M&B 39279

M&B 39279 is an inhibitor of protoporphyrinogen oxidase (Protoporphyrinogen Oxidase). M&B 39279 induces protoporphyrin IX accumulation, light-dependent lipid peroxidation, degradation of membranes and organelles, and reduction of photosynthesis. M&B 39279 functions through the mechanism of action of diphenyl ether herbicides, and can be used for studies on PPO inhibition and herbicide mechanisms of action.

Biological Activity

Description

In Vitro

M&B 39279 inhibits protoporphyrinogen oxidase in membranes of potato tuber mitochondria, maize etioplasts, mouse liver mitochondria and yeast mitochondria, with IC₅₀ values of 15 nM, 80 nM, 0.5 μM and 3 μM, respectively^[1].
M&B 39279 (100 μM; 3-30 hr light, 30 hr darkness) induces light-dependent diphenyl ether-type phytotoxicity in detached Galium aparine leaves. After treatment with 100 μM under 50 μmol m^-2 sec^-1 light for 3 hours, chloroplast envelope damage appears first, followed by progressive degradation of membranes and organelles, rapid loss of photosynthetic capacity, delayed chlorophyll degradation, and membrane leakage associated with lipid peroxidation^[2].

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.
