Effect of methoxyflavones contained in Kaempferia parviflora on CRE-mediated transcription in PC12D cells

Bioorg Med Chem Lett. 2020 Dec 1;30(23):127606. doi: 10.1016/j.bmcl.2020.127606. Epub 2020 Oct 7.

Abstract

The cAMP-response element (CRE) is critical in the formation of long-term memory. To prove the pharmacological effects of the methoxyflavones-rich residue (MRR) and its constituent methoxyflavones (1-9) extracted from the rhizomes of Kaempferia parviflora on the nervous system, we examined the effects of the MRR and methoxyflavones (1-9) on CRE-mediated transcription in PC12D cells. The MRR increased CRE-mediated transcription in PC12D cells. In addition, among methoxyflavones (1-9) isolated from MRR, compounds 1-4 increased CRE-mediated transcription. These results suggest that K. parviflora and methoxyflavone might be very useful materials for preventing and recovering from cognitive decline.
