Butaprost, a structural analog of PGE2, is a selective agonist for the EP2 receptor subtype. EP2 receptors are expressed on human neutrophils and on respiratory, vascular, and uterine smooth muscle. Butaprost binds with about 1/10 the affinity of PGE2 to the recombinant murine EP2 receptor and does not bind appreciably to the other murine EP receptors or the DP, TP, FP, and IP receptors. Butaprost has frequently been used to pharmacologically define the EP receptor expression profile of various human and animal tissues and cells. Butaprost effectively reduces the subconjunctival scarring response. Given the significance of wound healing modulation in blebs, butaprost's inhibitory effect on subconjunctival Tenon's fibroblasts may be beneficial in managing postoperative scarring in glaucoma surgery.

Doxybetasol is the corticosteroid. It is an impurity of Betamethasone, which is a glucocorticoid used as an anti-inflammatory agent. Doxybetasol also has anti-inflammatory and anti-allergic properties.

Etiocholanone is an androstane neurosteroid. Etiocholanone potentiates GABA-A receptor currents and exerts anticolvunsant properties in rodents. Etiocholanolone demostrates pyrogenic properties.

Aliconazole is an antifungal imidazole derivative, developed by Knoll Pharmaceuticals. Aliconazole was previously in phase III clinical trials for the determination of efficacy in the topical treatment of cutaneous fungal infections. The proposed use includes superficial fungal infections, including dermatomycoses, tinea versicolor, and cutaneous and vaginal candidiasis

Demecycline is a tetracycline antibiotic drug. Tetracyclines have a broad spectrum of anti-microbial activity and act by interfering with bacterial protein synthesis. Demecycline is used to treat a wide range of infections caused by bacteria. Some of these infections are: Severe acne; Infections of the brain and liver caused by the bacteria Leptospira; Infection caused by Brucella bacteria (brucellosis); Infections caused by Rickettsiae micro-organisms transmitted by lice, fleas, ticks and mites; Infections of the sex organs and organs associated with urination (genito-urinary infections) such as an infection called chancroid, non-gonococcal urethritis; Rare infections such as Tularaemia and bubonic plague. The following undesirable effects have been reported for demecycline: loss of appetite, nausea, vomiting, diarrhea, inflammation of the tongue, difficulty in swallowing, intestinal inflammation, and inflammatory lesions, rashes, redness of the skin, pigmentation, sensitivity to light, acute kidney failure and others.

Cyclopregnol (neurosterone) is a synthetic pregnane steroid, developed in the 1950s by the British Drug Houses, Ltd, for the treatment of psychiatric disorders, such as anxiety, depression and obsessive behavior. In a clinical study, cyclopregnol was not superior to placebo and was inferior to chlorpromazine.

Pregnanediol is a chief steroid metabolite of progesterone that is biologically inactive and occurs as pregnanediol glucuronate in the urine. Pregnanediol has two hydroxyl groups, at 3-alpha and 20-alpha. A test can be done to measure the amount of pregnanediol in urine. The urine test offers an indirect way to measure progesterone levels in the body. It is a standard in the colorimetric determination of urinary pregnanediol in clinical laboratories.

Aglepristone (RU 46534) is a competitive progesterone antagonist; it binds to progesterone receptors (PRs) without inducing the molecular cascade associated with progesterone. Its affinity to PRs is higher than progesterone (3.12, 3.8, and 9.26 times greater in the bitch, doe rabbit,and queen, respectively). Aglepristone can therefore beused in various progesterone-dependent physiological orpathologic conditions, with the aim of blocking the action of progesterone. Aglepristone has proven to be an effective and safe means of inducing pregnancy termination or parturition in a large number of domestic species. In domestic species, aglepristone is routinely used for the treatment of pyometra and feline mammary fibroadenomatous hyperplasia, both of which are progesterone dependent. Aglepristone is marketed under the brand name Alizin used as the treatment option for unwanted mating and pregnancy in dogs

Menarini was developing oral nepadutant (MEN 11420), a potent and selective tachykinin neurokinin-2 receptor antagonist, for the treatment of infant colic. Nepadutant has been used in trials studying the treatment of colic, infantile colic, and infantile functional gastrointestinal disorders. MEN 11420 is a glycosylated derivative of the potent, selective, conformationally-constrained tachykinin NK2 receptor antagonist MEN 10627. MEN 11420 competitively bound with high affinity to the human NK2 receptor stably transfected in CHO cells, displacing radiolabelled [125I]-neurokinin A and [3H]-SR 48968 with Ki values of 2.5+/-0.7 nM (n = 6) and 2.6+/-0.4 nM (n = 3), respectively.
