Frontiers in Anti-Infective Agents is a book series that focuses on antibiotics and vaccines, both current and new.

The series is essential reading for general readers, healthcare professionals, researchers and academicians actively involved in research on infectious diseases and anti-infective therapeutic drugs.

The first volume is a comprehensive documentation on major infectious diseases from tropical countries which pose a serious threat to global healthcare programs. These include diseases such as tuberculosis, AIDS, leishmaniasis (kala-azar), elephantiasis, malaria, leprosy, various fungal disorders and emergent viral diseases. Due to the widespread use of antibiotics, there is an emergence of drug resistant pathogens in many regions. Hence, there is a need to search for novel, cost-effective bioactive compounds that demonstrate high efficacy and low toxicity in human cells from unexplored ecosystems to combat emerging drug resistant pathogens. Chapters written for this volume focus on the pathogenesis and etiology of each of the mentioned diseases, updated WHO reports wherever applicable, conventional drugs and their pharmacokinetics as well as new approaches to develop anti-infective agents.

The authors also present a detailed report on multi-drug resistant pathogens (‘superbugs’) and new measures being taken up to eradicate them. Information about new antimicrobials (bioactive peptides and silk protein sericin) and the approaches taken by scientists and healthcare professionals for successful targeting of these molecules for human medicine.

OPEN ACCESS ARTICLE – Sulfonamides as Inhibitors of Leishmania – Anti-Infective Agents

Journal: Anti-Infective Agents

Author(s): Jade Katinas*, Rachel Epplin, Christopher Hamaker, Marjorie A. Jones

Graphical Abstract:

 

Abstract:

Introduction: Leishmaniasis is an endemic disease caused by the protozoan parasite Leishmania. Current treatments for the parasite are limited by cost, availability and drug resistance as the occurrence of leishmaniasis continues to be more prevalent. Sulfonamides are a class of compounds with medicinal properties which have been used to treat bacterial and parasitic disease via various pathways especially as antimetabolites for folic acid.

Methods: New derivatives of sulfonamide compounds were assessed for their impact on Leishmania cell viability and potential pathways for inhibition were evaluated. Leishmania tarentolae (ATCC Strain 30143) axenic promastigote cells were grown in brain heart infusion (BHI) medium and treated with varying concentrations of the new sulfonamide compounds. Light microscopy and viability tests were used to assess the cells with and without treatment.

Discussion: A non-water soluble sulfonamide was determined to have 90-96% viability inhibition 24 hours after treatment with 100 μM final concentration. Because Leishmania are also autotrophs for folate precursors, the folic acid pathway was identified as a target for sulfonamide inhibition. When folic acid was added to untreated Leishmania, cell proliferation increased. A water soluble derivative of the inhibitory sulfonamide was synthesized and evaluated, resulting in less viability inhibition with a single dose (approximately 70% viability inhibition after 24 hours with 100 μM final concentration), but additive inhibition with multiple doses of the compound.
Results: However, the potential mechanism of inhibition was different between the water-soluble and non-water soluble sulfonamides. The inhibitory effects and potential pathways of inhibition indicate that these compounds may be new treatments for this disease.

 

EDITOR’S CHOICE – Neoflavonoids as Prospective Compounds Against Parasitic Neglected Tropical Infections and Human Immunodeficiency Virus – Current Bioactive Compounds

Journal: Current Bioactive Compounds 

Author(s): Gláucio B. Saldanha, George L.S. Oliveira, José C.C.L. da Silva, Maria C.P. Oliveira, Ana P.S.C.L. da Silva*, Juceni P. de Lima David

Graphical Abstract:

 

Abstract:

Background: Neoflavonoids comprise a group of compounds that have a C6-C3-C6 carbon skeleton and that naturally occur in higher plants from families Clusiaceae, Leguminosae, Rubiaceae, Passifloraceae, Asteraceae and Rutaceae.

Objective: Neoflavonoids have drawn great interest lately due to their pharmacological and biochemical properties found in vitro and in vivo studies, which is attributed to the pattern of substitutions found in their basic chemical structure.

Methods: This review was prepared by analyzing articles selected from Science Direct, Scopus, Pub Med, Web of Science and SciFinder.
Results: Among other pharmacological activities, in vitro and in vivo studies have highlighted these compounds as promising bioactive molecules in the treatment of some parasitic neglected tropical infections (NTIs) such as malaria, leishmaniasis and American trypanosomiasis (Chagas Disease). Neoflavonoids have also showed activity against HIV-1 (human immunodeficiency virus type 1), and have been used to develop new molecules for the treatment of HIV/AIDS.
Conclusion: Therefore, a more intensive research of neoflavonoids can provide inputs to discover and develop alternative therapies from new bioactive molecules. Thus, this review summarizes the results of studies involving neoflavonoids and their derivatives with therapeutic implications in the treatment of NTIs and HIV.
