The NF-E2-related factor 2 (Nrf2) is a key transcriptional regulator of antioxidant defense and detoxification. To directly monitor stabilization of Nrf2 we fused its Neh2 domain, responsible for the interaction with its nucleocytoplasmic regulator, Keap1, to firefly luciferase (Neh2-luciferase). It is shown herein that Neh2 domain is sufficient for recognition, ubiquitination and proteasomal degradation of Neh2-luciferase fusion protein. The novel Neh2-luc reporter system allows direct monitoring of the adaptive response to redox stress and classification of drugs based on the time-course of reporter activation. The novel reporter was used to screen a library of compounds to identify activators of Nrf2. The most robust and yet non toxic Nrf2 activators found—nordihydroguaiaretic acid, fisetin, and gedunin-induced astrocyte-dependent neuroprotection from oxidative stress via an Nrf2-dependent mechanism.

The present invention is directed to a method for differentiating between ASD phenotype 1, phenotype 2 and other ASD patients, wherein the method comprises,: administering an Nrf2-activator to a subject, and identifying the subject as an ASD phenotype 1 patient if the subject shows a negative response, as a phenotype 2 patient if he shows a positive response and as another ASD patient if he does not show a positive nor a negative response, wherein the subject is a patient previously diagnosed with idiopathic ASD or a subject displaying clinical signs of ASD. Likewise, the present invention is directed to an Nrf2-activator for use in differentiating between autism spectrum disorder (ASD) phenotype 1 patients, phenotype 2 patients and other ASD patients, wherein the Nrf2-activator is administered to a subject, wherein a phenotype 1 patient is identified by a negative response, a phenotype 2 patient is identified by a positive response and other ASD patients are identified by the absence of a positive and a negative wherein the subject is a patient previously diagnosed with idiopathic ASD or a subject displaying clinical signs of ASD.

The present invention relates to a compound which is (R)-3-(1,4-dimethyl-1H-benzo[d][1,2,3]triazol-5-yl)-3-(3-(((R)-2-ethyl-2,3-dihydropyrido[2,3-f][1,4]oxazepin-4(5H)-yl)methyl)-4-methylphenyl)propanoic acid (I), or a pharmaceutically acceptable salt thereof, in particular, the meglumine salt thereof, a pharmaceutical composition containing the compound and its use as an NRF2 activator.

The invention belongs to the technical field of preparation of medicines and health foods, and relates to an Nrf2 activator and application thereof in preparation of medicines/health food/dietary supplements. The Nrf2 activator comprises a compound I and a traditional Chinese medicine extract; the mass ratio of the compound I to the traditional Chinese medicine extract is (1-10): (0.5-5); the traditional Chinese medicine extract is one or more of an astragalus extract, a codonopsis pilosula extract, a salvia miltiorrhiza extract and a Chinese yam extract. The Nrf2 activator and a pharmaceutically acceptable carrier or excipient are used for preparing medicines/health food/dietary supplements for preventing or treating diabetic nephropathy. The Nrf2 activator can activate an Nrf2 signal channel in a targeted mode, remarkably inhibit the accumulation and oxidative stress of collagen and prevent and treat diabetic nephropathy.

The invention discloses an application of an Nrf2 activator to preparation of an anti-artificial joint wear particle induced osteolysis drug. Researches show that artificial joint wear particles can inhibit expression of a cell kernel factor E-2-related factor 2 (Nrf2), and reduce activity of an anti-oxidation reaction element (ARE) regulated and controlled by the downstream of the Nrf2, reduced capacity of controlling an oxidation-reduction reaction in a cell causes active oxygen (ROS) and a lipid peroxidation product malondialdehyde (MDA) in osteoblast to be increased, so that the ROS generation and degradation homeostasis is disordered, the activity of the osteoblast is inhibited, and the balance between osteoclast and the osteoblast is broken. After the Nrf2 activator Oltipraz is added, the content of the ROS in cells can be obviously reduced, and the generation of the lipid peroxidation product MDA is inhibited. In addition, a mouse skull dissolution model is established by implanting CoCrMo nano wear particles under the skin of a mouse skull, effective intervention is applied by intraperitoneal injection of Oltipraz, and in-vivo experiments further prove that the Oltipraz has a remarkable inhibition effect on osteolysis induced by the artificial joint wear particles.
