Novel hybrid conjugates with dual estrogen receptor α degradation and histone deacetylase inhibitory activities for breast cancer therapy.

Bioorg Med Chem 2021 May 1;40:116185. Epub 2021 May 1.

Hubei Key Laboratory of Cell Homeostasis, College of Life Sciences, Wuhan University, Wuhan 430072, China. Electronic address:

Hormone therapy targeting estrogen receptors is widely used clinically for the treatment of breast cancer, such as tamoxifen, but most of them are partial agonists, which can cause serious side effects after long-term use. The use of selective estrogen receptor down-regulators (SERDs) may be an effective alternative to breast cancer therapy by directly degrading ERα protein to shut down ERα signaling. However, the solely clinically used SERD fulvestrant, is low orally bioavailable and requires intravenous injection, which severely limits its clinical application. Read More

Departamento de Química, Universidade Federal de Minas Gerais, Avenida Antônio Carlos, 6627, Belo Horizonte (MG) 31270-901, Brazil.

This paper reports on the synthesis and characterization of two new polypyridyl-hydrazone Schiff bases, ()-'-(6-oxo-1,10-phenanthrolin-5(6)-ylidene)thiophene-2-carbohydrazide () and ()-'-(6-oxo-1,10-phenanthrolin-5(6)-ylidene)furan-2-carbohydrazide (), and their two Ru(II) complexes of the general formula [RuCl(DMSO)(phen)(L)](PF6). Considering that hydrazides are a structural part of severa l drugs and metal complexes containing phenanthroline derivatives are known to interact with DNA and to exhibit antitumor activity, more potent anticancer agents can be obtained by covalently linking the thiophene acid hydrazide or the furoic acid hydrazide to a 1,10-phenanthroline moiety. These ligands and the Ru(II) complexes were characterized by elemental analyses, electronic, vibrational, H NMR, and ESI-MS spectroscopies. Read More

Discovery of a Potent Degrader for Fibroblast Growth Factor Receptor 1/2.

Angew Chem Int Ed Engl 2021 Apr 29. Epub 2021 Apr 29.

Harvard Medical School, Dana Farber Cancer Institute, 360 Longwood Avenue, 2115, Boston, UNITED STATES.

Aberrant activation of FGFR signaling occurs in many cancers, and ATP-competitive FGFR inhibitors have received regulatory approval. Despite demonstrating clinical efficacy, these inhibitors exhibit dose-limiting toxicity, potentially due to a lack of selectivity amongst the FGFR family and are poorly tolerated. Here, we report the discovery and characterization of DGY-09-192, a bivalent degrader that couples the pan-FGFR inhibitor BGJ398 to a CRL2 VHL E3 ligase recruiting ligand, which preferentially induces FGFR1&2 degradation while largely sparing FGFR3&4.
