BACKGROUND Based on the efficacy of paromomycin ointment and recent ongoing clinical trials of combination of paromomycin and gentamicin, a new physical form of films of the paromomycin and gentamicin was prepared and anti-Leishmania activities of the prepared films were assessed in vitro and in vivo. METHODS Paromomycin 15% and gentamicin 0.5% was incorporated in a film using ethyl cellulose...

Leishmania donovani is a protozoan parasite that causes visceral leishmaniasis (VL) and is responsible for significant mortality and morbidity. Increasing resistance towards antimonial drugs poses a great challenge in chemotherapy of VL. Paromomycin is an aminoglycosidic antibiotic and is one of the drugs currently being used in the chemotherapy of cutaneous and visceral leishmaniasis. To under...

We determined the efficacy of the combination of the topical formulation 15% paromomycin sulfate/12% methylbenzethonium chloride (MBCL) and a short course (7 days) of parenteral meglumine antimonate (pentavalent antimony [Sb]) as treatment of American cutaneous leishmaniasis in Colombian patients. Patients were randomly assigned in unequal allocation (2:1:1:1) to group 1 (topical paromomycin/MB...

The codon-anticodon interaction on the ribosome occurs in the A site of the 30 S subunit. Aminoglycoside antibiotics, which bind to ribosomal RNA in the A site, cause misreading of the genetic code and inhibit translocation. Biochemical studies and nuclear magnetic resonance spectroscopy were used to characterize the interaction between the aminoglycoside antibiotic paromomycin and a small mode...

Vaginal trichomoniasis poses a difficult therapeutic challenge when metronidazole is ineffective or contraindicated. We conducted a retrospective study of 6.25% paromomycin cream in the treatment of nine women referred with cases of vaginal trichomoniasis where metronidazole resistance or allergy was present. Results obtained immediately and 1 month after treatment were reviewed. The median age...

Aminoglycoside antibiotics that bind to 16S ribosomal RNA in the aminoacyl-tRNA site (A site) cause misreading of the genetic code and inhibit translocation. Structures of an A site RNA oligonucleotide free in solution and bound to the aminoglycosides paromomycin or gentamicin C1a have been determined by NMR. Recently, the X-ray crystal structure of the entire 30S subunit has been determined, f...

The bacterial ribosome comprises 30 S and 50 S ribonucleoprotein subunits, contains a number of binding sites for known antibiotics and is an attractive target for selection of novel antibacterial agents. On the 30 S subunit, for example, the A site (aminoacyl site) close to the 3'-end of 16 S rRNA is highly important in the decoding process. Binding by some aminoglycoside antibiotics to the A ...
