S-nitrosoglutathione (GSNO) is an endogenous S-nitrosothiol that acts as a NO pool. The level of GSNO is tightly regulated by S-nitrosoglutathione reductase (GSNOR), an enzyme that degrades GSNO. GSNOR inhibitors offer a potentially promising option for the management of pre-eclampsia, a cause of maternal death and of perinatal morbidity. The GSNO treatment of traumatic brain injury improved neurobehavioral functions. GSNO can increase the expression of certain proteins at concentrations present in the normal human airway. GSNO has an important role in regulating respiratory function (breathing) and preventing inflammation in the respiratory tract, that is why this compound participated in phase I clinical trials for patients with asthma. In addition, GSNO was studied in the cystic fibrosis airway. The obtained results have shown that GSNO replacement therapy could be an effective treatment. In addition, GSNO was investigated for patients with chronic obstructive pulmonary disease.

Class (Stereo):
CHEMICAL (ABSOLUTE)

Seglitide (previously known as L363,586 or MK-678), a cyclic, hexapeptide analog of somatostatin-14, is a somatostatin receptor 2 (SSTR2) agonist. This compound was studied in Alzheimer's disease. Besides, it possessed inhibitory actions on rat growth hormone (GH) release and thus could have a role in the treatment of acromegaly. Intravenous and intranasal administration of seglitide to diabetic subjects was effective in reducing both fasting and postprandial hyperglycemia. Thus, this compound could be useful in the control of unstable diabetes. In addition, preclinical studies have shown that seglitide had potential as a treatment for diabetic retinopathy and macular degeneration. However, the further studied of this compound were discontinued.

Class (Stereo):
CHEMICAL (ABSOLUTE)

Diprogulic acid (Dikegulac) is used as a precursor in vitamin C synthesis. It is plant growth regulator for hedges. Dikegulac is used to differentially kill terminal apices, and it analogously inhibits basic metabolic functions in dividing cells, but not stationary cells, in suspension culture. At the lowest concentrations, dikegulac partially suppresses division of the isolated tobacco protoplasts. Higher concentrations are required to produce visual cytoplasmic damage to the protoplasts, which probably first occurs at the level of the plasmalemma, as the vacuoles can be released intact. Later, tonoplast disruption occurs. It does not inhibit mature leaves.

CHEMICAL (RACEMIC)



Racemetirosine is an orally active inhibitor of the enzyme tyrosine 3-monooxygenase, and consequently of the synthesis of catecholamine. At dosages of 600 to 3500mg daily, it is effective in controlling the hypertensive episodes and symptoms of catecholamine excess in phaeochromocytoma during preparation for surgery. Oral Racemetirosine is well absorbed and absorption appears constant in each individual over a wide dosage range. The drug is largely excreted via the kidneys, but extrarenal elimination has not been studied. Case reports on the clinical use of Racemetirosine in phaeochromocytoma indicate that the drug controls hypertension and symptoms of catecholamine excess in most patients during preparation for surgical removal of a tumor. In some cases, the addition of Racemetirosine to phenoxybenzamine plus propranolol has resulted in adequate control of symptoms previously unresponsive to the adrenergic blocking regimen. Drowsiness and sedation have been the most frequently reported side effects of Racemetirosine treatment.

CHEMICAL (ABSOLUTE)


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.

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.
