Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications
International Journal of Molecular Sciences Review Folic Acid Antagonists: Antimicrobial and Immunomodulating Mechanisms and Applications Daniel Fernández-Villa 1, Maria Rosa Aguilar 1,2 and Luis Rojo 1,2,* 1 Instituto de Ciencia y Tecnología de Polímeros, Consejo Superior de Investigaciones Científicas, CSIC, 28006 Madrid, Spain; [email protected] (D.F.-V.); [email protected] (M.R.A.) 2 Consorcio Centro de Investigación Biomédica en Red de Bioingeniería, Biomateriales y Nanomedicina, 28029 Madrid, Spain * Correspondence: [email protected]; Tel.: +34-915-622-900 Received: 18 September 2019; Accepted: 7 October 2019; Published: 9 October 2019 Abstract: Bacterial, protozoan and other microbial infections share an accelerated metabolic rate. In order to ensure a proper functioning of cell replication and proteins and nucleic acids synthesis processes, folate metabolism rate is also increased in these cases. For this reason, folic acid antagonists have been used since their discovery to treat different kinds of microbial infections, taking advantage of this metabolic difference when compared with human cells. However, resistances to these compounds have emerged since then and only combined therapies are currently used in clinic. In addition, some of these compounds have been found to have an immunomodulatory behavior that allows clinicians using them as anti-inflammatory or immunosuppressive drugs. Therefore, the aim of this review is to provide an updated state-of-the-art on the use of antifolates as antibacterial and immunomodulating agents in the clinical setting, as well as to present their action mechanisms and currently investigated biomedical applications.

FLAMAZINE™ CREAM 1.0% W/W
PRODUCT INFORMATION NAME OF THE MEDICINE: FLAMAZINE™ CREAM 1.0% w/w Silver sulfadiazine 1% w/w Composition: Active ingredient. Silver sulfadiazine. Excipients. Polysorbate 60 Ph. Eur, Polysorbate 80 Ph. Eur, Glyceryl Monostearate Ph. Eur, Cetyl Alcohol Ph. Eur, Liquid Paraffin Ph. Eur, Propylene Glycol Ph. Eur and Purified Water Ph. Eur. DESCRIPTION: A sterile white hydrophilic cream containing silver sulfadiazine 1%. The cream is a semisolid oil-in-water emulsion. The silver sulfadiazine is in a fine micronised form. Silver sulfadiazine is a white or creamy-white, odourless or almost odourless crystalline powder, which becomes yellow on exposure to light. Practically insoluble in water; slightly soluble in acetone; practically insoluble in alcohol, chloroform or ether; freely soluble in strong ammonia solution. Chemical name: Silver salt of N’-(pyrimidin-2-yl)sulfanilamide. C10H9AgN4O2S. M.W. 357.1 CAS 22199-08-2 Chemical structure: PHARMACOLOGY: Silver sulfadiazine is a sulfonamide and has broad antimicrobial activity against both Gram- positive and Gram-negative organisms. Silver sulfadiazine acts on the cell membrane and cell wall. Unlike sulfadiazine or other sulfonamides, the antibacterial action of the silver salt of sulfadiazine does not appear to depend on inhibition of folic acid synthesis. Its action is not antagonised by p-aminobenzoic acid. Flamazine Cream: 1 June 2010 1 of 6 Microbiology: Silver sulfadiazine has broad antimicrobial activity against both Gram-positive and Gram-negative organisms including Pseudomonas aeruginosa, some yeasts and fungi. It has also been reported to be active in vitro against herpes virus and Treponema pallidum. Sulfonamides act by interfering with the synthesis of nucleic acids in sensitive micro- organisms by blocking the conversion of p- aminobenzoic acid to the co-enzyme dihydrofolic acid. -

The exact mechanism of action of glucocorticosteroids in the treatment of Crohn’s disease is not fully understood. Anti-inflammatory actions, such as the inhibition of inflammatory mediator release and inhibition of immunological cellular responses, are probably important. Data from clinical pharmacology studies and controlled clinical trials indicate that ENTOCORT capsules, at least partly, act topically. Budesonide undergoes an extensive degree (approximately 90%) of biotransformation in the liver to metabolites with low glucocorticosteroid activity. The glucocorticosteroid activity of the major metabolites, 6β- hydroxybudesonide and 16α-hydroxyprednisolone, is less than 1% of that of budesonide. The metabolism of budesonide is primarily mediated by CYP 3A4, an isozyme of cytochrome P450. The favourable separation between topical anti-inflammatory and systemic effect is due to strong glucocorticosteroid receptor affinity and an effective first pass metabolism by the liver with a short half-life. A glucocorticosteroid with such a profile is of particular importance for the local treatment of inflammatory bowel diseases such as Crohn’s disease. -

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria. -

Sulfonamides and Sulfonamide Combinations*
Sulfonamides and Sulfonamide Combinations* Overview Due to low cost and relative efficacy against many common bacterial infections, sulfonamides and sulfonamide combinations with diaminopyrimidines are some of the most common antibacterial agents utilized in veterinary medicine. The sulfonamides are derived from sulfanilamide. These chemicals are structural analogues of ρ-aminobenzoic acid (PABA). All sulfonamides are characterized by the same chemical nucleus. Functional groups are added to the amino group or substitutions made on the amino group to facilitate varying chemical, physical and pharmacologic properties and antibacterial spectra. Most sulfonamides are too alkaline for routine parenteral use. Therefore the drug is most commonly administered orally except in life threatening systemic infections. However, sulfonamide preparations can be administered orally, intramuscularly, intravenously, intraperitoneally, intrauterally and topically. Sulfonamides are effective against Gram-positive and Gram-negative bacteria. Some protozoa, such as coccidians, Toxoplasma species and plasmodia, are generally sensitive. Chlamydia, Nocardia and Actinomyces species are also sensitive. Veterinary diseases commonly treated by sulfonamides are actinobacillosis, coccidioidosis, mastitis, metritis, colibacillosis, pododermatitis, polyarthritis, respiratory infections and toxo- plasmosis. Strains of rickettsiae, Pseudomonas, Klebsiella, Proteus, Clostridium and Leptospira species are often highly resistant. Sulfonamides are bacteriostatic antimicrobials
