azauridin

A triazine nucleoside used as an antineoplastic antimetabolite. It interferes with pyrimidine biosynthesis thereby preventing formation of cellular nucleic acids. As the triacetate, it is also effective as an antipsoriatic.
MSH

A synthetic triazine analogue of uridine with antimetabolite activity. 6-azauridine inhibits de novo pyrimidine synthesis and DNA synthesis and is converted intracellularly into mono, di, and triphosphate derivatives, which incorporate into RNA and inhibit protein synthesis.

azlocilin

A semisynthetic ampicillin-derived acylureido penicillin.
MSH

A semisynthetic, extended spectrum acylampicillin with antibacterial activity. Azlocillin binds to penicillin-binding proteins (PBPs) located inside the bacterial cell wall, thereby inhibiting the cross-linking of peptidoglycans, which are critical components of the bacterial cell wall. This prevents proper bacterial cell wall synthesis, thereby results in the weakening of the bacterial cell wall and eventually leading to cell lysis.

aztreonam

A monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum. It is resistant to beta-lactamases and is used in gram-negative infections, especially of the meninges, bladder, and kidneys. It may cause a superinfection with gram-positive organisms.
MSH

A monocyclic beta-lactam antibiotic originally isolated from Chromobacterium violaceum with bactericidal activity. Aztreonam preferentially binds to and inactivates penicillin-binding protein-3 (PBP-3), which is involved in bacterial cell wall synthesis, thereby inhibiting bacterial cell wall integrity and leading to cell lysis and death. This agent differs from other beta-lactam antibiotics because it is resistant to beta-lactamase hydrolysis, and it is usually used to treat infections caused by gram-negative aerobic microorganisms.
