Dose-dependent adverse effects on the skin and mucous membranes are observed most commonly, including cheilitis, mucous membrane dryness, epistaxis, dry eyes, blepharoconjunctivitis, erythematous eruptions, and xerosis. Alteration of epidermal surfaces may facilitate Staphylococcus aureus colonization and, rarely, subsequent infection. Hair loss, exuberant granulation tissue formation, photosensitivity, and dark adaptation dysfunction are rarer occurrences.

Colonization with resistant gram-positive organisms (e.g., methicillin-resistant Staphylococcus aureus)... 

BS, Bacillus subtilis CA, Candida albicans SA, Staphylococcus aureus SC, Saccharomyces cerevisiae TM, Trichophyton mentagrophytes PN, Penicillium nonatum KB, LOVO (colon cancer), P388 are cell lines in cytotoxic activity testings. 

In contrast to Gram-negatives, many Gram-positive bacteria employ post-translationally modified peptides processed from larger precursors as QS signal molecules. In Staphylococcus aureus, for example, a family of peptide (7-9 amino acid residues) thiolactones which vary in the primary amino acid sequence but contain a conserved cysteine at position 5 control the expression of cell wall colonization factors and exotoxins [24-26]. 

Recently, the piperazine intermediate 15 for the total synthesis of (—)-lemon-omycin (9) was reported by Fukuyama et al. [14], (—)-Lemonomycin possesses interesting antibiotic activity against methiciUin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium, as well as cytotoxicity against the human colon tumor cell line HCT-116 [15]. The reaction of 2-isocyanoethyl phenyl carbonate 11 gave Ugi product 14, which was further transformed to a piperazine intermediate 15 (Scheme 2). 

Bacterial colonization of lower respiratory tract.

Nasal colonization of resistant Staphylococcus aureus Intranasal Apply 2 times/day for 5 days. 

Mupirocin (Bactroban) inhibits a specific enzyme responsible for tRNA synthesis in susceptible bacteria. This drug is used topically to treat skin infections caused by Staphylococcus aureus or Streptococcus pyogenes. Likewise, mupirocin can be administered by nasal spray to treat local colonization of S. aureus in the nasal mucosa. This idea may be especially helpful in preventing systemic infection in individuals such as health care workers who are exposed to an outbreak of resistant strains of S. aureus. Local/topical administration of this drug is well tolerated, although some irritation of the skin may occur during topical use, and cough and respiratory irritation can occur when mupirocin is administered by nasal spray.
