thiazole moieties were isolated from the marinespongeDiscodermiacalyx collected near Shikine-jima Island, Japan. The structures of calyxamides A (1) and B (2), including the absolute configurations of all amino acids, were elucidated by spectroscopic analyses and degradation experiments. The structures are similar to keramamides F and G, previously isolated from Theonella sp. The analysis of the

functionalization prevalent in the biosynthesis of a diverse array of biologically active bacterial, fungal, plant, and metazoan diketopiperazine (DKP) alkaloids. Toward the development of a unified strategy for biocatalytic construction of prenylated DKP indolealkaloids, we sought to identify and characterize a substrate-permissive C2 reverse prenyltransferase (PT). As the first tailoring event within the biosynthesis
N-chloropeptide strategy for the rapid construction of ΔAA-containing peptides. The quinuclidine (ABCO)-catalyzed N-chlorination of peptide bonds and the subsequent β-elimination of N-chloroamide efficiently provides ΔAA-containing peptides in high yield. The strategy enables the late-stage installation of ΔAA motifs into already-constructed oligopeptides, including a macrocyclic peptide.

for the development of new therapeutics in neuropathic pain, acute myeloid leukemia, and inflammation. However, there is still a lack of potent, selective, and drug-like G2A agonists to be used as a chemical tool or as the starting matter for the development of drugs. In this work, we present the discovery and structure–activity relationship elucidation of a new potent and selective G2A agonist scaffold
G 蛋白偶联受体 G2A 被认为是开发神经性疼痛、急性髓性白血病和炎症新疗法的有希望的靶点。然而,仍然缺乏有效的、选择性的、类药物的G2A激动剂来用作化学工具或作为药物开发的起始物质。在这项工作中,我们展示了一种新的有效、选择性 G2A 激动剂支架的发现和结构-活性关系阐明。系统优化导致 (3-(吡啶-3-基甲氧基)苯甲酰基) -d-苯丙氨酸 (T-10418) 表现出比参考和天然配体 9-HODE 更高的效力,并且在 G 蛋白偶联受体中具有高选择性。凭借其良好的活性、清晰的选择性、优异的溶解度和高代谢稳定性,T-10418 有资格作为研究 G2A 激活效应的药理学工具。
Discovery and Structure-Based Optimization of Adenain Inhibitors
The cysteine protease adenain is the essential protease of adenovirus and, as such, represents a promising target for the treatment of ocular and other adenoviral infections. Through a concise two-pronged hit discovery approach we identified tetrapeptide nitrile 1 and pyrimidine nitrile 2 as complementary starting points for adenain inhibition. These hits enabled the first high-resolution X-ray cocrystal structures of adenain with inhibitors bound and revealed the binding mode of 1 and 2. The screening hits were optimized by a structure-guided medicinal chemistry strategy into low nanomolar drug-like inhibitors of adenain.
