Transient receptor potential vanilloid 3 (TRPV3) is a Ca²⁺- and Na⁺-permeable channel with a unique expression pattern. TRPV3 is found in both neuronal and non-neuronal tissues, including dorsal root ganglia, spinal cord, and keratinocytes. Recent studies suggest that TRPV3 may play a role in inflammation, pain sensation, and skin disorders. TRPV3 studies have been challenging, in part due to a lack of research tools such as selective antagonists. Herein, we provide the first detailed report on the development of potent and selective TRPV3 antagonists featuring a pyridinyl methanol moiety. Systematic optimization of pharmacological, physicochemical, and ADME properties of original lead 5a resulted in identification of a novel and selective TRPV3 antagonist 74a, which demonstrated a favorable preclinical profile in two different models of neuropathic pain as well as in a reserpine model of central pain.

（吡啶-2-基）甲醇衍生物作为新型和选择性瞬态受体潜在香草醛3拮抗剂的合成与药理作用

瞬态受体电位香草酸3（TRPV3）是具有独特表达模式的Ca 2 ⁺ -和Na ^+-渗透通道。在神经元和非神经元组织（包括背根神经节，脊髓和角质形成细胞）中均发现了TRPV3。最近的研究表明，TRPV3可能在炎症，疼痛感和皮肤疾病中起作用。TRPV3研究一直具有挑战性，部分原因是缺乏诸如选择性拮抗剂之类的研究工具。在本文中，我们提供了有关开发具有吡啶基甲醇部分的有效和选择性TRPV3拮抗剂的第一份详细报告。原始铅5a的药理，理化和ADME特性的系统优化导致鉴定出新型的选择性TRPV3拮抗剂74a，在两种不同的神经性疼痛模型以及利血平中枢性疼痛模型中均显示出良好的临床前特征。
