What is the mode of action of streptomycin?

What is the mode of action of streptomycin?

What is the mode of action of streptomycin?

Streptomycin irreversibly binds to the 16S rRNA and S12 protein within the bacterial 30S ribosomal subunit. As a result, this agent interferes with the assembly of initiation complex between mRNA and the bacterial ribosome, thereby inhibiting the initiation of protein synthesis.

What is the mechanism of action of vancomycin?

Mechanism of Action: Inhibits cell wall synthesis by binding to the D-Ala-D-Ala terminal of the growing peptide chain during cell wall synthesis, resulting in inhibition of the transpeptidase, which prevents further elongation and cross-linking of the peptidoglycan matrix (see glycopeptide pharm).

What are Sulpha drugs give the mechanism of their action?

Sulfa drugs work by binding and inhibiting a specific enzyme called dihydropteroate synthase (DHPS). This enzyme is critical for the synthesis of folate, an essential nutrient. Mammals get folate from their diet, but bacteria must synthesize this vitamin.

This review summarizes some of the biological activities and discusses these in context o …

What kind of antibiotic is sulphafurazole used for?

Sulphafurazole Pharmacology. Sulfisoxazole is a sulfonamide antibiotic. The sulfonamides are synthetic bacteriostatic antibiotics with a wide spectrum against most gram-positive and many gram-negative organisms. However, many strains of an individual species may be resistant.

How does sulfafurazole enhance the anesthetic effect of warfarin?

Sulfafurazole enhances the anesthetic effect of short-acting intravenous barbiturates, by competitive displacement from binding sites on plasma albumin [222 ]. In an elderly woman taking warfarin, anticoagulation was potentiated when sulfisoxazole was given concurrently [ 223 ]. A similar case was reported in a 74-year-old man [ 224].

Are there any side effects to taking sulfisoxazole?

While sulfisoxazole is generally well-tolerated, its use can be accompanied by a variety of undesirable side effects. Hypersensitivity reactions and effects on the hematopoietic system are especially important.
