INN:adicillin
Source URL:

Class (Stereo):
CHEMICAL (RACEMIC)

Adicillin (Penicillin N) is a penicillin derivative produced by Cephalosporium acremonium. Adicillin is dextrorotatory. Inactivated by penicillinase as is penicillin G, but differs from the common penicillin by its antibacterial activity and hydrophilic character. Active against Sarcina lutea, Proteus vulgaris, Salmonella typhimurium, Diplococcus pneumoniae. Shows practically no activity against B. subtilis and Staph. aureus. The toxicity is somewhat less than that of penicillin G, although penicillin N is excreted more slowly.

INN:trospectomycin

Class (Stereo):
CHEMICAL (ABSOLUTE)

Trospectomycin is an aminocyclitol antibiotic similar in structure to spectinomycin. The drug was originally developed by Pharmacia & Upjohn. It is a 6'-propyl analogue of spectinomycin, and lacks the aminosugars in glycosidic linkage which are thought to be responsible for the ototoxicity and nephrotoxicity associated with the aminoglycosides. The mechanism of action of trospectomycin is similar to that of its parent compound, spectinomycin: it binds to the bacterial 30S ribosome and inhibits protein synthesis. The transport mechanism for its delivery to its target site does not appear to be oxygen dependent, and this explains the in-vitro activity of trospectomycin against anaerobic organisms. Trospectomycin has activity against a broad spectrum of pathogenic organisms including Streptococcus, Haemophilus, Gardnerella, Neisseria, Peptococcus, Peptostreptococcus, Bacteroides, Mobiluncus, Chlamydia, Mycoplasma and Ureaplasma spp. Results of in-vivo testing suggest potential utility in a variety of clinical conditions including non-gonococcal urethritis, chlamydial cervicitis, gonorrhoea, pelvic inflammatory disease, pneumonia, anaerobic infections and meningitis. Trospectomycin progressed to late stage clinical trials for treatment of pelvic inflammatory disease (chlamydia) before being abandoned for commercial reasons as the third generation cephalosporins and second generation macrolides in development and use were judged superior at the time.

Class (Stereo):
CHEMICAL (ACHIRAL)

Idoxifene (also known as CB 7432), a novel selective estrogen receptor modulator, is originally discovered at the CRC Centre for Cancer Therapeutics, Institute. This drug participated in clinical trials phase II in patients with locally advanced/metastatic breast cancer resistant to tamoxifen. In addition, in phase III in postmenopausal women after one year of idoxifene treatment. However, both studies were discontinued because of insufficient effectiveness.

Class (Stereo):
CHEMICAL (RACEMIC)


Conditions:

Nicainoprol, also known as RU-42924, is calcium channel antagonist and a putative class I antiarrhythmic agent. Nicainoprol was shown to be useful in the prevention and treatment of arrhythmias associated with acute myocardial infarction. Nicainoprol had been in phase II clinical trials for the treatment of arrhythmia. However, this research has been discontinued.

INN:mibolerone
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)


Conditions:

Mibolerone is a synthetic anabolic steroid. It binds both androgen and progesterone receptors and exerts both androgenic and progestagenic actions. Mibolerone (CHEQUE® Drops) was used in veterinary for estrous (heat) prevention in adult female dogs not intended primarily for breeding purposes. No prescription preparation, human or veterinary, is currently known to contain mibolerone worldwide.

Class (Stereo):
CHEMICAL (ACHIRAL)



Mofegiline (MDL 72,974A or (E)-2-(4-fluorophenethyl)-3-fluoroallylamine, hydrochloride), is a selective and irreversible inhibitor of monoamine oxidase type B (MAO-B) both in vitro and in vivo. In addition, mofegiline inhibits semicarbazide-sensitive amine oxidase activity from human serum and saphenous vein. In phase II studies, MDL 72,974A is proving to be a useful adjunct to conventional therapy of Parkinson's disease. It seems mofegiline development was discontinued.
