Ayapin

2H,6H-[1,3]dioxolo[4,5-g]chromen-6-one

C10H6O4 (190.0266076)

Ayapin belongs to coumarins and derivatives class of compounds. Those are polycyclic aromatic compounds containing a 1-benzopyran moiety with a ketone group at the C2 carbon atom (1-benzopyran-2-one). Ayapin is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Ayapin can be found in sunflower, which makes ayapin a potential biomarker for the consumption of this food product.

Nitroxoline

Nitroxoline, potassium salt

C9H6N2O3 (190.0378406)

Nitroxoline is only found in individuals that have used or taken this drug. It is a urinary antibacterial agent active against susceptible gram-positive and gram-negative organisms commonly found in urinary tract infections. It is a fluorquinolone that is active against bacterial gyrases.This drug may also have antitumor activity by inhibition of ype 2 methionine aminopeptidase (MetAP2) protein which is involved in angiogenesis. Its antibacterial activity may stem from the metal ion complexation vital for bacterial growth.
