AI Article Synopsis

  • * A previous study detailed Astex's method for screening compounds against Hsp90 and finding two effective "hits."
  • * This paper discusses how scientists optimized one lead molecule, 2,4-dihydroxybenzamide, and the strategies used to develop AT13387, which is now in clinical testing.

Article Abstract

Inhibitors of the molecular chaperone heat shock protein 90 (Hsp90) are currently generating significant interest in clinical development as potential treatments for cancer. In a preceding publication (DOI: 10.1021/jm100059d ) we describe Astex's approach to screening fragments against Hsp90 and the subsequent optimization of two hits into leads with inhibitory activities in the low nanomolar range. This paper describes the structure guided optimization of the 2,4-dihydroxybenzamide lead molecule 1 and details some of the drug discovery strategies employed in the identification of AT13387 (35), which has progressed through preclinical development and is currently being tested in man.

Heat shock protein A1A (HSPA1A) is a molecular chaperone crucial in cell survival. In addition to its cytosolic functions, HSPA1A translocates to heat-shocked and cancer cells' plasma membrane (PM). In cancer, PM-localized HSPA1A (mHSPA1A) is associated with increased tumor aggressiveness and therapeutic resistance, suggesting that preventing its membrane localization could have therapeutic value.

With a high mortality rate, colon cancer (CC) is the third most common malignant tumor worldwide. The primary causes are thought to be the high invasiveness and migration of CC cells. The functions of Golgi phosphoprotein 3 (GOLPH3), stress-induced phosphoprotein 1 (STIP1), and the signal transducer and activator of transcription 3 (STAT3) signaling pathway in the invasion and migration of CC cells were examined in this study.

The human body reacts to tissue damage by generating damage-associated molecular patterns (DAMPs) that activate sterile immune responses. To date, little is known about how DAMPs are removed to avoid excessive immune responses. Here, we show that proteasomal dysfunction induces the release of mitochondrial DNA (mtDNA) as a DAMP that activates the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon gene (STING) pathway and is subsequently degraded through the N-degron pathway.

We have shown that virus-specific CD4 and CD8 memory T cells (TM) induce autophagy after T cell receptor (TCR) engagement to provide free glutamine and fatty acids, including in people living with HIV-1 (PLWH). These nutrients fuel mitochondrial ATP generation through glutaminolysis and fatty acid oxidation (FAO) pathways, to fulfill the bioenergetic demands for optimal IL-21 and cytotoxic molecule production in CD4 and CD8 cells, respectively. Here, we expand our knowledge on how the metabolic events that occur in the mitochondria of virus-specific TM down-stream of the autophagy are regulated.

Chaperonin containing tailless complex polypeptide 1 (CCT) functions as a molecular chaperone and is essential for ensuring proper protein folding. Glucose-regulated protein 78 (GRP78/Bip), also a type of chaperone, not only assists in folding of proteins, but also facilitates the transportation of proteins into the endoplasmic reticulum (ER) via the Sec protein complex. In this study, we identified the CCTη of N.
