Antimicrobianos

b-Apo-oxytetracycline is a tetracycline antibiotic and is used for the treatment of bacterial infections. It binds to the 30S ribosomal subunit, inhibiting protein synthesis.

Pirazinecarboxamide (Pyrazinamide) is an antitubercular agent with action on Mycobacterium tuberculosis by disrupting membrane energetics and is used for treating tuberculosis in combination with other drugs.

Lamivudine (commonly called 3TC) is a potent nucleoside analogue reverse transcriptase inhibitor. It is one of the front line treatments for HIV.  It is an analogue of cytidine, and can inhibit both types (1 and 2) of HIV reverse transcriptase as well as the reverse transcriptase of hepatitis B. It needs to be phosphorylated to its triphosphate form before it is active.

Ceftriaxone is a broad-spectrum cephalosporin antibiotic that is used for the treatment of bacterial infections in different locations such as the skin, soft tissue and respiratory tract. This drug works by inhibiting mucopeptide synthesis in the bacterial cell wall. As a result, bacteria will produce defective cell walls leading to cell death.

Anti-viral; inhibitor of NS5A protein

Streptomycin sulfate is an antibiotic that inhibits the growth of bacteria by binding to the ribosomal subunit and interfering with protein synthesis. It is used in culture media for the production of human antibodies as well as in drug therapy for methicillin-resistant staphylococcus. Streptomycin sulfate has a high specific activity and low sensitivity, but it also has a low solubility in water. The active form of streptomycin sulfate is streptomycin A, which is produced by the addition of a phenyl ring to neomycin sulfate. In plant roots, streptomycin sulfate inhibits cyanogenic glycosides from being hydrolyzed into hydrogen cyanide (HCN) and benzaldehyde.

Sitafloxacin sesquihydrate is a fourth-generation fluoroquinolone antibiotic with action on bacterial DNA gyrase and topoisomerase IV and is used for treating respiratory, urinary, and gastrointestinal infections.

Tenofovir diphosphate triethylamine (mixture of diastereomers) is an antiviral compound, which is a synthetic chemical product derived from the parent compound, tenofovir. This formulation includes a mixture of diastereomers to enhance its solubility and bioavailability. The compound primarily functions as a nucleotide reverse transcriptase inhibitor (NRTI). It targets viral reverse transcriptase enzymes, inhibiting DNA synthesis and subsequent viral replication by causing premature chain termination.

Anti-viral; non-nucleoside reverse transcriptase inhibitor

Antibiotic of anthracycline class; DNA synthesis inhibitor

Enrofloxacin is a rapidly bactericidal antibiotic, that inhibits bacterial growth by binding to the 50S ribosomal subunit and blocking protein synthesis, thereby preventing the bacteria from making new proteins. Enrofloxacin also has strong activity against gram-positive bacteria, including Clostridium perfringens which is an anaerobic bacterium that causes food-borne illness. This antibiotic is used for the treatment of acute bacterial infections in humans, such as, skin or soft tissue infections, urinary tract infections (UTIs) and septicemia (bloodstream infection). Enrofloxacin has shown excellent bioavailability with high serum protein binding capacity. Additionally, it has good efficacy against clinical isolates of Escherichia coli and Klebsiella pneumoniae. Enrofloxacin can be used effective in treatments for Pseudomonas aeruginosa and Enterobacter species.

Cefuroxime is a second-generation cephalosporin antibiotic with action on bacterial cell wall synthesis and is used for treating respiratory tract infections, urinary tract infections, and Lyme disease.

Antibiotic of fluoroquinolone class; DNA replication inhibitor

Cefuroxime axetil is a prodrug of cefuroxime with action on bacterial cell wall synthesis and is used for treating bacterial infections like sinusitis, bronchitis, and gonorrhea.

Clofazimine is a phenazine dye antibiotic with action on bacterial DNA interference and is used for treating leprosy and erythema nodosum leprosum.

25-Desacetylrifampin is the main metabolite of rifampicin, used in the treatment of tuberculosis. 25-Desacetylrifampin has partial actvity.
