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.

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.

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.

CHEMICAL (ACHIRAL)


Stilonium Iodide (also known as MG 624) is a trimethylethanaminium derivative with ganglionic-blocking action. Stilonium Iodide acts as α7-nicotinic receptor antagonist and Stilonium Iodide inhibits transmission between preganglionic and postganglionic neurons in the Autonomic Nervous System. Stilonium Iodide inhibits nicotine-induced proliferation and angiogenesis in human microvascular endothelial cells of the lung. Stilonium Iodide displayed anti-angiogenic activity in Matrigel, rat aortic ring and rat retinal explant assays. Furthermore, MG624 suppressed angiogenesis of NCI-H69 human SCLC tumors in vivo in both the chicken chorioallantoic membrane (CAM) and nude mice model.

Quadazocine is a substituted hexahydro-2,6-methano-3-benzazocine patented by Sterling Drug Inc. as analgesics and narcotic antagonist. Quadazocine is a potent antagonist of μ opioid receptor, less potent antagonist of κ and δ opioid receptors. In monkeys for whom responding was reinforced by food delivery, quadazocine blocks the rate-decreasing effects of the µ-agonists alfentanil and fentanyl with greater potency than it blocked the rate-decreasing effects of the κ-agonists U69,593

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.

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.
