Alitame [l-α-aspartyl-N-(2,2,4,4-tetramethyl-3-thioethanyl)-d-alaninamide] is an amino acid-based sweetener developed by Pfizer Central Research from l-aspartic acid, d-alanine, and 2,2,4,4-tetraethylthioethanyl amine. A terminal amide group instead of the methyl ester constituent of aspartame was used to improve the hydrolytic stability. The incorporation of d-alanine as a second amino acid in place of l-phenylalanine has resulted in optimum sweetness. The increased steric and lipophilic bulk on a small ring with a sulfur derivative has provided a very sweet product and good taste qualities. Alitame is noncariogenic. From an oral intake, 7–22% is unabsorbed and excreted in the feces. The remainder is hydrolyzed to aspartic acid and alanine amide. The aspartic acid is normally metabolized, and the alanine amide is excreted in the urine as a sulfoxide isomer, sulfone, or conjugated with glucuronic acid. U.S. Food and Drug Administration has approved alitame for use as per acceptable daily intake (ADI) value.

Class (Stereo):
CHEMICAL (ABSOLUTE)

Telinavir (previously known as SC-52151) was developed as an anti-HIV aspartyl protease inhibitor for the treatment of HIV Infections. Telinavir participated in Phase I/II clinical study. In spite of the drug was well tolerated no antiviral activity was produced and further development of the drug was discontinued.

Class (Stereo):
CHEMICAL (UNKNOWN)

Cypothrin is a synthetic pyrethroid insecticide, developed by American Cyanamide for the control of ticks and marketed under the tradename Panecto. The compound exhibited systemic insecticidal activity in the model of flies infestation in mice and ixodicidal activity in against larvae of Boophilus microplus.

INN:viprostol

Class (Stereo):
CHEMICAL (MIXED)

Viprostol (also known as CL115,347), a prostaglandin E2 congener that was studied as an antihypertensive agent. Viprostol has a potent and prolonged blood pressure lowering effect in many models of hypertension. In clinical studies, viprostol has been demonstrated to lower arterial blood pressure significantly in man following transdermal and/or intravenous administration. The antihypertensive action of viprostol has been suggested to be the result of peripheral vasodilatation. In addition, the drug participated in a clinical trial in normal subjects and in patients with Raynaud's phenomenon. It was found the optimal dosage was 1000 ug; the effect could last for 84 hours; higher dosage may be associated with a "steal" phenomenon.

NCT00813865: Phase 2 Interventional Completed Gaucher Disease
(2009)

Class (Stereo):
CHEMICAL (ABSOLUTE)

Amicus Therapeutics was investigating afegostat (isofagomine; Plicera; HGT-3410; AT-2101), an orally available pharmacological chaperone molecule, which binds to glucocerebrosidase (Gba) and stimulates proper folding and trafficking of the enzyme, for the potential treatment of Parkinsons disease(PD) and Gaucher disease. Afegostat specifically and reversibly binds GCase in the ER with highaffinity; this stabilizes the active form of the enzyme in the ER and increases trafficking of GCase to lysosomes. In 2006, Orphan Drug designations were granted in the U.S. and E.U. in 2006 and 2007, respectively. However, this research has been discontinued.

CHEMICAL (ABSOLUTE)

Levomequitazine is the L-enantiomer of mequitazine. The antihistaminergic activity mainly resides in the S-enantiomer, L-mequitazine, whereas the anticholinergic activity mainly resides in the D-enantiomer. It was shown, that L-enantiomer of mequitazine is less potent antagonist of human M3 muscarinic acetylcholine receptors than D-enantiomer. In vitro binding studies have shown that the affinity of L-mequitazine for H1 receptors is approximately ten times higher and to muscarinic receptors ten times lower, compared to d-mequitazine. Memory impairment was observed after administration of L-mequitazine 10 mg alone on delayed recall. This could be due to indirect effects of H1 receptor blockade. L-mequitazine 10 mg produced mild driving impairment, whereas L-mequitazine 2.5 and 5.0 mg show no effects on driving. Levomequitazine had been in phase III clinical trials by Pierre Fabre for the treatment of perennial allergic rhinitis and seasonal allergic rhinitis.

Class (Stereo):
CHEMICAL (ABSOLUTE)

Apadenoson (BMS-068645) is a selective adenosine 2A agonist that contains a methyl ester group which undergoes esterase hydrolysis to its acid metabolite. Apadenoson had been in phase III clinical trials by Forest (now a part of Allergan) for the treatment of coronary artery disease. However, this study has been terminated.
