Class (Stereo):
CHEMICAL (ABSOLUTE)

Cefoxazole is a semi-synthetic, first-generation cephalosporin with bactericidal activity against penicillin-resistant strains of S. aureus and used in the treatment of bovine mastitis.

INN:tameticillin
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)

Tamethicillin is a basic ester pro-drug of methicillin (MET) which is converted in the body by non-specific esterases to MET. Tamethicillin was used as an antibacterial agent in the veterinary as a useful alternative for the treatment of mastitis in livestock, especially in mastitis due to beta-lactamase-producing Staphylococcus.

INN:fenbenicillin
Source URL:

Class (Stereo):
CHEMICAL (EPIMERIC)

Fenbenicillin (phenoxybenzylpenicillin) is an acid-stable, orally active penicillin. Fenbenicillin demonstrated antibacterial activity in patients suffering from streptococcal, pneumococcal, and penicillin-sensitive staphylococcal infections.

INN:pirbenicillin
Source URL:

Class (Stereo):
CHEMICAL (ABSOLUTE)

Pirbenicillin is a broad-spectrum semisynthetic penicillin with activity against both gram-positive cocci and gram-negative bacilli. Pirbenicillin is less active than either carbenicillin or ticarcillin against Proteus spp. It is as active as carbenicillin against Serratia spp. and Enterobacter spp. Pirbenicillin demonstrated eight- and fourfold better minimal bactericidal concentration values towards Pseudomonas isolates than those of carbenicillin and ticarcillin, respectively. Pirbenicillin binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. The drug is somewhat more stable in serum than carbenicillin. Pirbenicillin does not appear to inactivate gentamicin as rapidly as carbenicillin.

INN:mecloqualone [INN]
Source URL:

Class (Stereo):
CHEMICAL (ACHIRAL)


Conditions:

Mecloqualone is a quinazoline-class GABAergic and an analog of methaqualone. It acts as an agonist of the beta subtype of GABAa receptor and induces sedative, hypnotic and anxiolytic effects. Mecloqualone was marketed (mostly in france) under the names Nubrene and Casfen for the treatment of insomnia. Mecloqualone is no longer prescribed because of concerns about its potential for abuse and overdose. In the United States, it is registered as a Schedule-I non-narcotic controlled substance.

INN:proligestone
Source URL:

Class (Stereo):
CHEMICAL (EPIMERIC)

Proligestone is a pregnane derivative patented by Koninklijke Nederlandsche Gist-en Spiritusfabriek N. V. As a progestin medication for veterinary medicine. Proligestone is used to control estrus in dogs and cats and has also been used to treat hypersexuality in dogs and cats. Administration of progestins in the dog may result in overproduction of growth hormone, suppression of the hypothalamic-pituitary-adrenocortical axis, and insulin resistance.

INN:levomequitazine [INN]

Class (Stereo):
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.
