The invention also relates to a novel intermediate compound produced in the production process.An excitatory amino acid such as glutamic acid modulates various physiological processes such as long term potentiation (learning and memory), synaptic plasticity development, motion control, respiration, cardiovascular modulation, and perception in the central nervous system (CNS) of a mammal.Presently, glutamate receptors are classified into two major groups, that is, “an ionotropic type in which the receptor has an ion channel structure”: ion channel type glutamate receptor (iGluR), and “a metabotropic type in which the receptor is coupled to a G protein”: metabotropic glutamate receptor (mGluR) (see, Non-Patent Document 1). It appears that receptors of either class mediate normal synaptic transmission in accordance with an excitatory pathway. It also appears that they are involved in modification of synaptic binding from the development stage throughout the lifetime (see, Non-Patent Document 2).Eight subtypes of the metabotropic glutamate receptor that have been identified so far are classified into three groups (group I, II, and III) depending on pharmacological characteristics and intracellular second messengers to which they are coupled. Among them, group II receptor (mGluR2/mGluR3) binds with adenylate cyclase, and inhibits the accumulation of cyclic adenosine-1-phosphate (cAMP) stimulated by forskolin (see, Non-Patent Document 3).

(canceled) This invention was made with government support under R15 CA139364 awarded by the National Institutes of Health. The government has certain rights in the invention.The human retinoid X receptors (hRXRs) consist of three identified isoforms (α, β, γ) that function as transcription promoters often in partnership with other members of a larger nuclear receptor (NR) family of transcription regulators including the thyroid receptor (TR), the vitamin D receptor (VDR), the liver X receptor (LXR), the peroxisome proliferator-activated receptor (PPAR), and the retinoic acid receptor (RAR). While 9-cis-retinoic acid (9-cis-RA) and docosahexaenoic acid (DHA) have been shown to bind to hRXRs and promote RXR element (RXRE) regulated transcription (i.e. function as RXR agonists), it is still unclear if RXR has a bona fide endogenous molecular ligand. RXR has been described as the central NR regulator, because it often plays a critical role, either as a permissive or non-permissive partner, in heterodimer complexes that must be formed with the other NRs to regulate their respective response elements.Recent studies have identified several RXR-selective-binding molecular ligands (rexinoids) that can modulate ...
