Fencamfamin is a camphane derivative, although lacking typical sympathomimetic properties. It is structurally related to the phenylethylamines. It is a central nervous stimulant with pharmacological properties similar to amphetamine. Fencamfamin developed primarily as appetite suppressant or pscyhostimulant, not to increase awareness. Fencamfamin reduces REM sleep and prevents fatigue in subjects deprived of sleep. Fencamfamin raises a mood.

Sulfomyxin is an antibacterial sulfonamide. It is intended for use in chickens and turkeys as an aid in the treatment of disease caused or complicated by E. coli, such as colibacillosis and complicated chronic respiratory disease.

Spiramycin, a macrolide antibiotic, has been studied in the United States for the treatment of cryptosporidial diarrhea. Some reports suggest that spiramycin is useful in improving the symptoms of cryptosporidial diarrhea in some patients. It has been used in Europe and Canada for over 20 years to treat bacterial infections. Serious adverse effects from spiramycin are apparently rare, and no drug-associated deaths have been reported. Spiramycin inhibits translocation by binding to bacterial 50S ribosomal subunits with an apparent 1:1 stoichiometry. This antibiotic is a potent inhibitor of the binding to the ribosome of both donor and acceptor substrates. Spiramycin induces rapid breakdown of polyribosomes, an effect which has formerly been interpreted as occurring by normal ribosomal run-off followed by an antibiotic-induced block at or shortly after initiation of a new peptide. However, there is now convincing evidence that spiramycin, and probably all macrolides, act primarily by stimulating the dissociation of peptidyl-tRNA from ribosomes during translocation
