Heptadecanoic acid is a fatty acid of exogenous (primarily ruminant) origin. Many "odd" length long chain amino acids are derived from the consumption of dairy fats (milk and meat).

1,3-Diphenylisobenzofuran is a fluorescent probe. It possesses a highly specific reactivity towards singlet oxygen forming an endoperoxide which decomposes to give 1,2-dibenzoylbenzene. 1,3-Diphenylisobenzofuran can detect the generation of reactive oxygen species (ROS).

2-Amino-6-(methylsulfonyl)benzothiazole is identified as a new development of improved pteridine reductase-1 (PTR1) inhibitors and anti-trypanosomatidic agents.
