Phenyracillin is the 2,5-diphenylpiperazine salt of benzylpenicillin. It is antibiotic from Pencillium spp. and also other fungal spp. Shows activity against gram-positive bacteria. Phenyracillin was well tolerated.

Enviradene (LY 127123) is a benzimidazole antiviral compound. It inhibited picornavirus replication and infection in vitro.

Ditercalinium is the antineoplastic agent. Ditercalinium itself is not a natural product, however, it is derived from the natural product 5,11-dimethyl-6H-pyrido-[4,3- b]carbazole (ellipticine) that was isolated in 1959. It is a rare example of a noncovalent DNA-binding ligand that forms bisintercalation complexes via the major groove of the double helix. Ditercalinium selectively recognizes certain GC-rich sequences in DNA. It preferentialy binds with antiparallel quadruplex sequence d(AG(3)[T(2)AG(3)](3)). Ditercalinium chloride can deplete mitochondrial DNA in both mouse and human cells. Ditercalinium chloride inhibits human DNA polymerase gamma activity as efficiently as does ethidium bromide. Ethidium bromide distributes diffusely in the mitochondria of HeLa cells, while ditercalinium chloride distributes granularly and hence may be strongly associated with mitochondrial DNA.

Pretamazium is thiazolium derivative patented by UK pharmaceutical company Wellcome Foundation Ltd. as antiphrastic compound, that active against parasitic nematodes.

Butoxylate is organic compound with significant analgesic or mydriatic activity after s.c. injection in mice and rats

Butopiprine is alkoxyethyl α-phenyl-α-piperidinoacetate possessing spasmolytic, local anesthetic, and antitussive activity.

Butocrolol amino alcohol derivative with β-adrenolytic, antiarrhythmic, and local anesthetic properties having sympatholytic and antiarrhythmic effects comparable to those of propranolol, but with lower local anesthetic effects.

Doreptide is the most active analog of PLG (Pro-Leu-Gly-NH2). It was evaluated as L-dopa potentiating agent for the treatment of Parkinson's disease.

Doxaminol is a recently developed beta-sympathomimetic agent, which has shown promising positive inotropic activity in experimental animal models. It is a dibenzoxepine derivative. In normal volunteers, doxaminol exhibits effects on noninvasive cardiological indices similar to those observed after cardiac glycosides. After single-dose application of doxaminol in cases of congestive heart failure, cardiac output and stroke volume increased, heart rate increased slightly, pulmonary and systemic arterial pressure remained constant, and peripheral vascular resistance decreased. No arrhythmias appeared, but one patient suffered an attack of angina.
