Mirincamycin, a protein biosynthesis inhibitor was studied as an antibacterial agent. It was shown that mirincamycin could be promising candidate in the therapy and prophylaxis of multidrug-resistant falciparum malaria. Moreover, in combination with 4 or 8-aminoquinolines it could be used for the treatment and relapse prevention of vivax malaria. In addition, was studied the anti-relapse activity of mirincamycin in the Plasmodium cynomolgi sporozoite-infected Rhesus monkey model. However, the negative P. cynomolgi hypnozoite data indicates that mirincamycin is unlikely to have potential as a clinical anti-relapse agent.

Enisoprost is a prostaglandin E1 analog. Enisoprost exerts immunosuppressive activity and gastric antisecretory effect. Enisoprost was being studied for the treatment of peptic ulcer and transplant rejection. Enisoprost development has been discontinued.

Johnson and Johnson was developing usistapide, a microsomal triglyceride transfer protein (MTTP) inhibitor, for the treatment of obesity and type 2 diabetes. Usistapide, also known as JNJ-16269110 and R256918, has been used in trials studying the treatment of obesity, overweight, metabolic diseases, nutrition disorders, and nutritional and metabolic diseases. Usistapide was removed from the company pipeline and appears to have been discontinued.

Combretastatin is a phenol derivative isolated from the bark of Combretum caffrum, commonly known as South African Bush Willow. Combretastatin is an effective antimitotic agent, and like colchicine, inhibited tubulin polymerization and stimulated tubulin-dependent GTP hydrolysis.

FENPYROXIMATE is a pyrazole acaricide widely used in the prevention of acarids (mites) in fruit plant gardens. It is a potent inhibitor of the mitochondrial proton-translocating NADH-quinone oxidoreductase (complex I).

Penoxsulam, a fluorinated benzenesulfonamid rice herbicide is sold under the brand name Granite. Penoxsulam is an acetolactate synthase inhibitor that kills plants through a mechanism not present in animals and has few to no adverse effects on most species. Besides, was found that Chlorella Vulgaris dietary supplementation could protect the commercially valuable freshwater fish Oreochromis niloticus against penoxsulam toxicity and may be a potential feed supplement for Nile tilapia in aquaculture.

Maridomycin is a macrolide antibiotic. Sreptomyces sp. No. B-5050 was found to produce maridomycin. Maridomycin was found to be composed of six components, maridomycins I, II, III, IV, V and VI. Their structures are different from each other in acyl moieties at C3 and C4" positions. Maridomycins I, II, III, IV, V and VI showed similar antibacterial spectra against Gram-positive bacteria including acid-fast bacteria. Maridomycin has bacteriostatic activity rather than bactericidal activity. Prominent therapeutic effect was observed against certain Gram-positive bacterial infection in mice.

Sulfinalol is a hydroxyphenylalkanolamine derivative patented by Sterling Drug Inc. as the antiarrhythmic, antihypertensive, vasodilating, and adrenergic agent. Oral administration of sulfinalol reduces the pressure of conscious spontaneously hypertensive rats. Antihypertensive action of sulfinalol was inhibited by propranolol pretreatment. Sulfinalol demonstrates effective beta-adrenergic blockade at the antihypertensive dose tested as judged by inhibition of the chronotropic responses to sympathetic stimulation and isoproterenol in pithed rats. In the renal hypertensive dog. sulfinalol lowered both systolic and diastolic blood pressure to normal values with an only slight change in heart rate.

Eucatropine is known as an anticholinergic agent, which acts as antagonist of muscarinic cholinergic receptors.
