Piperlongumine (PL) is a pyridine alkaloid from Piper longum L
For GLP-1, the review confirmed insulinotropic effects on -cells during hyperglycaemia, glucagonostatic effects on -cells during hyperglycaemia (indirect, via somatostatin and insulin), gastric emptying delay, CNS appetite suppression, and indirect promotion of lipolysis via increased sympathetic activity
Riboflavin is also a co-factor for pyridoxine phosphate oxidase, the enzyme required for vitamin B6 production (as pyridoxal 5-phosphate) which is, in turn, an essential cofactor for the enzymes cystathionine-b-synthase (required for the conversion of homocysteine to cysteine) and cystathionine g-lyase (required for the conversion of cysteine to glutathione)
