Anecortave is a novel angiogenesis inhibitor used in the treatment of the exudative (wet) form of age-related macular degeneration. It will be marketed by Alcon as anecortave acetate (AA) for depot suspension under the trade name Retaane. In 2007 they received their letter of approval for Retaane’s indication to treat wet age-related macular degeneration (AMD), but final approval would require the completion of an additional clinical study. As a result, the Anecortave Acetate Risk-Reduction Trial (AART) was continued to be supported by Alcon. This study looked at the efficacy of Retaane to reduce the progression of the dry from of AMD to the wet-form. In 2008, Alcon Inc. announced they were terminating the development of anecortave acetate for the prevention of developing sight-threatening choroidal neovascularization secondary to age-related macular degeneration. In 2009, Alcon Inc. announced they would terminate the development of the drug for the reducing intraocular pressure associated with glaucoma. Currently, anecortave acetate is not on the market or being made for therapeutic use by Alcon Inc.[7] This could be due to the lack of efficacy of clinical trials with anecortave acetate or because of newer more efficacious products that are currently on the market. Anecortave acetate functions as an antiangiogenic agent, inhibiting blood vessel growth by decreasing extracellular protease expression and inhibiting endothelial cell migration. Its angiostatic activity does not seem to be mediated through any of the commonly known pharmacological receptors. RETAANE blocks signals from multiple growth factors because it acts downstream and independent of the initiating angiogenic stimuli and inhibits angiogenesis subsequent to the angiogenic stimulation. Recently was discovered, that phosphodiesterase 6-delta (PDE6D) was a molecular binding partner of AA and this provided insight into the role of this drug candidate in treating glaucoma.

Alniditan is a non-indole migraine-abortive agent. It is a benzopyran derivative The action of sumatriptan is thought to be mediated by 5-hydroxytryptamine (5-HT)1D-type receptors. Alniditan did not attenuate substance P-induced inflammation, suggesting that the mediating receptors are located prejunctionally. In vitro alniditan exhibited less vasoconstrictive effects on the rat basilar artery than did sumatriptan, although at a very high concentration, alniditan caused intensive constriction, most likely through a mechanism independent from 5-HT receptor activation. Alniditan dose dependently attenuated the neurogenic inflammation and was more potent than sumatriptan. Adverse effects are: head pressure, paraesthesia, and hot flushes.

Raclopride is a salicylamide neuroleptic, that acts as a selective antagonist of D2 dopamine receptors both in vitro and in vivo. Tritium-labelled raclopride has properties that demonstrate its usefulness as a radioligand for the labelling of dopamine-D2 receptors : 3H-Raclopride has a high affinity for the rat and human dopamine-D2 receptors, the non-specific binding of 3H-raclopride is very low, not exceeding 5% of the total binding and the distribution of the 3H-raclopride binding sites in the brain closely correlates with the dopaminergic innervation. The binding of 3H-raclopride is blocked by dopamine-D2 agonists and antagonists, while the D1 agonist SKF 38393 and the Dl antagonist SCH 23390 have much less potency. The interaction of dopamine with 3H-raclopride binding results in a shallow competition curve, which suggests that 3H-raclopride, similar to other dopamine-D2 radioligands, labels both high and low agonist affinity states of the dopamine-D2 receptor. The in vivo receptor binding studies performed with 3H-raclopride also demonstrate its favorable properties as a dopamine-D2 receptor marker in vivo In contrast to some other compounds used as radioligands, raclopride enters the brain readily and binds with a low component of non-specific binding in all dopamine-rich brain areas. A saturation curve may be achieved in vivo binding studies since injections of increasing concentrations of 3H-raclopride appears to be saturated at concentrations above 25 mkCi (corresponding to approximately 5 nmol/kg). Raclopride antagonizes apomorphine-induced hyperactivity in the rat at low doses (ED50 = 130 nM/kg i.p.) but induces catalepsy only at much higher doses (ED50 = 27 mkM/kg i.p.). Radiolabelled raclopride has been used as a ligand for in vitro and in vivo autoradiography in rat and primate brains. Raclopride C 11 is used with positron emission tomography (PET) as a clinical research tool to determine dopamine type 2 (D 2) receptor density in the human brain under normal and pathological conditions. For example, raclopride C 11 used in PET studies has served to confirm the age-related decrease in striatal dopamine D2 receptor density, which may be associated with a decline in the motor as well as cognitive functions. In patients with Alzheimer's disease, raclopride C 11 may be used to examine neuroreceptor distribution and quantities, which may help in the analysis of degenerative alterations of neuron populations and neuroreceptor systems in patients with this disease. In Huntington's disease, in which degeneration of neostriatal interneurons occurs (postsynaptic to the dopaminergic input), specific binding of raclopride C 11 to D 2 receptors may serve as one of the parameters in predicting performance in cognitive tasks.

Colesevelam (trade name Welchol) a non-absorbed, polymeric, lipid-lowering agent intended for oral administration. Colesevelam is poly(allylamine hydrochloride) cross-linked with epichlorohydrin and alkylated with 1-bromodecane and (6-bromohexyl)-trimethylammonium bromide. Colesevelam hydrochloride is a hydrophilic, water-insoluble polymer that is not hydrolyzed by digestive enzymes and is not absorbed. Colesevelam is part of a class of drugs known as bile acid sequestrants. Colesevelam hydrochloride, the active pharmaceutical ingredient in Welchol, is a non-absorbed, lipid-lowering polymer that binds bile acids in the intestine, impeding their reabsorption. As the bile acid pool becomes depleted, the hepatic enzyme, cholesterol 7-α-hydroxylase, is upregulated, which increases the conversion of cholesterol to bile acids. This causes an increased demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme, HMG-CoA reductase, and increasing the number of hepatic LDL receptors. These compensatory effects result in increased clearance of LDL-C from the blood, resulting in decreased serum LDL-C levels. Colesevelam is indicated as an adjunct to diet and exercise to reduce elevated low-density lipoprotein cholesterol (LDL-C) in patients with primary hyperlipidemia as monotherapy and to improve glycemic control in adults with type 2 diabetes mellitus, including in combination with a statin. The expanded use of colesevelam in adults with type 2 diabetes mellitus is an example of drug repositioning.
