A series of N-acyl benzothiazoles shows selective and potentcytotoxicity against cancer cell lines expressing cytochrome P450 4F11. A prodrug form is metabolized by cancer cells into an active inhibitor of stearoyl-CoA desaturase (SCD). Substantial variation on the acyl portion of the inhibitors allowed the identification of (R)-27, which balanced potency, solubility, and lipophilicity to allow proof-of-concept

Nucleoside and nucleotide analogues that can be used as cardioprotective agents are provided. The nucleosides and nucleotide analogues comprise tetrahydrofuranyl or tetrahydrothienyl moieties with quaternary stereogenic all-carbon centers at the 2' position and a phosphonate ester at the 5' position.

Ligand binding poses in the orthosteric bindingsite have been largely predicted from mutagenesis and docking studies. We report the synthesis of a series of photo-cross-linking compounds whose structures are based on the clinically used antiemetic drug granisetron (Kytril). These displaced [3H]granisetron from the orthosteric bindingsite with low nanomolar affinities and showed specific photo-cross-linking

(SSRI) (S)-citalopram that were rationally designed and synthesized to contain a photoreactive benzophenone or an aryl azide for protein target capture via photoaffinity labeling and a terminal alkyne or an aliphatic azide for click chemistry-based proteomics. Specifically, clickable benzophenone-based (S)-citalopram photoprobe 6 (hSERT Ki = 0.16 nM) displayed 11-fold higher binding affinity at hSERT
迄今为止,靶向人类血清素转运蛋白(hSERT)的光亲和配体的开发已基于放射性同位素(即3 H或125 I),hSERT是一种涉及疾病状态(如抑郁和焦虑)的关键蛋白。而是强调了选择性5-羟色胺再摄取抑制剂(SSRI)(S)-西酞普兰的三种衍生物,这些衍生物经过合理设计和合成,包含光反应性二苯甲酮或芳基叠氮化物,用于通过光亲和标记和末端炔烃或脂族叠氮化物捕获蛋白质靶标。用于基于化学点击的蛋白质组学。具体而言,可点击的基于二苯甲酮的(S)-西酞普兰光电探针6(hSERT K i =(0.16 nM)与(S)-西酞普兰(hSERT K i = 1.77 nM)相比,在hSERT处显示出11倍的高结合亲和力,随后显示使用纯化的hSERT成功地进行了串联光亲和标记-双正交偶联。给定可点击的光探针可以用于各种应用,这取决于在光亲和标记后通过点击化学将哪个报道分子连接到了报道分子上,预计光探针6将在结构
