  The discovery of purine-based agents targeting triple-negative breast cancer and the αB-crystallin/VEGF protein–protein interaction

  摘要：

  Oestrogen receptor-negative breast cancer, particularly subtypes such as triple-negative breast cancer (TNBC, around 10-15% of cases), are characterised by poor long-term survival, poor response to therapy and early progression to metastasis. Purine-based compounds represent a privileged scaffold in anticancer drug design, with several clinically approved and experimental agents in clinical development comprising a purine core structure. In this study, a series of new purine-based compounds were synthesised; seven of the new analogues were found to significantly reduce the in vitro viability of TNBC cell lines (MDA-MB-231 and MDA-MB-436) with IC50 values of 50M. In previous work, we have proposed a new concept for targeting angiogenesis driving TNBC progression, by disrupting the protein-protein interaction between the molecular chaperone B-crystallin (CRYAB) and VEGF. Since previous clinical studies applying anti-VEGF therapy to TNBC patients have met with limited success, we were interested to test our most promising purine analogues against CRYAB/VEGF, using a custom-designed cell-based CRYAB/VEGF(165) interaction assay platform. Analogues 4e and 4f significantly reduced the interaction between CRYAB/VEGF(165), and compound 4e (100M) was also found to decrease the levels of soluble VEGF expressed by MDA-MB-231 cells by 40%. In conclusion, these promising early activity profiles warrant further investigation to validate this concept.

  8-Bromination of 2,6,9-trisubstituted purines with pyridinium tribromide

  摘要：

  2,6,9-Trisubstituted purines are brominated in high yields using pyridinium tribromide as the brominating reagent. This procedure works excellently for electron-rich purines having electron-donating substituents at the 2- and 6-positions. The use of pyridinium tribromide, a crystalline alternative to elemental bromine, improves the bromination procedure for this type of substrate as the reagent is easy to handle and the work-up and purification procedures are simplified.
