INN:lemildipine

Class (Stereo):
CHEMICAL (RACEMIC)



Lemildipine is a 1,4-dihydropyridine calcium channel blocker which is under phase III development by Banyu (Merck and Co), in Japan, for its potential to treat hypertension and cerebrovascular ischemia. In one study, involving five patients with essential hypertension accompanied by cerebrovascular disorder, lemildipine, administered orally at doses of 5 to 20 mg/day, significantly lowered blood pressure and increased cerebral blood flow. Another study in 31 patients with essential hypertension demonstrated that lemildipine has significant pressure lowering effects without affecting serum lipids. Worldwide rights to market the drug have been assigned to Kowa in Japan.

INN:famprofazone
Source URL:

Class (Stereo):
CHEMICAL (RACEMIC)

Conditions:

Famprofazone, a nonsteroidal anti-inflammatory agent, is found in a multi-ingredient medication (Gewodin) used for pain relief. It is available over-the-counter in Taiwan. Famprofazone transforms to methamphetamine (MA) and amphetamine (AM) following administration, which is responsible for the side effects of the drug. For example, famprofazone user might be interpreted as an illicit MA abuser in Taiwan because the user's urine tested positive for MA.

INN:namirotene [INN]

Class (Stereo):
CHEMICAL (ACHIRAL)

Namirotene [CBS-211A] is a retinoic acid analogue which was undergoing phase II trials with Chauvin in France as 0.02% eye drops for corneal ulcer. It was discontinued later. Namirotene is a synthetic analogue of retinoic acid with differentiation inducing and potential antineoplastic activities. Like other retinoic acid agents, namirotene binds to and activates retinoic acid receptors (RARs), thereby altering the expression of certain genes leading to cell differentiation and decreased cell proliferation in susceptible cells. When it was associated with 1 alpha,25(OH)2D3, CBS-211A strongly potentiated the 1 alpha,25(OH)2D3-induced inhibition of U937 cell proliferation and caused a dramatic increase in their differentiation toward monocytes/macrophages. The co-inducing effect of CBS-211A was restricted to U937 cells. Our data suggest that CBS-211A may have therapeutic implications in the treatment of certain kinds of myelomonocytic leukemia. CBS-211A also provides an interesting tool to understand the mechanisms involved in the differentiation of myelomonocytic cells.

Class (Stereo):
CHEMICAL (ABSOLUTE)

Mipragoside (also known as AGF 44), an isopropyl ester of monosialoganglioside GM1 that was developed as an anti-inflammatory agent. The topical treatment by this drug improved symptoms of patients with vernal keratoconjunctivitis. Mipragoside was in phase I in Italy for the treatment of inflammation; however, this study was discontinued.

INN:nifenalol
Source URL:

Class (Stereo):
CHEMICAL (RACEMIC)



Nifenalol is the beta-receptor antagonist. It has optical isomers. The racemic mixture and the levo-isomer are active in antagonizing beta-receptors, but the dextro-isomer is inactive. The levo-isomer seems to be about twice as active in blocking beta-receptors as the racemate. Nifenalol is virtually devoid of local anesthetic properties in contrast to procaine, propranolol, and butidrine. Nifenalol exacerbated the fighting behavior in male mice by foot-shock. Nifenalol has been studied in patients with coronary artery disease. It afforded the coronary patient good protection against angina and ischemic changes in the EKG. It was further noted that nifenalol had no antiarrhythmic action and that it was devoid of evident side effects. Nifenalol possessed weak action against tremorine and oxotremorine induced tremor.

Class (Stereo):
CHEMICAL (EPIMERIC)

Ciclotropium is quaternary ammonium compound with anticholinergic and parasympatholytic activity. Oral Cyclotropium bromide inhibited fasting and meal-stimulated colonic motility significantly without causing adverse side effects. After cyclotropium bromide, there was a significant correlation between antral contraction amplitude and gastric emptying.

INN:ebalzotan

Class (Stereo):
CHEMICAL (ABSOLUTE)

Ebalzotan is a selective serotonin (5-HT1A) receptor agonist, was chosen by Astra in the early 1990s as a candidate drug for the treatment of depression and anxiety. It has a modest affinity for the 5-HT(7). In vivo, ebalzotan induced all the typical effects of a 5-HT(1A) receptor agonist in rats: it decreased 5-HT synthesis (5-HTP accumulation) and 5-HT turnover (measured as the ratio of 5-hydroxyindoleacetic acid/5-HT), increased corticosterone secretion, induced the 5-HT(1A) syndrome (flat body posture and forepaw treading), inhibited the cage-leaving response, and caused hypothermia. Ebalzotan had been in phase I clinical trial for the treatment of major depressive disorder. However, this study was discontinued.
