TPCA-1: Selective IKK-2 Inhibitor for NF-κB Research
2026-08-21
TPCA-1 is an IKK-2 inhibitor that suppresses NF-κB-dependent inflammatory signaling. Product data report nanomolar inhibition of LPS-induced cytokines in human monocytes and reduced disease severity in a collagen-induced arthritis mouse model.
Psora 4: Precision Kv1.3 Blocker Workflows
2026-08-20
Psora 4 supports mechanism-first studies of Kv1.3-dependent membrane potential, Ca2+ entry, and effector memory T-cell function. This workflow-focused guide shows how to pair electrophysiology with immune phenotyping while accounting for KCNE4-dependent changes in blocker kinetics.
Coumestrol: From Receptor Biology to Ferroptosis
2026-08-20
Coumestrol is a phytoestrogen estrogen receptor antagonist with distinctive activity across estrogen and xenobiotic-sensing receptors. This article presents a mechanism-triangulation framework connecting receptor pharmacology with ferroptosis and PMAIP1-dependent responses in rheumatoid arthritis research.
Bestatin and Angiotensin Signaling in Rat Brain
2026-08-19
Harding and Felix used complementary aminopeptidase inhibitors, peptide analogs, and iontophoretic electrophysiology to test whether angiotensin II must be converted to angiotensin III before activating neurons. Their results support an obligatory angiotensin II-to-III processing step in rat brain while distinguishing peptide formation from peptide degradation.
BMP4–GPX4 Protects RGCs in NMDA Glaucoma Model
2026-08-19
Fang and colleagues identify the BMP4–GPX4 axis as a mechanistic link between retinal ganglion cell ferroptosis and the performance of transplanted retinal stem cells in an NMDA-induced mouse glaucoma model. The findings connect reduced oxidative stress and iron accumulation with improved retinal stem cell survival and differentiation, while also highlighting important limits in translating a chemically induced injury model to chronic high-intraocular-pressure glaucoma.
Palomid 529: A Resistance-to-Pathway Lens
2026-08-18
Palomid 529 (P529) offers a dual mTORC1/mTORC2 approach for cancer research. This article connects its pathway-probing value to new findings on RCN2-driven ESCC metastasis and cisplatin resistance, emphasizing assay interpretation rather than another generic protocol.
Ibrexafungerp Against Echinocandin-Resistant Candida
2026-08-18
This study evaluates ibrexafungerp (MK 3118) against 192 clinically derived, phenotypically and genotypically echinocandin-resistant Candida isolates. By combining EUCAST broth microdilution, FKS hotspot sequencing, and wild-type upper-limit analysis, the authors show that activity is retained but varies by Candida species and mutation location.
L-Alanyl-L-Glutamine for Barrier Assays
2026-08-17
L-Alanyl-L-glutamine provides a water-soluble, stable format for intestinal barrier, mucosal stress, antioxidant, and inflammation studies. This workflow shows how to prepare fresh aqueous solutions, pair barrier measurements with orthogonal readouts, and avoid common interpretation and storage errors.
CLCC1 and Herpesvirus Nuclear Egress
2026-08-16
The bioRxiv study identifies the host protein CLCC1 as an essential factor in the membrane-fusion step of herpesvirus nuclear egress. A genome-wide CRISPR screen and cellular phenotyping connect CLCC1 loss with perinuclear capsid accumulation, reduced viral production, and defective nuclear pore insertion, revealing a potentially ancient membrane-remodeling mechanism.
Masitinib (AB1010): KIT/PDGFR Workflow Guide
2026-08-15
Masitinib (AB1010), SKU A2942, is a DMSO-soluble phenylaminothiazole-type tyrosine kinase inhibitor for focused KIT and PDGFRα/β research. It is suitable for biochemical, cellular, GIST, mast cell, and mastocytosis research workflows, but not for assays requiring aqueous or ethanol solubility or broad-spectrum kinase inhibition.
Topotecan (SKF104864) in Cancer Research
2026-08-15
Topotecan (SKF104864) enables mechanism-driven studies of topoisomerase I inhibition, apoptosis induction in glioma cells, and treatment response in pediatric solid tumor models. This workflow-focused guide connects reproducible in vitro assays with combination testing, translational interpretation, and practical troubleshooting.
Tacrine hydrochloride hydrate: Assay Workflows
2026-08-14
Build more interpretable cholinesterase inhibition and neuronal protection experiments with Tacrine hydrochloride hydrate, from concentration control to orthogonal validation. The workflow also adapts a metabolism-study mindset: test alternative explanations instead of assuming that one pathway accounts for every signal.
CFTRinh-172 Workflows for Epithelial Transport
2026-08-14
CFTRinh-172 provides rapid, selective functional suppression of CFTR for epithelial transport, trafficking, and disease-model assays. This guide connects short-term channel inhibition with surface-abundance measurements, helping researchers distinguish altered CFTR activity from altered membrane localization.
Nicotinamide Riboside Chloride in RGC Models
2026-08-13
Nicotinamide Riboside Chloride (NIAGEN) adds a controllable NAD+ metabolism variable to chemically defined retinal ganglion cell workflows. This guide shows how to integrate it into iPSC-derived RGC studies, separate metabolic effects from differentiation effects, and troubleshoot dosing, stability, and assay variability.
