Analogs of 5-methylthioribose, a novel class of antiprotozoal agents [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1988
Since drug resistance and toxicity limit the use of available antiprotozoal agents, it is important that new drugs be developed as soon as possible. In this study, the method by which several protozoa degrade 5'-methylthioadenosine (MTA) was shown to differ from MTA catabolism in human cells.

A Review of the Control of Coccidiosis in Poultry Using Natural Additives, Focusing on Gut Health and Immunity

open access: yesAdvances in Agriculture, Volume 2026, Issue 1, 2026.
Coccidiosis is one of the most common diseases in the poultry industry worldwide (especially in broilers aged 3–6 weeks), causing significant economic losses to poultry farmers and governments every year. Conventional methods (anticoccidial chemical compounds) for the coccidiosis debarment and control always present challenges and disadvantages, such ...

Acyclic Nucleoside Phosphonates As Potential Inhibitors of Plasmodium Falciparum Egress

open access: yesChemistry – A European Journal, Volume 31, Issue 69, December 9, 2025.
Exploration of the chemistry of acyclic nucleoside phosphonates allowed us to study structural diversity from the hit compound; biological evaluation and molecular docking were performed to decipher key interactions with the putative target. Abstract The emergence of drug‐resistant Plasmodium strains requires the development of novel antimalarial ...

SIP‐SRS Imaging of Cell Wall Synthesis Identifies a Synergy between Micafungin and Amphotericin B

open access: yesAdvanced Science, Volume 12, Issue 48, December 29, 2025.
We employed glucose‐d7–based stable isotope probe‐assisted SRS microscopy (SIP‐SRS) C–D imaging to visualize fungal cell wall synthesis and remodeling under antifungal treatment. Amphotericin B (AmB) induced notable daughter cell wall thickening, prompting a combinational therapy with AmB and micafungin.
