SKF-83822 is a D1/D5 receptor agonist, which activates D1-like receptors coupled to stimulation of adenyl cyclase (AC), but not phosphoinositide (PI) hydrolysis. SKF-83822 is used as a tool compound to study the role of AC-coupled D1 receptors.

Lobelanidine is one of lobelia alkaloids that are the constituents of Lobelia inflata. Lobelia Chinensis Lour. (L. chinensis) is a plant of the Campanulaceae family that is commonly known as "xi-mi-cao", and "she-she-cao". It has been widely used as an antidote, diuretic, and hemostat in traditional Chinese medicine for decades. Lobelanidine is known for its emetic and anticancer activity.

Padimate A (Pentyl dimethyl PABA; Amyl paradimethylaminobenzoate) is an ingredient in some sunscreens. This aromatic chemical absorbs ultraviolet rays thereby preventing sunburn. In Europe this chemical was withdrawn in 1989s. In the US it was never approved for use in sunscreens. Padimate A was capable of provoking phototoxic reactions. Explanation for the paradox of a sunscreen that promotes "sunburn" is that, as affected users have concluded, the product was ineffective. The similarity between sunburn and a phototoxic response has delayed recognition of this adverse effect until now.

4-Nitro-3-trifluoromethylaniline is one of the two main products of flutamide metabolism in human liver microsomes. Also, it is a major urinary metabolite of S-1 [3-(4-fluorophenoxy)-2-hydroxy-2-methyl-N-[4-nitro-3-(trifluoromethyl)phenyl]-propanamide] - a member of a series of potent selective androgen receptor modulators.

(1,2,6,7-3H)-Testosterone is a radiolabeled form of the corresponding steroid hormone. It can be used to study testosterone metabolism and androgen receptor binding in tissues.

Protopine is the isoquinoline alkaloid found primarily in the plant families Berberidaceae, Ranunculaceae, Rutaceae, Fumariaceae. It has diverse biological activities, such as anti-thrombotic, anti-inflammatory, anti-parasitic activity, antimicrobial activity, as well as hepatoprotective effects in animal models. The biological activities of protopine are associated with its ability selectively inhibits K(ATP) channels by targeting on SUR1 subunit. In addition, was discovered that β2 -adrenoceptor (β2 -AR) is a target for antiasthma activities of protopine. On this target, binding of the drug occurs on the amino acid residual of Ser 169 through the formation of hydrogen bonds and receptor‐drug bumps.

Lespedin (Kaempferitrin) is extracted in significantly high quantities from the leaves of Cinnamomum osmophloeum (C.O) and Bauhinia forficata, and are used as an antidiabetic herbal remedy in China and Brazil. Commercial product using dry Cinnamomum osmophloeum leaves has been sold locally in Taiwan. Oral administration of kaempferitrin reduced blood sugar in diabetic rats. Lespedin possessed significant antiosteoporotic activity. Combined with its limited estrogen-like side effect, Lespedin can be regarded as an idealistic antiosteoporotic candidate for human osteoporosis diseases. Kaempferitrin was found to have an acute lowering effect on blood glucose in diabetic rats and to stimulate the glucose uptake percentile, as efficiently as insulin in muscle from normal rats.
