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. Keywords: folic acid antagonists; antifolates; antibiotics; antibacterials; immunomodulation; sulfonamides; antimalarial 1. -
Sequence Variation in the Dihydrofolate Reductase-Thymidylate Synthase (DHFR-TS) and Trypanothione Reductase (TR) Genes of Trypanosoma Cruzi
Molecular & Biochemical Parasitology 121 (2002) 33Á/47 www.parasitology-online.com Sequence variation in the dihydrofolate reductase-thymidylate synthase (DHFR-TS) and trypanothione reductase (TR) genes of Trypanosoma cruzi Carlos A. Machado *, Francisco J. Ayala Department of Ecology and Evolutionary Biology, University of California, Irvine, CA 92697-2525, USA Received 15 November 2001; received in revised form 25 January 2002 Abstract Dihydrofolate reductase-thymidylate synthase (DHFR-TS) and trypanothione reductase (TR) are important enzymes for the metabolism of protozoan parasites from the family Trypanosomatidae (e.g. Trypanosoma spp., Leishmania spp.) that are targets of current drug-design studies. Very limited information exists on the levels of genetic polymorphism of these enzymes in natural populations of any trypanosomatid parasite. We present results of a survey of nucleotide variation in the genes coding for those enzymes in a large sample of strains from Trypanosoma cruzi, the agent of Chagas’ disease. We discuss the results from an evolutionary perspective. A sample of 31 strains show 39 silent and five amino acid polymorphisms in DHFR-TS, and 35 silent and 11 amino acid polymorphisms in TR. No amino acid replacements occur in regions that are important for the enzymatic activity of these proteins, but some polymorphisms occur in sites previously assumed to be invariant. The sequences from both genes cluster in four major groups, a result that is not fully consistent with the current classification of T. cruzi in two major groups of strains. Most polymorphisms correspond to fixed differences among the four sequence groups. Two tests of neutrality show that there is no evidence of adaptivedivergence or of selectiveevents having shaped the distribution of polymorphisms and fixed differences in these genes in T. -

Academic Editors: Simona Collina and Mariarosaria Miloso Received: 25 February 2019; Accepted: 20 March 2019; Published: 22 March 2019 Abstract: Dihydrofolate reductase inhibitors are an important class of drugs, as evidenced by their use as antibacterial, antimalarial, antifungal, and anticancer agents. Progress in understanding the biochemical basis of mechanisms responsible for enzyme selectivity and antiproliferative effects has renewed the interest in antifolates for cancer chemotherapy and prompted the medicinal chemistry community to develop novel and selective human DHFR inhibitors, thus leading to a new generation of DHFR inhibitors. This work summarizes the mechanism of action, chemical, and anticancer profile of the DHFR inhibitors discovered in the last six years. New strategies in DHFR drug discovery are also provided, in order to thoroughly delineate the current landscape for medicinal chemists interested in furthering this study in the anticancer field. -

NADPH Homeostasis in Cancer: Functions, Mechanisms and Therapeutic Implications
Signal Transduction and Targeted Therapy www.nature.com/sigtrans REVIEW ARTICLE OPEN NADPH homeostasis in cancer: functions, mechanisms and therapeutic implications Huai-Qiang Ju 1,2, Jin-Fei Lin1, Tian Tian1, Dan Xie 1 and Rui-Hua Xu 1,2 Nicotinamide adenine dinucleotide phosphate (NADPH) is an essential electron donor in all organisms, and provides the reducing power for anabolic reactions and redox balance. NADPH homeostasis is regulated by varied signaling pathways and several metabolic enzymes that undergo adaptive alteration in cancer cells. The metabolic reprogramming of NADPH renders cancer cells both highly dependent on this metabolic network for antioxidant capacity and more susceptible to oxidative stress. Modulating the unique NADPH homeostasis of cancer cells might be an effective strategy to eliminate these cells. In this review, we summarize the current existing literatures on NADPH homeostasis, including its biological functions, regulatory mechanisms and the corresponding therapeutic interventions in human cancers, providing insights into therapeutic implications of targeting NADPH metabolism and the associated mechanism for cancer therapy.

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
