Perphenazine: From D2 Biology to Host Defense
2026-09-23
Perphenazine is more than a dopamine D2 receptor antagonist: its polypharmacology, mitochondrial effects, opioid tolerance suppression, and emerging macrophage findings create a compelling translational research framework. This article connects receptor pharmacology with host-directed antibacterial research while defining the controls needed to distinguish target engagement from cellular stress.

Drosophila Keap1 Nuclear Condensates Under Oxidative Stress
2026-09-19
Ji and colleagues show that Drosophila Keap1 assembles stable nuclear foci after oxidative stress and identify its C-terminal intrinsically disordered regions as drivers of condensate formation. Domain deletions, live-cell imaging, FRAP, and in vitro reconstitution further indicate that the Kelch domain restrains this activity, providing a mechanistic link between Keap1 stress signaling and nuclear organization.

NADPH Oxidase ROS Activate LTCC in Neonatal Arteries
2026-09-18
This study shows that NADPH oxidase-derived reactive oxygen species promote contraction of saphenous arteries from early postnatal rats primarily by activating L-type voltage-gated Ca2+ channels, rather than through Rho-kinase, PKC, or Src-kinase signaling. Its pharmacological design separates pathways that contribute to contraction generally from those specifically required for the ROS-mediated component, providing a useful framework for interpreting vascular redox experiments.

Phenothiazines, ROS, and Macrophage Antibacterial Defense
2026-09-18
Qiu et al. show that phenothiazines strengthen macrophage defense against intracellular bacteria by increasing reactive oxygen species, lysosomal activity, and autophagy. The study positions perphenazine as a lead compound for host-directed antibacterial research, while also highlighting the need to separate immune effects from its established neuropharmacological actions.

Brinzolamide Nanoemulsions: Permeation and Ocular Safety
2026-09-17
The reference study developed and screened 12 brinzolamide nanoemulsions using an integrated workflow that combined ex vivo corneal permeation with retinal-cell viability and ocular irritation testing. Seven formulations outperformed a marketed suspension, while NE6B and NE4C showed the most favorable safety profile; Triacetin was among the least toxic excipients evaluated.
