1-Palmitoyl-2-oleoyl-sn-glycero-3-phospho-rac-(1-glycerol) ammonium salt (POPG-NH4) ia a phospholipid. Can be used as an emulsifier in pharmaceutical compositions. Used for lipid modification of superhydrophobic surfaces. POPG-NH4 transforms the surface into a highly hydrophilic surface only at the positions where the solution is applied.

Stepronin is clinically used as an expectorant. It inhibits airway secretion in vitro by both decreasing Cl- secretion from epithelial cells and mucus glycoprotein secretion from submucosal glands. The mucolytic activity of stepronine does not involve the gastric mucous coating and that the drug does not exert adverse effects on the gastric mucosa. It is a new chemical immunosuppressant drug, which has the effect of preventing graft-versus-host-disease (GVHD) in a mouse model. The mechanism by which this compound acts as an immunosuppressant appears to be similar to cyclosporine A (CyA), although, in contrast to CyA, it is not toxic for animals and humans. Stepronin has an antiviral effect as well and is able to block, indirectly, the human immunodeficiency virus–1 (HIV-1) replication in mononuclear cells in vitro.

Rabacfosadine was approved in 2017 under the brand name Tanovea-CA1 for the treatment of canine lymphoma. In addition, this drug has demonstrated effectiveness against non-Hodgkin's lymphoma in dogs, as well as canine cutaneous T-cell lymphoma, and relapsed canine B-cell lymphoma. Rabacfosadine a prodrug, which is hydrolyzed intracellularly to the metabolites, 9-(2-phosphonylmethoxyethyl)-N6-cyclopropyl-2,6-diaminopurine (cPrPMEDAP) and 9-(2-phosphonylmethoxyethyl) guanine (PMEG). PMEG is then converted to its active phosphorylated form, which is a chain-terminating inhibitor of the replicative deoxyribonucleic acid (DNA) polymerases.

QS-21 is a purified soapbark tree (Quillaja saponaria) extract that enhances the ability of the immune system to respond to vaccine antigens. QS-21 is a promising adjuvant candidate for use in humans due to the ease of purification, its improved safety profile, and its ability to enhance cellular and humoral immunogenicity. The mechanism of action of QS-21 was speculated to be similar to QA, forming complexes with cholesterol that intercalate into the cell membrane lipids. This intercalation creates pores in the membrane to accelerate the uptake of a co-delivered antigen by the antigen presenting cells. Multiple clinical trials using QS-21 as an adjuvant, demonstrated satisfactory safety profiles and enhanced immunogenicity in immunocompromised volunteers

Capromorelin is a potent ghrelin receptor agonist. Capromorelin is indicated for appetite stimulation in dogs. Plasma insulin-like growth factor-I (IGF-I) was elevated progressively over a 5-d course of daily oral dosing in dogs. In healthy older adults at risk for functional decline, administration of the capromorelin may improve body composition and physical function. Adverse events included fatigue, insomnia, and small increases in fasting glucose, glycosylated hemoglobin, and indices of insulin resistance.
