactivity persisting up to 48 h post-injection^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

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.
