Monomethyl glutaric acid is a metabolite of dibasic esters(DBEs) by nasal respiratory and olfactory mucosae in vitro demonstrated that hydrolysis of DBEs yields mainly the monomethyl esters (monomethyl adipate monomethyl. glutarate and monomethyl succinate).

Neurotensin (1-8) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

N-Acetyldopamine dimer-2 (compound 2) is a N-acetyldopamine dimer that can be isolated from the yellow powder form Periostracum Cicadae with antioxidant and anti-inflammatory activities. N-Acetyldopamine dimer-2 inhibits oxidized low-density lipoprotein (LDL) oxidation, ROS generation, NO production, and NF-κB activity.
