6'-hydroxydihydrocinchonidine is a metabolite of quinine, with antimicrobial and antitumor activity, and inhibitory effect on Trypanosoma brucei and Streptococcus pneumoniae.

4,5-Dichlorocatechol is a substrate of the broad-spectrum chlorocatechol 1,2-dioxygenase of pseudomonas chlororaphis RW71.

Peptide fragment corresponding to residues 1 - 40 of Nogo-66, the domain of the myelin protein Nogo that inhibits axonal outgrowth. Acts as a competitive antagonist at the Nogo-66 receptor (NgR); blocks Nogo-66- and CNS myelin-induced inhibition of axonal growth, but does not reduce myelin-associated glycoprotein (MAG) inhibition of neurite outgrowth in vitro. Promotes regeneration of hemisected spinal axons and locomotor recovery following spinal injury in vivo.
