Edogesterone (PH-218) is steroid with progestational and antiandrogenic properties.

Fucoxanthin isis a marine carotenoid mainly found in brown algae, giving them a brown or olive-green color. Fucoxanthin is investigated for its anti-inflammatory, antinociceptive and anti-cancer effects. In vivo studies have demonstrated that oral administration of fucoxanthin inhibited carcinogenesis in an animal model of duodenal, skin, colon and liver cancer. Fucoxanthin causes antitumor and anticarcinogenic effects by inducing G1 cell-cycle arrest and apoptosis by modulating expression of various cellular molecules and cellular signal transduction pathways, but the exact mechanism of anti-cancer action of fucoxanthin is not fully elucidated. Fucoxanthin regulates lipids metabolism, the effect most likely mediated by AMK-activated protein kinase. A clinical trial of fucoxanthin against non-alcoholic fatty liver disease is ongoing.

Esoxybutynin is (S)-enantiomer of oxybutynin. Esoxybutynin exerts antimuscarinic properties. Racemic oxybutynin is used clinically to treat urinary incontinence. Sepracor was developing (S)-oxybutynin, a single-isomer version of Alza's Ditropan (racemic oxybutynin), a muscarinic acetylcholine receptor antagonist, as a potential treatment for urinary incontinence.

Osaterone acetate (previously known as TZP-4238), a synthetic steroidal anti-androgen agent. Osaterone acetate is used in veterinary in Europe in the treatment of benign prostatic hyperplasia (BPH) in male dogs. Osaterone acetate inhibits the effects of an excess of male hormone (testosterone) through various mechanisms. It competitively prevents the binding of androgens to their prostatic receptors and blocks the transport of testosterone into the prostate. Osaterone acetate was also investigated in Japan in the treatment of prostate cancer and BPH and, in addition, was studied in postmenopausal osteoporosis in humans. However, these studies were discontinued.

Nexeridine, a pethidine derivative, is an opioid analgesic.

Spiroxasone is a synthetic, steroidal antimineralocorticoid of the spirolactone group patented by Merck & Co., Inc. as a diuretic and antihypertensive agent. Spiroxasone acts as potent aldosterone antagonists in animals and humans.

Josamycin propionate, a tasteless josamycin derivative suitable for the preparation of pediatric oral suspension. After oral administration Josamycin propionate underwent metabolic transformation to Josamycin, semi-synthetic 16-membered ring macrolide, that acts via protein synthesis inhibition.
