• GSK343: Selective EZH2 Inhibitor Guide

  2026-08-13

  GSK343 is a cell-permeable EZH2 inhibitor that competes with SAM and inhibits EZH2 methyltransferase activity at a reported IC50 of 4 nM. Its strongest documented use is as an in vitro tool for studying PRC2-dependent H3K27me3 regulation in cancer models, rather than as a validated in vivo therapeutic.

• Bradykinin B2 Receptors and Ileal Peristalsis

  2026-08-12

  Chan and Rudd showed that bradykinin inhibits the peristaltic reflex in the guinea pig isolated ileum through B2, rather than B1, kinin receptors. By measuring the pressure threshold required to initiate propulsion and testing selective agonists and antagonists, the study connected receptor pharmacology with an integrated gastrointestinal motor response.

• Estradiol, ER Stress, and CD4+ T Cells After Shock

  2026-08-12

  The reference study shows that estradiol restores splenic CD4+ T-cell proliferation and cytokine production after hemorrhagic shock by reducing endoplasmic reticulum stress through ERα- and GPR30-linked signaling. Its receptor-antagonist and ER-stress controls provide a useful framework for separating estrogen-receptor effects from downstream cellular stress responses.

• Tetrandrine Workflows for Ion Channel Research

  2026-08-11

  Build reproducible Tetrandrine experiments for calcium signaling, inflammation, and cell-based pharmacology with practical dosing, controls, and troubleshooting guidance. The workflow also shows how structure-based natural-product screening can inform assay selection without overstating antiviral evidence.

• LTI6426 Enhances Panobinostat in Myeloma

  2026-08-11

  This 2022 study identifies the protein disulfide isomerase inhibitor LTI6426 as a potential partner for low-dose panobinostat in multiple myeloma, including a proteasome inhibitor-resistant model. The combination increased antitumor activity in vitro and in vivo while converging on ER-stress markers ATF3, DDIT3/CHOP, and DNAJB1, which may support pharmacodynamic monitoring in future studies.

• AMG 9810: Reading TRPV1 Stress Signals

  2026-08-10

  AMG 9810 is a selective TRPV1 antagonist for separating receptor-proximal calcium and CGRP signals from broader metabolic-stress responses.

• Malate as a Flux Probe in Tumor Immunometabolism

  2026-08-09

  Malate is more than a tricarboxylic acid cycle intermediate: it can serve as a controlled perturbation for examining redox balance, mitochondrial flux, and tumor–macrophage signaling. This article develops an assay decision framework grounded in recent PDHA1 succinylation findings and practical product considerations.
