Phenylbutazone is a member of the class of pyrazolidines that is 1,2-diphenylpyrazolidine-3,5-dione carrying a butyl group at the 4-position. It has a role as a non-narcotic analgesic, a non-steroidal anti-inflammatory drug, an antirheumatic drug, a peripheral nervous system drug, a metabolite and an EC 1.1.1.184 [carbonyl reductase (NADPH)] inhibitor.

1,2-phenylenediamine appears as colorless monoclinic crystals if pure; technical grade brownish-yellow crystals or a sandy brown solid. Used in manufacture of dyes, photography, organic synthesis.

Phthalic anhydride appears as a colorless to white lustrous solid in the form of needles with a mild distinctive odor. Moderately toxic by inhalation or ingestion and a skin irritant. Melting point 64°F Flash point 305°F. Forms a corrosive solution when mixed with water. Used in the manufacture of materials such as artificial resins.

Vitamin B12 is a member of the vitamin B complex. It contains cobalt, and so is also known as cobalamin. It is exclusively synthesised by bacteria and is found primarily in meat, eggs and dairy products. There has been considerable research into proposed plant sources of vitamin B12. Fermented soya products, seaweeds, and algae such […]

Bacampicillin is a prodrug of ampicillin, a broad-spectrum, semisynthetic, beta-lactam aminopenicillin antibiotic with bactericidal activity. Bacampicillin is hydrolyzed in vivo by esterases to its active metabolite ampicillin. Ampicillin binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains […]

Benzocaine is an ester of paraaminobenzoic acid, lacking the terminal diethylamino group of procaine, with anesthetic activity. Benzocaine binds to the sodium channel and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions. Depolarization of the neuronal membrane is inhibited, thereby blocking the initiation and conduction of nerve impulses.

Pipemidic Acid is a pyridopyrimidine antibiotic derivative of piromidic acid with activity against gram-negative bacteria, as well as some gram-positive bacteria. Pipemidic acid exhibits greater activity than piromidic acid or nalidixic acid and shows moderate activity against bacteria that are resistant to piromidic acid and nalidixic acid.

Piperacillin is a broad-spectrum semisynthetic, ampicillin-derived ureidopenicillin antibiotic. Piperacillin binds to penicillin binding proteins (PBP), the enzymes that catalyze the synthesis of peptidoglycan, a critical component of the bacterial cell wall. This blockade leads to the interruption of cell wall synthesis, consequently, leading to bacterial cell growth inhibition and cell lysis.

Piroxicam is a nonsteroidal anti-inflammatory drug of the oxicam class used to relieve the symptoms of painful inflammatory conditions like arthritis.

Benzoic acid is a compound comprising a benzene ring core carrying a carboxylic acid substituent. It has a role as an antimicrobial food preservative, an EC 3.1.1.3 (triacylglycerol lipase) inhibitor, an EC 1.13.11.33 (arachidonate 15-lipoxygenase) inhibitor, a plant metabolite, a human xenobiotic metabolite, an algal metabolite and a drug allergen. It is a conjugate acid […]
