Diprogulic acid (Dikegulac) is used as a precursor in vitamin C synthesis. It is plant growth regulator for hedges. Dikegulac is used to differentially kill terminal apices, and it analogously inhibits basic metabolic functions in dividing cells, but not stationary cells, in suspension culture. At the lowest concentrations, dikegulac partially suppresses division of the isolated tobacco protoplasts. Higher concentrations are required to produce visual cytoplasmic damage to the protoplasts, which probably first occurs at the level of the plasmalemma, as the vacuoles can be released intact. Later, tonoplast disruption occurs. It does not inhibit mature leaves.

Midaglizole (also known as DG 5128) is a α2 adrenoceptor antagonist. Daiichi Pharmaceutical developed this drug as an oral antidiabetic agent and to treat asthma. However, further study of this drug was discontinued.

Diphenan is p-benzyl-phenyl-carbamate. Various workers have reported that diphenan will rid children of oxyurids and it has been claimed to be nontoxic and tasteless and to have the advantage of being a vermicide as opposed to a vermifuge. An attempt has been made to assess the efficacy of diphenan as a vermicide. Diphenan was given far in excess of the normal dosage. Subsequent examnation showed few cures and these mostly in lightly infested children. The condition of many was unchanged and that of some worse after treatment. No toxic reactions were encountered. Moreover, diphenan was found to have no detectable anthelmintic effect when given in high dosage in the treatment of enterobiasis.

Disulergine is the synthetic 8 alpha-amino ergoline. Disulergine is the dopamine D2 receptor agonist and prolactin release inhibitor. Disulergine was as potent as dopamine in inhibiting growth hormone release but, in contrast to dopamine, was nearly ineffective in stimulating the secretion of the hormone.

Nisbuterol, a nicotinic acid ester, is a bronchodilator.

Etisulergine (CQ 32-084) is an ergoline derivative. Etisulergine stimulates both dopamine D1- and D2-receptors, antagonizes alpha-adrenergic and serotonin 5-HT2 receptors. Etisulergine demonstrated antiparkinsonian activity in patients.

Etofenprox is a synthetic pyrethroid insecticide compound used in agricultural production. Etofenprox acts on the nervous system of insects by disrupting their neuron sodium channels. Etofenprox is a contact-kill adulticide used to control a wide variety of insects including weevils, beetles, aphids, moths, whiteflies, thrips, borers, fleas and mosquitoes. Etofenprox is well tolerated by mammals, including cats, and is environmentally friendly.

Proadifen is an inhibitor of drug metabolism and cytochrome P450 enzyme system activity. It stimulated the release of prostacyclin (PGI2) from the rabbit aorta, bovine aorta and human umbilical vein in vitro, but had no effect on cultured smooth muscle from the bovine aortic media. In human platelets, proadifen inhibited prostaglandin and thromboxane production induced by A23187, thrombin, and ADP. Proadifen might thus constitute the prototype of a new class of antiplatelet drugs.

Droclidinium is the muscarinic receptors antagonist. It is an anticholinergic, spasmolytic agent.
