Aztreonam is a synthetic monocyclic beta-lactam antibiotic, which has a very high affinity for penicillin-binding protein 3 (PBP-3).Target: Penicillin-binding proteins 3 (PBP-3)Aztreonam is a synthetic monocyclic beta-lactam antibiotic (a monobactam), with the nucleus based on a simpler monobactam isolated from Chromobacterium violaceum. It was approved by the U.S. Food and Drug Administration in 1986. It is resistant to some beta-lactamases, but is inactivated by extended-spectrum beta-lactamases. Aztreonam has no useful activity against gram-positive or anaerobic microorganisms Aztreonam is similar in action to penicillin. It inhibits mucopeptide synthesis in the bacterial cell wall, thereby blocking peptidoglycan crosslinking. It has a very high affinity for penicillin-binding protein 3 (PBP-3) and mild affinity for PBP-1a. Aztreonam binds the penicillin-binding proteins of gram-positive and anaerobic bacteria very poorly and is largely ineffective against them. Aztreonam is bactericidal but less so than some of the cephalosporins

Mtb-IN-2 significantly decreases colony-forming units (CFU) in spleen of murine tuberculosis models, and distinguishes both drug-sensitive and drug-resistant Mtb H37Rv strains. Mtb-IN-2 affects methionine metabolism but not folate pathway directly.
Sulfamethoxazole is a sulfonamide bacteriostatic antibiotic.Target: AntibacterialSulfonamides are structural analogs and competitive antagonists of para-aminobenzoic acid (PABA). They inhibit normal bacterial utilization of PABA for the synthesis of folic acid, an important metabolite in DNA synthesis. The effects seen are usually bacteriostatic in nature. Folic acid is not synthesized in humans, but is instead a dietary requirement. This allows for the selective toxicity to bacterial cells (or any cell dependent on synthesizing folic acid) over human cells. Bacterial resistance to sulfamethoxazole is caused by mutations in the enzymes involved in folic acid synthesis that prevent the drug from binding to it.
Sulfacetamide (Sulphacetamide), a bacteriostatic sulphonamide, is a popular antibiotic prescribed for treating ocular infections[1][2].

Ceftazidime(GR20263) is an antibiotic useful for the treatment of a number of bacterial infections.Target: AntibacterialCeftazidime is an antibiotic useful for the treatment of a number of bacterial infections. It is a third-generation cephalosporin. As with all antibiotics, ceftazidime is not used to treat viral infections. Cephalosporins have activity against Gram-positive and Gram-negative bacteria. The balance of activity tips toward Gram-positive organisms for earlier generations; later generations of cephalosporins have more Gram-negative coverage. Ceftazidime is one of the few in this class with activity against Pseudomonas. It is not active against Methicillin-resistant Staphylococcus aureus. From Wikipedia.
