  Dihydropteroate synthase (DHPS) is an enzyme of the folate biosynthesis pathway, which catalyzes the formation of 7,8‐dihydropteroate (DHPt) from 6‐hydroxymethyl‐7,8‐dihydropterin pyrophosphate (DHPPP) and para‐aminobenzoic acid (pABA). DHPS is the long‐standing target of the sulfonamide class of antibiotics that compete with pABA. In the wake of sulfa drug resistance, targeting the structurally rigid

  二氢蝶呤合酶（DHPS）是叶酸生物合成途径中的一种酶，可催化6-羟甲基-7,8-二氢蝶呤焦磷酸（DHPPP）和对氨基苯甲酸（pABA）形成7,8-二氢蝶呤（DHPt）。DHPS是与pABA竞争的磺胺类抗生素的长期目标。在对磺胺类药物产生抗药性之后，已经提出了针对结构刚性（且更保守）的蝶呤位点作为抑制野生型和磺胺类药物耐药菌株中DHPS的替代策略。在开发相邻酶6-羟甲基-7,8-二氢蝶呤焦磷酸激酶（HPPK）的蝶呤位点抑制剂后，我们现在提供8-巯基鸟嘌呤的衍生物，该片段在两种酶中均弱结合，并定量亚μ米使用表面等离振子共振（SPR）结合大肠杆菌DHPS（EcDHPS）。十一个与配体结合的EcDHPS晶体结构描绘了观察到的结构-活性关系，为合理开发新型的，与底物-信封相容的DHPS抑制剂提供了结构框架。

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

  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.
