Cryptosporidium AdhE Inhibition by Antifungal Imidazoles
2026-09-15
The reference study establishes the bacterial-type bifunctional aldehyde/alcohol dehydrogenase CpAdhE as a chemically vulnerable metabolic target in Cryptosporidium parvum. Through library screening, enzyme kinetics, parasite growth assays, and cytotoxicity testing, the authors show that several antifungal imidazoles have low-micromolar activity and provide a rationale for further anti-cryptosporidial drug discovery.

Foretinib, Immunogenic Cell Death, and CD47 Blockade
2026-09-14
The reference study shows that foretinib, a c-Met/VEGFR2 inhibitor, can induce immunogenic cell death in colorectal cancer by activating p53, increasing DR5, and promoting calreticulin exposure, ATP release, and HMGB1 secretion. These effects remodel the tumor immune microenvironment and help explain the enhanced antitumor activity observed when foretinib is combined with anti-CD47 immunotherapy.

LGMN Editing with Cas9 mRNA Represses Metastasis
2026-09-14
Wang and colleagues developed a lipid nanoparticle strategy for co-delivering Cas9 mRNA and guide RNA to disrupt LGMN, a lysosomal protease associated with aggressive breast cancer behavior. The study links this editing workflow to impaired lysosomal/autophagic degradation and reduced cancer-cell clonogenicity, migration, invasion, and experimental lung metastasis, while also offering practical lessons for T7-promoter-driven RNA production.

Mecamylamine Hydrochloride: Causal nAChR Tests
2026-09-13
Mecamylamine hydrochloride offers a reversible pharmacological way to test whether nicotinic signaling contributes to gut-brain and neuropsychiatric phenotypes. This article develops a causal assay framework grounded in recent Bacteroides fragilis epilepsy research while defining what the antagonist can—and cannot—prove.

ACSL1, FSP1, and Ferroptosis in Ovarian Cancer
2026-09-11
The reference study identifies an ACSL1–FSP1 axis that links fatty-acid metabolism to ferroptosis resistance and platinum failure in ovarian cancer spheroids. Its central innovation is showing that ACSL1 promotes FSP1 N-myristoylation, stability, and membrane localization, thereby strengthening antioxidant defense against lipid peroxidation.

LC–MS/MS Maps GS-441524 Prodrug Conversion
2026-09-11
A January 2026 Microchemical Journal study established an LC–MS/MS strategy for tracing conversion of the novel GS-441524 prodrug NGP-1 across gastric, hepatic, blood, and in vivo systems. Its findings show that NGP-1 can release GS-441524 at several stages after administration, highlighting why parent and released metabolite should be measured together in antiviral pharmacokinetic studies.

Honokiol-Induced Paraptosis in Acute Promyelocytic Leukemia
2026-09-10
Liu and colleagues showed that honokiol kills NB4 acute promyelocytic leukemia cells through a paraptosis-like, largely nonapoptotic process involving reactive oxygen species, mitochondrial injury, endoplasmic reticulum stress, proteasome dysfunction, and mTOR/MAPK signaling. The study provides a mechanistic framework for evaluating nonapoptotic leukemia-cell death and illustrates how pharmacologic pathway perturbation can distinguish autophagy-related markers from true autophagic flux.
