A variety of pharmaceutical preparations, which are applied in the management of non-infectious diseases, have shown in vitro some antimicrobial activity. These drugs are called "non-antibiotics". The aim of this study was to detect and characterise the antimicrobial activity of non-antibiotic drugs. selected from the preparations analysed during state control performed at the Drug Institute in Poland. Over 160 pharmaceutical preparations were randomly chosen from different groups of drugs. The surveillance study was performed on standard ATCC microbial strains used for drug control: S aureus, E. coil, P. aeruginosa and C. albicans. It was shown that the drugs listed below inhibited growth of at least one of the examined strains:acyclovir (Awirol 5%, cream), alendronate (Alenato 5 mg, tabl.), alverine (Meteospasmyl 20 mg, caps.), butorphanole (Butamidor 10 mg/ml, amp.), clodronate (Sindronat 400 mg, caps), diclofenac (Olfen 75 mg, amp.), emadastine (Emadine 0.05%, eye dr.), etodolac (Febret 200 mg, caps.), fluvastatine (Lescol 40 mg, tabl.), ketamine (Ketamidor 10%, amp.), levocabastine (Histimet 0.5 mg/ml, eye dr.), losartan (Lorista 50 mg, tabl.), matipranolol (Betaman 0.3% eye dr.), mesalazine (Pentasa 1%, susp.), naproxen (Nalgesin 550 mg, tabl.), oxaprosine (Reumax 600 mg, tabl.), oxymethazoline (Nasivin 0.025%, nose dr.), proxymetacaine (Alcaine 0.5%, eye dr.), ribavirin (Rebetol 200 mg, caps.), rutoside with ascorbic acid (Cerutin 20+200 mg, tabl.), sulodexide (Vessel due F, 250 LSU, caps.), tegaserole (Zelmac 50 mg, tabl.), telmisartan (Pritor 20 mg, tabl.), temosolomide (Temodal 100 mg, caps.), ticlopidine (Ticlid 250 mg, tabl.), tolfenamic acid (Migea rapid 200 mg, tabl.), tramadole (Tramundin 100 mg, tabl.), tropicamide (Tropicamidum 1%, eye dr.). Staphylococcus aureus was susceptible to most of the drugs listed above. Ticlopidine showed activity against S. aureus, E. coli and C. albicans (MICs equal to: 0.45; 0.45 and 0.65 mg/ml, respectively). Oxymetazoline showed activity against S. aureus and E. coli (MICs: 0.005 and 0.025 mg/ml, respectively). Pseudomonas aeruginosa was sensitive to alendronate, clondronate, oxaprozine, ribavirin and tramadole (MICs: 10, 63, 60, 3 and 43 mg/ml, respectively).

To test the concept that a replication-competent retrovirus carrying a suicide gene could have potential utility in the control of the natural virus infection in mammalian species, we constructed derivatives of a feline leukemia virus (FeLV) that is commonly associated with leukemia-lymphomas in this species. The FeLV, Rickard strain, subgroup A (FRA) genome contained at the 3' end of the envgene, an insert of an internal ribosomal entry site (IRES) linked to cDNA sequence of either herpes simplex virus thymidine kinase (HSV-TK) or a truncated HSV-TK (HSV-ATK) or yeast cytosine deaminase (CD). These constructs were transfected into feline fibroblast cells (H927). The viruses produced were determined to be replication-competent. The stable propagation of the full-length transgene was, however, dependent on the size of the insert, IRES-CD being the smallest in size (1031 bp) exhibiting maximal stability for at least up to six months. The protein products of the transgenes could be detected, despite the appearance of deleted proviruses at late passages. The transduced cells were susceptible to cytotoxic killing when the appropriate prodrug, ganciclovir (GCV), acyclovir (ACV) or 5-fluorocytosine (5-FC) was added to the culture medium. H927 cells, infected with another subgroup of FeLV, namely, FeLV-B or FeLV-C, could be superinfected by the FRA-suicide gene viruses and thus, subjected to killing. Interestingly, at an early stage of infection by the parental FRA, H927 cells could also be reinfected by the same subgroup FRA constructs to induce the suicide effect. Among the three constructs, the vector with the CD gene was determined to be superior to others in terms of stability, therapeutic index and bystander effect in the cell culture test system. While the in vivo correlates of the therapeutic effect in the feline model remain to be determined, our results do encourage investigation of the same concept in the control of HTLV and, perhaps even, HIV infection in humans.

Isolation and characterization of a sulfated polysaccharide from the brown alga Sargassum patens and determination of its anti-herpes activity.

Bioactivity-guided fractionation of the hot water extract from the brown alga Sargassun patens led to the isolation of a polysaccharide as an antiviral component against herpes simplex viruses which are the cause of cold sores (HSV-1) and genital herpes (HSV-2). The polysaccharide contained a sulfur group that could be present as a sulfate ester. It is thus a sulfated polysaccharide with a molecular mass of about 424 kDa, and is designated SP-2a. Gas chromatographic assay showed that the polysaccharide consisted of fucose, galactose, mannose, xylose, glucose, and galactosamine. The fucose is the major constituent sugar (35.3%), followed by galactose (18.4%). The 50% effective concentration (EC50) against HSV-2, HSV-1, and HSV-1 acyclovir resistant strain was 1.3, 5.5, and 4.1 microg/mL, respectively. The 50% cytotoxic concentration (CC50) of SP-2a on the growth of normal Vero cell line was more than 4000 microg/mL. Therefore SP-2a of S. patens may be a potent agent for treating HSV infections.
