Xenin-8, a C-terminal octapeptide, is a biologically active fragment of Xenin. Xenin is a 25-amino acid peptide of the neurotensin/xenopsin family. Xenin-8 stimulates basal insulin secretion and potentiates the insulin response to glucose in a dose-dependent manner (EC50=0.16 nM).

InsB (9-23) is an insulin B-chain peptide that binds to a class II histocompatibility complex (MHC) allele called I-Ag7.

Bismaleimide has heat resistance, oxidation resistance and radiation resistance, and can be used to prepare electrical insulation materials, wear-resistant materials, reinforced plastic additives, grinding wheel adhesives, etc.
