AI Article Synopsis

  • Hsp90 is an important chaperone overexpressed in many cancers, making it a key target for drug discovery.
  • Novobiocin, an antibiotic, has been shown to inhibit Hsp90 and exhibits anti-cancer properties, prompting the development of better compounds.
  • A new series of novobiocin analogs were created, tested on breast cancer cell lines, and analyzed for their effects on cell cycle progression, apoptosis, and Hsp90 client protein degradation.

Article Abstract

Hsp90 is an ATP-dependent chaperone known to be overexpressed in many cancers. This way, Hsp90 is an important target for drug discovery. Novobiocin, an aminocoumarin antibiotic, was reported to inhibit Hsp90 targeting C-terminal domain, and showed anti-proliferative properties, leading to the development of new and more active compounds. Consequently, a new set of novobiocin analogs derived from 1,6-naphthyridin-2(1H)-one scaffold was designed, synthesized and evaluated against two breast cancer cell lines. Subsequently, cell cycle progression and apoptosis were conducted on best candidates, finally Western Blot analysis was performed to measure their ability to induce degradation of Hsp90 client proteins.

Neuronal inclusions of hyperphosphorylated TDP-43 are hallmarks of disease for most patients with amyotrophic lateral sclerosis (ALS). Mutations in TARDBP, the gene coding for TDP-43, can cause some cases of familial inherited ALS (fALS), indicating dysfunction of TDP-43 drives disease. Aggregated, phosphorylated TDP-43 may contribute to disease phenotypes; alternatively, TDP-43 aggregation may be a protective cellular response sequestering toxic protein away from the rest of the cell.

As many proteins prioritize functionality over constancy of structure, a proteome is the shortest stave in the Liebig's barrel of cell sustainability. In this regard, both prokaryotes and eukaryotes possess abundant machinery supporting the quality of the proteome in healthy and stressful conditions. This machinery, namely chaperones, assists in folding, refolding, and the utilization of client proteins.

Sustained myocardial hypertrophy or left ventricular hypertrophy (LVH) triggered by pressure overload is strongly linked to adverse cardiovascular outcomes. Here, we investigated the clinical relationship between serum HSP90α (an isoform of HSP90) levels and LVH in patients with hypertension or aortic stenosis (AS) and explored underlying mechanisms in pressure overload mouse model. We built a pressure overload mouse model via transverse aortic constriction (TAC).

Background: Processing methods of traditional Chinese medicinal materials are critical in influencing the active metabolites and pharmacological effects. The fresh processing method effectively prevents the loss and degradation of metabolites, common in traditional drying and softening processes, while also reducing production costs. (AR), a leguminous botanical drug, is widely utilized in clinical practice and functional foods.

In esophageal squamous cell carcinoma, genetic activation of NRF2 increases resistance to chemotherapy and radiotherapy, which results in a significantly worse prognosis for patients. Therefore NRF2-activated cancers create an urgent clinical need to identify new therapeutic options. In this context, we previously identified the geldanamycin family of HSP90 inhibitors, which includes 17DMAG, to be synthetic lethal with NRF2 activity.
