Retinal, All-trans is one of the forms of vitamin A. It is an isomer of 11-cis-retinal, transductor of light into the neural signals. Retinal, All-trans is converted to retinoic acid in vivo by the action of retinal dehydrogenase. Retinal, All-trans is associated with one of the two isoforms of cellular retinol-binding proteins (CRBP-I and CRBP-II). These proteins play important roles in retinoid biology and regulation of the metabolism of retinol and retinal.

Glyoxal refers to the reactive electrophilic species (RES) and is formed during different processes, e.g., lipid peroxidation, DNA oxidation. RES cause the damage of proteins and nucleotides and thus can cause different diseases in human, e.g., diabetes. Glyoxal reacting with free guanines in RNAs can be is used for chemical probing of RNA structure.

Pradofloxacin (trade name Veraflox) is a 3rd generation enhanced spectrum veterinary antibiotic of the fluoroquinolone class. It was developed by Bayer HealthCare AG, Animal Health GmbH, and received approval from the European Commission in April 2011 for prescription-only use in veterinary medicine for the treatment of bacterial infections in dogs and cats. The primary mode of action of fluoroquinolones involves interaction with enzymes essential for major DNA functions such as replication, transcription, and recombination. The primary targets for Pradofloxacin are the bacterial DNA gyrase and topoisomerase IV enzymes. Reversible association between Pradofloxacin and DNA gyrase or DNA topoisomerase IV in the target bacteria results in inhibition of these enzymes and rapid death of the bacterial cell. The rapidity and extent of bacterial killing are directly proportional to the drug concentration.

AMMONIUM O-PHENYLPHENOLATE (also known as Ortho-phenylphenol, ammonium salt) is a toxic agent, which is used as a pesticide.
