Clocinizine is an antihistamine derivative of diphenylmethylpiperazine. Clocinizine is a competitive and reversible H1 receptor antagonist. The drug is marketed in Spain under tradename Senioral in combination with phenylpropanolamine for temporary relief of nasal congestion in colds, rhinitis, and sinusitis.

Lexofenac is an ibufenac derivative. It was developed as anti-inflammatory and analgesic agent.

Afeletecan (Bay 38-3441) is a camptothecin glycoconjugate which stabilizes the active lactone form of camptothecin and allows selective uptake into tumor cells. Afeletecan is a topoisomerase inhibitor. Afeletecan was in phase I clinical trials with Bayer for the treatment of cancer; however, development appears to have been discontinued.

FIGOPITANT is a tachykinin NK1 receptor antagonist. It can inhibit scratching behavior in an atopic dermatitis model. It is under investigation in clinical trials to obtain preliminary pharmacokinetics data and information about FIGOPITANT safety and tolerability in healthy volunteers.

Cinanserin is a 5-hydroxytryptamine receptor antagonist; it shows a low affinity to 5-HT2b binding sites and a 4-to 10-fold lower affinity to 5-HT2c receptor binding sites than for 5-HT2a sites. Nevertheless, at concentrations normally used 5-HT2c receptor blocking effects are still likely. Experiments on animal have shown that intravenous administration of cinanserin significantly reduces systemic burn edema and leukocyte-endothelial interactions.

Pyrroliphene is a dialkylaminodiphenylbutanol ester with antitussive and analgesic activities. In clinical trials the major side effect of Pyrroliphene was sedation, and the other side effect liabilities were similar to those of morphine.

Cinaciguat acts specifically on oxidized/haem-free soluble guanylyl cyclase by binding to the enzyme's haem pocket and mimicking the nitric-oxide-bound haem group. It is in clinical development for the treatment of acute decompensated heart failure. Cinaciguat had been in phase II clinical trials. However, trials were terminated early because of an excess of hypotension in the cinaciguat arms and subsequent slow enrolment.

Rivoglitazone hydrochloride (CS-011) is a thiazolidinedione-derivative peroxisome proliferator–activated receptor (PPAR)-γ agonist. It has been developed as potential treatment in type 2 diabetes mellitus and was shown to decrease plasma glucose and triglyceride levels in a dose-dependent manner in animals. Phase II and III clinical studies have assessed the efficacy and safety of rivoglitazone hydrochloride in patients with type 2 diabetes mellitus.

Etoloxamine is an antihistamine.

Lobeglitazone (trade name Duvie; Chong Kun Dang Pharmaceutical Corporation) was developed as effective and safe antidiabetic TZD drug. Lobeglitazone is a peroxisome proliferator-activated receptor-γ agonist. Lobeglitazone was conceptually designed by modification of the rosiglitazone structure with a substituted pyrimidine. Lobeglitazone has a p-methoxyphenoxy group at the 4-position of the pyrimidine moiety. Lobeglitazone showed more potent activity than the reference compounds (pioglitazone and rosiglitazone) with an EC50 value of 0.018 uM in a type 2 diabetes animal model, which is 16 times lower than pioglitazone (EC50 0.30 uM). Lobeglitazone exhibited similar efficacy profiles in glycemic control and lipid modulation to pioglitazone, but with a 30 times smaller dose in clinical studies. Lobeglitazone displays 12 times higher affinity to PPARγ than rosiglitazone and pioglitazone. Lobeglitazone acts as an insulin sensitizer by binding and activating Peroxisome Proliferator-Activated Receptors (PPAR) gamma within fat cells. By promoting the binding of insulin at fat cells, lobeglitazone has been shown to reduce blood sugar levels, lower hemoglobain A1C (HbA1C) levels, and improve lipid and liver profiles. Lobeglitazone was approved by the Ministry of Food and Drug Safety (Korea) in 2013. Lobeglitazone is not approved for use by either the Food and Drug Administration (USA), Health Canada, or by the European Medicines Agency for use in the management of diabetes.
