  The development of a new class of inhibitors for betaine-homocysteine S-methyltransferase

  摘要：

  Betaine-homocysteine S-methyltransferase (BHMT) is an important zinc-dependent methyltransferase that uses betaine as the methyl donor for the remethylation of homocysteine to form methionine. In the liver, BHMT performs to half of the homocysteine remethylation. In this study, we systematically investigated the tolerance of the enzyme for modifications at the "homocysteine" part of the previously reported potent inhibitor (R,S)-5-(3-amino-3-carboxy-propylsulfanyl)-pentanoic acid (1). In the new compounds, which are S-alkylated homocysteine derivatives, we replaced the carboxylic group in the "homocysteine" part of inhibitor 1 with different isosteric moieties (tetrazole and oxadiazolone); we suppressed the carboxylic negative charge by amidations; we enhanced acidity by replacing the carboxylate with phosphonic or phosphinic acids; and we introduced pyrrolidine steric constraints. Some of these compounds display high affinity toward human BHMT and may be useful for further pharmacological studies of this enzyme. Although none of the new compounds were more potent inhibitors than the reference inhibitor 1, this study helped to completely define the structural requirements of the active site of BHMT and revealed the remarkable selectivity of the enzyme for homocysteine.

  The estrogen receptor (ER) is a validated target for the treatment of estrogen receptor-positive (ER+) breast cancer. Here, we describe the design, synthesis, and extensive structure-activity relationship (SAR) studies of small-molecule ERα degraders based on the proteolysis targeting chimeras (PROTAC) concept. Our efforts have resulted in the discovery of highly potent and effective PROTAC ER degraders

  雌激素受体（ER）是治疗雌激素受体阳性（ER+）乳腺癌的有效靶点。在这里，我们描述了基于蛋白水解靶向嵌合体 (PROTAC) 概念的小分子 ERα 降解剂的设计、合成和广泛的构效关系 (SAR) 研究。我们的努力导致发现了高效和有效的 PROTAC ER 降解剂，例如 ERD-308 (32)。ERD-308 在 MCF-7 和 T47D ER+ 乳腺癌细胞系中分别达到 0.17 和 0.43 nM 的 DC50（导致 50% 蛋白质降解的浓度）值，并在低至 5 nM 的浓度下诱导 >95% 的 ER 降解两种细胞系。值得注意的是，ERD-308 比氟维司群诱导更完全的 ER 降解，氟维司群是唯一批准的选择性 ER 降解剂 (SERD)，并且在 MCF-7 细胞中比氟维司群更有效地抑制细胞增殖。ERD-308的进一步优化可能会导致晚期ER+乳腺癌的新疗法。
