DEAF1, Adriamycin Resistance, and Pyroptosis in Myeloma
2026-08-23
A 2026 Drug Resistance Updates study identifies DEAF1 as a transcriptional regulator that protects multiple myeloma cells from adriamycin-induced apoptosis and pyroptosis. The work connects DEAF1 to RAD50–ATM-mediated DNA damage repair and the FER/GSDME pyroptotic pathway, while indicating that celastrol can enhance adriamycin activity by disrupting DEAF1 transcriptional interactions.

Sulfaphenazole-Derived Sulfonamides for TB
2026-08-21
Chen and colleagues used sulfaphenazole as a starting point for systematic sulfonamide optimization against Mycobacterium tuberculosis while targeting its CYP2C9 liability. Compound 10d combined reported antimycobacterial activity with weak CYP2C9 inhibition, providing a useful medicinal-chemistry precedent for balancing efficacy and drug–drug interaction risk.

L. plantarum P101, AMPK, and Alcoholic Fatty Liver
2026-08-20
This 2025 study shows that Lactiplantibacillus plantarum P101 reduced alcohol-induced hepatic lipid accumulation in mice, with evidence that AMPK activation was required for the protective phenotype. By combining pharmacological pathway inhibition with gut microbiota profiling and serum metabolomics, the work connects probiotic intervention to a gut–liver metabolic mechanism while identifying candidate microbial and metabolite correlates.

Clarithromycin as a CYP3A Inhibitor
2026-08-18
Use Clarithromycin as a controlled CYP3A perturbation tool for enzyme assays, pharmacokinetic studies, and statin metabolism interaction experiments. This workflow pairs concentration-resolved inhibition with a CYP-independent comparator to separate pathway effects from broader changes in drug disposition.

NADPH Oxidase ROS Activate L-Type Ca2+ Channels
2026-08-18
This study identifies L-type voltage-gated Ca2+ channels as the principal downstream route by which NADPH oxidase-derived ROS promote arterial contraction in early postnatal rats. Pharmacological comparisons show that Rho-kinase, PKC, and Src-kinase contribute to methoxamine contraction but are not required for the specific procontractile effect of NADPH oxidase-derived ROS.

Steroid Lysis of Protoplasts: Methods and Findings
2026-08-17
The 1965 study by Smith and Shay used lysozyme-generated Sarcina lutea protoplasts to distinguish steroid-associated membrane damage from effects involving the bacterial cell wall. Its protection experiments with polyamines, metal ions, uranyl nitrate, and surfactants provide a useful framework for interpreting membrane-lysis assays while highlighting the limits of inferring mechanism from optical readouts alone.

ERK5 in Vitamin D–Induced Myeloid Differentiation
2026-08-15
Wang et al. show that ERK5 and ERK1/2 make distinct contributions to 1α,25-(OH)2 vitamin D3-induced differentiation of HL60 and U937 myeloid leukemia cells. ERK5 inhibition altered CD11b and CD14 expression while producing cell-cycle arrest, revealing pathway-specific control that is not captured by treating MAPK signaling as a single linear module.
